Theories of autism have proposed that a bias towards low-level perceptual information, or a featural/surface-biased information-processing style, may compromise higher-level language processing in such individuals. Two experiments, utilizing linguistic stimuli with competing low-level/perceptual and high-level/semantic information, tested processing biases in children with autism and matched controls. Whereas children with autism exhibited superior perceptual processing of speech relative to controls, and showed no evidence of either a perceptual or semantic processing bias, controls showed a tendency to process speech semantically. The data provide partial support to the perceptual theories of autism. It is additionally proposed that the pattern of results may reflect different patterns of attentional focusing towards single or multiple stimulus cues in speech between children with autism and controls. 相似文献

Morningness/eveningness, morning-to-afternoon cortisol ratio, and antisocial behavior problems during puberty 总被引:1,自引:0,他引:1

The relationship between morningness/eveningness (M/E) and morning-to-afternoon cortisol ratio, pubertal timing, and antisocial behavior was examined in 111 girls and boys ages 8 to 13 years. Cortisol levels showed a significant increase after awakening and declined thereafter (p<.05). Eveningness was related to a composite measure of antisocial behavior and rule-breaking and attention behavior problems and conduct disorder (CD) symptoms in boys and relational aggression in girls. In boys only, lower a.m. to p.m. cortisol ratio, indicating less circadian decrease in cortisol, was related to attention problems. Early pubertal timing was associated with boys' rule-breaking and attention behavior problems and CD symptoms and girls' relational aggression. The findings indicate that evening activity preference; extreme a.m. to p.m. cortisol ratios, in one case; and early pubertal timing were associated with antisocial behavior even in young adolescents, but the findings were stronger for boys than for girls. 相似文献

This study examined psychological and physical health factors in a cohort of U.S. Marine recruits with the goal of developing a comprehensive understanding of attributes recruits bring to training. 1,350 male recruits completed a multimeasure survey during the first week of training. A 2-way multivariate analysis of variance (MANOVA) was conducted to explore the relationship of hardiness dimensions on several psychological and physical factors. Compared with other military samples, this cohort reported similar levels on hardiness control and rigidity subscales. Recruits who reported higher scores on a measure of positive hardiness also reported higher scores on measures of grit, grit ambition, sensation seeking, training expectations, positive ways of coping, physical and mental health, fitness scores, and lower scores on a measure of depression. This study provides a more complete understanding of the complex array of attributes of Marine recruits and forms a foundation for predictive models of injury risk and/or attrition. 相似文献

Developmental change and cross‐domain links in vocal and musical emotion recognition performance in childhood 下载免费PDF全文
Although the configurations of psychoacoustic cues signalling emotions in human vocalizations and instrumental music are very similar, cross‐domain links in recognition performance have yet to be studied developmentally. Two hundred and twenty 5‐ to 10‐year‐old children were asked to identify musical excerpts and vocalizations as happy, sad, or fearful. The results revealed age‐related increases in overall recognition performance with significant correlations across vocal and musical conditions at all developmental stages. Recognition scores were greater for musical than vocal stimuli and were superior in females compared with males. These results confirm that recognition of emotions in vocal and musical stimuli is linked by 5 years and that sensitivity to emotions in auditory stimuli is influenced by age and gender. 相似文献
