According to the prevailing paradigm in social-cognitive neuroscience, the mental states of individuals become shared when they adapt to each other in the pursuit of a shared goal. We challenge this view by proposing an alternative approach to the cognitive foundations of social interactions. The central claim of this paper is that social cognition concerns the graded and dynamic process of alignment of individual minds, even in the absence of a shared goal. When individuals reciprocally exchange information about each other's (...) minds processes of alignment unfold over time and across space, creating a social interaction. Not all cases of joint action involve such reciprocal exchange of information. To understand the nature of social interactions, then, we propose that attention should be focused on the manner in which people align words and thoughts, bodily postures and movements, in order to take one another into account and to make full use of socially relevant information.

As Van Dijk proposed in the first issue of Discourse and Communication, the main purpose of this journal is to bridge the two cross-disciplines of communication and discourse studies. Given this goal, this article sought to help clear the ground for such interdisciplinary development by investigating how organizational researchers use the terms `discourse' and `communication' and cast discourse—communication relationships. By reviewing 112 organizational discourse studies from major journals in communication, organizational studies, and interdisciplinary journals published between 1981 and 2006, this (...) study identified diverse conceptualizations of these basic concepts. The findings help dispel some of the misunderstandings that scholars from one research field may possess toward the other and sort through some, if not all, the confusions regarding the terms `discourse', `communication', and their relationships.

A unifying theory of general anesthetic-induced unconsciousness must explain the common mechanism through which various anesthetic agents produce unconsciousness. Functional-brain-imaging data obtained from 11 volunteers during general anesthesia showed specific suppression of regional thalamic and midbrain reticular formation activity across two different commonly used volatile agents. These findings are discussed in relation to findings from sleep neurophysiology and the implications of this work for consciousness research. It is hypothesized that the essential common neurophysiologic mechanism underlying anesthetic-induced unconsciousness is, as with (...) sleep-induced unconsciousness, a hyperpolarization block of thalamocortical neurons. A model of anesthetic-induced unconsciousness is introduced to explain how the plethora of effects anesthetics have on cellular functioning ultimately all converge on a single neuroanatomic/neurophysiologic system, thus providing for a unitary physiologic theory of narcosis related to consciousness.

This article discusses the role of moment-to-moment affect dynamics in mental disorder and aims to integrate recent literature on this topic in the context of complex dynamical system theory. First, we will review the relevance of temporal and contextual aspects of affect dynamics in relation to psychopathology. Related to this, we will discuss recent insights resulting from a network view on affect dynamics in psychopathology. Next, we explore how we can reconcile literature findings from a perspective of complex dynamical system (...) theory. Finally, future directions with regard to personalized assessment of risk and diagnostic use are discussed. (shrink)

Gametes, tissue, and organs can be taken from the dying or dead for reproduction, transplantation, and research. Whole bodies as well as parts can be used for teaching anatomy. While these uses are diverse, they have an ethical consideration in common: the claims of the people whose bodies are used. Is some use permissible only when people have consented to the use, actually wanted the use, would have wanted the use, not opposed the use, or what? The aim of this (...) article is to make progress in answering these questions. Initially I assume knowledge of people’s desires in order to test whether consent is directly required by their rights without worrying about mistaken uses against their wishes. I claim consent is not directly required by people’s rights. If we know people wanted or would want a use, their rights permit the use, but if we know they wanted or would want not to be used, their rights do not permit the use. The knowledge assumption is then dropped and the question becomes how to decide what to do when the wishes of rightholders are not known. I suggest working out what to do when wishes are known and then adjusting, on the basis of whatever evidence there is, for probability and strength of desire. There are other considerations too, for instance about default rules. The key general comment here is that, in setting rules, the costs to rightholders in not getting what they want needs to be taken into account. The final section tries to show that, in setting these rules, mistaken uses are not to be taken as worse than mistaken failure to use. (shrink)
