To date, few prospective studies of life events and bipolar disorder are available, and even fewer have separately examined the role of life events in depression and mania. The goal of this study was to prospectively examine the role of negative and goal-attainment life events as predictors of the course of bipolar disorder. One hundred twenty-five individuals with bipolar I disorder were interviewed monthly for an average of 27 months. Negative and goal-attainment life events were assessed with the Life Events and Difficulties Schedule. Changes in symptoms were evaluated using the Modified Hamilton Rating Scale for Depression and the Bech-Rafaelsen Mania Scale. The clearest results were obtained for goal-attainment life events, which predicted increases in manic symptoms over time. Negative life events predicted increases in depressive symptoms within regression models but were not predictive within multilevel modeling of changes in depressive symptoms. Given different patterns for goal attainment and negative life events, it appears important to consider specific forms of life events in models of bipolar disorder. 相似文献

ABSTRACTPerceptions of museum performance may be linked to individual values. This study asked members of different groups that hold a stake in a university museum (e.g., Alaska Native, Art Community, Business Community, Donors/Museum Members, Military Leaders, Science Community, K–12 Teachers, University Leaders) what they valued about their museum's performance. Results indicate that key differences exist with respect to performance indicators among some groups; however, stakeholders as a whole highly value indicators related to the human face of the museum and the collections. Museums can use these results to develop and pursue appropriate goals for specific audiences and to develop performance reports that matter to stakeholders. 相似文献

Two experiments provide convergent evidence for the hypothesis that listeners interpret chords in terms of their harmonic functions in a system of interrelated keys. The perceived associations between chords undergo significant changes depending on the broader tonal framework in which they are embedded. Three independent context effects are identified, and their magnitude is found to be a systematic function of the distance between the context key and the key lot keys) of which the chords are members. In the first experiment, listeners rate how musically related one chord is to a second chord; the chords are those that function within two maximally distant major keys (C major and F# major). All possible chord pairs from this set are presented in each of three context keys: G major which is close to C major and distant from F# major), A major (which is moderately distant from both C major and F# major), and B major (which is close to F# major and distant from C major). The second experiment measures recognition memory for the same chords embedded in tonal sequences in C, G, A, or B major keys, or random sequences. In the two experiments, the distance between the context key and the key of the chords on the circle-of-fifths affects: (1) the probability that a repeated chord is correctly recognized, (2) the strength of association between chords from the same key measured in terms of both confusion errors and direct relatedness judgments, and (3) asymmetries in confusion errors and relatedness judgments when the chords are in different keys. Perceived harmonic relations are thus found to be strongly context dependent, but the context effects are lawful functions of interkey distance. We conclude that listeners possess a highly articulated system of knowledge about the harmonic functions of chords in musical keys and an appreciation of musical structure at the level of abstract tonal centers. 相似文献

Sansone, Weir, Harpster, and Morgan (1992) found that individuals intentionally regulated their interest in an activity when they had both the need (the task was boring) and a reason to exert the effort (an ostensible health benefit). The present study examined Hardiness and Conscientiousness as moderators of this self-regulatory process when individuals had the option of quitting in addition to the options of persisting and of engaging in interest-enhancing strategies. Undergraduates performed a boring copying activity under instructions to stop when they felt they could evaluate the task. Half were told that their evaluations would help researchers develop good jobs for others (Benefit). Results indicated high hardy individuals copied more letters when they were provided the additional Benefit information, and this effect was mediated through their attempt to make the task more interesting. High conscientious individuals persisted longer than individuals lower in conscientiousness independently of the benefit manipulation or strategy use. Implications of individual differences in self-regulation of motivation are discussed. 相似文献

This study examined the impact of a 12-wk. sport stacking intervention on reaction time (RT), manual dexterity, and hand-eye coordination in elementary school-aged children. 80 Grade 2 students participated in a 15-min. sport stacking practice session every school day for 12 wk., and were tested on psychomotor performance improvement. Tests for choice RT, manual dexterity, and photoelectric rotary pursuit tracking were conducted pre- and post-intervention for both experimental group (n = 36) and the controls (n = 44) who did no sport stacking. Students who had the intervention showed a greater improvement in two-choice RT. No other group difference was found. Such sport stacking activities may facilitate children's central processing and perceptual-motor integration. 相似文献

Interviews with seven women and six men who had recently returned to work after becoming first-time parents were carried out to examine experiences of the policies, practices and attitudes of their employers towards new parents, and to assess how far they felt able to discuss their circumstances and changed expectations with their managers. Findings pointed to considerable differences in the attitudes of employers to the men and women. Almost all the women had changed to part-time work, but arranging this had not been easy and some had found it difficult to come to terms with a difference in status. Many of the respondents had reservations about discussing their positions and altered expectations with their managers, and it seemed unlikely that mutually beneficial psychological contracts could be negotiated without changes in organisational cultures and policies. The findings have implications for our understanding of organisational careers and for career-planning interventions in organisations. 相似文献

Children (N = 404) provided data during 3rd and 4th grades concerning their mothers’ use of punitive discipline and yielding to coercion. Teachers provided data regarding their perceptions of children’s externalizing behaviors at school. We tested a cross-lagged model examining parental disciplinary behaviors as predictors of child externalizing behavior, as well as child externalizing behaviors as a predictor of parental disciplinary behaviors. For boys and for girls, there was over-time stability in all three variables of interest. For boys only, more externalizing behaviors in Grade 3 predicted greater use of punitive discipline by parents and more parental yielding to coercion in Grade 4, over and above Grade 3 levels of these parenting variables. The reverse direction of effects was not observed. 相似文献
