Recent studies have shown associations between maternal psychopathology and inhibited behaviors in infants. Moreover, physiological factors have been identified as affecting the continuity of behavioral inhibition across childhood. The purpose of the present study was to examine electroencephalogram (EEG) activity and inhibited behavior in 12-month-old infants of depressed versus non-depressed and mothers. Repeated measures MANOVAs indicated that the infants of mothers with stable psychopathology had greater relative right frontal EEG asymmetry, a pattern that typically accompanies greater negative affect and greater withdrawal behaviors. Infants of affectively ill mothers also showed more proximal behaviors toward a stranger and a novel toy than infants of well mothers, but fewer non-proximal behaviors toward their mothers. These results are discussed within a framework of behavioral inhibition for infants exposed to early psychopathologies in their mothers. 相似文献

Using the classical twin design, this study investigates the influence of genetic factors on the large phenotypic variance in inspection time (IT), and whether the well established IT–IQ association can be explained by a common genetic factor. Three hundred ninety pairs of twins (184 monozygotic, MZ; 206 dizygotic, DZ) with a mean age of 16 years participated, and 49 pairs returned approximately 3 months later for retesting. As in many IT studies, the pi figure stimulus was used and IT was estimated from the cumulative normal ogive. IT ranged from 39.4 to 774.1 ms (159±110.1 ms) with faster ITs (by an average of 26.9 ms) found in the retest session from which a reliability of .69 was estimated. Full-scale IQ (FIQ) was assessed by the Multidimensional Aptitude Battery (MAB) and ranged from 79 to 145 (111±13). The phenotypic association between IT and FIQ was confirmed (−.35) and bivariate results showed that a common genetic factor accounted for 36% of the variance in IT and 32% of the variance in FIQ. The maximum likelihood estimate of the genetic correlation was −.63. When performance and verbal IQ (PIQ & VIQ) were analysed with IT, a stronger phenotypic and genetic relationship was found between PIQ and IT than with VIQ. A large part of the IT variance (64%) was accounted for by a unique environmental factor. Further genetic factors were needed to explain the remaining variance in IQ with a small component of unique environmental variance present. The separability of a shared genetic factor influencing IT and IQ from the total genetic variance in IQ suggests that IT affects a specific subcomponent of intelligence rather than a generalised efficiency. 相似文献

This study evaluated peer incidental teaching as a strategy for increasing reciprocal peer interactions by children with autism. Three typical preschoolers were trained as peer tutors for 3 young children with autism. During a classroom free-play session, peer tutors used incidental teaching to obtain verbal labels of preferred toys by children with autism. A multiple baseline across the 3 target children showed replicated positive effects of the intervention. Adult supervision and assistance were then faded systematically, with resulting maintenance of increased reciprocal interactions. Multiple measures of the extent and limits of generalization suggested that 1 child increased interactions in free-play periods throughout the day, but none of the children showed increases at lunch. Teacher and peer ratings supported the social validity of positive findings. 相似文献

Archival data were collected to examine bias effects in performance evaluation related to employee pregnancy. Prior survey research has suggested that many supervisors and co-workers hold negative views of pregnant employees. Performance appraisal ratings were collected before, during, and after pregnancy for employees taking maternity leave over a four year time frame. In addition, data was also collected from randomly selected control subjects, which were matched on job title and observation period. Contrary to expectations, performance appraisal ratings were found to increase during pregnancy when compared to before ratings and control group ratings. Potential explanations as well as suggestions for further research are discussed. 相似文献

The study investigated interpretive understanding, moral judgments, and emotion attributions in relation to social behaviour in a sample of 59 5‐year‐old, 123 7‐year‐old, and 130 9‐year‐old children. Interpretive understanding was assessed by two tasks measuring children's understanding of ambiguous situations. Moral judgments and emotion attributions were measured using two moral rule transgressions. Social behaviour was assessed using teachers' ratings of aggressive and prosocial behaviour. Aggressive behaviour was positively related to interpretive understanding and negatively related to moral reasoning. Prosocial behaviour was positively associated with attribution of fear. Moral judgments and emotion attributions were related, depending on age. Interpretive understanding was unrelated to moral judgments and emotion attributions. The findings are discussed in regard to the role of interpretive understanding and moral and affective knowledge in understanding children's social behaviour. 相似文献

A forced-choice preference assessment using pictures and no access upon selection was used to determine preferences for community-based activities with 4 young adults with autism and intellectual disability. High- and low-preference activities were then provided as delayed consequences, using a token economy, for completion of vocational tasks in a concurrent operants paradigm. All participants responded to the contingency associated with earning the high-preference activity and away from the contingency associated with earning the low-preference activity. The results suggest that a pictorial assessment without access is a valid method for identifying community-based activities that will function as reinforcers. This efficient protocol could improve treatment efficacy in applied settings. 相似文献
