The question asked in this study of 70 clinically referred 6- to 12-year-old boys with behavior problems was whether or not childhood inattention-overactivity and aggression are transmitted specifically from biological fathers to sons. Fathers' self-reported childhood inattention-overactivity on a retrospectively valid measure was exclusively associated with parents' ratings of their sons' current attention problems on the Mothers' Operational Measure for Sub-grouping (MOMS), the Revised Child Behavior Checklist (RCBCL), and an approximated DSM-IV inattention dimension. Fathers' self-reported childhood aggression was not associated with ratings of their sons' aggression on the MOMS or DADS (a parallel instrument for fathers), nor on DSM-III oppositional or conduct disorder dimensions, but it was exclusively associated with RCBCL ratings of sons' aggressive and delinquent behavior. None of the nonspecific correlations (father inattention-overactivity with son aggression or father aggression with son inattention-overactivity) was significant. 相似文献

“Are False Memories Permanent?”: An Investigation of the Long-Term Effects of Source Misattributions
With growing concerns over children's suggestibility and how it may impact their reliability as witnesses, there is increasing interest in determining the long-term effects of induced memories. The goal of the present research was to learn whether source misattributions found by Ceci, Huffman, Smith, and Loftus (1994) caused permanent memory alterations in the subjects tested. When 22 children from the original study were reinterviewed 2 years later, they recalled 77% of all true events. However, they only consented to 13% of all false events, compared to the 22% false consent rate (among the same subset of children) found by Ceci et al. (1994). Additionally, while children remained accurate in their recall of true events (they maintained assents 78% of the time), they “recanted” their earlier false consents 77% of the time, after the 2-year delay. Implications of these findings for child witnesses and the legal system are discussed. 相似文献

Gender and Self-Reported Sexual Arousal in Response to Sexual Stimuli: A Meta-Analytic Review 总被引:3,自引:0,他引:3
Social constructionist theories and sociobiological perspectives have led to increased interest in gender differences in sexual behavior. This study involved a meta-analysis of gender differences in sexual arousal in response to sexual stimuli. Forty-six studies in which participants were presented with a sexual stimulus depicting males and females and in which participants responded using a self-report measure of arousal were compiled, and 62 independent effect sizes were aggregated. An overall effect size of d = .31 showed a small to moderate-sized gender difference in sexual arousal with men reporting more arousal than women across all studies. There was significant variation in the effect sizes, though, which was only partially explained by variables coded from the studies. It was found that the gender difference was slightly larger for studies using pornographic vs. erotic stimuli, was larger for studies where participants were tested in a private setting or small group compared to a large group, and was much larger for college age participants compared to those who were older than college age. Generally, the pattern of results provided more support for predictions from social influence theories compared to sociobiological theory. 相似文献

Assessment center validity data from a large, international petrochemical company were disaggregated by managerial level and business stream. As with previous research, the correlations were higher for the current job grade criterion than for performance ratings. Overall, disaggregating the data did not have the effect of increasing the assessment center—performance rating validities. However, when the validation data were disaggregated by business stream, there were differences in the pattern of the relationships between assessment factors and performance. 相似文献

Abstract— The apparent brightness of a surface is profoundly influenced by the brightness of an adjacent surface., but these contrast effects are reduced when the surface are perceived as separate three-dimensional entities. Previous work has suggested that high-level perceptual and cognitive processes involved in scence segmentation may be responsible for modifying a surface's appearance. We demonstrate large reductions in contrast effects when the sues available for segmentations are restricted to those that isolate separate groups of early cortical neurons in the visual system. Our data contradict standard contract-signaling models of brightness perception and imply that mechanisms of figure-ground segmentation are already available at low levels of visual processing. 相似文献

The seminar group can serve as a framework in which to meet the fear generated during training. The group can become a maddening environment, but on occasions when it is experienced by the trainee as good enough, it can act like a playgroup which facilitates development. Experiences in the group can be viewed from the perspectives of group dynamics or of transference phenomena which embody regression. When this regression enables scope for play it can serve in the interests of ego development in the process of discovering the sort of analyst the trainee is becoming as the training unfolds. During play aspects of oneself can merge, then differentiate again. They can have different meanings at the same time. The rational and emotional, the adult and the childlike are all given a place in play. 相似文献

Mechanical restraints are commonly used to reduce the risks associated with severe self-injurious behavior (SIB), but may result in movement restriction and adverse side effects (e.g., bone demineralization). Restraint fading may provide a method for decreasing SIB while increasing movement and reducing these side effects. In the current investigation, rigid arm sleeves and restraint fading (gradually reducing the rigidity of the sleeves) were used with 3 clients who engaged in hand-to-head SIB. Restraints and fading reduced the hand-to-head SIB of all clients. However, for 1 client, the addition of a water mist procedure further reduced SIB to near-zero levels. For a 2nd client, another form of SIB developed that was not prevented by the rigid sleeves. For a 3rd client, a topography of SIB that was not physically prevented by the rigid sleeves was also reduced when restraints and fading were introduced. 相似文献

High-probability requests were used to increase social interactions in 3 young boys with severe disabilities who had been identified as severely socially withdrawn. A multiple baseline design across participants was used to evaluate the effects of high-probability request intervention on (a) social initiations, (b) social responses, (c) continued interactions, and (d) performance of high- and low-probability requests. The students were observed in a second setting to examine generalization effects across peers who did not participate in the training sequence and settings. The results demonstrated that the high-probability requests increased the students' responsiveness to low-probability requests to initiate social behavior. Increases were also found in (a) unprompted initiations and extended interactions to the training peers, (b) unprompted initiations and extended interactions to peers who were not involved in the training procedure, and (c) generalized unprompted initiations and interactions in a second nontraining setting. The students maintained increased levels of initiations and interactions after all prompts were removed from both the training and nontraining settings. 相似文献

The purpose of this study was to identify ethnic and gender differences in the types of information Anglo and Hispanic exercisers use in self-evaluation. University students in exercise classes rated the importance of norm-referenced and self-referenced sources used in self-evaluation of performance. Results showed that males rated norm-referenced sources as more important to self-evaluation, while females rated self-referenced sources as most important. A gender by ethnicity interaction showed that Anglos, especially Anglo males, preferred norm-referenced sources, while Hispanics preferred self-referenced sources. Provided with this information, instructors could more effectively motivate exercise participants. 相似文献
