College student smokers (N = 50) were asked to carry electronic diaries for 14 days and record smoking events (n = 1,139). They indicated why they were smoking each cigarette on a checklist of potential motives. Results suggest that a desire to reduce craving (62.8% of occasions) and habit/automatic processes (42.8%) were the most frequent motives. More dependent and daily smokers were especially likely to endorse smoking to reduce craving and for habit/automatic reasons and were less likely to cite coping with negative emotion as a reason for smoking. Dependent and daily smokers were more likely to endorse at least 1 dependence-like motive and were less likely to exclusively attribute smoking to nondependence motives. Self-monitored motives appeared valid, according with conceptually related states, activities, and events in the diary records. Diary-recorded motives were compared with smokers' responses to a retrospective motives questionnaire administered at baseline. The 2 assessment modes produced discrepant estimates of the most influential motivational processes. Questionnaire responses incompletely forecast conceptually similar diary-reported motives. Dependence and daily smoking showed a different pattern of associations with diary-based versus retrospective motives measures.  相似文献

Rapid word learning under uncertainty via cross-situational statistics   总被引:2,自引:0,他引:2  
There are an infinite number of possible word-to-word pairings in naturalistic learning environments. Previous proposals to solve this mapping problem have focused on linguistic, social, representational, and attentional constraints at a single moment. This article discusses a cross-situational learning strategy based on computing distributional statistics across words, across referents, and, most important, across the co-occurrences of words and referents at multiple moments. We briefly exposed adults to a set of trials that each contained multiple spoken words and multiple pictures of individual objects; no information about word-picture correspondences was given within a trial. Nonetheless, over trials, subjects learned the word-picture mappings through cross-trial statistical relations. Different learning conditions varied the degree of within-trial reference uncertainty, the number of trials, and the length of trials. Overall, the remarkable performance of learners in various learning conditions suggests that they calculate cross-trial statistics with sufficient fidelity and by doing so rapidly learn word-referent pairs even in highly ambiguous learning contexts.  相似文献

The purpose of this study was to examine the occurrence of depression among adolescents attending family planning clinics, and to determine the relationship among depression, a history of sexual abuse, and other risk behaviors. The sample consisted of 279 minority females. Results of the study indicated that 40 adolescents (14.3%) scored at or above a raw score of 77 for depression based on the Reynolds Adolescent Depression Scale (RADS). This suggests that these adolescents should be identified for further evaluation. Results of the Stepwise Linear Regression indicated that a history of sexual abuse was the most potent factor in predicting depression. These findings highlight the importance of screening concurrently for depression and a history of sexual abuse in family planning and other healthcare settings.  相似文献

Cognitive models of social phobia predict that several cognitive processes will mediate the relationship between trait levels of social anxiety and the extent of anxiety experienced in a specific social-evaluative situation. The current study aimed to provide a test of these relationships. Over 200 clinical participants with social phobia completed measures of their general social anxiety and a week later performed a brief impromptu speech. They completed a measure of state anxiety in response to the speech as well as questionnaires assessing several cognitive constructs including focus of perceived attention, perceived performance, and probability and cost of negative evaluation. A week later, they completed measures of negative rumination experienced over the week, as well as a measure of the recollection of their perceived performance. Path analysis provided support for a model in which the cognitive factors mediated between general social anxiety and the degree of anxiety experienced in response to the speech. A second model supported the theory that negative rumination mediated between characteristic social anxiety and negative bias in the recollection of performance.  相似文献

Clarification and elaboration on evidence-based practice in psychology   总被引:1,自引:0,他引:1  
Responds to comments by D. C. Wendt and B. D. Slife, P. H. Hunsberger, and R. B. Stuart and S. O. Lilienfeld regarding the report by the APA Presidential Task Force on Evidence-Based Practice entitled Evidence-based practice in psychology. The goal of the task force was to create a scheme that would suggest how evidence should be used to design and offer services that will benefit patients and to assure the public and the health care system that psychologists are providing evidence-based services. There were and will continue to be many scientific and philosophical issues inherent in any such enterprise, and agreement by all psychologists with every aspect of EBPP may not be possible. Nevertheless, the APA's EBPP policy and the report that accompanied it are remarkably inclusive of various perspectives while remaining unambiguous about the need to use evidence in a way that leads to effective services. What is needed at this point are clinically relevant evidence and investigations of how such evidence can be used to best benefit those served by psychological interventions.  相似文献

The effect of attentional focus on social anxiety   总被引:1,自引:0,他引:1  
The aim of the present study was to examine the effect of attentional focus on social anxiety in a group of high and low blushing-anxious subjects. One hundred and fourteen psychology undergraduate students were screened using the Fear of Blushing subscale of the Blushing Questionnaire [B?gels, S. M., & Reith, W. (1999). Validity of two questionnaires to assess social fears: The Dutch social phobia and anxiety questionnaire and the blushing, trembling and sweating questionnaire. Journal of Psychopathology and Behavioral Assessment, 21, 51-66]. Those with the most extreme scores in the top and bottom 20% of the distribution were selected to form a high (n=22) and a low (n=22) blushing-anxious group. Subjects were randomly allocated to either a self-focused attention (SFA) condition or a task-focused attention (TFA) condition. They were asked to engage in a 5 min conversation with the first author, and were instructed to either self-focus (SFA condition) or task-focus (TFA condition). Levels of social anxiety and self-awareness were measured using visual analogue scales. Results suggest that the there was a significant condition by group interaction, with high blushing individuals showing considerably higher levels of social anxiety in the SFA condition compared to the TFA condition while low blushing individuals showed no significant difference across the two conditions.  相似文献

The demands of the modern office are thought to contribute to the development of musculoskeletal disorders. For upper body and lower back disorders, these effects are hypothesized to be mediated by psychological strain. A study of 936 employees from 22 call centers supports this hypothesis. Using logistic regression and structural equation modeling, the authors found that the relationship of workload to upper body and lower back musculoskeletal disorders was largely accounted for by job-related strain. This mediating effect was less evident for arm disorders. Contrary to expectation, job autonomy had neither a direct nor a moderating effect on any musculoskeletal disorder.  相似文献

Visual search can be resumed more rapidly following a brief interruption to an old display than it can be initiated on a new display, pointing to a critical role for memory in search (Lleras, Rensink, & Enns, 2005). Here, we examine how this rapid resumption is affected by changes made to the display during the interruption of search. Rapid resumption was found to depend on the prior presentation of the target, not merely the distractor items (Experiment 1), and was unaffected by the relocation of all distractor items (Experiment 2). Further, whereas changes to response-irrelevant features of the target did not eliminate rapid resumption (Experiment 3), changes to response-relevant features did (Experiment 4). These results point to the target specificity of rapid resumption and are consistent with reentrant theories of visual awareness.  相似文献

This article reviews studies examining the efficacy of behavioral interventions for the treatment of attention-deficit/hyperactivity disorder (ADHD). A specific emphasis is placed on evidence-based interventions that include parent training, classroom, academic, and peer interventions. Results indicate that school-aged children respond to behavioral interventions when they are appropriately implemented both at home and in the classroom setting. Combined treatments (behavioral management and stimulant medication) represent the gold standard in ADHD treatment and are often recommended as the first-line treatment option due to the many problems faced by children with ADHD. Diversity issues, although an important consideration in the treatment of ADHD, continue to remain an understudied area. Recommendations for future research are made pertaining to treatment sequencing with regard to behavior management as well as for subgroups of ADHD children who may respond best to specific treatments.  相似文献
