People with Williams syndrome process faces holistically

This study compared the performance of 47 adolescents and adults with Williams syndrome to 39 age-matched controls on a face recognition task. Using the whole-part paradigm developed by Tanaka and his colleagues, we found that although performance overall was lower in the participants with Williams syndrome, both groups showed similar patterns of performance across the different conditions. Both groups performed significantly better in the whole-face than in the isolated-part test condition for upright faces, but not for inverted faces. The whole-face advantage only in the upright condition provides strong evidence that people with Williams syndrome encode and recognize faces holistically in the same way as normal controls, suggesting the use of similar underlying neurocognitive mechanisms. These findings contradict earlier reports in the literature that people with Williams syndrome process faces abnormally.     

Functional imaging of 'theory of mind'

Our ability to explain and predict other people's behaviour by attributing to them independent mental states, such as beliefs and desires, is known as having a 'theory of mind'. Interest in this very human ability has engendered a growing body of evidence concerning its evolution and development and the biological basis of the mechanisms underpinning it. Functional imaging has played a key role in seeking to isolate brain regions specific to this ability. Three areas are consistently activated in association with theory of mind. These are the anterior paracingulate cortex, the superior temporal sulci and the temporal poles bilaterally. This review discusses the functional significance of each of these areas within a social cognitive network.     

The Long-Term Neurocognitive Consequences of Prenatal Alcohol Exposure: A 14-Year Study

Prenatal alcohol exposure, at doses not generally associated with maternal alcohol problems, produces a broad array of neurocognitive deficits in offspring even in the absence of effects on growth and morphology. This report presents a summary of neurobehavioral, growth, and morphology findings from long-term follow-up of a birth cohort of 500 from apopulation-based study that has revealed attention, memory, and information processing deficits from birth through 14 years. Also observed (from school age through 14 years) have been problems with antisocial and delinquent behaviors, and classroom learning and behaviors; some of these problems may be secondary to earlier neurocognitive disabilities. Continuing research in behavioral and neurobehavioral teratology provides important opportunities for the neurosciences and for improved health of future generations.     

Charpentier (1891) on the size—weight illusion

This paper offers background for an English translation of an article originally published in 1891 by Augustin Charpentier (1852–1916), as well as a summary of it. The article is frequently described as providing the first experimental evidence for the size—weight illusion. A comparison of experiments on the judged heaviness of lifted weights carried out by Weber (1834) and by Charpentier (1891) supports the view that Charpentiers work deserves priority; review of other experimental studies on the size-weight illusion in the 1890s suggests that the idea that the illusion depended on “disappointed expectations,” especially with respect to speed of lift, became dominant almost immediately following the publication of Charpentiers paper. The fate of this and other ideas, including “motor energy,” in 20th-century research on the illusion is briefly described.     

The Utility of the Revised Life Orientation Test to Measure Optimism among Hong Kong Chinese

To examine the utility of the revised Life Orientation Test (LOT-R) to measure optimism among Hong Kong Chinese, the psychometric properties of the revised and the original versions of the Life Orientation Test were compared. A total of 248 Hong Kong Chinese undergraduates were studied in the fall and 165 of these participants were tested again 5 months later. Results indicated that the LOT-R is a reliable and valid measure of dispositional optimism among Hong Kong Chinese. Confirmatory factor analysis showed that the LOT-R represents a one-factor model of optimism better than does the original version. Despite its brevity, the LOT-R is psychometrically sounder than the original sclae. These findings point to the feasibility of replacing the original with the revised scale in future research among Hong Kong Chinese. However, the utility of the revised test in cross-cultural comparisons may still be limited by the absence of emic components. Further research on optimism in the Chinese people with the LOT-R should pay more attention to the identification of emic dimensions.     

Ethnic Minority Psychologists: Whom They Mentor and Benefits They Derive From the Process

Ethnic minority psychologists were found to be prolific mentors of both ethnic minority and European American protégés. Mentoring benefits were not related to ethnic similarity.     

Vasopressin,glucose homeostasis,and sucrose taste preferences

Previous research indicates that vasopressin-containing (LE) rats are capable of adapting to the stress of food restriction, whereas vasopressin-deficient (DI) rats cannot adapt to this stressor. It has been postulated that abnormalities in glucose metabolism may be one of the factors leading to the demise of food-restricted DI rats. The present study was conducted to determine if taste preferences are altered in DI animals and if the presentation of exogenous glucose, in the form of sucrose solutions, can ameliorate the effects of the stress of food restriction. Four different concentrations of sucrose solutions were presented to LE and DI rats under the food-restricted condition. In both strains, an 8% sucrose solution was preferred over 0%, 16%, and 32% concentrations, with DI rats consuming more of this concentration than LE rats. Thus, when DI rats had the opportunity of maintaining glucose homeostasis by exogenous supplements, they maintained body weight, displayed no stomach pathology, and survived.     

Self-consciousness,evaluation of physical characteristics,and physical attractiveness

Results from an investigation of the relationship between habitual awareness of oneself as a social object (Public self-consciousness) and speed of processing information about the overt self are reported. Since high public self-consciousness subjects report themselves to be concerned about their physical appearance, they were expected to have more readily retrievable evaluative judgments concerning their physical characteristics. Consistent with this prediction, high compared to low public consciousness subjects required significantly less time to report their evaluations of eleven of their physical features. In a second study, high public self-consciousness was shown to be positively related to judged physical attractiveness in two geographically diverse samples. The quicker evaluations of the high public self-consciousness group were discussed in terms of information processing model recently described by Markus (1977).     

Gender differences in attributions for triathlon performance

Causal attributions given by athletes for performance can influence performance satisfaction, expectation of future success, and persistence in training and competition. Young and inexperienced athletes often show gender differences in sport attribution, with males attributing success to controllable or stable factors like ability and effort, and females attributing success to uncontrollable or unstable factors like luck and social support. Would older, more experienced female triathletes also show a self-defeating attribution style and see themselves with little control over sport performance? Using questionnaires, 624 triathletes (mostly white, 443 males, 181 females) rated the importance of 13 attributions for triathlon performance. Unlike past research, female triathletes attributed more importance than males to factors they can attempt to control (psychological state, diet, and weight). After a recent success, female triathletes downplayed the importance of luck and social support.
