The present study investigated processes by which job stress and satisfaction unfold over time by examining the relations between daily stressful events, mood, and these variables. Using a Web-based daily survey of stressor events, perceived strain, mood, and job satisfaction completed by 14 university workers, 1,060 occasions of data were collected. Transfer function analysis, a multivariate version of time series analysis, was used to examine the data for relationships among the measured variables after factoring out the contaminating influences of serial dependency. Results revealed a contrast effect in which a stressful event associated positively with higher strain on the same day and associated negatively with strain on the following day. Perceived strain increased over the course of a semester for a majority of participants, suggesting that effects of stress build over time. Finally, the data were consistent with the notion that job satisfaction is a distal outcome that is mediated by perceived strain.  相似文献

Limited information exists on the racial attitudes and ethnic identities of groups of mixed racial origin. The present research tested the hypotheses that the construct of ethnic identity is valid among such groups and that ethnic identity is related to out-group prejudice, as predicted by social identity theory. The Multigroup Ethnic Identity Measure, the Anti-White Scale, and the Subtle Racism Scale were administered to 70 South Africans of mixed racial descent, the so-called Coloureds. A factor analysis supported the structural validity of the 12-item measure of ethnic identity with this sample, but correlations between scales did not support the prediction that group identity would be positively associated with out-group prejudice. Group identity was positively related .27 to positive attitudes toward Whites consistent with the tenets of social dominance theory.  相似文献

Studies of organic anterograde amnesia have been central to the development of theories of implicit memory. Pharmacological amnesia provides an additional method for exploring implicit memory, allowing for the experimental manipulation of amnesia and the testing of more participants. A significant concern with pharmacological amnesia is whether its cognitive effects are specific to explicit memory. The current research examines the effects of the benzodiazepine, midazolam, on retrieval from semantic memory and encoding in explicit memory. We focus on midazolam because it holds significant advantages over other benzodiazepines in inducing pharmacological amnesia and prior research suggests it may be useful for testing theories of implicit memory. Our results demonstrate that midazolam does not impair accuracy of retrieval from semantic categories, even when it produces anterograde amnesia for retrieved category items on a later recall test. These results suggest ways midazolam can be used to help test theories of implicit memory.  相似文献

The contribution of adolescent and parent perspectives to ethical planning of survey research on youth drug use and suicide behaviors are highlighted through an empirical examination of 322 7th-12th graders' and 160 parents' opinions on questions related to 4 ethical dimensions of survey research practice: (a) evaluating research risks and benefits, (b) establishing guardian permission requirements, (c) developing confidentiality and disclosure policies, and (d) using cash incentives for recruitment. Generational and ethnic variation in response to questionnaire items developed from discussions within adolescent and parent focus groups are described. The article concludes with a discussion of the potential contributions and challenges of adolescent and parent perspectives for planning scientifically valid and ethically responsible youth risk survey research.  相似文献

The purpose of this paper is to review research on the prevalence of children's exposure to domestic violence, to consider the available literature on the co-occurrence of domestic violence and child maltreatment, and to gain more understanding about the impact of exposure on children. There is clear evidence indicating that both severe and moderate violence occurs frequently in homes among family members and that children are exposed to this violence. However, because of differing definitions of what constitutes domestic violence and variability in research methodologies for collecting the data, there are significant discrepancies in prevalence reports across studies. Of great concern is the immediate impact on the children and the long-term consequences for their later relationships. Fewer studies have been done on the co-occurrence of domestic violence and child maltreatment. However, it is likely that children who live in homes where domestic violence occurs are more likely to be abused and neglected. On the basis of available research, there is little doubt that vast numbers of children are exposed to domestic violence and that children's responses vary widely depending on their risk and vulnerability, as well as the structure of their environments. A developmental risk and protective factors framework will be used to integrate the information on children's exposure to violence.  相似文献

The negative effects of false information presented either prior to (proactive interference; PI) or following (retroactive interference; RI) true information was examined with word definitions (Experiment 1) and trivia facts (Experiment 2). Participants were explicitly aware of which information was true and false when shown, and true-false discrimination was evaluated via multiple-choice tests. Negative suggestion, defined as poorer performance on interference items than noninterference (control) items, consistently occurred when the wrong information followed the correct information (RI) but not when it preceded the correct information (PI). These effects did not change as a function of retention interval (immediate, 1 week, or 3 weeks) or number of incorrect alternatives (1 or 3). Implications of this outcome for experiencing incorrect information in both academic and nonacademic situations are considered.  相似文献

Children quickly acquire basic grammatical facts about their native language. Does this early syntactic knowledge involve knowledge of words or rules? According to lexical accounts of acquisition, abstract syntactic and semantic categories are not primitive to the language-acquisition system; thus, early language comprehension and production are based on verb-specific knowledge. The present experiments challenge this account: We probed the abstractness of young children's knowledge of syntax by testing whether 25- and 21-month-olds extend their knowledge of English word order to new verbs. In four experiments, children used word order appropriately to interpret transitive sentences containing novel verbs. These findings demonstrate that although toddlers have much to learn about their native languages, they represent language experience in terms of an abstract mental vocabulary. These abstract representations allow children to rapidly detect general patterns in their native language, and thus to learn rules as well as words from the start.  相似文献

This study conducts a confirmatory factor analysis of the Beck Depression Inventory-II (BDI-II) with a sample of 598 individuals who reported recent injecting drug use. Findings indicate that out of four models tested, the best model for this sample is a three-factor solution (somatic, affective, and cognitive) previously reported by Buckley, Parker, and Heggie. The findings that nearly 50% of participants provided BDI-II scores indicating significant depressive symptomatology reveals that these individuals are in need of treatment for their psychiatric symptoms as well as substance use. Somatic symptoms are endorsed more strongly than affective or cognitive symptoms of depression, suggesting a possible, but yet poorly defined, relationship between depressive symptomatology and drug use that centers on shared somatic symptomatology.  相似文献

Controlled outcome studies investigating the efficacy of psychological treatments for obsessive-compulsive disorder (OCD) have employed different methods of determining the clinical significance of treatment effects. This makes it difficult to draw conclusions regarding the absolute and relative efficacy of psychological treatments for OCD. To address this issue, standardized Jacobson methodology for defining clinically significant change was applied to recent psychological outcome trials for OCD. The proportion of asymptomatic patients following treatment was also calculated. When recovery is defined by Jacobson methodology, exposure and response prevention (ERP) appears the most effective treatment currently available (50-60% recovered). However, when the asymptomatic criterion is used as the index of outcome, ERP and cognitive therapy have low and equivalent recovery rates (approximately 25%).  相似文献
