The influence of natural contour and face size on the spatial frequency tuning for identifying upright and inverted faces

Psychological Research - It has previously been proposed that holistic face processing is based on low spatial frequencies (SFs) whereas featural processing relies on higher SFs, a hypothesis still...     

Interpersonal aggression and team effectiveness: The mediating role of team goal commitment

This study examines the detrimental effect that interpersonal aggressive behaviours may have on two dimensions of team effectiveness, namely team performance and team viability. Moreover, this study investigates the mediating role of team goal commitment in these relationships. Data were collected from 97 work teams (341 members and 97 immediate supervisors) working in a public safety organization. The results indicate that interpersonal aggression is negatively related to team performance and team viability. The results also show that team goal commitment exercises a complete mediating role with regard to these relationships. Overall, this study highlights potential negative consequences of interpersonal aggression at the team level.     

Seeing is believing: the effect of brain images on judgments of scientific reasoning

Brain images are believed to have a particularly persuasive influence on the public perception of research on cognition. Three experiments are reported showing that presenting brain images with articles summarizing cognitive neuroscience research resulted in higher ratings of scientific reasoning for arguments made in those articles, as compared to articles accompanied by bar graphs, a topographical map of brain activation, or no image. These data lend support to the notion that part of the fascination, and the credibility, of brain imaging research lies in the persuasive power of the actual brain images themselves. We argue that brain images are influential because they provide a physical basis for abstract cognitive processes, appealing to people's affinity for reductionistic explanations of cognitive phenomena.     

Assessing interpersonal aspects of schizoid personality disorder: preliminary validation studies

In 2 studies, we examined the reliability and validity of an interpersonal measure of schizoid personality disorder (SZPD) based on nonverbal behaviors and interpersonal interactions occurring during interviews. A total of 556 male jail inmates in the United States participated in Study 1; 175 mentally disordered offenders in maximum security hospitals in the United Kingdom participated in Study 2. Across both samples, scores on the Interpersonal Measure of Schizoid Personality Disorder (IM-SZ) exhibited adequate reliability and patterns of correlations with other measures consistent with expectations. The scale displayed patterns of relatively specific correlations with interview and self-report measures of SZPD. In addition, the IM-SZ correlated in an expected manner with features of psychopathy and antisocial personality and with independent ratings of interpersonal behavior. We address implications for assessment of personality disorder.     

Resistance to Interference of Olfactory Perceptual Learning

The Psychological Record - Olfactory memory is especially persistent. The current study explored whether this applies to a form of perceptual learning, in which experience of an odor mixture...     

The effect of causal knowledge on judgments of the likelihood of unknown features

People frequently infer unknown aspects of an entity based on their knowledge about that entity. The current study reports a novel phenomenon, an inductive bias people have in making such inferences. Upon learning that one symptom causes another in a person, both undergraduate students (Experiment 1) and clinicians (Experiment 2) judged that an unknown feature associated with the cause-symptom was more likely to be present in that person than an unknown feature associated with the effect-symptom. Thus, these findings suggest a specific mechanism in which causal explanations influence one’s representation of and inferences about an entity. Implications for clinical reasoning and associative models of conceptual knowledge are discussed.     

Contemporary Educational Argumentation: A Multimodal Perspective

In contemporary educational contexts there is considerable variation in how argumentation works and what forms and styles it takes. Influencing factors include the educational purpose and task, the level of education, and the discipline or curriculum subject in which it occurs. This paper offers a theoretical framework and a set of multimodal analytical tools which can provide a rich and systematic account of such variation. Using naturalistic data from three different educational sites I illustrate how such a framework reveals the diverse ways in which students use language and other modes of meaning making as they engage in processes of argumentation. In particular, I consider how new technologies have caused shifts in the distribution of meaning across different semiotic modes (such as visual images, space, colour and graphics) and how this impacts upon both argumentation process and product. The educational implications of such changes are also considered.
