The effects of isolation and handling on the reactivity of rats to two tactile stimuli were assessed in two experiments. In the first experiment, reactivity to more intense footshock was increased in rats raised in isolation but was not affected by handling by an experimenter. In the second experiment, increased reactivity to airpuff stimuli presented to the dorsal surface of isolation-reared rats was reduced by handling. The data suggest that the effects of handling on shock-motivated behaviors are not due to altered reactivity to shock and that the effect of housing or handling must be considered in behavioral tests in which reactivity to tactile stimulation might play a role as dependent or independent variables. 相似文献

OBJECTIVE: The primary goal of the present research was to determine whether retrospective reports of childhood disciplinary experiences and perceptions of that discipline correspond to actual childhood events and whether the accuracy of that report was influenced by the affective state of the respondent. METHOD: Eighty-three adolescent and young adult males completed a retrospective measure of physical child maltreatment, Assessing Environments (AEIII), and the Brief Symptom Inventory (BSI). As children the participants had been observed naturalistically in their homes interacting with their parents an average of 10 years earlier. RESULTS: Analyses were consistent with the hypothesis that both current mood and actual observations of parent-child interactions during childhood predict self-reported recollections of childhood maltreatment by one's parents. Further the veridicality of such recollections appears to depend upon the objective specificity versus the perceptive nature of the questions used to elicit the recollections. CONCLUSIONS: The findings suggest that assessment instruments suitable for obtaining information regarding earlier childhood victimization must utilize behaviorally specific items. Thus, items that are either global or intimate a normative comparison should be avoided. 相似文献

Abstract The Learning Science in Informal Environments report holds great potential for creating change among those who work in the field of science education. But to what extent can it inform other sectors of the informal education world? This article explores how the LSIE report might influence research and practice in art museums. By comparing the report to a recent study in art education, the authors point out areas of overlap and divergence relative to content and skills, identity, and communities of practice. We suggest several implications for how art museums and science museums might learn from one another. A call to action is made for further research and discussion about common learning goals and outcomes for the art museum experience. 相似文献

This article presents an exploratory study of the relation between academic engagement and academic achievement for Latina/o and non-Latina/o adolescents attending a predominantly low-income, Latina/o urban middle school in Southern California. A sample of 61 students (37 Latinas/os and 24 non-Latinas/os) participated in the study. The Latina/o students’ mean grade point average was lower than the non-Latina/o students’ mean grade point average. The study results revealed a significant interaction between academic engagement and grade point average for Latina/o students but not for non-Latina/o students. Findings are discussed in regard to the promotion of Latina/o adolescent achievement through increased levels of academic engagement. 相似文献

OBJECTIVE: To assess the disciplinary preferences of mothers of profoundly deaf children and normally hearing children in a test of the hypothesized link between child disabilities and punitive parenting. METHOD: Disciplinary preferences of mothers seeking a cochlear implant for their profoundly deaf child (n=57), mothers not seeking an implant for their deaf child (n=22), and mothers of normally hearing children (n=27) were assessed using an analog task in which subjects select discipline in response to slide images of children engaging in normative or frankly deviant behaviors that are potentially irritating. RESULTS: Results indicated that mothers of children with profound hearing impairments were more likely to select physical discipline in response to depicted child transgressions and more likely to escalate to physical discipline when the depicted child was described as persisting in the transgression. Additionally, escalation was more probable in response to scenes depicting children engaged in dangerous and destructive acts than in rule-violating acts. CONCLUSIONS: Findings were consistent with the hypothesized link between childhood disabilities and child maltreatment as well as the hypothesis that children with disabilities associated with communication problems could be at risk of physical abuse. 相似文献

This study was conducted to assess the maintenance of operant responding in the presence of free access to the reinforcer. The results replicated earlier research using food reinforcement and demonstrated that the same general results could be obtained with water reinforcement. 相似文献
