In the real world, there are choices between large, delayed, punctate rewards and small, more immediate rewards as well as choices between patterns and acts. A common element in these situations is the choice between long- and short-term interests. Key issues for future research appear to be how acts are restructured into larger patterns of behavior, and whether, as Rachlin implies, pattern perception is the cause of pattern generation.

On the basis of neuroiinaging studies, Posner & Raichle summarily report that the prefrontal cortex is involved in executive functioning and attention. In contrast to that superficial view, we briefly describe a testable model of the kinds of representations that are stored in prefrontal cortex, which, when activated, are expressed via plans, actions, thematic knowledge, and schemas.

Inferences about spatial, temporal, and other relations are ubiquitous. This article presents a novel model-based theory of such reasoning. The theory depends on 5 principles. The structure of mental models is iconic as far as possible. The logical consequences of relations emerge from models constructed from the meanings of the relations and from knowledge. Individuals tend to construct only a single, typical model. They spontaneously develop their own strategies for relational reasoning. Regardless of strategy, the difficulty of an inference depends (...) on the process of integration of the information from separate premises, the number of entities that have to be integrated to form a model, and the depth of the relation. The article describes computer implementations of the theory and presents experimental results corroborating its main principle. (shrink)

Research reported by Posner & Raichle may be usefully applied to the rehabilitation of persons with brain damage. Their findings are related to the “dual premotorsystems hypothesis” that reciprocally interactive medial and lateral brain systems are involved in attention and learning. Recent studies show that “brain healing” occurs through dynamic reorganization involving attentional networks postulated by Posner & Raichle.

Images of mindis an exciting book, well-written and wellorganized, but many of the connections the authors draw between PET scan results and more general psychological issues are somewhat strained.

Intersubjectivity refers to the variety of possible relations between perspectives. It is indispensable for understanding human social behaviour. While theoretical work on intersubjectivity is relatively sophisticated, methodological approaches to studying intersubjectivity lag behind. Most methodologies assume that individuals are the unit of analysis. In order to research intersubjectivity, however, methodologies are needed that take relationships as the unit of analysis. The first aim of this article is to review existing methodologies for studying intersubjectivity. Four methodological approaches are reviewed: comparative self-report, (...) observing behaviour, analysing talk and ethnographic engagement. The second aim of the article is to introduce and contribute to the development of a dialogical method of analysis. The dialogical approach enables the study of intersubjectivity at different levels, as both implicit and explicit, and both within and between individuals and groups. The article concludes with suggestions for using the proposed method for researching intersubjectivity both within individuals and between individuals and groups. (shrink)

There have been many readings of Mead's work, and this paper proposes yet another: Mead, theorist of the social act. It is argued that Mead's core theory of the social act has been neglected, and that without this theory, the concept of taking the attitude of the other is inexplicable and the contemporary relevance of the concept of the significant symbol is obfuscated. The paper traces the development of the social act out of Dewey's theory of the act. According to (...) Mead, Dewey's theory does not sufficiently account for consciousness. Grappling with this problematic leads Mead to several key ideas, which culminate in his theory of the social act. The social act and taking the attitude of the other are then illustrated by the analysis of a game of football. The interpretation presented has two novel aspects: first, symbolisation arises not simply through self taking the attitude of the other, but through the pairing of this attitude with the complementary attitude in self; second, self is able to take the attitude of the other to the extent that self has in actuality or in imagination previously been in the social position of the other. From this standpoint the key issue is how the attitude of self and other become integrated. New directions for empirical research, aimed at advancing this question are outlined. Finally, the paper shows how the social act can contribute to our contemporary concerns about the nature of the symbolic. (shrink)

Aeschylus' account of the sacrifice of Iphigeneia in the Agamemnon has elicited an extraordinarily wide range of interpretations–a critical response which, in its veryproductivity, may signal a central aspect of the description itself. While more recent explications have been profitably informed by research in cult and ritual, there remains, I would like to suggest, an important literary possibility which merits consideration, particularly in a text where so much has been shaped from a close and profound engagement with the Homeric tradition. (...) The description of the sacrifice is forcefully carried by enjambement from one stanza into another by the sheer weight, as it were, of the force that crushingly silences, βίαι χαλινν τ᾿ άναύδωι μνει . In the midst of much that is dark and difficult to construe, the composition yields a sudden effusion of colour, a striking trail of saffron. The sense of concealment, of a figure enveloped or enshrouded, which has been suggested by the phrase πέπλοισι περιπετή , opens on to an image of unfolding, the falling spread of a robe caught in itsflow towards the ground, κρόκου βαφάς δ ς πέδονχέουσα.

Depersonalization and derealization refer to states of dissociation in which one feels a sense of alienation in relation to one’s self and environment, respectively. Whilst transient episodes often diminish without treatment, chronic experiences of DP and DR may last for years, with common treatments lacking a strong evidence base for their efficacy. We propose a theoretical explanation of DP and DR based on interoceptive predictive coding, and discuss how transient experiences of DP and DR may be induced in the non-clinical (...) population using virtual reality. Further, we review the use of heartbeat evoked potentials in detecting the neural correlates of DP and DR allowing for an objective measure of these experiences in the non-clinical population. Finally, we discuss how the induction and detection of transient experiences of DP and DR in the non-clinical population could shed light on how the brain constructs one’s sense of self and reality.

A common objection to representationalism is that a representationalist view of phenomenal character cannot accommodate the effects that shifts in covert attention have on visual phenomenology: covert attention can make items more visually prominent than they would otherwise be without altering the content of visual experience. Recent empirical work on attention casts doubt on previous attempts to advance this type of objection to representationalism and it also points the way to an alternative development of the objection.

ABSTRACTEpisodic memory is the ability to revisit events in one's personal past, to relive them as if one travelled back in mental time. It has widely been assumed that such an ability imposes a metaphysical requirement on selves. Buddhist philosophers, however, deny the requirement and therefore seek to provide accounts of episodic memory that are metaphysically parsimonious. The idea that the memory perspective is a centred field of experience whose phenomenal constituents are simulacra of an earlier field of experience, yet (...) attended to in a way that presents them as happening again, is, I suggest, a better one than that the memory perspective consists in taking as object-aspect the subject-aspect of the earlier experience, or the idea that it consists in labelling a representation of the earlier experience with an I-tag.

Abstract: The notion of a self-pattern, as developed in the pattern theory of self, which holds that the self is best explained in terms of the kind of reality that pertains to a dynamical pattern, acknowledges the importance of neural dynamics, but also expands the account of self to extra-neural (embodied and enactive) dynamics. The pattern theory of self, however, has been criticized for failing to explicate the dynamical relations among elements of the self-pattern; as such, it seems to be (...) nothing more than a mere list of elements. We’ll argue that the dynamics of a self-pattern are reflected in three significant and interrelated ways that allow for investigation. First, a self-pattern is reflectively reiterated in its narrative component. Second, studies of psychiatric or neurological disorders can help us understand the precise nature of the dynamical relations in a self-pattern, and how they can fail. Third, referencing predictive processing accounts, neuroscience can also help to explicate the dynamical relations that constitute the self-pattern. (shrink)

Questions about the nature of self and self-consciousness are closely aligned with questions about the nature of autonomy. These concepts have deep roots in traditional philosophical discussions that concern metaphysics, epistemology and ethics. They also have direct relevance to practical considerations about informed consent in medical contexts. In this paper, with reference to understanding specific side effects of deep brain stimulation treatment in cases of, for example, Parkinson’s Disease, Obsessive Compulsive Disorder, and Major Depressive Disorder, I’ll argue that it is (...) best to frame discussions of informed consent in terms of relational autonomy and a pattern theory of self.

This paper is a critical analysis and overview of body image conceptualization and its scope and limits within the field of eating disorders up to the present day. In addition, a concept ofemotional bodily experienceis advanced in an attempt to shift towards a more comprehensive and multidimensional perspective for thelived bodyof these patients. It mainly considers contributions from phenomenology, embodiment theories and a review of the empirical findings that shed light on the emotional bodily experience in eating disorders. It proposes (...) an ‘embodied defense’ that leads patients to experiencing their own bodies as objects. This proposal highlights the need for new psychotherapeutic tools in the treatment ofeds that take into account the bodily resonance of emotions and their use for improving adaptive responses to the environment: it calls for helping patients to recover the subjective experience of their bodies.

The approach adopted by Posner & Raichle in this book, with its strong emphasis on the cognitive level of description, is ideally suited to the study of psychotic illnesses. However, their discussion of depression and schizophrenia is based on a very small number of studies and involves ad hoc arguments derived largely from neuroanatomy. Their conclusions are almost certainly wrong.

Posner & Raichle's book presents methods and data that increase support for mind-brain unity and provide a method for studying and verifying brain dysfunction objectively. Their incorporation into the assessment technology of neuropsychology should accordingly constitute a major advance. In addition, these techniques may help clarify longstanding controversies in cognitive psychology such as whether perception is multimodal or amodal.

Learning in intelligent systems is a result of direct or indirect interaction with the environment. Humans can learn by way of different states of (inter-)action such as the execution or the imagery of an action, but their unique potential to induce brain-related as well as mind-related changes in the motor action system is still being debated. The systematic repetition of different states of action (e.g., execution and imagery in terms of physical and mental practice) and their contribution to the learning (...) of complex motor actions has traditionally been approached by way of performance improvements. More recently, approaches highlighting the role of action representation in the learning of complex motor actions have evolved. In the present perspective paper, we build on brain-related findings and sketch recent research on learning by way of imagery and execution from a hierarchical, perceptual-cognitive approach to the motor action system. These findings provide valuable insights into the learning of intelligent systems from a perceptual-cognitive, representation-based perspective and as such add to our current understanding of action representation in memory and its changes with practice. Future research should build bridges between approaches in order to more thoroughly understand functional changes throughout the learning process, and to jointly contribute to developing intelligent cognitive systems and their application in robotics, rehabilitation, or sports.

Rachlin's attack on the internal commitment model rests on the demonstrably false claim that self-punishment does not exist. He is correct that habits are an effective device for solving self-control problems, but his additional claim that they are the only such device makes it hard to explain how good habits develop in the first place. Someone with a self-control problem would always choose the spuriously attractive reward, which, over time, would create bad habits.

Encoding articulate speech is widely accepted as the principal (or sole) role of the frontal operculum. Clinical observations of speech apraxia have been confirmed by brain-imaging studies of speech production. We present evidence that the frontal operculum also programs limb movements. We argue that this area is a ventral counterpart of the dorsal premotor area. The two are functionally distinguished by specialization for somatic and visual space, respectively.

Heyman's two crucial theses are that people over-value immediate rewards, and that addictive substances “subvert the value of competing commodities.” These perennial ideas were discussed by Plato. Whereas Heyman provides scientific clarification and support for the first, the second remains problematic. I outline how this deficiency might be remedied via evolutionary considerations.

I concur with Merker and colleague's critiques, suggesting that hypotheses about the evolutionary function of consciousness can help address them. Brains are parallel systems that function to compute possible actions and predict outcomes. I hypothesize that a core function of consciousness per se is the global feedback of information about those actions actually executed, supporting local learning via neuronal updating.

We define aesthetic emotions as emotions that underlie the evaluative assessment of artworks. They are separated from the wider class of art-elicited emotions. Aesthetic emotions historically have been characterized as calm, as lacking specific patterns of embodiment, and as being a sui generis kind of pleasure. We reject those views and argue that there is a plurality of aesthetic emotions contributing to praise. After presenting a general account of the nature of emotions, we analyze twelve positive aesthetic emotions in four (...) different categories: emotions of pleasure, contemplation, amazement, and respect. The emotions that we identify in each category, including feelings of fluency, intrigue, wonder, and adoration, have been widely neglected both within aesthetics and in emotion research more broadly.

Many now consider “instinct” and “learning” opposite poles of a unidimensional continuum. An alternative model with two independently varying parameters predicts different selective pressures. Behavioral adaptation matches the organism's utilizations of stimuli and responses to their ecological validities: the mean validity over evolutionary time specifies the optimal initial potency of the prepared association; the variance specifies the optimal prepared plasticity.

A methodological problem may distort the implications derived from the metabolism scans of the brain, but Posner & Raichle may have found neural networks which underlie the analytical and synthetical hemispheric data processing mechanism. This methodological problem is that a large regional consumption of energy, detected by the PET technique, is not necessarily related to more data processing. It may be related to the inefficiency of the neural system at this region.

In this paper we contrast bounded and ecological rationality with a proposed alternative, generative rationality. Ecological approaches to rationality build on the idea of humans as “intuitive statisticians” while we argue for a more generative conception of humans as “probing organisms.” We first highlight how ecological rationality’s focus on cues and statistics is problematic for two reasons: the problem of cue salience, and the problem of cue uncertainty. We highlight these problems by revisiting the statistical and cue-based logic that underlies (...) ecological rationality, which originate from the misapplication of concepts in psychophysics. We then work through the most popular experimental task in the ecological rationality literature—the city size task—to illustrate how psychophysical assumptions have informally been linked to ecological rationality. After highlighting these problems, we contrast ecological rationality with a proposed alternative, generative rationality. Generative rationality builds on biology—in contrast to ecological rationality’s focus on statistics. We argue that in uncertain environments cues are rarely given or available for statistical processing. Therefore we focus on the psychogenesis of awareness rather than psychophysics of cues. For any agent or organism, environments “teem” with indefinite cues, meanings and potential objects, the salience or relevance of which is scarcely obvious based on their statistical or physical properties. We focus on organism-specificity and the organism-directed probing that shapes awareness and perception. Cues in teeming environments are noticed when they serve as cues-for-something, requiring what might be called a “cue-to-clue” transformation. In this sense, awareness toward a cue or cues is actively “grown.” We thus argue that perception might more productively be seen as the presentation of cues and objects rather than their representation. This generative approach not only applies to relatively mundane organism interactions with their environments—as well as organism-object relationships and their embodied nature—but also has significant implications for understanding the emergence of novelty in economic settings. We conclude with a discussion of how our arguments link with—but modify—Herbert Simon’s popular “scissors” metaphor, as it applies to bounded rationality and its implications for decision making in uncertain, teeming environments.

There may be evolutionary as well as economic reasons why organisms generally act impulsively. I discuss this possibility and suggest some follow-up experiments that may clarify the exciting empirical and theoretical contributions made by the experiments discussed in the target article.

Heyman's target article makes a strong case for a behavioral approach to addiction, yet some important assumptions require justification, and promising behavioral alternatives to the author's melioration approach should be considered. In particular, the behavioral economic approach to addiction appears well developed and comprehensive. How does the melioration approach complement or improve on a behavioral economic account?

Behavioral research suggests that rule-governed behavior should be less sensitive to environmental changes and thus more resistant to extinction (disconfirmation) than contingency-governed behavior. The opposite is implied in Davey's discussion of ontogenetic and phylogenetic contributions to fear development. The generality of the behavioral findings and their apparent inconsistency with the present article should be further explored with more sensitive research paradigms.

Although most aspects of world and self-consciousness are inherently subjective, neuroscience studies in humans and non-human animals provide correlational and causative indices of specific links between brain activity and representation of the self and the world. In this article we review neuroanatomic, neurophysiological and neuropsychological data supporting the hypothesis that different levels of self and world representation in vertebrates rely upon i) a 'basal' subcortical system that includes brainstem, hypothalamus and central thalamic nuclei and that may underpin the primary (or (...) anoetic) consciousness likely present in all vertebrates; and ii) a forebrain system that include the medial and lateral structures of the cerebral hemispheres and may sustain the most sophisticated forms of consciousness (e.g. noetic (knowledge based) and autonoetic, reflective knowledge). We posit a mutual, bidirectional functional influence between these two major brain circuits. We conclude that basic aspects of consciousness like primary self and core self (based on anoetic and noetic consciousness) are present in many species of vertebrates and that, even self-consciousness (autonoetic consciousness) does not seem to be a prerogative of humans and of some non-human primates but may, to a certain extent, be present in some other mammals and birds.
