The article first summarizes the assumptions of Luce (2004, 2008) for inherently binary (2-D) stimuli (e.g., the ears and eyes) that lead to a "p-additive," order-preserving psychophysical representation. Next, a somewhat parallel theory for unary (1-D) signals is developed for intensity attributes such as linear extent, vibration to finger, and…

Theory of Mind, Weak Central Coherence and executive dysfunction, were investigated as a function of behavioural markers of autism. This was irrespective of the presence or absence of a diagnosis of an autistic spectrum disorder. Sixty young people completed the Social Communication Questionnaire (SCQ), false belief tests, the block design test,…

Recent studies show that powerlessness is an important variable in predicting behavioral and attitudinal patterns, and is related to environmental factors. (DM)

Individuals interacting with an unfamiliar target person behave according to prior impressions of the target. A perceiver's pre-interaction expectancy can mediate both his and the target person's behavior, resulting in behavioral confirmation or compensation. Male subjects (N=96) participated in dyadic interactions in which one subject (perceiver)…

Current literature suggests that a teacher's expectancies for a pupil may in part determine the pupil's subsequent behavior. This review asks how such expectancies affect the teacher's own behavior, with the goal of determining what teacher behaviors mediate the observed effect on the pupil. A model of this process is proposed. (Author)

The effects of observational purpose are thought to impact on such diverse processes as categorization, behavior perception, trait ascription, and memory. The role of observational purpose in the categorization of behavior was explored to determine whether differences between trait and goal concepts affect certain information-processing…
