Etiological models of life-course persistent offending often emphasize behavioral explanations. Suggestions that persistent offenders have psychopathy ignore the distinct non-behavioral features of the psychopathy disorder. Using a three-factor model of the PCL-YV and cluster analysis with 259 incarcerated adolescents, we identified four distinct juvenile subtypes on the basis of affective, interpersonal, and behavioral dimensions. Prospective and retrospective comparisons of antisocial behavior patterns found the cluster comprising all three psychopathy dimensions to be the most chronic and severe. Impulsive features alone were strongly associated with severe antisocial behaviors retrospectively, but not prospectively. Findings rebut the proposal that disruptive behavioral and impulsive symptoms can identify "fledgling psychopaths." Assessments that disregard callous-unemotional traits will likely result in high false positive rates among serious adolescent offenders. Implications for developmental models of chronic offending are discussed in light of the need for further follow-up into adulthood. 相似文献

In the present study, the authors evaluated the self-concept levels of Hong Kong Chinese adults with visible and not visible physical disabilities. Fifty-five Hong Kong Chinese (22 men and 33 women) aged 18 to 55 (M = 39.50, SD = 10.21) participated-20 without physical disabilities (control group), 20 with visible physical disabilities, and 15 with physical disabilities that were not visible. All the participants responded to the Self-Concept Questionnaire for Hong Kong Chinese With Physical Disabilities (SCQPD; S. F. Tam & D. Watkins, 1997). The group with visible disabilities scored significantly lower in self-concept than did the control group and the group with disabilities that were not visible. There were also significant differences between specific facets of self-concept for people with visible and not visible disabilities. It was interesting to find that there was no significant difference in self-concept levels between the not visible group and the control group. The implications for rehabilitation and social services for these various groups are discussed. 相似文献

University of Saskatchewan, Saskatoon, Saskatchewan, Canada Models of deductive reasoning typically assume that reasoners
dedicate more logical analysis to unbelievable conclusions than to believable ones (e.g., Evans, Newstead, Allen, & Pollard,
1994; Newstead, Pollard, Evans, & Allen, 1992). When the conclusion is believable, reasoners are assumed to accept it without
much further thought, but when it is unbelievable, they are assumed to analyze the conclusion, presumably in an attempt to
disconfirm it. This disconfirmation hypothesis leads to two predictions, which were tested in the present experiment: Reasoners
should take longer to reason about problems leading to unbelievable conclusions, and reasoners should consider more models
or representations of premise information for unbelievable conclusions than for believable ones. Neither prediction was supported
by our data. Indeed, we observed that reasoners took significantly longer to reason about believable conclusions than about
unbelievable ones and generated the same number of representations regardless of the believability of the premises. We propose
a model, based on a modified version of verbal reasoning theory (Polk & Newell, 1995), that does not depend on the disconfirmation
assumption. 相似文献

Inhibition of return in children and adolescents 总被引:4,自引:0,他引:4
Inhibition of return (IOR), slowed responding to targets at a cued location after attention is removed from this location, has been shown to occur both in adults and in infants. To explore suggestion that the timecourse of IOR depends on factors that might affect the efficiency with which attention is removed from the cued location, we compared the performance of young children (5-10-year-olds, N=49, M=8 years, 4 months) to older children and adolescents (11-17-year-olds, N=61, M=14 years) in single and double cue procedures. Cue-target interval was varied to measure the timecourse of IOR in this within-subjects localization task. Whereas no IOR was found in the young group unless a double cue procedure was used, in the older group, we found IOR at all intervals with the double cue procedure and the typical crossover pattern, with early facilitation followed by inhibition in the single cue procedure. 相似文献

Research has shown that children often engage in gun play when they find a firearm and that this behavior is often involved in unintentional firearm injuries. Previous research has shown existing programs to be ineffective for teaching children safety skills to reduce gun play. This study examined the effectiveness of a behavioral skills training (BST) program supplemented with in situ training for teaching children safety skills to use when they find a gun (i.e., don't touch, leave the area, tell an adult). Eight 4- to 5-year-old children were trained and assessed in a naturalistic setting and in a generalized setting in a multiple baseline across subjects design. Results showed that 3 of the children performed the skills after receiving BST, whereas 5 of the children required supplemental in situ training. All children in the study learned to perform the skills when assessed in a naturalistic setting and when assessed in a generalization setting. Performance was maintained at 2- to 8-week follow-up assessments. 相似文献

In the present article, a commonly used meta-analytic procedure for handling dependent effect sizes from a single sample was examined, and 2 revised procedures that estimate and incorporate the degree of interdependence were proposed. The authors' simulation results reveal that the commonly used procedure that averages the effect sizes from a single sample (denoted as the samplewise procedure) underestimates the degree of heterogeneity. The proposed variations are less biased than the samplewise procedure in estimating the degree of heterogeneity in most of the situations that we examined. Future directions to further improve the procedures for handling dependent effect sizes from a single sample are discussed. 相似文献

We examined construct validity and implications of scales that assess perceived control over controllable events (realistic control belief) and perceived control over uncontrollable events (unrealistic control belief). We found that people high in unrealistic control belief are less likely to discriminate between controllable and uncontrollable situations and to distort task outcomes so as to make them appear more favorable (more under control). We also found that people high in realistic control belief are more likely to assume responsibility for past mistakes. In additional studies on coping and health risk behavior, higher realistic control belief was related to direct engagement with the stressor and to less risky sexual behavior; higher unrealistic control belief was related to less emotional processing and to more risky sexual behavior. The results demonstrate a need to discriminate between the two types of control beliefs. 相似文献

In this article, we present psychometric properties on the 14-item Harvey Imposter Phenomenon (IP) Scale (Harvey, 1981) among a sample of U.S. adolescents (N = 136). Item analyses, internal consistency reliability, and principal components analysis (PCA) were computed to assess the reliability and factor structure of the IP scores. Although the internal consistency reliability (e.g., Cronbach's alpha) was reasonably acceptable (alpha =.70), the item analyses and subsequent PCA suggest concern for the content homogeneity and factor structure of composite scores obtained from the 14-item measure. The results of this study suggest that the indiscriminate use of the Harvey IP Scale is cautioned relative to the insufficient psychometric properties. 相似文献

The role of attributional retraining and elaborative learning in college students' academic development 总被引:1,自引:0,他引:1
In the present longitudinal study, the authors examined the impact of attributional retraining (AR) techniques on academic motivation and achievement for college students who are either frequently or infrequently using elaborative learning strategies. During the 1st semester, 203 students completed an initial questionnaire assessing elaborative learning followed by 1 of 3 treatment conditions (No AR, Writing AR, Aptitude Test AR). Results indicated improvements in students' end-of-year perceptions of control, success, and emotions, as well as course-specific and overall academic performance for those receiving either AR format, with "high elaborators" showing higher levels on these measures than "low elaborators." The authors discussed the importance of elaborative and attributional processes underlying the effectiveness of the AR treatment and the potential utility of individualized AR techniques in the college classroom. 相似文献
