Fodor's thinking on modularity has been influential throughout a range of the areas studying cognition, chiefly as a prod for positive work on modularity and domain-specificity. In _The Mind Doesn't Work That Way_, Fodor has developed the dark message of _The Modularity of Mind_ regarding the limits to modularity and computational analyses. This paper offers a critical assessment of Fodor's scepticism with an eye to highlighting some broader issues in play, including the nature of computation and the role of recent (...) empirical developments in the cognitive sciences in assessing Fodor's position.

The social, behavioral, and a good chunk of the biological sciences concern the nature of individual agency, where our paradigm for an individual is a human being. Theories of economic behavior, of mental function and dysfunction, and of ontogenetic development, for example, are theories of how such individuals act, and of what internal and external factors are determinative of that action. Such theories construe individuals in distinctive ways.

This is a joint review of Shirley Strum and Linda Fedigan's Primate Encounters: Models of Science, Gender, and Society (Chicago, 2000) and Sarah Blaffer Hrdy, Mother Nature: A History of Mothers, Infants, and Natural Selection (Pantheon, 1999).

In his Experiments in Ethics, Appiah focuses mostly on the dimension of naturalism as a naturalism of deprivation - naturalism’s apparent robbing us of aspects of the world that we had held dear. The aim of this paper is to remind him of that naturalism has a dimension of plenitude as well - its capacity to enrich our conception of the world as well. With regard to character, we argue that scientific psychology can help provide a conception of character as (...) dynamic, in a way that may preserve many key aspects of eudaimonistic ethics from the situationists’ challenge. With regard to intuition, we address Appiah’s worry that naturalistic explanations of the sources of our intuitions may leave us feeling that those intuitions have been thereby debunked. We suggest that it may be that feeling of debunking that should itself be debunked. (shrink)

In this paper I seek to show how cultural niche construction theory offers the potential to extend the human evolutionary story beyond the Pleistocene, through the Neolithic, towards the kind of very large-scale societies in which we live today. The study of the human past has been compartmentalised, each compartment using different analytical vocabularies, so that their accounts are written in mutually incompatible languages. In recent years social, cognitive and cultural evolutionary theories, building on a growing body of archaeological evidence, (...) have made substantial sense of the social and cultural evolution of the genus Homo. However, specialists in this field of studies have found it difficult to extend their kind of analysis into the Holocene human world. Within southwest Asia the three or four millennia of the Neolithic period at the beginning of the Holocene represents a pivotal point, which saw the transformation of human society in the emergence of the first large-scale, permanent communities, the domestication of plants and animals, and the establishment of effective farming economies. Following the Neolithic, the pace of human social, economic and cultural evolution continued to increase. By 5000 years ago, in parts of southwest Asia and northeast Africa there were very large-scale urban societies, and the first large-scale states. An extension of cultural niche construction theory enables us to extend the evolutionary narrative of the Pleistocene into the Holocene, opening the way to developing a single, long-term, evolutionary account of human history.

an exemplar of an approach that takes the human mind to be largely the product of social and cultural factors with negligible contributions from biology. The author argues that on the contrary, his sociological theory of the categories is compatible with the possibility of innate cognitive capacities, taking causal cognition as his example. Whether and to what extent there are such innate capacities is a question for research in the cognitive neurosciences. The extent to which these innate capacities can then (...) be explained by natural selection remains an open question for empirical investigation. Key Words: categories • causality • cognition • Durkheim • evolutionary psychology. (shrink)

The various aesthetic phenomena found repeatedly in the scientific enterprise stem from the role of God as artist. If the Creator is an artist, how and why natural scientists study the divine art work can be understood using theological aesthetics and the philosophy of art. The aesthetic phenomena considered here are as follows. First, science reveals beauty and the sublime in natural phenomena. Second, science discovers beauty and the sublime in the theories that are developed to explain natural phenomena. Third, (...) the search for beauty often guides scientists in their work. Fourth, where beauty is perceived, feelings of the sublime often also follow upon further contemplation. This linkage of beauty in science with truth and the sublime runs counter to most aesthetic theory since Kant. Scholarship in theological aesthetics has recently argued that the modern and postmodern elevation of the sublime over beauty is merely a preference that reveals a bias against transcendence—against God. If doing and understanding science can show this sundering of the sublime from the beautiful to be in error, science also gives evidence of transcendence. (shrink)

The dominant assumption about the causal architecture of the mind is, that it is composed of a stable set of components that contribute independently to relevant observables that are employed to measure cognitive activity. This view has been called component-dominant dynamics. An alternative has been proposed, according to which the different components are not independent, but fundamentally interdependent, and are not stable basic properties of the mind, but rather an emergent feature of the mind given a particular task context. This (...) view has been called interaction-dominant dynamics. In this paper, we review evidence for interaction-dominant dynamics as the causal architecture of the mind. We point out, that such an architecture is consistent with problems of convergence in research on the level of results and theorizing. Moreover, we point out that if interaction-dominant dynamics as the causal architecture of the mind were to be true, this would naturally lead to problems with generalization and replicability in sciences of the mind and brain, and would probably warrant changes in the scientific practice with regard to study-design and data analysis.

I argue that John Searle's (1980) influential Chinese room argument (CRA) against computationalism and strong AI survives existing objections, including Block's (1998) internalized systems reply, Fodor's (1991b) deviant causal chain reply, and Hauser's (1997) unconscious content reply. However, a new ``essentialist'' reply I construct shows that the CRA as presented by Searle is an unsound argument that relies on a question-begging appeal to intuition. My diagnosis of the CRA relies on an interpretation of computationalism as a scientific theory about the (...) essential nature of intentional content; such theories often yield non-intuitive results in non-standard cases, and so cannot be judged by such intuitions. However, I further argue that the CRA can be transformed into a potentially valid argument against computationalism simply by reinterpreting it as an indeterminacy argument that shows that computationalism cannot explain the ordinary distinction between semantic content and sheer syntactic manipulation, and thus cannot be an adequate account of content. This conclusion admittedly rests on the arguable but plausible assumption that thought content is interestingly determinate. I conclude that the viability of computationalism and strong AI depends on their addressing the indeterminacy objection, but that it is currently unclear how this objection can be successfully addressed.

According to the evolutionary sceptic, the fact that our cognitive faculties evolved radically undermines their reliability. A number of evolutionary epistemologists have sought to refute this kind of scepticism. This paper accepts the success of these attempts, yet argues that refuting the evolutionary sceptic is not enough to put any particular domain of beliefs – notably scientific beliefs, which include belief in Darwinian evolution – on a firm footing. The paper thus sets out to contribute to this positive justificatory project, (...) underdeveloped in the literature. In contrast to a ‘wholesale’ approach, attempting to secure justification for all of our beliefs on the grounds that our belief-forming mechanisms evolved to track truth, we propose a ‘piecemeal’ approach of assessing the reliability of particular belief-forming mechanisms in particular domains. This stands in contrast to the more familiar attempt to transfer warrant obtained for one domain to another by showing how one is somehow an extension of the other. We offer a naturalist reply to the charge of circularity by appealing to reliabilist work on the problem of induction, notably Peter Lipton's distinction between self-certifying and non-self-certifying inductive arguments. We show how, for scientific beliefs, a non-self-certifying argument might be made for the reliability of our cognitive faculties in that domain. We call this strategy Humean Bootstrapping. (shrink)

Empirical evidence from developmental psychology and anthropology points out that the human mind is predisposed to conceptualize the world in particular, species-specific ways. These cognitive predispositions lead to universal human commonsense views, often referred to as folk theories. Nevertheless, humans can transgress these views – i.e. they can contradict them with alternative descriptions, they perceive as more accurate – as exemplified in modern sciences. In this paper, I enquire about the cognitive faculties underlying such transgressions. I claim that there are (...) three faculties enabling us to part with these universal commonsense views of the world imposed by our nature. The first is our ability to represent representations – i.e. to form metarepresentations. The second is our ability to produce alternative representations both by explaining a familiar subject matter in terms of the principles governing different conceptual domains than the one that we are predisposed to apply to the subject matter and by directing our mind to new subject matters (for which we have no predisposed conceptual grasp), understanding them in terms of familiar domains. The third, finally, is our ability to give these representations an epistemic orientation. Key words: Human cognition, Domain-specific knowledge systems, Cognitive predispositions, Folk theories, Cognitive flexibility, Human – nonhuman distinction. (shrink)

From the premise that our biology imposes cognitive constraints on our epistemic activities, a series of prominent authors – most notably Fodor, Chomsky and McGinn – have argued that we are cognitively closed to certain aspects and properties of the world. Cognitive constraints, they argue, entail cognitive closure. I argue that this is not the case. More precisely, I detect two unwarranted conflations at the core of arguments deriving closure from constraints. The first is a conflation of what I will (...) refer to as ‘representation’ and ‘object of representation’. The second confuses the cognitive scope of the assisted mind for that of the unassisted mind. Cognitive closure, I conclude, cannot be established from pointing out the (uncontroversial) existence of cognitive constraints. (shrink)

Computational theories of vision typically rely on the analysis of two aspects of human visual function: (1) object and shape recognition (2) co-calibration of sensory measurements. Both these approaches are usually based on an inverse-optics model, where visual perception is viewed as a process of inference from a 2D retinal projection to a 3D percept within a Euclidean space schema. This paradigm has had great success in certain areas of vision science, but has been relatively less successful in understanding perceptual (...) representation, namely, the nature of the perceptual encoding. One of the drawbacks of inverse-optics approaches has been the difficulty in defining the constraints needed to make the inference computationally tractable (e.g. regularity assumptions, Bayesian priors, etc.). These constraints, thought to be learned assumptions about the nature of the physical and optical structures of the external world, have to be incorporated into any workable computational model in the inverse-optics paradigm. But inference models that employ an inverse optics plus structural assumptions approach inevitably result in a na. (shrink)

In the last few decades, there has been a genuine ‘adaptive turn’ in psychiatry, resulting in evolutionary accounts for an increasing number of psychopathologies. In this paper, I explore the advantages and problems with the two main evolutionary approaches to depression, namely the mismatch and persistence accounts . I will argue that while both evolutionary theories of depression might provide some helpful perspectives, the accounts also harbor significant flaws that might question their authority and usefulness as explanations.

Today the modern Darwinian theory of evolution is the unifying theory within the biological sciences. A consideration of its implications for feminism is, however, impossible without a critical evaluation of its history of male bias. The aim of this article is therefore threefold. First, to explain what sexual selection entails. Second, to discuss male bias in and feminist reactions to Darwinian theory in general and sexual selection theory in particular. Third, to demonstrate that it would be a loss for feminism (...) to keep rejecting an evolutionary framework if we want to understand the roots of gender difference. This article is informed by a Darwinian feminist perspective. (shrink)

I raise three puzzles concerning self-deception: (i) a conceptual paradox, (ii) a dilemma about how to understand human cognitive evolution, and (iii) a tension between the fact of self-deception and Davidson’s interpretive view. I advance solutions to the first two and lay a groundwork for addressing the third. The capacity for self-deception, I argue, is a spandrel, in Gould’s and Lewontin’s sense, of other mental traits, i.e., a structural byproduct. The irony is that the mental traits of which self-deception is (...) a spandrel/byproduct are themselves rational. (shrink)

We address the differences between schadenfreude and happiness and those between gluckschmerz and anger. We argue that these emotions are largely elicited by distinct interactions of appraisals that trigger distinct emotional responses. Moreover, we discuss both schadenfreude and gluckschmerz in relation to the emotional lexicon of several languages and conclude that these emotions help us to better understand human behaviour.

In this paper we outline a theoretical account of the relationship between technology and human musicality. An enactive and bio-cultural position is adopted that assumes a close coevolutionary relationship between the two. From this position we aim at clarifying how the present and emerging technologies, becoming embedded and embodied in our life-world, inevitably co-constitute and transform musical practices, skills, and ways of making sense of music. Therefore, as a premise of our scrutiny, we take it as a necessity to more (...) deeply understand the ways that humans become affiliated to the ever-changing instruments of music technology, in order to better understand the coevolutionary impact on learning and other aspects of musicality being constituted together with these instruments. This investigation is particularly motivated by the rapid and diverse development of mobile applications, and their potential impact, as musical instruments, on learning and cognizing music. The term appification refers to enactive processes in which applications (i.e., apps) and their user interfaces, developed for various ecosystems of mobile smart technology, partake in re-organizing our ways of musical acting and thinking. On the basis of the theoretical analysis, we argue that understanding the phenomenon of the human-technology relationship, and its implications for our embodied musical minds, requires acknowledging (1) how apps contribute to conceptual constructing of musical activities, (2) how apps can be designed or utilized in a way that reinforces the epistemological continuum between embodied and abstract sensemaking, and (3) how apps become merged with musical instruments.

In the nineteenth century, there was substantial and sophisticated interest in neuroscience on the part of social theorists, including Comte and Spencer, and later Simon Patten and Charles Ellwood. This body of thinking faced a dead end: it could do little more than identify highly general mechanisms, and could not provide accounts of such questions as `why was there no proletarian revolution?' Psychologically dubious explanations, relying on neo-Kantian views of the mind, replaced them. With the rise of neuroscience, however, some (...) of the problems of concern to earlier thinkers, such as imitation, have revived because of the discovery of neuronal mechanisms, or through fMRI studies. The article reviews the history and discusses the implications of current work for the reconsideration of traditional social theory concepts. It is suggested that certain kinds of bridging work with neuroscience would enable us to answer many questions in social theory that empirical sociology has failed to answer. (shrink)

It is clear throughout Cognitive Gadgets Heyes believes the development of cognitive capacities results from the interaction of genes and experience. However, she opposes cognitive instincts theorists to her own view that uniquely human capacities are cognitive gadgets. Instinct theorists believe that cognitive capacities are substantially produced by selection, with the environment playing a triggering role. Heyes’s position is that humans have similar general learning capacities to those present across taxa, and that sophisticated human cognition is substantially created by our (...) socioculturally transmitted environment. It is a core strategy of Heyes to provide evidence of learning altering a cognitive capacity to conclude that a capacity is a cognitive gadget and not an instinct. We draw on recent work on the evolution of learning preparedness to examine the adequacy of this strategy. In particular, we analyse experimental evolution work showing how selection affects cognition within the laboratory. First, this work reveals that change due to learning can still be retained under genetic assimilation. This suggests that domain-specific adaptation can coexist with learning, moderate nativism, an option missed by the instinct versus gadget distinction. Second, we describe the conditions that select for increased preparedness in learning: certainty, reliability, and particular costs. We consider how these conditions can be used when conducting evolutionary reasoning about cognition, applying them to the important capacity for imitation. We find that the conditions lend theoretical support to moderate nativism about the capacity to imitate, which is supported by psychological evidence. (shrink)

The development of cognitive capacities depends on environmental conditions, including various forms of scaffolding. As a result, the evolution of cognition depends on the evolution of activities that provide scaffolding for cognitive development. Non-human animals reared and trained in environments heavily scaffolded with human social interaction can acquire non-species-typical knowledge, skills, and capacities. This can potentially shed light on some of the changes that paved the way for the evolution of distinctively human behavioral capacities such as language, advanced social cognition, (...) and elaborate forms of tool craft. In this light, I revisit several widely known—but also widely misunderstood—cases of exceptional animals and argue that each of these cases provides clues about key innovations in our own evolutionary history.

In distinguishing itself from other distributed approaches to cognition, Anderson's theory of neural reuse is susceptible to some of the same criticisms that have been leveled at modular approaches. Specifically, neural reuse theories state that: (1) the of a given brain circuit is fixed, rather than shaped by its input, and (2) that high-level cognitive behaviors can be cleanly mapped onto a specific set of brain circuits in a non-contextualized manner.

In the Meno, Phaedo, and Phaedrus, Plato outlines the controversial thesis of a priori knowledge that all learning is a form of recollection—anamnesis. He uses this as an argument for the immortality of the soul via reincarnation. Because of this latter claim, the thesis is widely mocked by contemporary evolutionarily-informed materialists. But we can safely reject the metaphysical claim without abandoning the insight of the epistemological one. And indeed, modern evolutionary theory can explain how learning—at least of the sort that (...) depends on certain a priori concepts—can be a kind of recollection. Through this metaphor, natural selection is a process by which information about the world is transmitted across time. When we learn by reasoning about a priori knowledge, then, we in an important sense rely on information in our genomes—if not our souls—information acquired by the process of natural selection—if not conscious acquisition. Thinking of a priori knowledge with the metaphor of anamnesis elucidates two essential features of the relationship between epistemology and ontology. First, it emphasizes that there is necessarily a time-delay between our a priori knowledge and the universe to which it bears a relationship, if any. Second, it clarifies that a priori knowledge is knowledge that enhances reproductive fitness—which could well be because it reflects ontology faithfully, but could as easily be a kind of innate nominalism.

How can anyone be rational in a world where knowledge is limited, time is pressing, and deep thought is often an unattainable luxury? Traditional models of unbounded rationality and optimization in cognitive science, economics, and animal behavior have tended to view decision-makers as possessing supernatural powers of reason, limitless knowledge, and endless time. But understanding decisions in the real world requires a more psychologically plausible notion of bounded rationality. In Simple heuristics that make us smart (Gigerenzer et al. 1999), we (...) explore fast and frugal heuristics – simple rules in the mind's adaptive toolbox for making decisions with realistic mental resources. These heuristics can enable both living organisms and artificial systems to make smart choices quickly and with a minimum of information by exploiting the way that information is structured in particular environments. In this précis, we show how simple building blocks that control information search, stop search, and make decisions can be put together to form classes of heuristics, including: ignorance-based and one-reason decision making for choice, elimination models for categorization, and satisficing heuristics for sequential search. These simple heuristics perform comparably to more complex algorithms, particularly when generalizing to new data – that is, simplicity leads to robustness. We present evidence regarding when people use simple heuristics and describe the challenges to be addressed by this research program. Key Words: adaptive toolbox; bounded rationality; decision making; elimination models; environment structure; heuristics; ignorance-based reasoning; limited information search; robustness; satisficing; simplicity.

Aspects of the history of behavioural science are reviewed, pointing to its fragmented and faction-ridden nature. The emergence of evolutionary psychology (EP) is viewed in this context. With the help of a dual-layered model of behavioural control, the case is made for a more integrative perspective towards EP. The model's application to both behaviour and complex human information processing is described. Similarities in their control are noted. It is suggested that one layer of control (‘on-line’) corresponds to the encapsulated modules (...) of EP whereas the off-line controls provide the plasticity and flexibility suggested by its critics.

Academic popularizers of the new field of evolutionary psychology make notable appeals to William James to bolster their doctrine. In particular, they cite James’ remark that humans have all the “impulses” animals do and many more besides to shore up their claim that people’s “instincts” account for their flexibility. This essay argues that these scholars misinterpret James on the instincts. Consciousness (which they find inscrutable) explains cognitive flexibility for James. The evolutionary psychologists’ appeal to James is, therefore, unwarranted and, given (...) the conditions relevant to the public and professional audiences they address, also ineffective as a rhetorical tool for enlisting new recruits.

he mystery of consciousness is among the most important questions pondered upon, not only in philosophy but also in the cognitive science, psychology, neurobiology and other sciences. The problem of consciousness has been traditionally dealt by philosophy, but its importance in explaining mental phenomena has made it a subject matter for other sciences that emerged later. Each philosopher and scientist has followed his own method in defining it, and arriving at a universal agreement on its definition has become difficult. In (...) philosophy, ‘consciousness’ does not have a definition in terms of genus and differentia, or the necessary and sufficient conditions. On the one hand, idealists put all their efforts into explaining consciousness as a separate entity, without stepping away from their traditional path, because they believe that thinking, experience, and free will are not the properties of the physical entity. On the other hand, the scientific world puts its efforts into reducing consciousness to electrical and neurochemical processes of the brain because they believes that the brain works like a biologically programmed computer. Our approach to consciousness varies between these two explanations. We would like to address the problem of consciousness at two levels: cosmic and individual. The basic thesis of this paper is: everything that we know is something that we experience and everything that we experience is a form arising within consciousness. (shrink)

Selection pressure from health risk is hypothesized to have shaped adaptations motivating individuals to attempt to become valued by other individuals by generously and recurrently providing beneficial goods and/or services to them because this strategy encouraged beneficiaries to provide costly health care to their benefactors when the latter were sick or injured. Additionally, adaptations are hypothesized to have co-evolved that motivate individuals to attend to and value those who recurrently provide them with important benefits so they are willing in turn (...) to provide costly care when a valued person is disabled or in dire need. Individuals in egalitarian foraging bands can provide a number of valuable benefits, such as defense, diplomacy, food, healing, information, technical skill, or trading savvy. We therefore expect that humans have evolved psychological mechanisms motivating the pursuit and cultivation of a difficult-to-replace social role based on the provisioning of a benefit that confers a fitness advantage on its recipients. We call this phenomenon social niche specialization. One such niche that has been well-documented is meat-sharing. Here we present cross-cultural evidence that individuals cultivate two other niches, information and tool production, that serve (among other things) to buffer health risk. (shrink)

This paper offers an evolutionary account of chronic pain. Chronic pain is a maladaptive by-product of pain mechanisms and neural plasticity, both of which are highly adaptive. This account shows how evolutionary psychology can be integrated with Flanagan's natural method, and in a way that avoids the usual charges of panglossian adaptationism and an uncritical commitment to a modular picture of the mind. Evolutionary psychology is most promising when it adopts a bottom-up research strategy that focuses on basic affective and (...) motivational systems (as opposed to higher cognitive functions) that are phylogenetically deep.

Two recent attempts to clarify misunderstandings about the nature of cultural evolution came to very different conclusions, based on very different understandings of what evolves and how. This paper begins by examining these two ‘clarifications’ in order to reveal their key differences, and goes on to rethink how culture evolves by focussing on the role of cognitive structure, or worldview.

Recently Geoffrey Miller has suggested that humor evolved through sexual selection as a signal of "creativity," which in turn implies youthfulness, intelligence, and adaptive unpredictability. Drawing upon available empirical studies, I argue that the evidence for a link between humor and creativity is weak and ambiguous. I also find only tenuous support for Miller’s assumption that the attractiveness of the "sense of humor" is to be found in the wittiness of its possessor, since those who use the phrase often seem (...) to associate it with the affects of relatively mirthless "bonding" laughter. Humor, I conclude, may have evolved as an instrument for achieving broad social adhesiveness and for facilitating the individual’s maneuverability within the group, but that it evolved through sexual selection has yet to be convincingly demonstrated.

Evolutionary psychology and social constructionism are widely regarded as fundamentally irreconcilable approaches to the social sciences. Focusing on the study of the emotions, we argue that this appearance is mistaken. Much of what appears to be an empirical disagreement between evolutionary psychologists and social constructionists over the universality or locality of emotional phenomena is actually generated by an implicit philosophical dispute resulting from the adoption of different theories of meaning and reference. We argue that once this philosophical dispute is recognized, (...) it can be set to the side. When this is done, it becomes clear that the two approaches to the emotions complement, rather than compete with, one another. (shrink)

There have been few tests of whether exposure to naturalistic or experimental disease-threat inductions alter disgust sensitivity, although it has been hypothesized that this should occur as part of disgust’s disease avoidance function. In the current study, we asked Macquarie university students to complete measures of disgust sensitivity, perceived vulnerability to disease, hand hygiene behavior and impulsivity, during Australia’s Covid-19 pandemic self-quarantine period, in March/April 2020. These data were then compared to earlier Macquarie university, and other local, and overseas student (...) cohorts, to determine if disgust sensitivity and the other measures, were different in the lockdown sample. The most consistent finding in the lockdown sample was of higher core disgust sensitivity, with some evidence of greater germ aversion on the PVD, and an increase in hand and food-related hygiene, but with little change in impulsivity. The consistency with which greater core disgust sensitivity was observed, suggests exposure to a highly naturalistic disease threat is a plausible cause. Greater disgust sensitivity may have several functional benefits and may arise implicitly from the threat posed by the Covid-19 pandemic. (shrink)

It is generally agreed that dispositions cannot be analyzed in terms of simple subjunctive conditionals (because of what are called “masked dispositions” and “finkish dispositions”). I here defend a qualified subjunctive account of dispositions according to which an object is disposed to Φ when conditions C obtain if and only if, if conditions C were to obtain, then the object would Φ ceteris paribus . I argue that this account does not fall prey to the objections that have been raised (...) in the literature. (shrink)

There has been significant debate over both the imiplications and the merit of Leopold's land ethic. I consider the two most prominent objections and a resolution to them. One of these objections is that, far from being an alternative to an “economic” or cost‐benefit perspective on environmental issues, Leopold's land ethic merely broadens the range of economic considerations to be used in addressing such issues. The other objection is that the land ethic is a form of “environmental fascism” because it (...) subordinates the welfare of humans to the good of the ecological whole. I argue that these objections are based on a fundamental misunderstanding of his theory by advocates and detractors alike. The land ethic is centrally a psychological theory of moral development and ecological rationality that advocates a shift in the way that environmental problems are conceptualized and approached.

There is an enduring tension in thinking about the architecture of systems that select behaviours, including evolved organisms. One line of reasoning supports convergence in control systems and conversion of the values of all options into a common currency, in part because this seems the best or only way of trading off costs and benefits associated with outcomes of varying types. A competing consideration supports parallelism or other forms of fragmentation, because of inefficiencies associated with integration, and suspicion towards general-purpose (...) cognitive systems. In addition, recent neuroscience has given particular attention to the question of how partly independent ‘habit based’ and ‘planning based’ decision-systems might interact. The issues here are, at least in part, a special case of the more general integration versus parallelism tension. This tension provides a useful framework for thinking about the implementation of different kinds of sensitivity to risks of various types, the variety of mechanisms by means of which risk sensitivity might be modulated, and how risk might be traded off against other components of value or disincentive. I describe the tension, briefly survey some of the relevant empirical evidence, and conclude with tentative observations on the topic of risk. (shrink)

. In Minding God Gregory Peterson takes a careful look at the kind of freedom that human persons have. He concludes that humans are constrained to be free and unpacks this into a version of compatibilism. That is, humans are not metaphysically free under current existence because of the causal determination inherent in their physical nature, but they can take credit for the origination of selfforming decisions because the causes occur inside of us. Peterson does advocate an eschatological hope looking (...) forward to the breaking of causal determination by God's own action. Thus, Minding God presents an eschatologically limited compatibilism. Compatibilism of any kind, however, presents serious challenges to most Christian theologies and to many religious traditions broadly considered. After I interpret Peterson's position I make the argument that compatibilism is neither desirable nor required for a theological anthropology intent on serious engagement of cognitive science.

Perception of music and speech is based on similar auditory skills, and it is often suggested that those with enhanced music perception skills may perceive and learn novel words more easily. The current study tested whether music perception abilities are associated with novel word learning in an ambiguous learning scenario. Using a cross-situational word learning (CSWL) task, nonmusician adults were exposed to word-object pairings between eight novel words and visual referents. Novel words were either non-minimal pairs differing in all sounds (...) or minimal pairs differing in their initial consonant or vowel. In order to be successful in this task, learners need to be able to correctly encode the phonological details of the novel words and have sufficient auditory working memory to remember the correct word-object pairings. Using the Mistuning Perception Test (MPT) and the Melodic Discrimination Test (MDT), we measured learners’ pitch perception and auditory working memory. We predicted that those with higher MPT and MDT values would perform better in the CSWL task and in particular for novel words with high phonological overlap (i.e., minimal pairs). We found that higher musical perception skills led to higher accuracy for non-minimal pairs and minimal pairs differing in their initial consonant. Interestingly, this was not the case for vowel minimal pairs. We discuss the results in relation to theories of second language word learning such as the Second Language Perception model (L2LP).

The bare theory is a no-collapse version of quantum mechanics which predicts certain puzzling results for the introspective beliefs of human observers of superpositions. The bare theory can be interpreted to claim that an observer can form false beliefs about the outcome of an experiment which produces a superpositional result. It is argued that, when careful consideration is given to the observer’s belief states and their evolution, the observer does not end up with the beliefs claimed. This result leads to (...) questions about whether there can be any allure for no-collapse theories as austere as the bare theory. (shrink)
