This article examines what is known about the cognitive science of working memory, and brings the findings to bear in evaluating philosophical accounts of central cognitive processes of thinking and reasoning. It is argued that central cognition is sensory based, depending on the activation and deployment of sensory images of various sorts. Contrary to a broad spectrum of philosophical opinion, the central mind does not contain any workspace within which goals, decisions, intentions, or non-sensory judgments can be active.Introduction: philosophers’ commitmentsMost philosophers believe that our so-called “personal-level” propositional attitudes—our personal judgments, beliefs, goals, values, decisions, and intentions—are consciously accessible. Many will also allow, of course, that some of the processing that takes place within our perceptual faculties is inaccessible to us; and many will grant the possibility of unconscious attitudes, as well as processes of inference and decision mak

Works its way through a variety of different accounts of phenomenal consciousness, looking at the strengths and weaknesses of each. At the heart of the chapter is an extended critical examination of first-order representational theories, of the sort espoused by Dretske and Tye, arguing that they are inferior to higher-order representational accounts. Acknowledges as a problem for HOR theories that they might withhold phenomenal consciousness from most other species of animal, but claims that this problem should not be regarded as a serious obstacle to the acceptance of some such theory. Different versions of HOR theory are discussed, and the author’s own account is briefly elaborated and defended.

This paper examines the recent literature on meta-cognitive processes in non-human animals, arguing that in each case the data admit of a simpler, purely first-order, explanation. The topics discussed include the alleged monitoring of states of certainty and uncertainty, knowledge-seeking behavior in conditions of uncertainty, and the capacity to know whether or not the information needed to solve some problem is stored in memory. The first-order explanations advanced all assume that beliefs and desires come in various different strengths, or degrees.

The present response elucidates, elaborates, and defends the main thesis advanced in the target article: namely, that natural-language sentences play a constitutive role in some human thought processes, and that they are responsible for some of the distinctive flexibility of human thinking, serving to integrate the outputs of a variety of conceptual modules. Section R1 clarifies and elaborates this main thesis, responding to a number of objections and misunderstandings. Section R2 considers three contrasting accounts of the mechanism of intermodular integration. Section R3 discusses objections to some of the empirical data supporting my main thesis. Section R4 criticizes some competing theories of the role of language in cognition. And section R5 considers some proposed supplementary cognitive roles that language might play.

Smith et al. present us with a false dichotomy in explaining their uncertainty data: Either the animals' responses are “under the associative control of stimulus cues,” or the animals must be responding “under the metacognitive control of uncertainty cues.” There is a third alternative to consider: one that is genuinely cognitive, neither associative nor stimulus driven, but purely first-order in character. On this alternative the metacognitive reports of humans in these situations reflect states that are interpretative rather than causal in character.

A number of convergent recent findings with adults have been interpreted as evidence of the existence of two distinct systems for mindreading that draw on separate conceptual resources: one that is fast, automatic, and inflexible; and one that is slower, controlled, and flexible. The present article argues that these findings admit of a more parsimonious explanation. This is that there is a single set of concepts made available by a mindreading system that operates automatically where it can, but which frequently needs to function together with domain-specific executive procedures as well as domain-general resources. This view, too, can be described as a two-systems account. But in this case one of the systems encompasses the other, and the conceptual resources available to each are the same.

Various dichotomies have been proposed to characterize the nature and development of human mindreading capacities, especially in light of recent evidence of mindreading in infants aged 7 to 18 months. This article will examine these suggestions, arguing that none is currently supported by the evidence. Rather, the data support a modular account of the domain-specific component of basic mindreading capacities. This core component is present in infants from a very young age and does not alter fundamentally thereafter. What alters with development are the interactions between core mindreading and other systems, including executive systems, and forms of learning that do not require radical conceptual change

This paper examines the recent literature on meta-cognitive processes in non-human animals, arguing that in each case the data admit of a simpler, purely first-order, explanation. The topics discussed include the alleged monitoring of states of certainty and uncertainty, the capacity to know whether or not one has perceived something, and the capacity to know whether or not the information needed to solve some problem is stored in memory. The first-order explanations advanced all assume that beliefs and desires come in various different _strengths_, or _degrees_

Do we think in natural language? Or is language only for communication? Much recent work in philosophy and cognitive science assumes the latter. In contrast, Peter Carruthers argues that much of human conscious thinking is conducted in the medium of natural language sentences. However, this does not commit him to any sort of Whorfian linguistic relativism, and the view is developed within a framework that is broadly nativist and modularist. His study will be essential reading for all those interested in the nature and significance of natural language, whether they come from philosophy, psychology or linguistics

What is the place of language in human cognition? Do we sometimes think in natural language? Or is language for purposes of interpersonal communication only? Although these questions have been much debated in the past, they have almost dropped from sight in recent decades amongst those interested in the cognitive sciences. Language and Thought is intended to persuade such people to think again. It brings together essays by a distinguished interdisciplinary team of philosophers and psychologists, who discuss various ways in which language may be implicated in human cognition. The editors have provided an introduction which lays out the basic terms and history of the debate, and a consolidated bibliography which will provide a valuable reference resource for all those interested in this area. The volume will be of great interest to all researchers and students interested in language and its place in cognition.

Este artículo investiga la coherencia entre la propuesta de una organización modular masiva de la mente y el enfoque de las heurísticas simples. Se discute una serie de potenciales conflictos entre los dos programas, pero finalmente son desestimados. De todos modos, el programa de las heurísticas simples sí termina socavando uno de los muchos argumentos propuestos para apoyar la modularidad masiva, al menos en el modo en que esta última es comprendida por los filósofos. Así que un resultado de la argumentación será forzarnos a reexaminar la mejor manera de caracterizar la noción de modularidad en la ciencia cognitiva, para que la tesis de la modularidad masiva no deba ser abandonada completamente. Lo que está en juego en esta discusión es si existe una noción de "módulo" que esté bien motivada, de modo que tengamos una buena razón para pensar que la mente humana deba ser masivamente modular en su organización. Argumentaré que tal noción existe. This chapter investigates the extent to which claims of massive modular organization of the mind are consistent with the main elements of the simple heuristics research program. A number of potential sources of conflict between the two programs are investigated and defused. However, the simple heuristics program turns out to undermine one of the main arguments offered in support of massive modularity, at least as the latter is generally understood by philosophers. So one result of the argument will be to force us to re-examine the way in which the notion of modularity in cognitive science should best be characterized, if the thesis of massive modularity isn't to be abandoned altogether. What is at stake in this discussion, is whether there is a well-motivated notion of "module" such that we have good reason to think that the human mind must be massively modular in its organization. I shall be arguing that there is

The goal of this article is to display the attractiveness of a novel account of the place of creativity in the human mind. This is designed to supplement (and perhaps replace) the widespread assumption that creativity is thought-based, involving novel combinations of concepts to form creative thoughts, with the creativity of action being parasitic upon prior creative thinking. According to the proposed account, an additional (or perhaps alternative) locus of creativity lies in the assembly and activation of action-schemata, with creative thoughts arising subsequently from the mental rehearsal of those actions, normally resulting in either visual imagery or inner speech

Implicit and explicit attitudes manifest themselves as distinct and partly dissociable behavioral dispositions. It is natural to think that these differences reflect differing underlying representations. The present article argues that this may be a mistake. Although non-verbal and verbal measures of attitudes often dissociate, this may be because the two types of outcome-measure are differentially impacted by other factors, not because they are tapping into distinct kinds of representation or distinct storage systems. I arrive at this view through closer consideration than is usual of the mechanisms and processes that underlie overt behavior.

This chapter defends the positive thesis which constitutes its title. It argues first, that the mind has been shaped by natural selection; and second, that the result of that shaping process is a modular mental architecture. The arguments presented are all broadly empirical in character, drawing on evidence provided by biologists, neuroscientists and psychologists (evolutionary, cognitive, and developmental), as well as by researchers in artificial intelligence. Yet the conclusion is at odds with the manifest image of ourselves provided both by introspection and by common-sense psychology. The chapter concludes by sketching how a modular architecture might be developed to account for the patently unconstrained character of human thought, which has served as an assumption in a number of recent philosophical attacks on mental modularity

This paper argues that navigating insects and spiders possess a degree of mindedness that makes them appropriate (in the sense of “possible”) objects of sympathy and moral concern. For the evidence suggests that many invertebrates possess a belief-desire-planning psychology that is in basic respects similar to our own. The challenge for ethical theory is find some principled way of demonstrating that individual insects do not make moral claims on us, given the widely held belief that some other “higher” animals do make such claims on us.
