In this article, we consider infants’ acquisition of foundational aspects of language and emotion through the lens of statistical learning. By taking a comparative developmental approach, we highlight ways in which the learning problems presented by input from these two rich communicative domains are both similar and different. Our goal is to encourage other scholars to consider multiple domains of human experience when developing theories in developmental cognitive science.

Laland and colleagues have sought to challenge the proximate–ultimate distinction claiming that it imposes a unidirectional model of causation, is limited in its capacity to account for complex biological phenomena, and hinders progress in biology. In this article the core of their argument is critically analyzed. It is claimed that contrary to their claims Laland et al. rely upon the proximate–ultimate distinction to make their points and that their alternative conception of reciprocal causation refers to phenomena that were already accounted (...) for by standard theory.

It is argued that the Tractatus Project of Logical Atomism, in which the world is conceived of as the totality of independent atomic facts, can usefully be understood by conceiving of each fact as a bit in logical space. Wittgenstein himself thinks in terms of logical space. His elementary propositions, which express atomic facts, are interpreted as tuples of co-ordinates which specify the location of a bit in logical space. He says that signs for elementary propositions are arrangements of names. (...) Here, the names are understood as numerical symbols specifying coordinates. It is argued that, using this approach, the so-called colour-exclusion problem, which was Wittgensteins reason for abandoning the Tractatus, is in fact soluble. However, if logical space is a continuum then some coordinates will need to be expressed by numerical symbols that are infinite in size. How is this to be understood in Tractatus terms? It is shown that, in the Tractatus, Wittgenstein did recognise the possibility of infinite propositions and sentences expressing them. At first sight his approach to infinite sentences, and the approach of the present paper, seem to differ, but it is argued that the difference is superficial. Finally, we address the question of whether Logical Atomism is viable and this raises issues concerning its relationship to natural science. (shrink)

This book explores the principal issues involved in bridging the gap between the pure theory of consumer behavior and its empirical implementation. The authors focus upon the structure of preferences, the treatment of demographic variables, the treatment of dynamics, and the specification of the stochastic structure of the demand system.

This article draws on scientific explanations of obesity to motivate the creation of a system of paternalistic public health interventions into the obesity epidemic. Libertarian paternalists argue that paternalism is warranted in light of the cognitive limits of human decision-making abilities. There are further, specific biological limits on our capacity to choose and maintain a healthy diet. These biological facts strengthen the general motivation for libertarian paternalism. As a consequence, the creation of a system of paternalistic public health interventions into (...) the obesity epidemic is warranted. (shrink)

Three arguments are proposed against the idea that ordinary talk about the mind constitutes a folk psychology, a sort of prescientific theory which explains human behaviour and which is ripe for replacement by a neurological or computational theory with better scientific credentials. First, not all talk of the mind is introduced to explain in the way assumed by those who think that mental talk hypothesizes inner processes to explain behaviour. Second, the individuation of the behaviour which is explained by the (...) inner processes itself requires reference to ?mental? states such as intentions or desires. Consequently the project is circular. Finally, scientific theory is a practice with a history which may be matched in the case of ordinary talk of the mind. Certainly ordinary talk of motives, intentions, and thoughts may be infected by the theorizing of economists and sociologists et al., but it is impossible that all talk of the mind should be theoretical in this way.

The human person makes great demands on the physician and calls for unique attention. Hence the doctor-patient relationship calls for the highest ideals of kindness, patience, trustworthiness, generosity and skill. The Catholic physician brings to these demands a specific meaning: ministering to the sick is to see Christ in them and to show Him to them.

The Model Penal Code’s ‘De Minimis’ provisions (§ 2.12) cover different kinds of case in which, for reasons of equity, a prosecution should be dismissed. An exploration of these different cases illuminates some general issues about the structure of the criminal process, and about the processes of criminalization. These include the significance of the difference between dismissing a case and acquitting the defendant, and of the distinction between offences and defences; whether criminal offences should always be so defined that they (...) specify at least a pro tanto wrong, or may sometimes legitimately specify only a prima facie wrong – and whether this is consistent with the presumption of innocence; what kinds of conduct we can properly be expected to answer for in a criminal court; and the proper division of responsibilities between legislatures, prosecutors and courts in determining what kinds of conduct are to be defined and treated as criminal wrongs.

A categorical structure suitable for interpreting polymorphic lambda calculus (PLC) is defined, providing an algebraic semantics for PLC which is sound and complete. In fact, there is an equivalence between the theories and the categories. Also presented is a definitional extension of PLC including "subtypes", for example, equality subtypes, together with a construction providing models of the extended language, and a context for Girard's extension of the Dialectica interpretation.

Aim To study the views of people in a largely Muslim country, Kuwait, of the acceptability of a life-ending action such as physician-assisted suicide (PAS). Method 330 Kuwaiti university students judged the acceptability of PAS in 36 scenarios composed of all combinations of four factors: the patient's age (35, 60 or 85 years); the level of incurability of the illness (completely incurable vs extremely difficult to cure); the type of suffering (extreme physical pain or complete dependence) and the extent to (...) which the patient requests a life-ending procedure, euthanasia or PAS (no request, some form of request, repeated requests). In all scenarios, the patients were women who were receiving the best possible care. The ratings were subjected to cluster analysis and analyses of variance. Results Five clusters were found. For 44%, PAS was always very unacceptable, no matter what the circumstances. For 23%, it was unacceptable, but less so if the patient was older or requested it repeatedly. For 16%, it was unacceptable if the patient was young but was acceptable if the patient was elderly. For 5%, it was unacceptable if the patient had extreme pain but was acceptable if completely dependent. For 11%, it was unacceptable if the patient did not request it but acceptable if she did. Conclusion The majority of the Kuwaiti university students opposed PAS either categorically or with a slight variation according to circumstances. Nonetheless, a minority approved of PAS in some cases, particularly when the patient was elderly. (shrink)

The paper argues that the rich cognitive abilities of humans are the result of a unique functional system in the human brain which is absent in the nonhuman brain. This "frontal feedback system" is suggested to have evolved in the transition from the great apes to humans and is a product of a reversal in the preferred direction of information flow in the human cortex due to the phylogenetic enlargement of the human frontal lobe. The frontal feedback system forms an (...) autonomous functional unit in the cortex whereby action-schemes in frontal cortices continually create fictitious sensory scenarios in posterior sensory cortices by manipulating the release of sensory representations there. These internal scenarios are created free of environmental constraints and reflect the human's internal cognitive and language processes. Nonhumans do not have a frontal feedback system and their internal cognitive processes are stimulus-bound. Evidence in support of the proposal is presented and some implications of the frontal feedback model for human experience are discussed. (shrink)

The discovery of the microworld presented a serious trial for many systems of views held by mankind, including its logic. This world was found to lack the familiar solid bodies, the unchanging particles and interrelations between them, the reflection of which, in one way or another, is the logic of the macroscopic world. What elementary particle physics encountered in the microscopic world seemed illogical: the rest-mass of a particle equals zero; a part that is not smaller than the whole; a (...) particle that in diffraction experiments moved like a wave; and much else that was unusual and strange in the properties of elementary particles. One of these properties was actually so named by physicists — "strangeness.". (shrink)
