The effects of lexical context on phonological processing are pervasive and there have been indications that such effects may be modulated by attention. However, attentional modulation in speech processing is neither well documented nor well understood. Experiment 1 demonstrated attentional modulation of lexical facilitation of speech sound recognition when task and critical stimuli were identical across attention conditions. We propose modulation of lexical activation as a neurophysiologically plausible computational mechanism that can account for this type of modulation. Contrary to the (...) claims of critics, this mechanism can account for attentional modulation without violating the principle of interactive processing. Simulations of the interactive TRACE model extended to include two different ways of modulating lexical activation showed that each can account for attentional modulation of lexical feedback effects. Experiment 2 tested conflicting predictions from the two implementations and provided evidence that is consistent with bias input as the mechanism of attentional control of lexical activation.

Although previous work has linked parent autonomy support to the development of children’s executive function skills, the role of specific autonomy-supportive behaviors has not been thoroughly investigated. We compiled data from four preschool-age samples in the Midwestern United States to examine three relevant autonomy-supportive behaviors and their associations with child EF. We coded parent autonomy-supportive behaviors from a 10-min interaction between parent and child dyads working on challenging jigsaw puzzles together. Children completed a battery of EF. Overall, child EF was (...) most consistently correlated with the offering choice subscale. Additionally, only the offering choice subscale predicted child EF while controlling for the other autonomy support subscales and child age. These results suggest that parent provision of choice is an especially relevant aspect of autonomy-supportive parenting and may be important to the development of EF in early childhood. Future research should directly measure children’s experience with choice and how it relates to emerging EF. (shrink)

This piece, included in the drift special issue of continent. , was created as one step in a thread of inquiry. While each of the contributions to drift stand on their own, the project was an attempt to follow a line of theoretical inquiry as it passed through time and the postal service(s) from October 2012 until May 2013. This issue hosts two threads: between space & place and between intention & attention . The editors recommend that to experience the (...) drifiting thought that attention be paid to the contributions as they entered into conversation one after another. This particular piece is from the BETWEEN SPACE & PLACE thread: April Vannini, Those Between the Common * Laura Dean & Jesse McClelland, Ballard: A Portrait of Placemaking * Amara Hark Weber, Crossroad * Isaac Linder & Berit Soli-Holt, The Call of the Wild: Terro(i)r Modulations * Ashley D. Hairston, Momma taught us to keep a clean house * Sean Smith, The Garage (Take One) * * * * Ballard: A Portrait of Placemaking from continent. on Vimeo . How do people perceive changing landscapes and lifestyles in our neighborhood? We were drawn to this question, perhaps like our interviewees, because we are interested in a certain mystique in Ballard, because we enact something important about it when we go to its coffee shops and restaurants, and because we are transients from other places. Furthermore, we are not always sure of our place in the city, or how our points of reference here may be changing. Much can be said about Seattle’s role in white settlement and in its original industries: shipping, canning, and logging. Much can be said about the arrival of Scandinavian laborers in Ballard, or how the town of Ballard came to be incorporated into Seattle. But as in maps, while these accounts may ground key details, they do not encompass our imaginations of place. Over the last few decades, new meanings in Ballard have been drawn from the built environment. An old railroad track, since converted into a bike path, allows close-up views of storage lots, dry docks and shipyards still lining the ferryway at Ballard’s south edge. Hardware stores and auto repair shops remain clustered along an early bridge and what used to be the city’s first major highway. Nearby, along Market Street and Ballard Avenue, a parallel world of leisure has sprung up celebrating craft processes of work. This is a world of artisan beer, gluten-free pizza, organic coffee, vintage clothing, designer furniture, and one of the city’s finest year-round farmer’s markets. In the past, a noodle shop, a tapas bar, and a Mexican food cart might all have been out of place, but today, they all hang in the balance. As a widening array of consumer spaces channels urban trajectories into the future, contemporary landscapes and lifestyles are retrofitted to traces of the past. The functional and aesthetic components of cities are affected by scales far outside the neighborhood. But as Ballard’s rapidly changing housing market attests, people resituate themselves and the places around them by winnowing out distances and connections between self and other. Condo owners, young couples, single adults, students, senior citizens, and the homeless scramble, revise and recompile landscapes in dynamic and uneven ways. Often, these shifts are an open secret in which past and future are sutured together — debated, digested, and dreamed over. (shrink)

The inequitable distribution of domestic and caring labour in different-sex couples has been a longstanding feminist concern. Some have hoped that having both partners at home during the COVID-19 pandemic would usher in a new era of equitable work and caring distributions. Contrary to these hopes, old patterns seem to have persisted. Moreover, studies suggest this inequitable distribution often goes unnoticed by the male partner. This raises two questions. Why do women continue to shoulder a disproportionate amount of housework and (...) childcare despite economic and cultural gains? And why is there a widespread one-sided misrepresentation within different-sex couples about how domestic and caring work is distributed between the two partners? We answer these questions by appealing to affordance perception – the perception of possibilities for action in one's environment. We propose an important gender disparity in the perception of affordances for domestic tasks such as the dishwasher affording emptying, the floor affording sweeping and a mess affording tidying. We argue that this contributes not only to the inequitable distribution of domestic labour but to the frequent invisibility of that labour. We explore the consequences of this hypothesis for resistance and social change. (shrink)

Conservatives claim that all phenomenal properties are sensory. Liberals countenance non-sensory phenomenal properties such as what it’s like to perceive some high-level property, and what it’s like to think that p. A hallmark of phenomenal properties is that they present an explanatory gap, so to resolve the dispute we should consider whether experience has non-sensory properties that appear ‘gappy’. The classic tests for ‘gappiness’ are the invertibility test and the zombifiability test. I suggest that these tests yield conflicting results: non-sensory (...) properties lend themselves to zombie scenarios but not to inversion scenarios. Which test should we trust? Against Carruthers & Veillet (2011), I argue that invertibility is not a viable condition of phenomenality. In contrast, being zombifiable is credibly necessary and sufficient for phenomenality. I conclude that there are non-sensory properties of experience that are ‘gappy’ in the right way, and that liberalism is therefore the most plausible position. (shrink)

In a seminal 1977 article, Rumelhart argued that perception required the simultaneous use of multiple sources of information, allowing perceivers to optimally interpret sensory information at many levels of representation in real time as information arrives. Building on Rumelhart's arguments, we present the Interactive Activation hypothesis—the idea that the mechanism used in perception and comprehension to achieve these feats exploits an interactive activation process implemented through the bidirectional propagation of activation among simple processing units. We then examine the interactive activation (...) model of letter and word perception and the TRACE model of speech perception, as early attempts to explore this hypothesis, and review the experimental evidence relevant to their assumptions and predictions. We consider how well these models address the computational challenge posed by the problem of perception, and we consider how consistent they are with evidence from behavioral experiments. We examine empirical and theoretical controversies surrounding the idea of interactive processing, including a controversy that swirls around the relationship between interactive computation and optimal Bayesian inference. Some of the implementation details of early versions of interactive activation models caused deviation from optimality and from aspects of human performance data. More recent versions of these models, however, overcome these deficiencies. Among these is a model called the multinomial interactive activation model, which explicitly links interactive activation and Bayesian computations. We also review evidence from neurophysiological and neuroimaging studies supporting the view that interactive processing is a characteristic of the perceptual processing machinery in the brain. In sum, we argue that a computational analysis, as well as behavioral and neuroscience evidence, all support the Interactive Activation hypothesis. The evidence suggests that contemporary versions of models based on the idea of interactive activation continue to provide a basis for efforts to achieve a fuller understanding of the process of perception.

Page's proposal to stipulate representations in which individual units correspond to meaningful entities is too unconstrained to support effective theorizing. An approach combining general computational principles with domain-specific assumptions, in which learning is used to discover representations that are effective in solving tasks, provides more insight into why cognitive and neural systems are organized the way they are.

Kriegel’s self-representationalist theory of phenomenal consciousness pursues two projects. The first is to offer a positive account of how conscious experience arises from physical brain processes. The second is to explain why consciousness misleadingly appears to be irreducible to the physical i.e. to ‘demystify’ consciousness. This paper seeks to determine whether SR succeeds on the second project. Kriegel trades on a distinction between the subjective character and qualitative character of conscious states. Subjective character is the property of being a conscious (...) state at all, while qualitative character determines what it is like to be in that state. Kriegel claims that SR explains why subjective character misleadingly appears irreducible, thereby neutralising the apparent irreducibility of consciousness. I argue that although SR credibly demystifies subjective character, it cannot explain why qualitative character also appears irreducible. I conclude that we should pursue the possibility of a hybrid position that combines SR with an account that does explain the apparent irreducibility of qualitative character. (shrink)

Phenomenal consciousness presents a distinctive explanatory problem. Some regard this problem as ‘hard’, which has troubling implications for the science and metaphysics of consciousness. Some regard it as ‘easy’, which ignores the special explanatory difficulties that consciousness offers. Others are unable to decide between these two uncomfortable positions. All three camps assume that the problem of consciousness is either easy or hard. I argue against this disjunction and suggest that the problem may be ‘tricky’—that is, partly easy and partly hard. (...) This possibility emerges when we recognise that consciousness raises two explanatory questions. The Consciousness Question concerns why a subject is conscious rather than unconscious. The Character Question concerns why a conscious subject’s experience has the phenomenology it has rather than some other. I explore the possibility of one or other of these explanatory challenges being hard and the other easy, and consider the dialectical ramifications this has for all sides of the debate. (shrink)

This paper explores the idea that popular narrative film can somehow contribute to our philosophical understanding. I identify a number of problems with this 'film as philosophy' thesis and argue that the capacity of film to contribute to philosophy is not as great as many authors think. Specifically, I argue that film can only offer genuinely distinctive insights into philosophical questions *about film* and explore Hitchcock's Rear Window as an example of this.

The commentaries reflect three core themes that pertain not just to our theory, but to the enterprise of connectionist modeling more generally. The first concerns the relationship between a cognitive theory and an implemented computer model. Specifically, how does one determine, when a model departs from the theory it exemplifies, whether the departure is a useful simplification or a critical flaw? We argue that the answer to this question depends partially upon the model's intended function, and we suggest that connectionist (...) models have important functions beyond the commonly accepted goals of fitting data and making predictions. The second theme concerns perceived in-principle limitations of the connectionist approach to cognition, and the specific concerns these perceived limitations raise for our theory. We argue that the approach is not in fact limited in the ways our critics suggest. One common misconception, that connectionist models cannot address abstract or relational structure, is corrected through new simulations showing directly that such structure can be captured. The third theme concerns the relationship between parallel distributed processing (PDP) models and structured probabilistic approaches. In this case we argue that there the difference between the approaches is not merely one of levels. Our PDP approach differs from structured statistical approaches at all of Marr's levels, including the characterization of the goals of cognitive computations, and of the representations and algorithms used.

Chalmers (2018) considers a wide range of possible responses to the meta-problem of consciousness. Among them is the ignorance hypothesis -- the view that there only appears to be a hard problem because of our inadequate conception of the physical. Although Chalmers quickly dismisses this view, I argue that it has much greater promise than he recognizes. The plausibility of the ignorance hypothesis depends on how exactly one frames the 'problem intuitions' that a solution to the meta-problem must explain. I (...) argue that problem intuitions are hybrid intuitions that encompass one's intuitive take on the phenomenal and one's intuitive take on the physical. The ignorance hypothesis undermines the second half of these hybrid intuitions. I show how the ignorance hypothesis is preferable to the alternatives and attempt to explain why there is such widespread resistance to this promising position. (shrink)

This paper attempts a sympathetic comparison between John Dewey and Richard Rorty. In particular I establish the ways in which both Dewey's and Rorty's aesthetical modes require qualitative starting points (or some indeterminate-event trajectory) as a condition for any poetic/novel movement into the future. I show how Dewey's notions of "indeterminate situation," highlighted in his event-metaphysics, resonates with Rorty's notion of metaphor, and that finally Rorty does in fact (wittingly or not) harbor a place for the noncognitive and nonlinguistic via, (...) interestingly enough, a linguistic device. How Rorty uses his notion of metaphor (inspired by Donald Davidson's groundbreaking work) starts very much to take on the feel of what Dewey meant by "primary experience." My emphasis, then, falls on the necessity to both of their respective pragmatic positions of a qualitative starting point (QSP). In this way, the troubling dualism that has developed between experience and language starts to dissolve. (shrink)

To what extent can film - or individual films - act as a vehicle of or forum for philosophy itself?. Many have responded that films can indeed do philosophy to a substantial degree. Furthermore, it has been claimed that this virtue does not belong solely to ‘art’ films, but that popular cinema too can do philosophy. A case in point is Spike Jonze’s 1999 film Being John Malkovich, the Oscar-winning screenplay of which was written by Charlie Kaufman. The outrageous premise (...) of this comic fantasy is summarised by the film’s protagonist, Craig Schwartz: "There's a tiny door in my office Maxine. It's a portal, and it takes you inside John Malkovich. You see the world through John Malkovich's eyes. And then, after about fifteen minutes, you're spit out into a ditch on the side of the New Jersey Turnpike." The philosophical issues that this scenario raises are manifold. My primary aim in this paper is to follow the film through its exploration of subjectivity, clarifying its insights with the aid of current philosophical work on the topic. Hopefully, this will enhance our understanding both of subjectivity, and of the philosophical relevance of the film. A secondary goal of this enquiry is to provide a clear example of film-as-philosophy, perhaps demonstrating how film contributes something to the philosophical forum that an academic text cannot.

Jackson’s formulation of the knowledge argument has had an inestimable influence on the discussion of consciousness and the apparent problem it presents for physicalism. A common objection to KA is the ‘ignorance objection’. According to this objection, our intuitions about Mary merely reflect our ignorance of physical facts that are integral to the explanation of phenomenal consciousness. Armed with the insights of a future science, Mary would actually be able to deduce what it’s like to see red. We only have (...) the intuition that Mary would learn something new because we don’t know what she knows. Those sympathetic to KA have brushed away the ignorance objection on the grounds that evstructuren though we don’t know what the future science of consciousness will reveal, we do know what kind of facts it will contain and know that these are the wrong kind of facts from which to deduce facts about phenomenal consciousness. In other words, they suggest that the insight that underwrites KA is ‘future-proof’: it is not the kind of insight that could be displaced by new scientific knowledge. I argue that this strategy for defending KA is dialectically problematic and reveals a fundamental limitation of the Mary thought experiment. (shrink)

In this article, I argue that an epistemic question about knowledge of our own phenomenal states encourages a certain metaphysical picture of consciousness according to which phenomenal states are reflexive mental representations. Section 1 describes and motivates the thesis that phenomenal self-knowledge is ‘receptive’: that is, the view that a subject has knowledge of their phenomenal states only insofar as they are inwardly affected by those states. In Sections 2 and 3, I argue that this model of phenomenal self-knowledge is (...) unable to accommodate knowledge of our own phenomenology or knowledge of our own awareness. In Section 4, I seek a non-receptive model of phenomenal self-knowledge. I argue that Kriegel’s Self-Representationalist theory of consciousness is uniquely equipped to show how phenomenal self-knowledge is possible. (shrink)

We share with Anderson & Lebiere (A&L) (and with Newell before them) the goal of developing a domain-general framework for modeling cognition, and we take seriously the issue of evaluation criteria. We advocate a more focused approach than the one reflected in Newell's criteria, based on analysis of failures as well as successes of models brought into close contact with experimental data. A&L attribute the shortcomings of our parallel-distributed processing framework to a failure to acknowledge a symbolic level of thought. (...) Our framework does acknowledge a symbolic level, contrary to their claim. What we deny is that the symbolic level is the level at which the principles of cognitive processing should be formulated. Models cast at a symbolic level are sometimes useful as high-level approximations of the underlying mechanisms of thought. The adequacy of this approximation will continue to increase as symbolic modelers continue to incorporate principles of parallel distributed processing. (shrink)

Quentin Smith has argued that it is logically impossible for there to be a divine cause of the universe. His argument is based on a Humean analysis of causation (confined to event causation, specifically excluding any consideration of agency) and a principle drawn from that analysis that he takes to be a logical requirement for every possibly valid theory of causation. He also thinks that all divine volitions are efficacious of logical necessity. We argue that all of these claims are (...) faulty, and that theists can resist Smith’s arguments without merely begging the question in favor of a divine cause. (shrink)

This thesis introduces the Problem of Consciousness as an antinomy between Physicalism and Primitivism about the phenomenal. I argue that Primitivism is implausible, but is supported by two conceptual gaps. The ‘–tivity gap’ holds that physical states are objective and phenomenal states are subjective, and that there is no entailment from the objective to the subjective. The ‘–trinsicality gap’ holds that physical properties are extrinsic and phenomenal qualities are intrinsic, and that there is no entailment from the extrinsic to the (...) intrinsic. Stoljar’s Epistemic View (EV) suggests that we have a limited conception of the physical world, and that the apparent inexplicability of consciousness is merely a symptom of our ignorance. I argue that EV must satisfy two conditions which require it to specify the content of our ignorance. EV’s best hope is a Russellian appeal to our ignorance of intrinsic physical properties. After arguing in favour of this ignorance claim, I show how it undermines the –trinsicality gap. However, I suggest that the –tivity gap cannot be dealt with by the Russellian ignorance hypothesis, nor by any other version of EV. However, I then argue that the Russellian ignorance hypothesis can still be deployed as half of a hybrid account of the phenomenal. Representationalist theories of consciousness have difficulty with the –trinsicality gap, but show promise with the –tivity gap. Specifically, Kriegel’s Self-Representationalism indicates that there can indeed be an entailment from objective physical states to subjective phenomenal states. This paves the way for my hybrid account of consciousness: the subjectivity of a phenomenal state is the product of its self-representational structure, and the qualitative character of a phenomenal state is the product of the epistemically inaccessible intrinsic physical properties involved in its implementation.

Niels H. Gregersen seeks to illuminate the nature of continuing divine action in the world and to show that the classical theistic doctrine of continuous creation is consonant with some recent scientific theories of self‐productive (“autopoietic”) systems. Central to these theories is the concept of co‐operation; central to Gregersen's theological appropriation of these theories is also the notion of structuring causality developed by philosopher Fred Dretske. While supportive of Gregersen's overall aims and emphases, we find significant disanalogies between co‐operation as (...) a theological construct and as an evolutionary strategy. We also doubt the utility of Dretske's notion for his project. (shrink)

This study develops a concept of “justificatory respect” and applies it to a recent theistic response to contemporary presentations ofatheism and agnosticism. The related concepts of reflexive justificatory respect (applying to one’s own positions) and of an associated epistemic virtue as necessary but not sufficient conditions for theists and unbelievers to engage one another in successful dialogical inquiry are also developed. Novak’s book signally fails to exercise both kinds of respect. His failures serve to partially delineate the condition for success (...) in the project he desiderates. They also highlight the special qualifications of agnostics for engaging in that project. (shrink)

ABSTRACT This study examined how lifestyle factors and gender affect kidney allocation to transplant patients by 99 British and Singaporean participants. Thirty hypothetical patients were generated from a combination of six factors and randomly paired four times. Participants saw 60 patient pairings and, in each pair, chose which patient would receive treatment priority. A Bradley-Terry model was used to derive coefficients for each factor per participant. A mean factor score was then calculated across all participants for each factor. Participants gave (...) lower priority to patients who drank more, were overweight, smoked more and exercised less. A patient’s diet and gender had no significant effect on allocation. There were no significant cross-cultural differences. There were moderate correlations between participants’ self-reported pre- and post-experiment ordering of decision criteria, and these measures and factor coefficients, suggesting a modest level of decision-making consistency. Between participants, moderate levels of concordance with respect to factor importance were observed for self-reported orderings of factors, and weaker agreement for model-derived coefficients. Very similar results were obtained for both British and Singaporean participants, and the implications of the findings are discussed. (shrink)

Review of Uriah Kriegel's 'The Varieties of Consciousness'.

Review of Uriah Kriegel's The Varieties of Consciousness.

The question of when and how bottom‐up input is integrated with top‐down knowledge has been debated extensively within cognition and perception, and particularly within language processing. A long running debate about the architecture of the spoken‐word recognition system has centered on the locus of lexical effects on phonemic processing: does lexical knowledge influence phoneme perception through feedback, or post‐perceptually in a purely feedforward system? Elman and McClelland (1988) reported that lexically restored ambiguous phonemes influenced the perception of the following (...) phoneme, supporting models with feedback from lexical to phonemic representations. Subsequently, several authors have argued that these results can be fully accounted for by diphone transitional probabilities in a feedforward system (Cairns et al., 1995; Pitt & McQueen, 1998). We report results strongly favoring the original lexical feedback explanation: lexical effects were present even when transitional probability biases were opposite to those of lexical biases.

Rumelhart and McClelland's chapter about learning the past tense created a degree of controversy extraordinary even in the adversarial culture of modern science. It also stimulated a vast amount of research that advanced the understanding of the past tense, inflectional morphology in English and other languages, the nature of linguistic representations, relations between language and other phenomena such as reading and object recognition, the properties of artificial neural networks, and other topics. We examine the impact of the Rumelhart and (...) McClelland model with the benefit of 25 years of hindsight. It is not clear who “won” the debate. It is clear, however, that the core ideas that the model instantiated have been assimilated into many areas in the study of language, changing the focus of research from abstract characterizations of linguistic competence to an emphasis on the role of the statistical structure of language in acquisition and processing.

To understand Self-Representationalism you need to understand its family. Self-Representationalism is a branch of the Meta-Representationalist family, and according to theories in this family what distinguishes conscious mental representations from unconscious mental representations is that conscious ones are themselves the target of a mental meta¬-representational state. A mental state M1 is thus phenomenally conscious in virtue of being suitably represented by some mental state M2. What distinguishes the Self-Representationalist branch of the family is the claim that M1 and M2 must (...) be the same token mental state, so a mental state is phenomenally conscious in virtue of suitably representing itself. This Self-Representationalist branch of the family divides into further branches, giving us specific implementations of the Self-Representationalist approach. But before asking whether we should adopt Self-Representationalism, and in what form, we should reflect on why Meta-Representationalism is an attractive family in the first place. After all, Self-Representationalist theories trade on their family name, claiming to deliver on the promises that drive the Meta-Representationalist approach. The two most important promises of Meta-Representationalism are: a) the promise of capturing the transitivity of consciousness and; b) the promise of rendering consciousness naturalisable.

The most student-friendly short introduction to philosophy of mind available.

The on-going debate over the ‘admissible contents of perceptual experience’ concerns the range of properties that human beings are directly acquainted with in perceptual experience. Regarding vision, it is relatively uncontroversial that the following properties can figure in the contents of visual experience: colour, shape, illumination, spatial relations, motion, and texture. The controversy begins when we ask whether any properties besides these figure in visual experience. We argue that ‘ensemble properties’ should be added to the list of visually admissible properties. (...) Ensemble properties are features that belong to a set of perceptible objects as a whole as opposed to the individuals that constitute that set. They include such features as the mean size of an array of shapes or the average emotional expression of an array of faces. Recent work in vision science has yielded compelling evidence that the visual system routinely encodes such properties. We argue that epistemological considerations provide strong reasons to think that these properties figure in visual experience. Judgements about ensemble properties are immediately warranted by our perceptual experience, and the only plausible way that a perceptual experience could confer this warrant is if it confers awareness of ensemble properties.
