This study evaluated the interactive effects of message framing and temporal context on college student alcohol use. Participants (n = 228) were randomly assigned to read an alcohol prevention message that varied by message frame (gains vs. losses) and temporal context (short- vs. long-term consequences). Participants returned to the lab one month later to report their drinking behavior over the past month. As predicted, students exposed to the gain-framed message reported lower alcohol use (drank less frequently, drank fewer alcoholic beverages per drinking occasion, and engaged in less binge drinking) as compared to students exposed to the loss-framed message, but only if they read about short-term consequences of alcohol use. Message frame had no effect when participants were exposed to long-term consequences. This investigation extends previous research by demonstrating the effectiveness of message framing for reducing health-damaging behaviors and by identifying temporal context as a moderator of framing effects.  相似文献

In this longitudinal study, we compared family stories told by 32 Canadian adolescents at ages 16 and 20 about how parents and grandparents had taught them values. Relations to parents' and children's levels of generativity were also examined. Adolescents' stories of grandparent value teaching were less readily recalled and less interactive in their content compared with stories about parents. Stories of value teaching by more generative parents were more likely to involve specific episodes, to be more interactive, to be more likely to emphasize caring content, and to be less likely to have their message rejected by the teens. Similarly, when parents were more generative, adolescents' stories about grandparents' value teaching were also more likely to involve specific and interactive episodes. Finally, stories told about parents and grandparents that were more positive on these dimensions predicted higher generative concern scores for the adolescents themselves, measured subsequently at age 24. Adolescents' stories about parent and grandparent socialization in more generative family contexts thus have features that suggest a more compelling process of intergenerational value transmission.  相似文献

In Conway and Pleydell-Pearce's model (2000), autobiographical memories are viewed as transitory mental representations, more often generated in an effortful way. An important claim of the model concerns the dynamic process that evolves over time, from the left prefrontal areas to posterior regions, to retrieve specific memories. The present work aims at investigating, using fMRI, the temporal distribution of effortful autobiographical memory construction. In addition, a self-paced design was implemented to elucidate the question of the timing window required to evoke recollections. The results showed a large pattern of brain regions, which included the two major poles of activation predicted by Conway and Pleydell-Pearce's model. Likewise, we were able to detect the earlier implication of the left dorso-lateral prefrontal cortex, by comparison with posterior structures, which seemed to confirm its involvement in the effortful retrieval process. Finally, the self-paced procedure allowed us to refine the timing window necessary to construct past events.  相似文献

Analysis of acoustic interactions between animals in active choruses is complex because of the large numbers of individuals present, their high calling rates, and the considerable numbers of vocalizations that either overlap or show close temporal alternation. The authors describe a methodology for recording chorus activity in bullfrogs (Rana catesbeiana) using multiple, closely spaced acoustic sensors that provide simultaneous estimates of sound direction and sound characteristics. This method provides estimates of location of individual callers, even under conditions of call overlap. This is a useful technique for understanding the complexity of the acoustic scene faced by animals vocalizing in groups.  相似文献

This article presents a new approach to the assessment of structural personality pathology: theory-driven profile interpretation of the Dutch Short Form of the MMPI (DSFM). The assessment method integrates results of a self-report personality questionnaire with psychodynamic theoretical concepts to yield a working hypothesis about underlying structural features of personality. As an illustration, results of a validation study with psychotic phenomena in projective drawings as the external criterion are described. Results show that the DSFM profiles, that are presumed to measure psychotic vulnerability predict psychotic phenomena in projective drawings, after statistically controlling for the effect of age, the single scales that are being used to construct the profiles and their statistical interaction.Results suggest that theory-driven profile interpretation of the DSFM may be considered a time and cost efficient method to derive a working hypothesis about structural vulnerability.  相似文献

The National Board for Certified Counselors describes cybercounseling as the provision of some aspects of counseling through technology, via such applications as e‐mail, Web‐based information access, course registration, academic advising, and career guidance. The authors explore the characteristics of cybercounseling, describe its current use in the United States and South Korea, explore its advantages and disadvantages, and consider issues and concerns for college counselors.  相似文献

In this paper, we directly assess perceived similarity—the degree to which members view themselves as having few differences—because we want to understand when teams notice diversity on various member characteristics and how they interpret it. Our results indicate social category diversity was related to initial estimates of both perceived social category similarity (SCS) and perceived work style similarity (WSS). And, whereas perceived SCS did not change over time, perceived WSS decreased significantly over the period of our study. We suggest this change in perceived WSS can be explained by an information-processing/decision-making framework. We found informational diversity was positively related to conflict in teams, and in turn conflict was negatively related to subsequent estimates of perceived WSS. However, informational diversity was positively related to information sharing in teams, which in turn was positively related to subsequent estimates of perceived WSS. Finally, these updated estimates of perceived WSS affected subgroup formation and team process effectiveness. We discuss how our research explores the subjective experience of diversity by team members, provides a dynamic view of the relationship between diversity and team outcomes, and informs emerging theory about the activation of faultlines in teams.  相似文献

We discuss three theoretical models from met expectations research in the fields of organizational behavior and consumer psychology. Based on the fundamental arguments in the models, we term these models: disconfirmation, ideal point, and experiences only. We present three-dimensional graphical and analytical representations of the models, with satisfaction being a function of expectations and experiences. We tested the models in the context of a new information system implementation in an organization, with expectations, experiences, and system satisfaction measured for both ease of use and usefulness, the focal constructs of the Technology Acceptance Model (TAM). We found that an experiences only model in which expectations had no measurable effect best explained the data for ease of use. The results for usefulness indicated a modified version of the experiences only model in which the positive effect of experiences becomes slightly stronger—i.e., more positive—as expectations increase.  相似文献

The main objective of this study was to determine whether being taught the latest information concerning borderline personality disorder (BPD) leads to a decline in core BPD symptoms and an improvement in psychosocial functioning. Fifty-five late adolescent women participated in a rigorous diagnostic assessment and 50 met DIB-R and DSM-IV criteria for BPD. All 50 were informed that they met criteria for BPD. Then 30 were randomized to a psychoeducation workshop that took place within a week of diagnostic disclosure. The other 20 were assigned to a waitlist and participated in the workshop at the end of this 12-week study. The two primary outcome measures were readministered each week of the trial: the Zanarini Rating Scale for DSM-IV Borderline Personality Disorder (ZAN-BPD) and the Sheehan Disability Scale (SDS). Immediate psychoeducation concerning the BPD diagnosis was associated with a significantly greater decline in general impulsivity and the storminess of close relationships. However, it did not result in significantly improved psychosocial functioning. Taken together, the results of this study suggest that informing patients about BPD soon after diagnostic disclosure may help to alleviate the severity of two of the core elements of borderline psychopathology-general impulsivity and unstable relationships. They also suggest that such instruction may prove to be a useful and cost-efficient form of pre-treatment.  相似文献

Among individuals with Rheumatoid Arthritis (RA), pain-associated stress can severely impact wellbeing. Psychological attributes, such as a sense of personal mastery, may attenuate the effects of chronic pain on life quality. We tested the hypothesis that a high sense of mastery would predict lower pain, perceived stress, fatigue, and mean arterial pressure (MAP) than would a low sense of mastery during an acute, interpersonal stressor.Seventy-four individuals with RA completed a psychophysiological laboratory session involving MAP measurements, as well as self-ratings of stress, joint pain, and fatigue. Measurements were collected before, during, and after an interpersonal stressor. To assess personal mastery, exploratory and confirmatory factor analyses were conducted on the Pearlin Mastery Scale based on recommendations by Reich and Zautra (1991)The Pearlin Mastery Scale yielded two distinct factors: fatalism and control. Both fatalism and control were significant predictors of the wellbeing variables. Individuals with a highly fatalistic style demonstrated higher general levels of mean arterial pressure (F(1) = 3.41, p<.1) and reported greater joint pain (F(1) = 4.72, p<.05) across all periods. Individuals with a high sense of control also evidenced lower MAP (F(1) = 3.73, p<.1) and reported less stress (F(1) = 7.44, p<.01) and fatigue (F(1) = 5.16, p<.05). Neither fatalism nor control were related to objective measures of disease severity (r's = -.10, p=NS and -.02, p=NS, respectively).RA patients with a high level of personal mastery, as evidenced by scores on two distinct indices, experience lower MAP, and report less pain, stress and fatigue. Although fatalism and control were not related to objective disease state, they seem to play an important role in the experience of wellbeing for people with RA.  相似文献
