To assess the construct validity of the endogenous subtype of depression, 2 studies examined the relation of mood regulation skill to the symptoms of endogenous depression versus hopelessness depression in adolescent samples. It was hypothesized that the relationship between mood regulation skill and endogenous depression would be weaker than the relationship between mood regulation skill and hopelessness depression, because endogenous depression may be less influenced by personality variables, such as mood regulation skill. In spite of the high degree of correlation between the symptoms of hopelessness depression and endogenous depression, the relationship between mood regulation skill and hopelessness depression was stronger than the relationship between mood regulation skill and endogenous depression, as predicted. This is consistent with proposed definition of endogenous depression.  相似文献

Aging and depression have been found to be associated with poorer performance in mnemonic discrimination. In the current study, a two-response format mnemonic similarity test, Cognitive Drug Research MST, was used to compare these effects. Seventy-six participants were tested; with 52 participants in the young group, aged 18–35 years, and 24 participants in the elderly group, aged 55 years or older. Twenty-two young participants and 10 elderly participants met DSM-IV criteria for MDD or dysthymia. Age-related deficits were found for lure identification and speed of response. Differences in speed of responses to lure images were found for younger depressed participants, and depressive symptom severity was found to be negatively associated with lure identification accuracy in the elderly. These findings may be viewed as putative behavioral correlates of decreased pattern separation ability, which may be indicative of altered hippocampal neurogenesis in aging and depression.  相似文献

College students with elevated depressive symptoms are more likely to engage in risky drinking and experience alcohol-related negative consequences. Efforts to understand the association between depressed mood and alcohol use have begun to identify the role of cognitive-motivational processes. Drinking refusal self-efficacy is one such process that influences the decision to drink, but its relationship with depressed mood remains unclear. The current study sought to clarify the role of these processes using a depressed mood induction procedure in a sample of college student drinkers. Eighty-six students were randomized to a depressed or neutral mood induction and completed assessments of drinking refusal self-efficacy. Depressed mood significantly decreased self-efficacy in high-risk drinking contexts related to depression, whereas ratings of other high-risk contexts were unaffected. These findings suggest that the association between hazardous drinking and depressed mood may be due in part to the direct influence of mood state on one's self-efficacy to resist drinking in relevant contexts.  相似文献

The study is an examination of specific aspects of psychosocial constructs and health-promoting behavior that may be related to symptoms of depression. The authors used a case-control design to investigate possible differences between provisional social support, hardiness dimensions, and exercise behavior and related perceptions in a sample of 94 White, middle-aged women with and without symptoms of depression. The results indicated that women with symptoms of depression have significantly fewer (p < .001) specific forms of social support resources (i.e., reassurance of worth, social integration, guidance, and attachment) and significantly lower (p < .0001) perceptions of control and commitment in their lives. The results also indicated no difference in perceptions and behaviors related to physical activity between women with and without symptoms of depression. Those results suggest that provisional social support, as well as specific dimensions of hardiness, should be the focus of interventions for women with symptoms of depression.  相似文献

Drawing from minority stress theory and the systemic–transactional model, we examined whether perceptions of partner's dyadic coping behavior moderated the association between sexual orientation discrimination stress and symptoms of depression among individuals in a same-sex relationship. Data from 95 same-sex couples revealed that, overall, sexual orientation discrimination stress was positively associated with depressive symptoms; however, perceived partner emotion-focused supportive dyadic coping weakened this association. Specifically, higher sexual orientation discrimination stress was associated with greater depressive symptoms only for individuals perceiving low partner emotion-focused supportive dyadic coping. Implications for researchers and clinicians are presented.  相似文献

情绪状态对不同年龄儿童定势转换的影响   总被引:1,自引:0,他引:1       下载免费PDF全文
采用情绪影片引发情绪的方法,考察64名8~12岁儿童在正负情绪状态下定势转换能力的表现。研究为4(年龄)×2(情绪)×3(重复转换条件:重复、短时转换、长时转换)3因素重复测量混合设计。结果表明,情绪状态对任务转换产生了影响,可能是积极情绪比消极情绪对任务定势的长时转换削弱更大。不同年龄的儿童在这两种任务转换条件中没有出现显著的年龄差异,说明8~12岁儿童均已具备在两个任务之间进行即时转换的能力。  相似文献

Mood and basal hormone levels were measured before and after a 4-month training period in 20 professional basketball players on 2 different teams. Training volume was daily quantified by intensities, showing that Team 1 trained nearly twofold the volume of Team 2. Apart from the lack of differences between teams in anthropometric and physical variables, results showed mood improvements in the total sample without differences between teams. However, cortisol levels decreased in Team 1 and increased in Team 2, while the free testosterone–cortisol ratio, free testosterone, prolactin, and luteinizing hormone did not show significant changes. Changes in cortisol were positively related to depression and negatively related to training volume. Results suggest that differences exist in sensitivity and/or timing of both psychological and hormonal responses to 2 given volumes of training.  相似文献

Although much research has demonstrated a relationship between negative life events and depressive symptoms, relatively little research has examined the mechanisms that may mediate this relationship. The theories of Blatt (1974), Bowlby (1980), and Gilbert (1992) each propose proximal predictors of depression. In accordance with these theories, this study examined the relationships among perceived losses in self-worth and interpersonal relationships, anaclitic (dependent) and introjective (self-critical) mood states, and depressive symptoms following a significant negative life event. A sample of 172 undergraduate students completed measures of depressive symptoms and depressive vulnerability factors and retrospectively described the worst period of their lives. They also rated the extent to which the events surrounding this worst period affected their self-worth and their relationships with close others. Structural equation modeling demonstrated that the effect of a perceived loss of self-worth on depressive symptoms was fully mediated by both introjective and anaclitic mood states, whereas the effect of a perceived loss of interpersonal relationships on depressive symptoms was fully mediated by an anaclitic mood state. Additionally, perceived losses of self-worth showed a stronger effect on introjective mood in highly self-critical individuals. Findings highlight the importance of perceived losses in both self-worth and interpersonal domains in response to adverse life events and suggest pathways through which perceived losses may affect depressive symptoms.  相似文献

Face recognition occurs when a face is recognised despite changes between learning and test exposures. Yet there has been relatively little research on how variations in emotional expressions influence people’s ability to recognise these changes. We evaluated the ability to discriminate old and similar expressions of emotions (i.e. mnemonic discrimination) of the same face, as well as the discrimination ability between old and dissimilar (new) expressions of the same face, reflecting traditional discrimination. An emotional mnemonic discrimination task with morphed faces that were similar but not identical to the original face was used. Results showed greater mnemonic discrimination for learned neutral expressions that at test became slightly more fearful rather than happy. For traditional discrimination, there was greater accuracy for learned happy faces becoming fearful, rather than those changing from fearful-to-happy. These findings indicate that emotional expressions may have asymmetrical influences on mnemonic and traditional discrimination of the same face.  相似文献

采用整群抽样法选取438名学前儿童及其家长为被试, 通过量表考察父母述情困难、心境与儿童问题行为之间的关系。结果发现:(1)父亲述情困难与儿童焦虑害羞行为显著正相关, 父亲情绪愉悦在其述情困难与儿童焦虑害羞行为之间具有完全中介作用;(2)母亲述情困难与儿童愤怒攻击、焦虑害羞行为显著正相关, 同时母亲的情绪波动在其述情困难与儿童愤怒攻击行为之间起着部分中介作用。研究结果说明述情困难风险较高的父亲, 其情绪愉悦水平也相对较低, 进而导致儿童表现出更多焦虑害羞行为;述情困难风险较高的母亲, 一方面会直接导致儿童表现出较多愤怒攻击与焦虑害羞行为, 另一方面又会通过其情绪波动增加儿童出现愤怒攻击行为的风险。  相似文献

The present study attempts to examine how people perceive non-conforming behaviour and what do they infer about subjects who demonstrate non-conformity. Interviews were conducted to determine the operational definition and perception about non-conformity. Analysis of the interviews revealed that non-conformity is attributed to not abiding by the rules that have been defined or laid out by an authority in a particular context. Scenario-based experiments were conducted, and the obtained data were analysed to reach a conclusion regarding observers’ perception about non-conforming individuals in a collectivist culture. The results showed that non-conforming behaviour leads to a negative inference about status and competence. Also, we found that the attractiveness of non-conforming individuals does not lessen the negative inferences derived by the observers in a collectivist culture. The findings can be extended to devise several communication and signalling strategies to influence the mass behaviour in a collectivist culture, like India. The study provides us insights about achieving social objectives as well as driving behavioural change in a collectivist context.  相似文献

The main goal of this study was to investigate if adults sexually abused as children who were raised in a functional family are more able to generate specific autobiographical memories and suffer fewer depressive symptoms than sexually abused adults who were raised in a dysfunctional family. We found that abused males retrieved fewer specific memories than nonabused males, abused females, and nonabused females. The three latter groups did not differ from each other. Further, childhood sexual abuse did not predict depression among males and females. After accounting for family functioning, there were no group differences regarding memory specificity. Functional families appear to have beneficial effects on the adjustment of male victims of childhood sexual abuse.  相似文献

ABSTRACT. The effect of aerobic exercise on primary motor cortical excitability is a relevant area of interest for both motor learning and motor rehabilitation. Transient excitability changes that may follow an exercise session are a necessary precursor to more lasting neuroplastic changes. While the number of studies is limited, research suggests that a session of aerobic exercise can create an ideal environment for the early induction of plasticity. Potential mechanisms include the upregulation of neurotransmitter activity, altered cerebral metabolism and cortisol levels, and increases in brain-derived neurotrophic factor. While there is considerable evidence that chronic physical activity positively impacts brain health and function, studies examining cortical excitability changes and motor performance after a single session of exercise are lacking. Further research is required to determine the clinical utility and feasibility of aerobic exercise.  相似文献
