Varieties of grapheme-colour synaesthesia: a new theory of phenomenological and behavioural differences

Recent research has suggested that not all grapheme-colour synaesthetes are alike. One suggestion is that they can be divided, phenomenologically, in terms of whether the colours are experienced in external or internal space (projector–associator distinction). Another suggestion is that they can be divided according to whether it is the perceptual or conceptual attributes of a stimulus that is critical (higher–lower distinction). This study compares the behavioural performance of 7 projector and 7 associator synaesthetes. We demonstrate that this distinction does not map on to behavioural traits expected from the higher–lower distinction. We replicate previous research showing that projectors are faster at naming their synaesthetic colours than veridical colours, and that associators show the reverse profile. Synaesthetes who project colours into external space but not on to the surface of the grapheme behave like associators on this task. In a second task, graphemes presented briefly in the periphery are more likely to elicit reports of colour in projectors than associators, but the colours only tend to be accurate when the grapheme itself is also accurately identified. We propose an alternative model of individual differences in grapheme-colour synaesthesia that emphasises the role of different spatial reference frames in synaesthetic perception. In doing so, we attempt to bring the synaesthesia literature closer to current models of non-synaesthetic perception, attention and binding.     

Psychosocial Functioning in Children and Adolescents with Extreme Obesity

The aim of this study was to investigate the psychosocial differences among obese pediatric patients, particularly those who are "extremely obese" as compared to "obese." Information was collected for 249 subjects at a multidisciplinary treatment clinic for obese youth. A battery of measures was administered and demographic data and height/weight was obtained. The results showed positive correlations between degree of obesity, psychosocial functioning, and quality of life. Specifically, the "extremely obese" were significantly more depressed, more socially anxious, and had poorer quality of life than the "obese" group. Girls and Caucasians were more socially anxious than boys and African Americans, respectively. There is mounting evidence that children and adolescents who are extremely obese are most at risk for psychiatric and medical disorders. Thus, targeting this group for assessment and/or designing treatment options specific for "extremely obese" youth is critical for the successful management of this population.     

Capturing the Naturally Occurring Superior Performance of Experts in the Laboratory: Toward a Science of Expert and Exceptional Performance

ABSTRACT— Expertise researchers have traditionally shied away from studying the highest levels of achievement in favor of studying basic cognitive processes, such as memory and categorization. In this article, we present a different approach that is focused on capturing superior (expert) performance on representative tasks that reveal the essential characteristics of expertise in a given domain. In domains where expert performance is measurable, acquisition is gradual and the highest levels are only attained after 10 years of intense preparation—even for the most "talented." Analyses of reproducibly superior performance show that it is mediated by physiological adaptations and cognitive skills acquired as a result of the cumulative effects of special practice activities (deliberate practice). It appears that the genes necessary to attain such adaptations and expert skills can be activated in healthy children—the only clear exceptions to date being genes that control body size and height. Our knowledge of how experts acquire their superior skills provides insights into the potential for human adaptation and skill acquisition and has important implications for theories of the structure of general and expert cognition, as well as for training interventions in applied psychology and education.     

Perceptual‐cognitive expertise in sport and its acquisition: Implications for applied cognitive psychology

We review contemporary research on perceptual‐cognitive expertise in sport and consider implications for those working in the field of applied cognitive psychology. We identify the important perceptual‐cognitive skills that facilitate anticipation in sport and illustrate how these skills interact in a dynamic manner during performance. We also highlight our current understanding of how these skills are acquired and consider the extent to which the underlying processes are specific to a particular domain and role within that domain. Next, we briefly review recent attempts to facilitate the acquisition of perceptual‐cognitive expertise using simulation training coupled with instruction and feedback on task performance. Finally, we discuss how research on elite athletes can help inform applied cognitive psychologists who are interested in capturing and enhancing perceptual‐cognitive expertise across various domains.

Repeated Auditory Stimulation of the Startle Response in the Guinea Pig

Simulated and behavioral personal space measures and the Sensation Seeking Scale were administered to 20 males and 20 females. In the simulated measures Ss positioned male and female top profiles relative to a top profile representing themselves at each of nine equally spaced angles. For the behavioral measure Ss were approached by a male or female at each of the nine angles.

The female “swinger” had greater simulated personal space. Males who liked new and interesting experiences had greater side and diagonal simulated personal space, and females high on the same scale had a closer behavioral personal space toward males except at the sides. Males and females responded similarly to males and females approaching from various directions. However, there was no relation between front and side simulated personal space for males. Size of personal space relative to females tended to be highly correlated with size of personal space toward males. However, for male Ss there was little relation between front personal space toward males and females. For male Ss simulated personal space and behavioral personal space were highly correlated. For female Ss the two measures were almost completely unrelated.     

School desegregation and social science research

Research on the effects of school desegregation, once quite common in psychology and related fields, has declined considerably since the mid-1980s. Factors contributing to changes in the quantity and focus of such research since the Brown v. Board of Education (1954) decision are discussed, with an emphasis on those related to the decline of this research in the last 2 decades. These factors include the nation's retreat from the policy of school desegregation and the associated decline in research funding. Changing perspectives regarding desegregation, the outcomes of desegregation that merit study, and the desirable composition of research teams studying desegregation have also played a role. Demographic changes in our society and its schools that have made salient other research topics and the development of effective research paradigms for studying intergroup relations in the laboratory have also contributed to this decline.

To eat or not to eat: implications of the attentional myopia model for restrained eaters

The attentional myopia model of behavioral control was tested in a study of food consumption by chronic dieters. According to the model, when individuals' attentional capacity is limited, their behavior will be disproportionately influenced by highly salient internal and external cues to the exclusion of more distal stimuli. In situations that normally feature conflicting behavioral pressures, such a state of narrowed attention is likely to result in abnormally disinhibited behavior when cues promoting action are more salient and to result in abnormally restrained behavior when inhibiting cues are more salient. In addition to supporting the predictions of the model, this study provided the first evidence for enhanced behavioral control under conditions of limited attention. Participants' responses to a thought-reporting measure also provided evidence for the role played by attentional myopia in the control of eating. Implications for a broad array of regulatory successes and failures are discussed.     

Behavioral interventions to improve performance in collegiate football

Using a multitreatment withdrawal design, this study evaluated the differential effects of publicly posted plus verbal feedback, goal setting plus verbal feedback, and publicly posted feedback, verbal feedback, and goal setting together on the performance of 3 collegiate football players in practice scrimmages. Also assessed was whether the changes in practice behavior generalized to games. The dependent variables were performances on three wide receiver skills. The results show that public posting with verbal feedback, goal setting, and public posting with verbal feedback and goal setting were effective in improving player performance to a 90% criterion level during practice, and these changes generalized to game performance.
