Few studies have compared the phenomenological properties of younger and older adults' memories for emotional events. Some studies suggest that younger adults remember negative information more vividly than positive information whereas other studies suggest that positive emotion yields phenomenologically richer memories than negative emotion for both younger and older adults. One problem with previous studies is a tendency to treat emotion as a dichotomous variable. In contrast, emotional richness demands inclusion of assessments beyond just a positive and negative dimension (e.g., assessing specific emotions like anger, fear and happiness). The present study investigated different properties of autobiographical remembering as a function of discrete emotions and age. Thirty-two younger and thirty-one older adults participated by recalling recent and remote memories associated with six emotional categories and completed the Memory Characteristics Questionnaire for each. Results demonstrated that older adults' angry memories received lower ratings on some phenomenological properties than other emotional memories whereas younger adults' angry memories did not show this same pattern. These results are discussed within the context of socioemotional selectivity theory.  相似文献

Is it possible to enhance the subjective wellbeing of individuals and societies? If so, what are the mental health interventions and economic mechanisms by which subjective wellbeing could be enhanced? We address these questions in our review of the literature on subjective wellbeing. Research now shows that although subjective wellbeing is heritable and stable, it can change substantially over time. Long‐term changes can be affected by positive or negative life events; subjective wellbeing interventions have also proved to be effective for boosting wellbeing for as long as six months. At the societal level, economic factors matter for the subjective wellbeing of citizens. Economic wealth is shown to be a predictor of societal wellbeing across countries and over time. Also, high unemployment severely lowers the wellbeing of individuals and has spillover effects on other societal members, such as the employed. Given the weight of evidence, we are optimistic that subjective wellbeing can be enhanced. For practitioners, policy makers, and economists interested in the wellbeing of individuals, we propose that these findings have implications for mental health practice and economic policies. Future research and methodological issues are discussed.  相似文献

ABSTRACT

With increasing market competitiveness, companies strive to deliver high-quality services. Negative reactions from employees to customer mistreatment erodes the quality of the service provided. This study investigated whether negative emotions and cognitive impairment are mechanisms through which customer mistreatment is related to generalized customer-directed incivility. 157 Italian (Study 1) and 259 Irish (Study 2) research participants completed questionnaires which included an experimental task that manipulated customer misbehaviour levels through scenarios to create three conditions (control, incivility, verbal aggression). Emotional reactions, cognitive impairment and generalized customer-directed incivility intentions as a result of the scenarios were investigated. In both studies, participants in the mistreatment conditions reported more negative emotions, greater cognitive impairment and higher generalized customer-directed incivility intentions than those in the control condition. In Italy (Study 1) negative emotions mediated the relationship between exposure to a customer mistreatment event and generalized customer-directed incivility intentions, but not in Ireland (Study 2), demonstrating the importance of considering contextual conditions in understanding such mediating mechanisms. This study extends research by showing how a single encounter with a misbehaving customer can contribute to the development of incivility intentions towards customers as entities. The implications of these findings for theory and practice are discussed.  相似文献

Using positron emission tomography (PET), we explored the neural correlates of an executive function, dual tasking, in patients with amnestic mild cognitive impairment (aMCI) and in elderly controls. The experiment employed simple auditory and visual tasks that were presented both in isolation and simultaneously to create a task condition requiring enhanced attentional control. Behaviorally, both groups performed well, albeit the patients made more errors on the visual task. The PET analysis focused at prefrontal regions where group differences in task-related activation patterns were expected. During dual task performance, the patients showed attenuated activity in the left inferior frontal region when compared to the controls. This suggests abnormalities in the neural processes underlying attentional control in aMCI.  相似文献

According to the levels-of-processing hypothesis, transitions from unconscious to conscious perception may depend on stimulus processing level, with more gradual changes for low-level stimuli and more dichotomous changes for high-level stimuli. In an event-related fMRI study we explored this hypothesis using a visual backward masking procedure. Task requirements manipulated level of processing. Participants reported the magnitude of the target digit in the high-level task, its color in the low-level task, and rated subjective visibility of stimuli using the Perceptual Awareness Scale. Intermediate stimulus visibility was reported more frequently in the low-level task, confirming prior behavioral results. Visible targets recruited insulo-fronto-parietal regions in both tasks. Task effects were observed in visual areas, with higher activity in the low-level task across all visibility levels. Thus, the influence of level of processing on conscious perception may be mediated by attentional modulation of activity in regions representing features of consciously experienced stimuli.  相似文献

Neural correlates of successful and unsuccessful verbal memory encoding   总被引:5,自引:0,他引:5  
Recent neuroimaging studies suggest that episodic memory encoding involves a network of neocortical structures which may act interdependently with medial temporal lobe (mTL) structures to promote the formation of durable memories, and that activation in certain structures is modulated according to task performance. Functional magnetic resonance imaging (fMRI) was used to determine the neural structures recruited during a verbal episodic encoding task and to examine the relationship between activation during encoding and subsequent recognition memory performance across subjects. Our results show performance-correlated activation during encoding both in neocortical and medial temporal structures. Neocortical activations associated with later successful and unsuccessful recognition memory were found to differ not only in magnitude, but also in hemispheric laterality. These performance-related hemispheric effects, which have not been previously reported, may correspond to between-subject differences in encoding strategy.  相似文献

Childhood abuse is an important precursor of borderline personality disorder (BPD) and antisocial personality disorder (ASPD). The current study compared the emotional reactivity to abuse-related stress of these patients on a direct and an indirect level. Changes in self-reported affect and schema modes, psychophysiology and reaction time based cognitive associations were assessed following confrontation with an abuse-related film fragment in patients with BPD (n = 45), ASPD (n = 21), Cluster C personality disorder (n = 46) and non-patient controls (n = 36). Results indicated a hyperresponsivity of BPD-patients on self-reported negative affect and schema modes, on some psychophysiological indices and on implicit cognitive associations. The ASPD-group was comparable to the BPD group on implicit cognitions but did not show self-reported and physiological hyper-reactivity. These findings suggest that BPD and ASPD-patients are alike in their implicit cognitive abuse-related stress reactivity, but can be differentiated in their self-reported and physiological response patterns.  相似文献

Theoretical models of depression posit that, under stress, elevated trait rumination predicts more pronounced or prolonged negative affective and neuroendocrine responses, and that trait rumination hampers removing irrelevant negative information from working memory. We examined several gaps regarding these models in the context of lab-induced stress. Non-depressed undergraduates completed a rumination questionnaire and either a negative-evaluative Trier Social Stress Test (n?=?55) or a non-evaluative control condition (n?=?69), followed by a modified Sternberg affective working memory task assessing the extent to which irrelevant negative information can be emptied from working memory. We measured shame, negative and positive affect, and salivary cortisol four times. Multilevel growth curve models showed rumination and stress interactively predicted cortisol reactivity; however, opposite predictions, greater rumination was associated with blunted cortisol reactivity to stress. Elevated trait rumination interacted with stress to predict augmented shame reactivity. Rumination and stress did not significantly interact to predict working memory performance, but under control conditions, rumination predicted greater difficulty updating working memory. Results support a vulnerability-stress model of trait rumination with heightened shame reactivity and cortisol dysregulation rather than hyper-reactivity in non-depressed emerging adults, but we cannot provide evidence that working memory processes are critical immediately following acute stress.  相似文献

Previous studies of autobiographical memory (AM) in schizophrenia yielded a reduction of specificity, richness of details and conscious recollection, which indicate both, quantitative and qualitative AM changes. However, their associations with psychopathological symptoms and neuropsychological deficits were not resolved. Therefore, we sought to investigate AM with respect to psychopathology and neuropsychology in patients with chronic schizophrenia to rule out the influence of different courses of the disease. AM of four lifetime periods was examined in 75 patients and 50 healthy controls by using a semi-structured interview. The recalled episodes were rated for memory specificity. Subsequently, one single event of each period of life was rated for details and experiential aspects of reliving (originality, vividness/visual imagery, emotional re-experiencing and emotional valence). When contrasted with healthy controls, patients recalled a significantly reduced number of episodes and personal semantic facts; moreover, memory specificity of AM was significantly lower in patients than controls. While the richness of details calculated for single events showed only minor, non-significant group differences, vividness and emotional re-experiencing were significantly less pronounced in the patient group. Along with this, AM performance correlated significantly with negative symptoms including apathy as well as verbal memory and executive functions. Our results underline the significance of overgenerality as a key feature of AM in schizophrenia as well as a dissociation between intact number of details of single events and reduced vividness and emotional re-experiencing. The extent of negative symptoms including apathy and impairments of verbal memory/executive functions may explain AM deficits in chronic schizophrenia.  相似文献

Hope is a motivational factor that helps initiate and sustain action toward long-term goals, including flexible management of obstacles that get in the way of goal attainment. Despite an abundance of research on the benefits of hope, little attention has been given to this aspect of youth development via longitudinal studies. In this study, we collected ratings of hope and positive and negative affect from 975 adolescents over a six-year assessment period (Grades 7–12). Using cross-lagged structural equation modeling, we found that hope led to greater positive affect, with little evidence for the reverse direction. In contrast, hope and negative affective states were reciprocally related. Hope predicted future well-being particularly well in years when the young people where in transition (e.g. starting high school and transitioning to senior high school). Our data support the position that hope is a malleable attribute that fosters positive youth development.  相似文献

This research examined a model of the stress response that includes cognitive-affective stress propensity, cognitive-affective processes, experienced affective reactions, subjective stress, and strain constructs. Using partial least squares analysis, this model was found to provide a good fit with the data. Moderated multiple regression analyses found support for the hypothesized moderating effects of individual stress propensity on the relationships of stressors with cognitive-affective processes. The research and practical implications of these findings are discussed.  相似文献

It is assumed that psychological stress may inhibit sexual arousal in women. Research on the effect of (acute and chronic) psychological stressors on genital and subjective sexual arousal, however, is scarce. To investigate whether psychological stressors indeed inhibit sexual responding, sexually functional women were randomly assigned to an experimental condition (n=30) in which acute psychological stress was induced by a frustrating computer task or a control condition (n=29). After the acute psychological stress or control induction women were exposed to an erotic stimulus. Genital sexual arousal was assessed using vaginal photoplethysmography. Self-report ratings of subjective sexual arousal were collected after the erotic stimulus. Furthermore, women were post hoc divided into a 'low' and a 'high' chronic stress group, based on their pre-assessment scores on a chronic daily stress questionnaire. As predicted, it was found that women in the acute stress condition responded with lower levels of genital and subjective sexual arousal to an erotic stimulus than women in the control condition. In addition, women with high levels of chronic stress responded with lower levels of genital sexual arousal to an erotic stimulus than women with low levels of chronic stress. Chronic stress did not affect the level of subjective sexual arousal.  相似文献

Managing occupational stress: A national and international perspective   总被引:1,自引:0,他引:1  
Theoretical models of occupational stress are important because they suggest a focus for intervention, and inform practice. The gap between research and practice was exposed most recently by Burke (1993) claiming little awareness of research findings by practitioners (managers, consultants, clinicians), little intervention activity being undertaken at the organizational level, little research being undertaken to determine the effectiveness of individual level interventions, and only modest use of work research findings for intervention and policy development (p. 85). This paper discusses the issue of intervention, and examines values, assumptions and the politics of applied research. A critical review of the evaluation studies of individual vs. organizational level interventions is undertaken and finally the problem of occupational stress as a national and international issue is considered.  相似文献

绝对音高(absolute pitch,AP)是一种比较罕见的音高加工能力,具有特殊的认知和神经机制。事件相关电位研究表明AP音乐家进行音高命名时,工作记忆参与较少但涉及多个认知策略。功能神经成像研究发现左侧额叶背侧后部和左侧颞叶平面对AP音乐家非常重要,而准AP音乐家(quasi-AP)的某些右侧脑区的参与则反映其增加的音高加工负荷和难度。结构神经成像研究发现AP音乐家具有特殊的灰质结构形态及白质连接。未来研究有待将AP能力进一步分为"具有相对音高能力"与"没有相对音高能力"两类并观察相应的认知神经机制,并通过影像基因组学来探索基因多态性对AP能力的影响,以及有必要观察以声调语言为母语的音乐家进行音高加工的神经机制。  相似文献

工作场所中,压力源无处不在;面对压力源,个体会如何反应?压力认知评价理论从认知评价和应对角度为这一问题提供了系统解释。在过去的40年里,该理论已成为阐释个体压力反应的主流框架。然而,由于提出时间较早,该理论没有提供各理论要素间的精确关系,这使得后续实证研究从各自研究问题出发,对该理论的应用五花八门,甚至因曲解理论观点而造成不当应用,不利于对该理论的持续应用和深入发展。在系统回顾理论观点的基础上,重点梳理了125篇以该理论作为核心理论基础的管理心理学实证研究。总体发现:在应用场景方面,压力认知评价理论可以用来解释6种压力源对员工工作态度、行为、身心健康和工作-家庭关系的影响;其应用形式可以从初级评价、次级评价和应对3个方面分别考虑;一些研究在应用该理论时存在误区。未来研究需要优化理论要素的测量方式,进一步拓展该理论的应用场景,同时丰富认知评价过程的影响因素研究。  相似文献

Long-term associations of prolonged stress symptoms and work-related stressors with chronic diseases were assessed in a sample of ageing and retired food industry workers (N = 100, mean age 62 years) using independent samples t-test, chi-squared test and binary logistic regression analyses. Data was gathered at health checkups and using self-report questionnaires in 1989 and 2000. Prolonged stress symptoms were associated with overall morbidity. Higher scores of stress symptoms predicted musculoskeletal disorders, diseases of the nervous system, eye and ear, endocrine and metabolic diseases, and mental disorders. Of work-related stressors, only job dissatisfaction had a long-term association with endocrine and metabolic diseases. Importantly, prolonged stress symptoms could not be explained by job strain and demands. Identification of prolonged stress symptoms along with traditional and potential risk factors, and combining this knowledge with stress reduction and management is essential for disease prevention and in postponing subsequent onset of disease.  相似文献

People's awareness of tactile stimuli has been investigated in far less detail than their awareness of stimuli in other sensory modalities. In an attempt to fill this gap, we provide an overview of studies that are pertinent to the topic of tactile consciousness. We discuss the results of research that has investigated phenomena such as "change blindness", phantom limb sensations, and numerosity judgments in tactile perception, together with the results obtained from the study of patients affected by deficits that can adversely affect tactile perception such as neglect, extinction, and numbsense. The similarities as well as some of the important differences that have emerged when visual and tactile conscious information processing have been compared using similar experimental procedures are highlighted. We suggest that conscious information processing in the tactile modality cannot be separated completely from the more general processing of spatial information in the brain. Finally, the importance of considering tactile consciousness within the larger framework of multisensory information processing is also discussed.  相似文献
