This study examined the relation of motivational systems to patterns of autonomic responses to stress. Specifically, we examined patterns of physiological response resulting from differential activation of motivational systems for behavioral approach and behavioral inhibition. We also examined the relation of these motivational systems to threat and challenge responses to potential stress. Self-report, cardiac measures (i.e., pre-injection period, or PEP, and heart rate, or HR), and blood pressure (i.e., systolic blood pressure, or SBP, and diastolic blood pressure, or DBP) measures reliably distinguished between an experimental condition facilitating behavioral approach and an experimental condition facilitating coactivation of behavioral approach and behavioral inhibition systems. Vascular (e.g., total peripheral resistance, or TPR) and electrodermal (e.g., electrodermal response, or EDR) measures, however, did not vary by condition. We discuss the results in relation to other research on motivational factors as they relate to stress and cardiovascular reactivity.  相似文献

A total of 229 late adolescents (a large majority 15 to 19 years of age) completed a questionnaire that assesses a broad range of videogame-relevant experiences, preferences, and attitudes. Videogame playing was found to be a more popular, and a more highly regarded, activity among males than females. Gender differences were also found in participants' ratings of their motivations for playing videogames, their evaluations of particular characteristics of videogames, and their selection of their “most favorite” videogame. The differences between frequent and infrequent videogame players appeared to be limited to differences in the extent to which videogame playing is pursued and evaluated as a positive leisure activity, rather than reflecting broad differences in interest or personality. Some relations were found between participants' self-reported personality characteristics (i.e., self-esteem, empathy, conscientiousness, and introversion) and their attitudes toward videogames.  相似文献

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

Previous research has revealed that English-speaking preschoolers expect that a novel count noun (but not a novel adjective), applied to an individual object, may be extended to other members of the same basic or superordinate level category. However, because the existing literature is based almost exclusively on English-speakers, it is unclear whether this specific expectation is evident in children acquiring languages other than English. The experiments reported here constitute the first cross-linguistic, developmental test of the noun-category linkage. We examined monolingual French- and Spanish-speaking preschool-aged children's superordinate level categorization in a match-to-sample task. Target objects were introduced with (a) novel words presented as count nouns (e.g., “This is afopin”), (b) novel words presented as adjectives (e.g., “This is afopishone”), or (c) no novel words. Like English-speakers, French- and Spanish-speakers extended count nouns consistently to other category members. This is consistent with our prediction that the mapping between count nouns and object categories may be a universal phenomenon. However, children's extension of novel adjectives varied across languages. Like English-speakers, French-speakers did not extend novel adjectives to other members of the same category. In contrast, Spanish-speakers did extend novel adjectives, like count nouns, in this fashion. This is consistent with our prediction that the mappings between adjectives and their associated applications vary across languages. The results provide much-needed cross-linguistic support for the noun-category linkage and illustrate the importance of the interplay between constraints within the child and input from the language environment.  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

Performance self-predictions represent an individual's anticipated level performance on an upcoming task. This study focused on the accuracy of these predictions, as well as subjective reactions to making them under varying expectancy and incentive conditions. Results indicate that performance-contingent incentives had a positive effect on task performance, but a negative effect on preferences for making performance predictions. Expectancy strength also influenced these predictions, their subjective interpretations, and task performance. Additional results address the role of other task-relevant judgments (e.g., self-assessed ability and intended effort) when predicting one's performance on a task. Implications of these findings for work motivation and judgment accuracy are discussed.  相似文献

ABSTRACT In this study, we examined the construct of the imaginary audience (Elkind & Bowen, 1979), presumably a precipitant of adolescent egocentrism, as it relates to public individuation and self-consciousness. We hypothesized that the imaginary audience inhibits public individuation and represents a critical form of public self-consciousness. We also argued that the imaginary audience is a normal aspect of early adolescent development that diminishes in the context of secure parental relationships by late adolescence but remains salient if these relationships are insecure. These hypotheses were examined in a cross-sectional study of 850 adolescents in the 7th, 8th, 9th, and 12th grades. Support was generally found for the hypothesized relations. The validity and limitations of the imaginary audience and public individuation constructs are discussed, along with more general theoretical issues concerning adolescent self-consciousness.  相似文献

Understanding the mental processes involved in suffering has always been the best basis for communication between patients and caretakers. In this paper we are concerned first with acknowledgment of the existence, generally unknown, and the effects, generally unrecognized, of the hypnotic processes that occur in many forms of suffering, and second with developing our thesis that the understanding and use of hypnotic principles can greatly enrich the chaplain's capacity to alleviate suffering. In this brief presentation we will confine our discussion to the teaching of hypnosis as a virtual necessity in modern clinical training for chaplains. Comments and considerations will precede and follow an outline of the course presently offered at Lenox Hill Hospital [but we cannot here attempt to discuss or explain the fundamentals of hypnotic process or any other aspects of the course content itself]. A basic bibliography is appended for those who wish to know more about hypnosis itself.  相似文献

Hoarding behavior, patterns of use of possessions, and emotional attachment to possessions were examined among a sample of female undergraduates and a sample of community volunteers. Hoarding behavior was associated with a decreased frequency of use of possessions and excessive concern about maintaining control over possessions. Furthermore, high scores on the hoarding scale were associated with higher levels of perceived responsibility for: (1) being prepared; and (2) the well-being of the possession. Hoarding was also associated with greater emotional attachment to possessions and to the reliance on possessions for emotional comfort. The implications of these findings for the definition of hoarding are discussed.  相似文献
