Intrusive images and memories in major depression 总被引:1,自引:1,他引:0

Individuals with current major depression were interviewed to investigate the prevalence of distressing intrusive mental imagery among depressed patients and study the phenomenology of these intrusions. Of the 39 currently depressed patients, 17 experienced some form of repetitive intrusive imagery (i.e., either an intrusive memory or image), with intrusive memories being more common than images. The intrusive imagery was experienced as highly uncontrollable and interfered significantly with patients' everyday lives. The intrusions were experienced with a sense of 'nowness', as well as physical and emotional re-experiencing. Despite high levels of re-experiencing, levels of dissociation were very low. The intrusive imagery was in some patients part of a wider network of key defining autobiographical memories, consistent with the idea that it is likely to play a significant role in maintaining the patient's depressive mood. Interventions targeting these intrusions could potentially result in a positive shift in depressed mood. 相似文献

Differential reinforcement of alternative behavior (DRA) may result in rates of reinforcement that are impractical for caregivers to implement; therefore, recent research has examined methods for thinning reinforcer delivery during DRA. In this study, reinforcer delivery was thinned during DRA by restricting access to the participant's alternative response materials. 相似文献

The authors conducted 4 studies investigating the reliability and validity of the Eating Disorder Diagnostic Scale (HDDS; E. Stice, C. F. Telch, & S. L. Rizvi, 2000), a brief self-report measure for diagnosing anorexia nervosa, bulimia nervosa, and binge eating disorder. Study 1 found that the HDDS showed criterion validity with interview-based diagnoses, convergent validity with risk factors for eating pathology, and internal consistency. Studies 2 and 3 found that the EDDS was sufficiently sensitive to detect the effects of eating disorder prevention programs. Regarding predictive validity, Studies 3 and 4 found that the EDDS predicted response to a prevention program and future onset of eating pathology and depression. Results provide additional evidence of the reliability and validity of this scale and suggest it may be useful in clinical and research applications. 相似文献

This paper describes Skills for Academic and Social Success (SASS), a cognitive–behavioral, school-based intervention for adolescents with social anxiety disorder. Clinic-based treatment studies for socially anxious youth are reviewed, and a strong rationale for transporting empirically-based interventions into schools, such as SASS, is provided. The SASS program consists of 12, 40-min group sessions that emphasize social skills and in-vivo exposure. In addition to group sessions, students are seen individually at least twice and participate in 4 weekend social events with prosocial peers from their high schools. Meetings with teachers provide information about social anxiety and facilitate classroom exposures for socially anxious participants. Parents attend 2 psychoeducational meetings about social anxiety, its treatment, and approaches for managing their childs anxiety. Initial findings regarding the programs effectiveness are presented. We conclude by discussing the challenges involved in implementing treatment protocols in schools and provide suggestions to address these issues. 相似文献

In the present experiments, predictions of common path and recursive-reminding models of recognition (RG) and judgments of frequency (JOFs) were contrasted. The results indicated that each task is affected by study frequency, printed frequency, and associative connectivity. However, effect size analyses indicated that study frequency and item attributes show a double dissociation over tasks. Study frequency has a greater effect on JOFs than on RG, whereas printed frequency and associative connectivity have greater effects on RG than on JOFs. The recursive-reminding model predicts differential effects of study frequency, because it assumes that although both tasks are influenced by familiarity, JOF is more likely to be affected by recollective reminding as a procedure for encoding event frequency. Associative set size effects were absent in each task, suggesting that competitors play no role in either task. 相似文献

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

Midazolam amnesia and retrieval from semantic memory: Developing methods to test theories of implicit memory 总被引:1,自引:0,他引:1
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

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
