Color -order systems highlight certain features of color phenomenology while neglecting others. It is misleading to speak as if there were a single “psychological color space” that might be described by a rather simple formal structure. Criticisms of functionalism based on multiple realizations of a too-simple formal description of chromatic pheno-menal relations thus miss the mark. It is quite implausible that a functional system representing the full complexity of human color phenomenology should be realizable by (...) radically different qualitative states. (shrink)

Distributional semantic models (DSMs) are a primary method for distilling semantic information from corpora. However, a key question remains: What types of semantic relations among words do DSMs detect? Prior work typically has addressed this question using limited human data that are restricted to semantic similarity and/or general semantic relatedness. We tested eight DSMs that are popular in current cognitive and psycholinguistic research (positive pointwise mutual information; global vectors; and three variations each of Skip-gram and continuous bag of words (...) (CBOW) using word, context, and mean embeddings) on a theoretically motivated, rich set of semantic relations involving words from multiple syntactic classes and spanning the abstract–concrete continuum (19 sets of ratings). We found that, overall, the DSMs are best at capturing overall semantic similarity and also can capture verb–noun thematic role relations and noun–noun event-based relations that play important roles in sentence comprehension. Interestingly, Skip-gram and CBOW performed the best in terms of capturing similarity, whereas GloVe dominated the thematic role and event-based relations. We discuss the theoretical and practical implications of our results, make recommendations for users of these models, and demonstrate significant differences in model performance on event-based relations.

A single case study of a patient, D.M., with a lesion in the region of the right occipito-temporal gyrus is presented. D.M. had well-preserved language and general cognitive abilities. Colour discrimination, contrast sensitivity, gross depth perception, spatial localization, and motion appreciation were within normal limits.On the evaluation of perceptual abilities, he failed to identify two-dimensional shapes from stereoscopic vision, motion, and texture although in all cases he was able to identify the rough area subtended by the shape. These findings are (...) considered in relation to the current anatomical-physiological functional models of vision and it is suggested that D.M. 's deficits provide evidence for the existence in man of a functional pathway involved in the computation of texture and fine aspects of shape, which is distinct from the pathways involved in motion and stereopsis processing on one hand and colour and coarse aspects of form on the other hand.

Tracking theories of mental representation posit a privileged relation between color representations and the color properties of objects. Tracking theories of mental representation have been used to motivate color realism as they posit that the function of color vision is to represent the colors of objects. It has been argued that tracking theories have a major flaw, namely they cannot account for reliable misrepresentation. It has further been suggested that reliable color misrepresentation is a live (...) possibility. In this chapter, I argue that the current evidence indicates that our color representations reliably misrepresent. This conclusion undermines tracking theories and the color realist theories they purport to motivate. (shrink)

Much research on color representation and categorization has assumed that relations among color terms can be proxies for relations among color percepts. We test this assumption by comparing the mapping of color words with color appearances among different observer groups performing cognitive tasks: an invariance of naming task; and triad similarity judgments of color term and color appearance stimuli within and across color categories. Observer subgroups were defined by perceptual phenotype (...) and photopigment opsin genotype analyses. Results suggest that individuals rely on at least two different representational models of color experience: one lexical, conforming to the culture's normative linguistic representation, and another individual perceptual representation organizing each observer's color sensation experiences. Additional observer subgroup analyses suggest that perceptual phenotype variation within a language group may play a greater role in the shared color naming system than previously thought. A reexamination of color naming data in view of these findings may reveal influences on color naming important to current theories. (shrink)

What is the function of color vision? In this paper, I focus on perceptual phenomena studied in psychophysics and argue that the best explanation for these phenomena is that the color visual system is a perceptual enhancement system. I first introduce two rival conceptions of the function of color vision: that color vision aims to detect or track the fine-grained colors of distal objects and scenes (Seeing Color) and that it aims to help organisms discriminate, (...) detect, track and/or recognize ecologically important objects, properties, and relations more directly (Seeing with Color). I then discuss two kinds of systematic perceptual phenomena investigated by psychophysicists: approximate color constancy and color induction. I argue from the premise that Seeing with Color better accommodates and explains these phenomena to the conclusion that it is the conception that an empirically-guided philosopher of color ought to adopt.

Properties like mass and temperature can be ordered on metrical scales. A property like hardness can perhaps only be ordered on an ordinal scale. Geometrical shapes seem to admit ordinal scales only in relation to specifically chosen families of shapes. The main claims of this paper are.

My aim in this paper is to defend the view that the processes underlying early vision are informationally encapsulated. Following Marr (1982) and Pylyshyn (1999) I take early vision to be a cognitive process that takes sensory information as its input and produces the so-called primal sketches or shallow visual outputs: informational states that represent visual objects in terms of their shape, location, size, colour and luminosity. Recently, some researchers (Schirillo 1999, Macpherson 2012) have attempted to undermine the idea of (...) the informational encapsulation of early vision by referring to experiments that seem to show that colour recognition is affected by the subject's beliefs about the typical colour of objects. In my view, however, one can reconcile the results of these experiments with the position that early vision is informationally encapsulated. Namely, I put fort a hypothesis according to which the early vision system has access to a local database that I call the mental palette and define as a network of associative links whose nodes stands for shapes and colours. The function of the palette is to facilitate colour recognition without employing central processes. I also describe two experiments by which the mental palette hypothesis can be tested. (shrink)

The Chinese Mādhyamikas Seng Zhao 374–414, Jizang 549–623, and Zhiyi 538–597 try to demonstrate that the linguistic strategies in the textual transmission of the Buddha’s teaching give us access to a sense of “liberation” which reaches beyond language. For them, this ineffable sense is what constitutes the dharma in the shape of sūtra and śāstra. Liberation is considered the constitutive but hidden “root” of all the teachings transmitted via the canonical word, those again account for the Buddha’s “traces” guiding back (...) to the meaning of that root. The practitioner’s comprehension of the dharma must embrace this circular mutuality of “root and traces,” reconciling speech with silence. The article discusses two philosophical aspects: Chinese Madhyamaka semantics and pragmatics exploring the various signifying functions in our use of language, and the hermeneutical approach that the Chinese masters develop in their exegetical works to unravel such a sense of “liberation” in reference to the textual transmission of Indian Mahāyāna thought.

There is growing evidence of evolutionary genome plasticity. The evolution of repetitive DNA elements, the major components of most eukaryotic genomes, involves the amplification of various classes of mobile genetic elements, the expansion of satellite DNA, the transfer of fragments or entire organellar genomes and may have connections with viruses. In addition to various repetitive DNA elements, a plethora of large and small RNAs migrate within and between cells during individual development as well as during evolution and contribute to changes (...) of genome structure and function. Such migration of DNA and RNA molecules often results in horizontal gene transfer, thus shaping the whole genomic network of interconnected species. Here, we propose that a high evolutionary dynamism of repetitive genome components is often related to the migration/movement of DNA or RNA molecules. We speculate that the cytoplasm is probably an ideal compartment for such evolutionary experiments. (shrink)

_Abstract_: This paper aims to propose a relational approach to the study of cognition that can offer a perspective on the cognitive behaviours of plants – sessile organisms without a nervous system – when considered in the reciprocal interrogation of philosophy and the cognitive and ecological sciences. When leveraging the inspiring, clarifying, and occasionally heuristic potential of different epistemic tools, plant cognition can be understood as the result of processes constantly shaped by multiple co-constructive relationships between organisms and their ecological (...) niches. Organisms and niches are conceivable as dense multi-functional systems of resources and information interchange. The concepts of network and ramification are fruitful keys to frame forms of dynamic relationships between elements. In their alternatively iconical, metaphorical, and conceptual-modelling potentialities, networks and ramifications have been used to identify different types of relationships and transmitted information. The explanatory and heuristic scope of these two concepts needs to be further investigated when linked to cognitive aspects, especially with regard the concept of ramification. Looking at the plant world, whilst much has been written about networks, relatively little has been said explicitly about ramifications (branching capacity, branching characteristics and habits) and their relationship with aspects related to plant behaviour and cognition. _Keywords_: Plant Cognition; Ramifications; Networks; Ecology; Cognitive Science _Reti e ramificazioni: prospettive relazionali nello studio della cognizione vegetale _ _Riassunto_: Questo lavoro intende proporre un approccio relazionale allo studio della cognizione che possa offrire una prospettiva sui comportamenti cognitivi delle piante – organismi sessili privi di sistema nervoso – considerati dalla prospettiva filosofica e delle scienze cognitive ed ecologiche. Dato il potenziale ispiratore, chiarificatore e a volte euristico dei diversi strumenti epistemici, la cognizione delle piante può essere vista come risultato di processi costantemente plasmati da molteplici relazioni co-costruttive tra gli organismi e le loro nicchie ecologiche. Organismi e nicchie sono infatti concepibili come un denso sistema multi-funzionale di scambio di risorse e informazioni. I concetti di rete e ramificazione sono utili chiavi di lettura per inquadrare forme di relazione dinamica tra elementi. Nelle loro potenzialità iconiche, metaforiche e concettuali, le reti e le ramificazioni sono state usate per identificare diversi tipi di relazioni e informazioni trasmesse. Lo scopo esplicativo ed euristico di questi due concetti necessita di essere ulteriormente indagato, quando legato agli aspetti cognitivi, specialmente per quanto riguarda il concetto di ramificazione. Guardando il mondo vegetale, mentre molto è stato scritto sulle reti relativamente poco si è detto esplicitamente sulle ramificazioni (capacità di ramificazione, caratteristiche e abitudini di ramificazione) e sulle loro relazioni con aspetti legati al comportamento e alla cognizione. _Parole chiave_: Cognizione vegetale; Ramificazioni; Reti; Ecologia; Scienza cognitiva.

It seems intuitively obvious that metameric matching of color samples entails a loss of information, for spectrophotometrically diverse materials appear the same. This intuition implicitly relies on a conception of the function of color vision and on a related conception of how color samples should be individuated. It assumes that the function of color vision is to distinguish among spectral energy distributions, and that color samples should be individuated by their physical properties. I challenge these (...) assumptions by articulating a different conception of the function of color vision, according to which color vision serves to partition object surfaces into discrimination classes.

The mainstream view in contemporary analytic philosophy is that perception is primarily in the business of representing the mind-independent world as it is. My dissertation explores an alternative conception: that the goal of perception is to guide successful action and that perceptions do not need to track mind-independent properties to play this action-guiding role. I focus on two types of perception: color perception and pain perception. I start with the former and advocate a pragmatist, empirically-guided approach which begins by (...) inquiring into the function of color vision. After arguing that none of the extant philosophical views of color are satisfactory, I answer the function question by focusing on systematic color perceptual phenomena investigated by psychophysicists. I argue that the human color visual system is an enhancement system: that is, its job is to help us better discriminate, track, and recognize meaningful objects, properties, and relations. I then build on this idea using the notion of ‘competence-embeddedness.’ I propose that color vision is embedded in a network of competences: the aim of color vision is to help organisms manifest these competences, and color experiences are correct when they result from competence-enhancing processing. The framework is explanatorily robust. For example, it allows me to conceptualize many textbook color illusions as special cases of successful color perception where the demands of the relevant competences clash. Finally, I use the notion of ‘competence-embeddedness’ to develop a new account of pain. I argue that the pain system is not a bodily disturbance detector, but a sophisticated, context-responsive security system whose primary goal is to help organisms manifest important behavioral and cognitive competences.

Despite decades of research, morphogenesis along the various body axes remains one of the major mysteries in developmental biology. A milestone in the field was the realisation that a set of closely related regulators, called Hox genes, specifies the identity of body segments along the anterior–posterior (AP) axis in most animals. Hox genes have been highly conserved throughout metazoan evolution and code for homeodomain‐containing transcription factors. Thus, they exert their function mainly through activation or repression of downstream genes. However, while (...) much is known about Hox gene structure and molecular function, only a few target genes have been identified and studied in detail. Our knowledge of Hox downstream genes is therefore far from complete and consequently Hox‐controlled morphogenesis is still poorly understood. Genome‐wide approaches have facilitated the identification of large numbers of Hox downstream genes both in Drosophila and vertebrates, and represent a crucial step towards a comprehensive understanding of how Hox proteins drive morphological diversification. In this review, we focus on the role of Hox genes in shaping segmental morphologies along the AP axis in Drosophila, discuss some of the conclusions drawn from analyses of large target gene sets and highlight methods that could be used to gain a more thorough understanding of Hox molecular function. In addition, the mechanisms of Hox target gene regulation are considered with special emphasis on recent findings and their implications for Hox protein specificity in the context of the whole organism.

Between-subject variability in cognitive performance has been related to inter-individual differences in functional brain networks. Targeting the dorsal attention network we questioned whether resting-state functional connectivity within the DAN can predict individual performance in spatial attention tasks and whether there is short-term adaptation of DAN-FC in response to task engagement. Twenty-seven participants first underwent resting-state fMRI, they subsequently performed different tasks of spatial attention [including visual search ] and immediately afterwards received another rs-fMRI. Intra- and inter-hemispheric FC between core hubs (...) of the DAN, bilateral intraparietal sulcus and frontal eye field, was analyzed and compared between PRE and POST. Furthermore, we investigated rs-fMRI-behavior correlations between the DAN-FC in PRE/POST and task performance parameters. The absolute DAN-FC did not change from PRE to POST. However, different significant rs-fMRI-behavior correlations were revealed for intra-/inter-hemispheric connections in the PRE and POST run. The stronger the FC between left FEF and IPS before task engagement, the better was the learning effect in VS. And the faster the VS, the stronger was the FC between right FEF and IPS after task engagement. To conclude, DAN-FC relates to the individual performance in spatial attention tasks supporting the view of functional brain networks as priors for cognitive ability. Despite a high inter- and intra-individual stability of DAN-FC, the change of FC-behavior correlations after task performance possibly indicates task-related adaptation of the DAN, underlining that behavioral experiences may shape intrinsic brain activity. However, spontaneous state fluctuations of the DAN-FC over time cannot be fully ruled out as an alternative explanation. (shrink)

Colour relationalism holds that the colours are constituted by relations to subjects. Anti-relationalists have claimed that this view stands in stark contrast to our phenomenally-informed, pre-theoretic intuitions. Is this claim right? Cohen and Nichols’ recent empirical study suggests not, as about half of their participants seemed to be relationalists about colour. Despite Cohen and Nichols’ study, we think that the anti-relationalist’s claim is correct. We explain why there are good reasons to suspect that Cohen and Nichols’ experimental design skewed (...) their results in favour of relationalism. We then run an improved study and find that most of our participants seem to be anti-relationalists. We find some other interesting things too. Our results suggest that the majority of ordinary people find it no less intuitive that colours are objective than that shapes are objective. We also find some evidence that when those with little philosophical training are asked about the colours of objects, their intuitions about colour and shape cases are similar, but when asked about people’s colour ascriptions, their intuitions about colour and shape cases differ.

No crucial experiment demonstrates that four hue categories are needed to describe color appearance. Instead, converging lines of evidence suggest that the terms red, yellow, green, and blue are sufficient and precise enough for deriving color discrimination functions and for a useful model constraining relations between color appearance and neuronal responses. Such a model need not be based on linguistic universals. Until something better is available, this holds.

A compositional theory of perceptual representations would explain how the accuracy conditions of a given type of perceptual state depend on the contents of constituent perceptual representations and the way those constituents are structurally related. Such a theory would offer a basic framework for understanding the nature, grounds, and epistemic significance of perception. But an adequate semantics of perceptual representations must accommodate the holistic nature of perception. In particular, perception is replete with context effects, in which the way one perceptually (...) represents one aspect of a scene (including the position, size, orientation, shape, color, motion, or even unity of an object) normally depends on how one represents many other aspects of the scene. The ability of existing accounts of the semantics of perception to analyze context effects is at best unclear. Context effects have even been thought to call into question the very feasibility of a systematic semantics of perception. After outlining a compositional semantics for a rudimentary set of percepts, I draw on empirical models from perceptual psychology to show how such a theory must be modified to analyze context effects. Context effects arise from substantive constraints on how perceptual representations can combine and from the different semantic roles that perceptual representations can have. I suggest that context effects are closely tied to the objectivity of perception. They arise from a perceptual grammar that functions to facilitate the composition of reliably accurate representations in an uncertain but structured world. (shrink)

While the agricultural knowledges and practices of Black, Indigenous, and People of Color and women have shaped agriculture in the US, these knowledges have been colonized, exploited, and appropriated, cleaving space for the presently dominant white male agricultural narrative. Simultaneously, these knowledges and practices have been transformed to fit within a society that values individualism, production, efficiency, and profit. The authors use a decolonial Feminist Political Ecology framework to highlight the ways in which the knowledges of Indigenous, Black, and (...) women farmers have been and are being colonized; a tradition that makes alternative agriculture a predominantly white space. The authors interviewed 10 BIPOC and women farmers in Colorado to understand what values and knowledges were shaping their often-appropriated agricultural practices. Three themes emerged: people, place, and patterns. By centering these values, farmers create relational agricultural practices that support the well-being of human and more-than-human beings. To support the widespread implementation of these practices, food systems practitioners must elevate the voices and knowledges of historically excluded farmers. Only then can truly just and equitable alternative agricultural practices be realized in the US. (shrink)

What is the relation between Kanizsa's bias towards convexity and the Gestaltists' demonstrations that perceptual organization obeys a principle of pragnänz, or simplicity? Why should either kind of bias exist? Textbook accounts assign no functional role for these biases. Geon theory (Biederman 1987) proposes that we can understand these biases in terms of fundamental processes by which complex objects are decomposed into convex (or singly concave) regions at points of matched cusps according to the transversality regularity (Hoffman and Richards 1985). (...) Such decomposition yields simple, convex parts segmented between the concavities. A shape that contains concavities is generally regarded as complex insofar as it can be decomposed into the regions, or parts, between the concavities. It is these simple parts that are the stable elements of shape, not the whole object. In fact, geon theory leads to the expectation that shape recognition proceeds most efficiently when the parts are good (in the pragnänz sense) but the object is bad! (shrink)

Little is known about people’s perceived benefits and risks of sports, despite their role in shaping people’s intentions to engage in them. Here, we developed and tested a scale to measure perceived physical, emotional, cognitive, and social benefits as well as aggression-related risks of karate and football. Additionally, we compared these perceptions within and between these two sports, as well as among undergraduates with current/former participation in different types of physical activity. After a literature review, we created a 5-factor scale (...) with 20 items administered to 184 undergraduates, along with questions about physical activity participation. After removing five items, confirmatory factor analyses supported the factor structure of the scale. Factor loadings and reliability indices were acceptable, though less than desirable results were found concerning the average variance extracted of all benefits dimensions and the reliability of the social benefits dimension. Analyses of variance showed that: physical benefits were seen as the salient outcomes of karate and football, though martial artists perceived karate’s physical, emotional, and social benefits to the same extent; in comparison to football, karate was perceived to bring more emotional and cognitive benefits and to entail less aggressiveness risks; karate and football perceptions varied as a function of participant’s involvement in physical activity. This study presents a promising instrument to gather information on people’s perceptions about karate and football, which can be used to foster people’s engagement in them. (shrink)

We can perceive shapes visually and tactilely, and the information we gain about shapes through both sensory modalities is integrated smoothly into and functions in the same way in our behavior independently of whether we gain it by sight or touch. There seems to be no reason in principle we couldn't perceive shapes through other sensory modalities as well, although as a matter of fact we do not. While we can identify shapes through other sensory modalities—e.g., I may know by (...) smell (the scent of mango) that the object causing my sensory experience is round—this is not perceiving an object as shaped, but rather inferring from the character of one's sensory experience and collateral information that an object of a certain shape caused it. That it is possible to perceive shape by other modalities, however, is suggested by the case of bats and aquatic mammals like dolphins which navigate through their environment by a form of sonar. It is plausible that they have some form of auditory representation of space, and so of shape. These facts about shape perception raise important questions about the relation between those features of perceptual experience which are intrinsic to different sensory modalities and the nature of our perceptual representation of shapes, and, more generally, of the space within which we perceive shaped objects to be located. John Campbell's paper, "Molyneux's Problem" (see above), raises a number of interesting and important questions about the nature of our perception of shape properties, particularly the cross-modal nature of shape perception, and ties them to more general questions about the nature both of perceptual..

Odor and color are strongly associated. Numerous studies demonstrate consistent odor‐color associations, as well as effects of color on odor perception and language. Yet, we know little about how these associations arise. Here, we test whether language is a possible mediator of odor‐color associations, specifically whether odor‐color associations are mediated by implicit odor naming. In two experiments, we used an interference paradigm to prevent the verbalization of odors during an odor‐color matching task. If participants (...) generate color associations subsequent to labeling an odor, interfering with verbalization during the task should affect the ability to make color associations. In Experiment 1, contrary to our hypothesis, verbal interference did not affect odor‐color matches. However, since performance accuracy on the verbal interference task was high, it is possible our task did not sufficiently disrupt verbal processing. In Experiment 2, we, therefore, used an active verbal interference task, and still found no difference across interference conditions. Odor naming accuracy, odor familiarity, and odor pleasantness, however, did predict odor‐color matches. This suggests that although color associations are related to semantic factors, they are not generated by recruiting odor labels in the moment. Overall, our results do not provide evidence that language plays an online role in odor‐color associations, instead, they are consistent with the claim that language may have shaped associations during development.

Throughout his career, Michael Bratman has developed a detailed model of individual ‘planning agency’, and, more recently, models of joint action and aspects of social life that he argues such planning agency helps support. How might we empirically investigate whether these models capture what is going on in actual human lives? In this article, we critically engage with this broad question by focusing on what Bratman calls the ‘core capacity thesis’, which is at the center of his most recent discussions (...) of how his work in the philosophy of action hangs together. In his own words, the core capacity thesis claims that ‘our capacity for planning agency plays basic roles in multiple, interrelated systems of human, mind-shaped practical organization, individual and social’. We explore how one might go about testing this thesis, focusing on Bratman's particular way of defending this thesis using the idea of ‘nested Cummins functions’. In so doing, we hope to contribute to a broader discussion about what the relationship is (or, perhaps more importantly, should be) between the kind of philosophy of action Bratman does and empirical work in fields such as psychology, cognitive science, and biology.

In Regina v. Murray, (2000, Ont S.Ct.J.) the learned trial judge, Justice Gravely, errs in his interpretation and application of the law of mens rea in the offense of willfully attempting to obstruct justice under section 139(2) of the Criminal Code of Canada. In view of his findings of fact and law, including the determination that the accused knowingly and intentionally committed the actus reus of the offense and the absence of any suggestion that he lacked awareness of any relevant (...) facts, there is no question in law but that Kenneth Murray was liable to be, and actually should have been, convicted. Nonetheless, the trial judge concluded that Murray’s alleged belief, that his actions were required by his duty to his client, raised a reasonable doubt about his intention to obstruct justice and entitled him to be acquitted. -/- In his reasons for judgment, the trial judge analyzes mens rea as if there is a “color of right” defense to the offense of obstruction of justice. In law, however, no such defense exists to this offense. Consequently, even if Mr. Murray did “honestly believe” that he had a duty to his client not to disclose the existence of the video tapes, that belief could not provide him with an exculpatory defence. In Canada, pursuant to common law and section 19 of the Criminal Code, mistakes of law do not excuse accused persons from responsibility for criminal conduct in the absence of a statutory exception. No exception exists for the offense of obstruction of justice. Yet the Crown did not choose to appeal and thereby signaled its acceptance of the legal analysis adopted by the trial judge. By contrast, if the analysis proposed in this piece had been adopted, the Crown should have prevailed at trial and, if unsuccessful at trial, would have had a right of appeal on a question of law. -/- At least two tendencies converge as significant influences shaping the outcome in the Murray case. The central tendency, discussed in Part I of this article, is the trial judge’s treatment of the accused’s alleged mistake about his legal duty as if it were a mistake about a question of fact which therefore could give rise to a reasonable doubt about intention or culpable awareness. This approach to mistaken beliefs ignores the distinction between mistakes of law and mistakes of fact, and then characterizes all mistakes as mistakes of fact. Unfortunately, this is not uncommon in the case law. In recent years however, as explained below, the judiciary has rejected that approach in a number of leading cases and ruled that mistakes which are actually mistakes about the meaning, scope, or application of the law are subject to the general rule and do not provide an accused with an exculpatory defense. The relationship between mistake of law and mens rea in Canadian criminal law has also been the subject of critical scholarly comment in Canada in recent years. The Murray decision provides evidence that, despite clarification by the Supreme Court, in some lower courts the unrefined approach to mistaken belief continues to shape the legal analysis of criminal culpability, even when the mistaken belief is overtly a belief about the law. This will not change until the proper characterization of mistaken beliefs as legal or factual becomes a deliberate and common-place aspect of case analysis at the trial court level. -/- The other tendency, discussed in Part III of this article, is one that often appears as a companion to the first - the judicial tendency to perceive and invoke analytical legal ambiguity in favour of accuseds more readily in cases in which the impugned conduct involves the discretionary exercise of authority which, when used appropriately, is fully legitimate and essential to the normal functioning of the existing socio-legal order. Of course, courts are strongly influenced by the arguments put to them by counsel. And counsel, acting on behalf of client groups with particular group interests may, consciously or unconsciously, favour the development of those lines of analysis which are protective of that interest or associated institutional interests. One of the reasons for scrutinizing the Murray case is that it provides a concrete context for discussion of those issues in relation to an actual decision made by Crown prosecutors. The case provides an occasion to examine a specific example of the exercise of prosecutorial discretion, its implications for the administration of criminal justice, and its broader potential impact on the public interest.

Functional contexts have long been recognized to support evaluative judgments of a certain kind, even where there is no element of design: we speak, for example, of such things as good roots or defective hearts in connection with judgments about proper functions; an animal might even be judged defective for failing to possess a certain species-typical, functional behavioral disposition. These are obviously not moral judgments, but it is interesting to wonder whether the latter might be understood in a similar way. (...) Can moral virtues, for example, be understood as dispositions to function properly in certain spheres of human life involving the will, so that someone lacking them might be said to have a defective character? ;One possibly tempting way of pursuing this broadly Aristotelian line, which has been proposed in recent work by Philippa Foot, would be to argue that there is a single type of functional framework within which to understand both function-related evaluations in biology generally, and function-related evaluations pertaining to ethics and practical rationality; in both cases, it might be thought, talk of species-typical functions and proper functioning is to be understood in relation to the flourishing of the organisms in question, the difference being that the functions relevant to ethics would involve the will. ;I argue that this way of fleshing out a neo-Aristotelian approach to ethics and practical rationality is misguided. Much of the dissertation is devoted to showing this by developing a positive account of functional teleology in biology which makes clear that the flourishing or welfare-promotion of organisms is neither a general nor an ultimate end within the biological functional framework. The view I defend recognizes the crucial role played by natural selection history in shaping facts about present functional teleology, but it is importantly different from what are generally known as "etiological" views. In particular, it does not involve any direct reduction of facts about function to facts about causal history, and it suggests a non-reductionist view of functional teleological explanation, which I also defend. The rejection of etiological views of function in general leaves open the possibility that there is some kind of functional framework, distinct from the biological one, that might be relevant to ethics; I explore this in the last chapter.

Intra-individual variability (IIV) refers to within-person variability in behavioural task responses. Several factors can influence IIV, including aging and cognitive demands. The present study investigated effects of aging on IIV of response times during executive functioning tasks. Known age-related differences in cognitive control and emotion processing motivated evaluating how varying the design of emotional response inhibition tasks would influence IIV in older and younger adults. We also tested whether IIV predicted inhibitory control across task designs and age groups. Older and (...) younger adults (N = 237) completed one of three versions of a stop-signal task, which all displayed happy, fearful, or neutral faces in Stop trials. An independent group of older and younger adults (N = 80) completed a go/no-go task also employing happy, fearful and neutral faces. Results showed older adults had more consistent responses (lower IIV) than younger adults in the stop-signal task, but not the go/no-go task. Lower IIV predicted more efficient emotional response inhibition for fear faces in the stop-signal task, but only when attention to emotion was task-relevant. Collectively, this study clarifies effects of aging and task design on IIV and illustrates how task design impacts the relationship between IIV and emotional response inhibition in younger and older adults.

We give a new and elementary construction of primitive positive decomposition of higher arity relations into binary relations on finite domains. Such decompositions come up in applications to constraint satisfaction problems, clone theory and relational databases. The construction exploits functional completeness of 2-input functions in many-valued logic by interpreting relations as graphs of partially defined multivalued ‘functions’. The ‘functions’ are then composed from ordinary functions in the usual sense. The construction is computationally effective and relies on well-developed (...) methods of functional decomposition, but reduces relations only to ternary relations. An additional construction then decomposes ternary into binary relations, also effectively, by converting certain disjunctions into existential quantifications. The result gives a uniform proof of Peirce’s reduction thesis on finite domains, and shows that the graph of any Sheffer function composes all relations there. (shrink)

Oxford University Press, Oxford, pp 157–172, 2002), one of the main proponents of the causal role account of biological functions, argues that a correctly understood neo-Darwinian notion of natural (...) selection has nothing to do with functional talk in biology. In this paper, we counter Cummins’ account by showing that progress in the molecular approaches to evolutionary biology—specifically scientific data available in neo-functionalization research—offers valuable support to the etiological selectionist approach to functions in biological and biologically-related sciences. Finally, we use the presented data to build our own account of biological functions, which tries to avoid the wrong turns taken by both major strands in the biological function debate, namely causal role and etiological accounts. According to our account, the function of a certain gene or a protein in the biological system that contains it is a particular causal activity, or a group of causal activities whose manifestation is in a specific way determined by corresponding mechanisms of genetic expression. Also, we argue that in many important cases this particular expression of genetic activity was positively selected at a certain point in evolutionary history. Since we take selection as an important but not the only factor that grounds biological functions, we are committed to a weak etiological account. (shrink)

Research on electroencephalogram (EEG) characteristics associated with major depressive disorder (MDD) has accumulated diverse neurophysiologic findings related to the content, topography, neurochemistry, and functions of EEG oscillations. Significant progress has been made since the first landmark EEG study on affective disorders by Davidson 35 years ago. A systematic account of these data is important and necessary for building a consistent neuropsychophysiologic model of MDD and other affective disorders. Given the extensive data on frequency-dependent functional significance of EEG oscillations, a frequency (...) domain approach may reveal the types of brain functions involved and disturbed in MDD. In this review, we systematize and integrate diverse and often unconnected observations on the content, topography, neurochemistry, and functions of EEG oscillations involved in MDD within the general concept of an EEG oscillatory pattern.

Functional information means an encoded network of functions in living organisms from molecular signaling pathways to an organism’s behavior. It is represented by two components: code and an interpretation system, which together form a self-sustaining semantic closure. Semantic closure allows some freedom between components because small variations of the code are still interpretable. The interpretation system consists of inference rules that control the correspondence between the code and the function (phenotype) and determines the shape of the fitness landscape. The utility (...) factor operates at multiple time scales: short-term selection drives evolution towards higher survival and reproduction rate within a given fitness landscape, and long-term selection favors those fitness landscapes that support adaptability and lead to evolutionary expansion of certain lineages. Inference rules make short-term selection possible by shaping the fitness landscape and defining possible directions of evolution, but they are under control of the long-term selection of lineages. Communication normally occurs within a set of agents with compatible interpretation systems, which I call communication system. Functional information cannot be directly transferred between communication systems with incompatible inference rules. Each biological species is a genetic communication system that carries unique functional information together with inference rules that determine evolutionary directions and constraints. This view of the relation between utility and inference can resolve the conflict between realism/positivism and pragmatism. Realism overemphasizes the role of inference in evolution of human knowledge because it assumes that logic is embedded in reality. Pragmatism substitutes usefulness for truth and therefore ignores the advantage of inference. The proposed concept of evolutionary pragmatism rejects the idea that logic is embedded in reality; instead, inference rules are constructed within each communication system to represent reality, and they evolve towards higher adaptability on a long time scale.

Shepard's analysis of how shape, motion, and color are perceptually represented can be generalized. Apparent motion and shape may be associated with a group of spatial transformations, accounting for rigid and plastic motion, and perceived object color may be associated with a group of illuminant transformations, accounting for the discriminability of surface-reflectance changes and illuminant changes beyond daylight. The phenomenological and mathematical parallels between these perceptual domains may indicate common organizational rules, rather than specific ecological adaptations. [Barlow; Hecht; (...)

Three experiments investigated changes from 15 to 30 months of age in children’s (N = 114) mastery of relations between an object and an aperture, supporting surface, or form. When choosing between objects to insert into an aperture, older children selected objects of an appropriate size and shape, but younger children showed little selectivity. Further experiments probed the sources of younger children’s difficulty by comparing children’s performance placing a target object in a hole, on a 2-dimensional form, or atop (...) another solid object. Together, the findings suggest that some factors limiting adults’ object representations, including the difficulty of comparing the shapes of positive and negative spaces and of representing shapes in 3 dimensions, contribute to young children’s errors in manipulating objects.

Previous research has demonstrated how emotion resembling cues in the face help shape impression formation. Perhaps most notable in the literature to date, has been work suggesting that gender-related appearance cues are visually confounded with certain stereotypic expressive cues. Only a couple studies to date have used computer vision to directly map out and test facial structural resemblance to emotion expressions using facial landmark coordinates to estimate face shape. In one study using a Bayesian network classifier trained to detect emotional (...) expressions structural resemblance to a specific expression on a non-expressive face was found to influence trait impressions of others. In another study, a connectionist model trained to detect emotional expressions found different emotion-resembling cues in male vs. female faces. Despite this seminal work, direct evidence confirming the theoretical assertion that humans likewise utilize these emotion-resembling cues when forming impressions has been lacking. Across four studies, we replicate and extend these prior findings using new advances in computer vision to examine gender-related, emotion-resembling structure, color, and texture and their impact on gender-stereotypic impression formation. We show that all three are meaningfully related to human impressions of emotionally neutral faces. Further when applying the computer vision algorithms to experimentally manipulate faces, we show that humans derive similar impressions from them as did the computer. (shrink)

Background and Objective: Understanding how trauma impacts the self-structure of individuals suffering from the Post-Traumatic Stress Disorder (PTSD) symptoms is a complex matter and despite several attempts to explain the relationship between trauma and the “Self”, this issue still lacks clarity. Therefore, adopting a new theoretical perspective may help understand PTSD deeper and to shed light on the underlying psychophysiological mechanisms. Methods: In this study, we employed the “three-dimensional construct model of the experiential selfhood” where three major components of selfhood (...) (phenomenal first-person agency, embodiment, and reflection/narration) are related to three Operational Modules (OMs) of the self-referential brain network. These modules can be reliably estimated through operational synchrony analysis of the Electroencephalogram (EEG). Six individuals with PTSD symptoms and twenty-nine sex-, age- and demographic- (race, education, marital status) matched healthy controls underwent resting state EEG signal acquisition with the following estimation of the synchrony strength within every OM. Results: Our results indicate that subjects with PTSD symptoms had significantly stronger EEG operational synchrony within anterior and right posterior OMs as well as significantly weaker EEG operational synchrony within left posterior OM compared to healthy controls. Moreover, increased the functional integrity of the anterior OM was positively associated with hyperactivity symptoms, reduced synchrony of the left posterior OM was associated with greater avoidance, and increased right posterior OM integrity was positively correlated with intrusion and mood symptoms. Conclusion: The results are interpreted in light of the triad model of selfhood and its theoretical and clinical implications (including a new treatment approach) are discussed. (shrink)

This paper concerns the structure of appearances. I argue that to be appeared to in a certain way is to be aware of one or more universals. Universals therefore function like the sense‐data, once highly favoured but now out of fashion. For instance, to be appeared to treely, in a visual way, is to be aware of the complex relation, being tree‐shaped and tree‐coloured and being in front of, a relation of a kind which could be instantiated by a material (...) object and a perceiver, which is thus instantiated in the veridical case but not in the non‐veridical.

The domain of early hominin stone tool making and tool using abilities has received little scholarly attention in mainstream philosophy of technology. This is despite the fact that archeological evidence of stone tools is widely seen today as a crucial source of information about the evolution of human cognition. There is a considerable archeological literature on the cognitive dimensions of specific hominin technical activities. However, within archeology and the study of human evolution the standard perception is stone tools are mere (...) products of the human mind. A number of recent approaches to cognition challenges this simplistic one-way-causal-arrow view and emphasizes instead the functional efficiency of tools or artifacts in transforming and augmenting human cognitive capacities. As a result, the very idea that tools or artifacts are intimately tied to human cognitive processes is fast becoming an alternative within the cognitive sciences and a few allied disciplines. The present study intends to explore its implications for philosophy of technology. The central objective of this paper is to examine the dynamic and intricate tool-mediated activities of the early hominins through the lens of Don Ihde’s post-phenomenological theory of human-technology relations and Lambros Malafouris’ Material Engagement Theory. Highlighting the key points where these two research approaches, despite their subtle nuances, converge and look capable of mutually catalyzing each other, the paper attempts to show why it is important to bring these approaches together for a more refined understanding of the controversial role these stone tools played in human evolution.

Our capacity for planning agency is a core capacity that underlies interrelated forms of mind-shaped practical organization: cross-temporal organization of individual agency, shared agency, social rules, and rule-guided organized institutions. A function of our capacity for planning agency is the support of these forms of practical organization. I highlight Peter Godfrey-Smith's contrast between the ‘Wright function’ of something as ‘the effect it has which explains why it is there’ and ‘Cummins functions’ that ‘are capacities or effects of components of systems, (...) which are salient in the explanation of capacities of the larger system’. Drawing on Paul Grice's strategy of ‘creature construction’, I articulate a sequence of nested constructions: from temporally extended planning agency to shared agency to shared policies to social rules to rule-guided organized institutions. We see our capacity for planning agency as part of an explanation of how we achieve such practical organization, and as having nested Cummins functions of supporting those forms of organization. This sheds light on related ideas in H.L.A. Hart's theory of law, a challenge from J. David Velleman, the centrality of such forms of organization to the philosophy of action, and the moral and political significance of our capacity for planning agency. (shrink)

One way to track the many critical impacts of women of color feminisms is through the powerful structural analyses of gendered and racialized oppression they offer. This article discusses diverse lineages of women of color feminisms in the global South that tackle systemic structures of power and domination from their situated perspectives. It offers an introduction to structuralist theories in the humanities and differentiates them from women of color feminist theorizing, which begins analyses of structures from embodied (...) and phenomenological st¬¬andpoints--with the day-to-day concerns of our lives. The essay is divided into three sections. In section one, I discuss theories of structure in the humanities and sciences, differentiating them from women of color’s analysis of structure as diagnostic of the ways colonial power relations are functionalized through social structures. In section two, I discuss the diverse contexts of interpretation that background women of color feminisms, outlining key themes and ideas related to theories of structure. I argue against a unified theory of women of color structural feminisms that supplants difference, favoring a rehabilitated concept of structure for the purposes of making targeted interventions in contemporary radical anti-colonial politics. I offer the example of systematic marginalization produced by colonial violence and mythology as one reason to take up this approach. In section three, I outline four provisional characteristics of women of color structural feminisms. I conclude that, when divested from colonial myths that guide mainstream notions of structure, it can be a useful hermeneutic tactic in the fight for liberation from ongoing colonial violence.

In his critique of egoism as a doctrine of ends, G. E. Moore famously challenges the idea that something can be someone. Donald Regan has recently revived and developed the Moorean challenge, making explicit its implications for the very idea of individual welfare. If the Moorean is right, there is no distinct, normative property good for, and so no plausible objectivism about ethics could be welfarist. In this essay, I undertake to address the Moorean challenge, clarifying our theoretical alternatives so (...) that we may better decide what to admit into our moral ontology and better assess what may be at stake in whether objectivists treat good or good for (or neither) as fundamental. I compare the Moorean and welfarist pictures of value, providing an account of the form and function of good for. According to this account expresses a distinct relational value that has its source in the value of persons. Good for value is thus a form of extrinsic value that provides agent-neutral reasons for action, and it plays a pervasive normative role in regulating child rearing, guiding individual life choices, and shaping social policy formation.

This article considers distinct ways of understanding the world, referred to in psychology as Functions of Consciousness or as Cognitive Modes, having as the scope of interest epistemology and natural sciences. Inspired by C.G. Jung's Simile of the Spectrum, we consider three basic cognitive modes associated to: (R) embodied instinct, experience, and action; (G) reality perception and learning; and (B) concept abstraction, rational thinking, and language. RGB stand for the primary colors: red, green, and blue. Accordingly, a conceptual map between (...) cognitive modes and primary and secondary colors is built based on the physics and physiology of color perception and epistemological characteristics of the aforementioned cognitive modes, leading to logical relations structured as an Hexagon of Opposition. Finally, this model of cognitive modes is applied to the analysis and interpretation of some important episodes in the historical development of physics and technology. (shrink)

This volume develops a fundamentally different categorical framework for conceptualizing time and reality. The actual taking place of reality is conceived as a “constellatory self-unfolding” characterized by strong self-referentiality and occurring in the primordial form of time, the not yet sequentially structured “time-space of the present.” Concomitantly, both the sequentially ordered aspect of time and the factual aspect of reality appear as emergent phenomena that come into being only after reality has actually taken place. In this new framework, time functions (...) as an ontophainetic [H1] platform, i.e., as the stage on which reality can first occur. Events are merely the “tracks” that the actual taking place of reality leaves behind on the co-emergent “canvas’’ of local spacetime. -/- The view of time proposed here is particularly relevant to the recent debate over the “ER=EPR” conjecture targeting the relation between quantum physics and general relativity theory. The novelty of this radically different framework is that it allows quantum reduction and singularities to be addressed as inverse transitions into and out of the factual layer of reality: In quantum physical state reduction, reality “gains” the chrono-ontological format of facticity, and the sequential aspect of time becomes applicable. In singularities, by contrast, the opposite happens: Reality loses its local spacetime formation and reverts back to its primordial, pre-local shape – making the use of causality relations, Boolean logic and the dichotomization of subject and object obsolete in the process. -/- For our understanding of the relation between quantum and relativistic physics, this new view opens up fundamentally new perspectives: Both are legitimate views of time and reality; they simply address very different chrono-ontological portraits, and thus should not lead us to erroneously prefer one view over the other. -/- The task of the book is to provide a formal framework in which this radically different view of time and reality can be suitably addressed. The mathematical approach is based on the logical and topological features of the Borromean Rings, and draws upon concepts and methods from algebraic and geometric topology – especially the theory of sheaves and links, group theory, logic and information theory in relation to the standard constructions employed in quantum mechanics and general relativity, shedding new light on the problems of their compatibility. The intended audience includes physicists, mathematicians and philosophers with an interest in the conceptual and mathematical foundations of modern physics. (shrink)
