An automated swim alley for small animals: II. Training and procedures

Experiments were conducted to establish training procedures and testing conditions that produce uniform and reliable swimming performance of rats in an automated swim alley. Data are given on the effect of water temperature and of platform rest interval on swimming speeds. In this system, rats will swim intermittently for as long as 24 h for a distance of more than 7 km.     

Consciousness and Criterion: On Block's Case for Unconscious Seeing

Block ( 2012 ) highlights two experimental studies of neglect patients which, he contends, provide ‘dramatic evidence’ for unconscious seeing. In Block's hands this is the highly non‐trivial thesis that seeing of the same fundamental kind as ordinary conscious seeing can occur outside of phenomenal consciousness. Block's case for it provides an excellent opportunity to consider a large body of research on clinical syndromes widely held to evidence unconscious perception. I begin by considering in detail the two studies of neglect to which Block appeals. I show why their interpretation as evidence of unconscious seeing faces a series of local difficulties. I then explain how, even bracketing these issues, a long‐standing but overlooked problem concerning our criterion for consciousness problematizes the appeal to both studies. I explain why this problem is especially pressing for Block given his view that phenomenal consciousness overflows access consciousness. I further show that it is epidemic—not only affecting all report‐based studies of unconscious seeing in neglect, but also analogous studies of the condition most often alleged to show unconscious seeing, namely blindsight.     

Cultural worldviews and climate change: A view from China

We investigated the association between cultural worldviews and climate change risk perceptions, support for climate friendly policies and climate change mitigation behaviours in a large Chinese sample. Items from Dake's cultural theory scales and Kahan's cultural cognition scale were presented to a Qualtrics online panel consisting of 515 Mandarin‐speaking residents of Beijing. A series of factor analyses revealed that the combined item sets were best represented by four‐dimensions: hierarchism, individualism, egalitarianism and fatalism. Mediation analysis revealed that respondents with egalitarian and non‐fatalist worldviews perceived greater risk associated with climate change, which in turn predicted greater support for policies to manage climate change and increased mitigation behaviour. In addition, respondents who scored high on individualism were less likely to support climate change policies, but this effect was not mediated by risk perceptions. Overall, our results suggest cultural worldviews may influence policy support both directly and indirectly through risk perceptions.     

Social Desirability in Patients Seeking Surgical Treatment for Dentofacial Disharmony: Associations with Psychological Distress and Motivation for Treatment

The role of socially desirable responding in the report of treatment motivation and psychological distress by patients seeking surgical treatment for dentofacial disharmony was explored. Participants completed the Balanced Inventory of Desirable Responding (BIDR; Paulhus, 1988), which measures two components of socially desirable responding (SDR): impression management (IM), which is the purposeful tailoring of answers in order to create the most positive social image, and self-deceptive positivity (SDE), which is an honest, but overly positive self-presentation. When simple bivariate relationships were examined, statistically significant inverse associations were observed between socially desirable responding and specific motives for treatment and between SDR and psychological distress. However, the relationship between socially desirable responding and motives for treatment disappeared when the effect of psychological distress was controlled. The positive relationship between psychological distress and the report of social well-being, and self-image motives for treatment remained statistically significant even after the variance attributable to socially desirable responding was removed. Implications of the findings for the evaluation of psychological distress and treatment motivation in this population are discussed.     

The Place of Dialogue Theory in Logic,Computer Science and Communication Studies

Dialogue theory, although it has ancient roots, was put forward in the 1970s in logic as astructure that can be useful for helping to evaluate argumentation and informal fallacies.Recently, however, it has been taken up as a broader subject of investigation in computerscience. This paper surveys both the historical and philosophical background of dialoguetheory and the latest research initiatives on dialogue theory in computer science. The main components of dialogue theory are briefly explained. Included is a classification of the main types of dialogue that, it is argued, should provide the central focus for studying many important dialogue contexts in specific cases. Following these three surveys, a concluding prediction is made about the direction dialogue theory is likely to take in the next century, especially in relation to the growing field of communication studies.     

Divorce mediation: the impact of mediation on the psychological well‐being of children and parents

This study evaluated levels of psychological distress experienced by children (aged 4–16) and parents at the beginning of and one month after mediation for child‐related disputes. In contrast to previous research, this study employed both child‐ and parent‐reports of child outcome. Mediation was associated with reductions in child‐reported, though not parent‐reported, child psychological distress and with reductions in parent‐reports of their own psychological distress. The negotiation of successful agreements in mediation was not related to improved psychological well‐being of family members. The difficulties encountered (i.e. small numbers, low response rate) render the results tentative. Implications of the findings for future research are discussed.

The Shifting Border Between Perception and Cognition

The distinction between perception and cognition has always had a firm footing in both cognitive science and folk psychology. However, there is little agreement as to how the distinction should be drawn. In fact, a number of theorists have recently argued that, given the ubiquity of top‐down influences (at all levels of the processing hierarchy), we should jettison the distinction altogether. I reject this approach, and defend a pluralist account of the distinction. At the heart of my account is the claim that each legitimate way of marking a border between perception and cognition deploys a notion I call ‘stimulus‐control.’ Thus, rather than being a grab bag of unrelated kinds, the various categories of the perceptual are unified into a superordinate natural kind (mutatis mutandis for the complimentary categories of the cognitive).
