A between-subjects experiment examined selective exposure to films in an imagined self-control scenario, and if exposure would be systematically related to perceptions of the film content as challenging, enjoyable, and a should versus a want choice. Across 3 measures of selective exposure—using open-ended choice, closed-ended choice, and prospective ratings—participants in the depletion condition were less likely to select films that were cognitively challenging, affectively challenging, or a should choice. In contrast to nondepleted participants, depleted participants were more likely to select films they expected being fun, suspenseful, and less appreciated. These results provide support for the proposition that users’ momentary self-control capacity and their perception of challenge provided by content predict media choice.  相似文献

The study of executive function (EF) has become increasingly popular in multiple areas of research. A wealth of evidence has supported the value of EF in shaping notable outcomes across typical and atypical development; however, little evidence has supported the cognitive contributors to early EF development. The current study used data from a large longitudinal sample of healthy children to investigate the differential influence of verbal and nonverbal cognition on later EF. Participants were assessed at 2 years of age using the Mullen Scales of Early Learning, and Mullen scores were used to calculate nonverbal and verbal developmental quotients. Executive function was measured at 6 years using assessments from the Stanford-Binet, Cambridge Neuropsychological Test Automated Battery, and the Behavior Rating Inventory of Executive Function. Results suggested that early nonverbal cognition was a better predictor of 6-year EF as measured by task-based laboratory assessments, whereas verbal cognition was a better predictor of parent-reported EF. Findings are discussed in regard to EF development and characteristics of EF measurement.  相似文献

The present research tested a model of relationship functioning that incorporates meaning in life (MIL), proposing that MIL plays an important role in individuals’ motivations and perceived quality of romantic relationships. Study 1 employed a weekly diary methodology (N = 121 individuals in romantic relationships) and found that both within- and between-person relationship MIL are associated with internalized motivational states (i.e. intrinsic motivation, harmonious passion) and relationship quality (i.e. satisfaction, commitment). Study 2 was a dyadic study that examined both members of romantic couples (N = 238 dyads). Results found that both one’s own and one’s partner’s MIL predict motivation and relationship quality. Further, we also found evidence of a hierarchical model of MIL, such that relationship-specific experiences of MIL mediate associations between general MIL and relationship motivation and quality. Taken together, this research provides consistent and compelling evidence regarding the importance of MIL in romantic relationships.  相似文献

Premature termination from group psychotherapy continues to be a serious problem in the treatment of patients with borderline personality disorder (BPD). Qualitative research is regarded as an important means to shed light upon the complex dynamics leading to dropout. We conducted an interview study with patients having a diagnosis of BPD (n = 8) who dropped out from long-term group psychotherapy as a continuation therapy following intensive day treatment. The group therapists for these patients were interviewed as well (n = 12). The findings suggest the operation of many processes that contribute to dropout. Most significant appeared to be experiences of separation and loss of the day hospital that were not worked through and a failure of the group to regulate and contain the patients' affects. To integrate patients at risk of premature termination it seems necessary to pay attention to the strong negative emotions that they experience in the group. A higher treatment intensity than weekly group sessions may help to promote more beneficial group processes.  相似文献

Bone marrow transplantation (BMT) is an invasive and taxing treatment for certain cancers. This study investigated the psychological constructs of optimism and dispositional coping and their relative predictive role for situational coping. Participants were 85 cancer patients enrolled in a randomized clinical trial of T-cell depletion for prevention of graft-versus-host disease (GVHD) who completed baseline and 1-year interviews. Results of simultaneous regression analyses showed that optimism did not predict situational instrumental or palliative coping strategies but was negatively predictive of situational avoidant coping. Each of the three situational coping strategies was most strongly predicted by the corresponding dispositional coping strategy. This research was sponsored by the National Heart, Lung and Blood Institute: N01-HB-47095, N01-HB-47097, N01-HB-47094 and N01-HB-47098.  相似文献

ABSTRACT— When reminded of something we would prefer not to think about, we often try to exclude the unwanted memory from awareness. Recent research indicates that people control unwanted memories by stopping memory retrieval, using mechanisms similar to those used to stop reflexive motor responses. Controlling unwanted memories is implemented by the lateral prefrontal cortex, which acts to reduce activity in the hippocampus, thereby impairing retention of those memories. Individual differences in the efficacy of these systems may underlie variation in how well people control intrusive memories and adapt in the aftermath of trauma. This research supports the existence of an active forgetting process and establishes a neurocognitive model for inquiry into motivated forgetting.  相似文献

Sexual harassment has been recognized as a serious problem in the literature over the past 30 years. In this paper, we review the existing research surrounding the phenomenon of sexual harassment, paying particular attention to factors of relevance for understanding perpetrators of sexual harassment. We also provide an overview of the perplexing nature of sexual harassment and the various concerns that have surrounded the topic leading to its recognition. The different theoretical perspectives and models of sexual harassment (sociocultural, organizational, sex-role spillover, natural/biological, socio-cognitive, and four-factor) are also considered and reviewed. Finally, lack of empirical evidence and focus on assessment and treatment for harassers is recognized in this paper, and several suggestions are made for future research and treatment avenues relating to the sexual harasser.  相似文献

The habitual action perspective suggests that where transport users have strong travel choice habits, motivation will have no effect on behaviour. This has commonly been demonstrated in situations where travel habits and intentions conflict, but in stable decision settings intentions and habits will correspond. This paper reports two studies which demonstrate the moderating effect of habit on the intention–behaviour relationship within established commuting contexts. Results illustrate how motivational accounts of travel behaviour may be misleading if statistical significance of correlational data is the main criterion for model acceptance. Alternative methods for theory testing are discussed, and strategies for disrupting driving habits reviewed.  相似文献

Inattentive–hyperactive and oppositional behavior have been hypothesized to be developmental precursors to conduct problems. We tested these hypotheses using a longitudinal sample of 6,466 offspring of women selected from nationally representative US households. Conduct problems across 8–13 years were robustly predicted by conduct problems at 4–7 years, but also were independently predicted to a small extent by both inattentive–hyperactive and oppositional behaviors at 4–7 years. Longitudinal multivariate behavior genetic analyses revealed that the genetic and environmental factors that influence conduct problems at both 4–7 and 8–13 years also influence the putative precursors at 4–7 years. After genetic and environmental influences on conduct problems at 4–7 years were taken into account, however, inattentive–hyperactive and oppositional behavior at 4–7 years shared causal influences with conduct problems 8–13 years to a negligible extent. These findings suggest that after early conduct problems are controlled, little is gained in terms of prediction or understanding genetic and environmental influences on later child conduct problems by treating early inattentive–hyperactive and oppositional behavior as developmental precursors to later conduct problems.  相似文献
