Prospective coding in event representation

A perceived event such as a visual stimulus in the external world and a to-be-produced event such as an intentional action are subserved by event representations. Event representations do not only contain information about present states but also about past and future states. Here we focus on the role of representing future states in event perception and generation (i.e., prospective coding). Relevant theoretical issues and paradigms are discussed. We suggest that the predictive power of the motor system may be exploited for prospective coding not only in producing but also in perceiving events. Predicting is more advantageous than simply reacting. Perceptual prediction allows us to select appropriate responses ahead of the realization of an (anticipated) event and therefore, it is indispensable to flexibly and timely adapt to new situations and thus, successfully interact with our physical and social environment.     

Compliance Dynamics Within a Simulated Friendship Network I: The Effects of Agency,Tactic, and Node Centrality

This study investigated the structural causes of perceptions of power and the way that these perceptions create expectations regarding influence attempts. It applied measures derived from dynamic social impact theory to model predictions of target compliance and agent response to an influence attempt. Sociograms provided the structure within which compliance dynamics were investigated. Results from an experiment (N = 458) showed that structural positions with greater eigenvector and betweenness centrality generated stronger perceived power, and that observers' attributions regarding responses to a compliance request follow a systematic three‐step process—agent acts, target responds, and agent reacts. The model, reflecting agency, influence tactic, and power, formalizes the attributional process that observers employ when evaluating compliance requests.     

Predictive coding as a model of cognition

Previous work has shown that predictive coding can provide a detailed explanation of a very wide range of low-level perceptual processes. It is also widely believed that predictive coding can account for high-level, cognitive, abilities. This article provides support for this view by showing that predictive coding can simulate phenomena such as categorisation, the influence of abstract knowledge on perception, recall and reasoning about conceptual knowledge, context-dependent behavioural control, and naive physics. The particular implementation of predictive coding used here (PC/BC-DIM) has previously been used to simulate low-level perceptual behaviour and the neural mechanisms that underlie them. This algorithm thus provides a single framework for modelling both perceptual and cognitive brain function.     

Noise,uncertainty, and interest: Predictive coding and cognitive penetration

This paper concerns how extant theorists of predictive coding conceptualize and explain possible instances of cognitive penetration. Section 1 offers brief clarification of the predictive coding framework and of cognitive penetration. Section 2 develops more precise ways that the predictive coding framework can explain genuine top-down causal effects on perceptual experience. Section 3 develops these insights further with an eye towards tracking one extant criterion for cognitive penetration, namely, that the relevant cognitive effects on perception must be sufficiently direct. In Section 4, we analyze and criticize a claim made by some theorists of predictive coding, namely, that (interesting) instances of cognitive penetration tend to occur in perceptual circumstances involving substantial noise or uncertainty. We argue that, when applied, the claim fails to explain (or perhaps even be consistent with) a large range of important and uncontroversially interesting possible cases of cognitive penetration. We conclude with a general speculation about how the recent work on the predictive mind may influence the current dialectic concerning top-down effects on perception.     

Expert face coding: Configural and component coding of own-race and other-race faces

Configural and holistic coding are hallmarks of face perception. Although recent studies have shown that own-race faces are coded more holistically than other-race faces, the evidence for better configural coding of own-race faces is equivocal. We directly measured configural and component coding of own- and other-race male faces in Caucasian and Chinese participants. We manipulated individual features (components) or their spatial relations (configurations) using a novel morphing method to vary difficulty parametrically and tested sensitivity to these changes in a sequential matching task. Both configural and component coding were better for upright own-race than for upright other-race faces. Inversion impaired detection of configural changes more than it did detection of component changes, but also impaired performance more for easier discriminations,independent of type of change. These results challenge explanations of face expertise that rely solely on configural and holistic processing, and also call into question the widespread interpretation of large inversion decrements as diagnostic of configural coding.     

The development of the SNARC effect: evidence for early verbal coding

In a recent study, Gevers and colleagues (2010, Journal of Experimental Psychology: General, Vol. 139, pp. 180-190) showed that the SNARC (spatial numerical association of response codes) effect in adults results not only from spatial coding of magnitude (e.g., mental number line hypothesis) but also from verbal coding. Because children are surrounded by rulers, number lines, and the like in the classroom, it is intuitively appealing to assume that they first use their mental number line to represent numbers and that only later in development a verbal recoding of magnitude information takes place. However, this hypothesis has never been tested. The goal of the current study was to define the developmental pattern of both accounts (spatial and verbal) in explaining the SNARC effect. To this end, 9- and 11-year-olds were tested in a magnitude comparison task. Surprisingly, clear and robust evidence for verbal coding of magnitude information was observed in both age groups. Our results imply that the ability to use verbal coding of magnitude information is robustly present early in formal schooling.     

Contrasting five different theories of letter position coding: evidence from orthographic similarity effects

Five theories of how letter position is coded are contrasted: position-specific slot-coding, Wickelcoding, open-bigram coding (discrete and continuous), and spatial coding. These theories make different predictions regarding the relative similarity of three different types of pairs of letter strings: substitution neighbors, neighbors-once-removed, and double-substitution neighbors. In Experiment 1, we used an illusory word paradigm and found that neighbor-once-removed similarity contexts resulted in fewer illusory word reports than substitution neighbors but more illusory words than double-substitution neighbors. In Experiments 2 and 3, we used a masked form priming technique with a lexical-decision task. The pattern of facilitation was as predicted by spatial coding but was incompatible with slot-coding, Wickelcoding, and both versions of open-bigram coding. These results provide further support for the SOLAR (self-organizing lexical aquisition and recognition) model of visual word identification.     

Mnemonic strategy instruction in coding, processing, and recall of movement-related cues by mentally retarded children

The purpose of study was to examine the differential coding and processing characteristics of two movement cue types in the investigation of the short-term memory of mentally retarded and nonretarded children. The central focus of the study was to determine the effects of formal instruction in the use of a mnemonic versus no instruction with both types of cues in a memory for movement paradigm. The investigation was conducted across two experiments. The main conclusion drawn from Exp. 1 was that movement 'location' cues were coded, processed, and retained by both the mentally retarded and the nonretarded children, but only the former required instruction in the use of a mnemonic to achieve accurate recall. Exp. 2 was fundamentally a replication of Exp. 1 with the exception that movement 'extent' cues were maintained reliable. The results were similar but not exactly the same as those of Exp. 1. Only the mentally retarded children given mnemonic instruction appeared to code, process, and retain movement 'extent' cues over time. The net result of the two experiments was that formal instruction in the use of a mnemonic was of benefit to the mentally retarded subjects and was not necessary for nonretarded subjects to achieve the same level of movement accuracy.     

Predictive coding: an account of the mirror neuron system

Is it possible to understand the intentions of other people by simply observing their actions? Many believe that this ability is made possible by the brain’s mirror neuron system through its direct link between action and observation. However, precisely how intentions can be inferred through action observation has provoked much debate. Here we suggest that the function of the mirror system can be understood within a predictive coding framework that appeals to the statistical approach known as empirical Bayes. Within this scheme the most likely cause of an observed action can be inferred by minimizing the prediction error at all levels of the cortical hierarchy that are engaged during action observation. This account identifies a precise role for the mirror system in our ability to infer intentions from actions and provides the outline of the underlying computational mechanisms.     

The Existential Sources of Phenomenology: Heidegger on Formal Indication

Abstract: This article contributes to the contemporary debate regarding the young Heidegger's method of formal indication. Theodore Kisiel argues that this method constitutes a radical break with Husserl—a rejection of phenomenological reflection that paves the way to the non‐reflective approach of the Beiträge. Against this view, Steven Crowell argues that formal indication is continuous with Husserlian phenomenology—a refinement of phenomenological reflection that reveals its existential sources. I evaluate this debate and adduce further considerations in favor of Crowell's view. To do so, I analyze the young Heidegger's account of phenomenological communication and argue that it further reflects the continuity that Crowell identifies: as he does with reflection, Heidegger refines Husserl's account of phenomenological communication and sheds light on its existential sources.     

A “Primer” in Conceptual Metaphor for Counselors

Conceptual metaphor provides a potentially powerful counseling framework, generalizable across theoretical orientations. According to the conceptual perspective, metaphor is not merely a matter of language, but is an indispensable dimension of human understanding and experience whereby more abstract ideas (like relationships) are understood in terms of more concrete experiences (like journeys). Consequently, when a couple in counseling says, “we're just spinning our wheels,” they are not only using a common colloquial expression, but also giving information about how they conceptualize their relationship. This article provides a theoretical foundation for use of conceptual metaphor and offers examples of its potential for counseling.     

The Effect of Metaphor on Political Attitudes

An experiment was conducted to investigate the impact of metaphors embedded in news articles involving political figures and events. Seventy-two subjects read four brief articles which varied, according to condition, in the valence of the metaphor. It was hypothesized that subjects reading a positively valenced metaphor, which cast the subject of the comparison in a desirable light, would rate. both the person and the issue mentioned in the news article more favorably than would subjects reading a negative metaphor. This hypothesis was confirmed, but only for more politically sophisticated subjects — those more attentive to political news were significantly more influenced by the experimental manipulation. It is suggested that these individual differences may be explained by a schema-based account of metaphor comprehension.     

The dialectics of infinitism and coherentism: inferential justification versus holism and coherence

This paper formally explores the common ground between mild versions of epistemological coherentism and infinitism; it proposes—and argues for—a hybrid, coherentist–infinitist account of epistemic justification. First, the epistemological regress argument and its relation to the classical taxonomy regarding epistemic justification—of foundationalism, infinitism and coherentism—is reviewed. We then recall recent results proving that an influential argument against infinite regresses of justification, which alleges their incoherence on account of probabilistic inconsistency, cannot be maintained. Furthermore, we prove that the Principle of Inferential Justification has rather unwelcome consequences—formally resembling the Sorites paradox—as soon as it is iterated and combined with a natural Bayesian perspective on probabilistic inferences. We conclude that strong versions of foundationalism and infinitism should be abandoned. Positively, we provide a rough sketch for a graded formal coherence notion, according to which infinite regresses of epistemic justification will often have more than a minimal degree of coherence.     

Technology Games: Using Wittgenstein for Understanding and Evaluating Technology

In the philosophy of technology after the empirical turn, little attention has been paid to language and its relation to technology. In this programmatic and explorative paper, it is proposed to use the later Wittgenstein, not only to pay more attention to language use in philosophy of technology, but also to rethink technology itself—at least technology in its aspect of tool, technology-in-use. This is done by outlining a working account of Wittgenstein’s view of language (as articulated mainly in the Investigations) and by then applying that account to technology—turning around Wittgenstein’s metaphor of the toolbox. Using Wittgenstein’s concepts of language games and form of life and coining the term ‘technology games’, the paper proposes and argues for a use-oriented, holistic, transcendental, social, and historical approach to technology which is empirically but also normatively sensitive, and which takes into account implicit knowledge and know-how. It gives examples of interaction with social robots to support the relevance of this project for understanding and evaluating today’s technologies, makes comparisons with authors in philosophy of technology such as Winner and Ihde, and sketches the contours of a phenomenology and hermeneutics of technology use that may help us to understand but also to gain a more critical relation to specific uses of concrete technologies in everyday contexts. Ultimately, given the holism argued for, it also promises a more critical relation to the games and forms of life technologies are embedded in—to the ways we do things.     

JUMPING TOGETHER: A WAY FROM SOCIOBIOLOGY TO BIO‐SOCIO‐HUMANITIES

Sociobiology is a grand narrative of evolutionary biology on which to build unified knowledge. Consilience is a metaphorical representation of that narrative. I take up the same metaphor but apply it differently. I evoke the image of jumping together, not on solid ground but on the strong, flexible canvas sheet of a trampoline, on which natural sciences, social sciences, and the humanities jump together. This image overlaps with the traditional East Asian way of understanding—that is, the “Heaven‐Earth‐Person Triad.” Using recent insights from cognitive science—metaphor, embodiment, and conceptual blending—I propose the alternative way of “bio‐socio‐humanities” to understand and experience the world.     

Contribution of cognitive abilities to performance and improvement on a substitution coding task

Age-related performance variance on substitution coding tests has been found to account for much of the age-related variance in tests of fluid and other abilities, leading to the conclusion that cognitive decline is due to slowing. Although it is an easy task, which could easily be performed accurately given adequate time, the substitution coding task is not a pure measure of cognitive speed. Evidence from growth curve analyses involving 3,708 volunteers (49-95 years of age) from the Manchester and Newcastle Studies of Cognitive Aging (P. Rabbitt, C. Donlan, N. Bent, L. McInnes, & V. Abson, 1993) indicates that, with practice on this task, improvement is related more to memory than to age, reasoning, vocabulary, or perceptual speed. In other words, faster performances are related primarily to memory. Operational similarities between speeded measures and measures of higher order abilities, which weaken the argument for causal relationships, are discussed.     

Pigeons may not use dual coding in the radial maze analog task

Using a radial maze analog task, T. R. Zentall, J. N. Steirn, and P. Jackson-Smith (1990) found evidence that when a delay was interpolated early in a trial, pigeons coded locations retrospectively, but when the delay was interpolated late in the trial, they coded locations prospectively (support for a dual coding hypothesis). In Experiment 1 of the present study, the authors replicated the original finding of dual coding. In Experiments 2 and 3, they used a 2-alternative test procedure that does not require the assumption that pigeons' choice criterion, which changes over the course of the trial, is the same on delay and control trials. Under these conditions, the pigeons no longer showed evidence for dual coding. Instead, there was some evidence that they showed prospective coding, but a more parsimonious account of the results may be that the delay produced a relatively constant decrement in performance at all points of delay interpolation. The original finding of dual coding by Zentall et al. might have been biased by more impulsive choices early in control trials but not in delay trials and by a more stringent choice criterion late in delay trials.     

Phonological and orthographic coding skills in adult readers

Although less skilled readers are handicapped by their poor phonological skills, this may not be true of their visual and orthographic coding skills. Because of an increasing reliance on visual-orthographic coding with reading experience, the author predicted that there would be smaller differences between skilled and less skilled adult readers on orthographic coding measures than on phonological coding measures. The orthographic and phonological coding measures involved, respectively, judgments of which looks more like a word, filv-fild, and which sounds like a real word, kake-dake? On the orthographic measure, reading groups did not differ in coding speed--although the less skilled readers made more errors, but far fewer than on the phonological coding measure. Differences between reading groups were substantial for both speed and errors on the phonological coding measure. Phonological variables accounted for most of the variance in word recognition, and this was especially true for men. The results suggest that in less skilled adult readers, phonological skills are a primary factor in their reading despite some evidence of visual-orthographic compensation.     

Michael Tooley and the Jolly Nasty Conclusion

Abstract Some recent powerful and persuasive arguments seem to imply that a world of people with lives that are barely worth living is preferable to a world which contains fewer people all of whom have extremely satisfying lives. This ‘repugnant conclusion’ is clearly to be rejected if possible—but is it possible? Many attempts to reject or avoid it have failed. One of the latest, by Michael Tooley, looked promising but the present essay argues that this attempt has also failed.
