Differential effects of object orientation on imaginary object /viewer transformations

Given a specific view of a simple symmetrical object, participants were asked whether a certain imaginary transformation could result in a second viewed image. An experiment was conducted in which the participants had either to mentally rotate an object or to imagine themselves looking at the object from another position (i.e., the object-based condition and the viewer-based condition, respectively). In the experiment, combinations of these imagery tasks (i.e., the combined conditions) were also included. The symmetrical objects could be oriented horizontally or vertically. The performance in the object-based conditions was generally equal to or better than the performance in the viewer-based conditions. In addition, there were more confusions for shapes with a horizontal orientation, especially when viewer-based upside-down rotations were involved, with an apparent mediating role of object rotation in the combined conditions.     

Ingroup and outgroup differences in face detection

Humans show improved recognition for faces from their own social group relative to faces from another social group. Yet before faces can be recognized, they must first be detected in the visual field. Here, we tested whether humans also show an ingroup bias at the earliest stage of face processing – the point at which the presence of a face is first detected. To this end, we measured viewers' ability to detect ingroup (Black and White) and outgroup faces (Asian, Black, and White) in everyday scenes. Ingroup faces were detected with greater speed and accuracy relative to outgroup faces (Experiment 1). Removing face hue impaired detection generally, but the ingroup detection advantage was undiminished (Experiment 2). This same pattern was replicated by a detection algorithm using face templates derived from human data (Experiment 3). These findings demonstrate that the established ingroup bias in face processing can extend to the early process of detection. This effect is ‘colour blind’, in the sense that group membership effects are independent of general effects of image hue. Moreover, it can be captured by tuning visual templates to reflect the statistics of observers' social experience. We conclude that group bias in face detection is both a visual and a social phenomenon.     

Cognitive correlates of depressive symptoms in 11-year-old children

Self-reports of depressive symptoms were obtained for 792 11-year-old New Zealand children using a structured interview. The aim of the present study was to test the hypothesis that depressive symptomatology in children is associated with impairment on cognitive tasks. The results did not support this hypothesis. Depression was unrelated to performance on various subscales of the WISCR, whereas self-reported inattention was associated with poor performance. Depressive symptoms, however, were significantly related to lower self-esteem and a poorer self-perception of scholastic ability.The Dunedin Multidisciplinary Health and Development Research Unit is supported by the Medical Research Council of New Zealand and the Departments of Education and Health, and involves several departments of the University of Otago. Much of the data are gathered by voluntary workers from the Dunedin community. The authors are indebted to the many people whose contributions make this ongoing study possible.     

Speech act conditions as tools for reconstructing argumentative discourse

According to the pragma-dialectical approach to argumentation, for analysing argumentative discourse, a normative reconstruction is required which encompasses four kinds of transformations. It is explained in this paper how speech act conditions can play a part in carrying out such a reconstruction. It is argued that integrating Searlean insights concerning speech acts with Gricean insights concerning conversational maxims can provide us with the necessary tools. For this, the standard theory of speech acts has to be amended in several respects and the conversational maxims have to be translated into speech act conditions. Making use of the rules for communication thus arrived at, and starting from the distribution of speech acts in a critical discussion as specified in the pragma-dialectical model, it is then demonstrated how indirect speech acts are to be transformed when reconstructing argumentative discourse.     

Cognitive and Attitudinal Factors in the Analysis of Alternatives to Binge Drinking1

The present study examined cognitive and attitudinal factors relevant to binge-drinking tendencies in a college sample. Results indicate that positive expectations about binge-drinking activities were related to binge-drinking tendencies. Binge-drinking tendencies were also negatively related to expectations regarding nonbinge-drinking alternatives. General attitudes toward drinking and normative influences were found to have complex influences on binge-drinking tendencies involving indirect, direct, and moderated effects. The findings are discussed with respect to developing prevention programs.     

ArtWare: Macintosh multimedia software for aesthetics research

This paper describes ArtWare, a HyperCard stack for the Apple Macintosh that allows researchers to configure and run simple experiments in visual aesthetics. ArtWare allows researchers to (1) choose paintings or other works of art from commercially available laser discs to use as stimuli, (2) create and edit sets of semantic differential response scales, and (3) create an experiment stack that randomizes the presentation of stimuli and scales as well as collects data from subjects. In addition, the paper discusses revisions planned for the current software to broaden its utility to areas beyond visual aesthetics.     

Agoraphobia and the hyperventilation syndrome

One of the causes of agoraphobic complaints is the fear of having an attack of physical complaints in public places. The Hyperventilation Syndrome (HVS) with its diverse symptoms seems to fit well in this model. Hyperventilation symptoms are threatening, because for most subjects they occur unexpectedly and without a clear reason. An investigation was made into how often the HVS and the agoraphobic syndrome appeared together and into the causal relationship between both syndromes. About 60% of the agoraphobic patients suffered from hyperventilation complaints and about 60% of the HVS patients were agoraphobic. Most patients mentioned the fear of having an attack as an important reason for their agoraphobic complaints, and this applied especially in the case of the HVS.     

An Examination of the Relationships Between Personality,Attitudes, and Cognitions Relevant to Alcohol-Impaired Driving Tendencies1

Previous research has explored the domain of legal and educational prevention in regard to the phenomena of accidents and injuries caused by drinking and driving. Most investigations of psychological factors attempt to distinguish characteristics of drunk drivers relative to the general driving population or controls matched on driving risk variables. In contrast, the present research concentrated on the examination of the process by which empirically derived personality and general attitudinal constructs operate within a cognitive framework to influence the decision to drive. Four conceptual models were proposed that suggested the presence of direct, indirect, and moderated effects of personality and general attitudinal constructs on cognitions relevant to drunk-driving tendencies. Support was observed for a model suggesting the presence of indirect, direct, and moderating effects for the general attitudinal construct driving aggression, and support for an indirect effects model for the personality variable emotional control. The implications of these findings are discussed in the context of utilizing personality and general attitudinal constructs to improve short term cognitive-based interventions.
