使用情绪图片作为背景任务刺激,通过两个实验来考察积极情绪和消极情绪对时间性和事件性前瞻记忆的影响。结果发现,对于背景任务的反应时,在时间性前瞻记忆和事件性前瞻记忆中,情绪的主效应都显著。而对于前瞻任务的正确率,在两种前瞻记忆中,情绪的主效应都不显著。将两个实验的数据合并分析发现,对于前瞻任务的正确率,任务类型的主效应显著,即时间性前瞻记忆的成绩显著高于事件性前瞻记忆; 而情绪的主效应不显著。结果表明,背景任务中不同的情绪刺激会对个体完成背景任务的速度产生影响,而对前瞻记忆任务的执行不会产生影响。  相似文献

Background and objectives: Previous studies on traumatic memory have primarily focused on the correlation between traumatic symptoms and negative memories, often utilizing the directed forgetting paradigm. Different from previous research, this study aimed to examine the correlation of post-traumatic growth (PTG) and positive memories, with the objective to explore the directed forgetting effect of positive material and its relationship with PTG.

Design: A 2 (PTG level: high vs. low)?×?2 (instructions: To-Be-Forgotten vs. To-Be-Remembered)?×?3 (word valence: positive vs. neutral vs. trauma related) mixed-factorial-designed experiment was applied.

Methods: Participants were 46 senior high-school students who had survived in the Sichuan earthquake in 2008. Participants were divided into two groups based on PTG: high (n?=?24) and low (n?=?22). Both groups were presented, and asked to recall, three word categories (positive, trauma-related, and neutral) following the directed forgetting paradigm.

Results: A mixed-design factorial ANOVA yielded a significant interaction effect of word valence and PTG group, with the high-PTG group recalling more positive words than the low-PTG group.

Conclusions: This was the first study to identify a key cognitive process of PTG by integrating the directed forgetting paradigm into an investigation of PTG.  相似文献

Fibromyalgia (FM) is a chronic pain syndrome that includes debilitating symptoms such as widespread pain and tenderness, fatigue, and poor physical functioning. Research has shown FM patients’ choice of coping style and relationship quality with their spouse can impact their mental quality of life (QoL), but no known study has examined the protective nature of relationship quality and coping behaviors on both patient physical and mental QoL in the context of chronic pain. We examined 204 patients with FM on the (a) roles of coping styles and relationship quality on patient quality of life, and (b) moderating effect of relationship quality on the association between negative coping style and patient QoL. A series of multiple regressions found patients’ coping styles were not significantly associated with physical QoL, but were significantly associated with mental QoL. Patients’ relationship quality with their spouse was significantly associated with mental QoL, but not physical QoL and no significant interactions with negative coping style were found. Our results emphasize the importance of coping styles and relationship quality between patients and their spouses in the context of chronic pain. Clinicians can incorporate the patient’s relationship as part of a more holistic approach to care and improving outcomes.  相似文献

The objective of this study was to evaluate the feasibility and preliminary efficacy of a self-efficacy enhancing intervention designed for pulmonary rehabilitation based on motivational interviewing (MI) for postsurgical non-small cell lung cancer (NSCLC) patients. This study was a 2-arm pilot randomized controlled trial and was conducted in two cardiothoracic surgery departments, a tertiary hospital in Fuzhou, China. 28 postsurgical NSCLC patients were randomized to a 3 month (6 session) self-efficacy enhancing intervention based on MI or usual care (UC). Data were measured at baseline and after intervention. The MI based self-efficacy enhancing intervention group was superior to the UC group for reducing anxiety and depression, improving self-efficacy, quality of life, confrontational coping, social support and functional capacity. However, no statistically significant difference was observed in subjective well-being, posttraumatic growth, body mass index and pulmonary function between the two groups. This pilot study demonstrated the feasibility of MI based self-efficacy enhancing intervention for postsurgical NSCLC patients. A larger randomized trial would demonstrate a more rigorous test of efficacy.  相似文献

Our aim was to explore the independent attribution of Post-stroke depression (PSD) to caregiver burden of acute ischemic stroke patients. A cross-sectional survey was performed with 271 acute ischemic stroke patients in the Huai-He Hospital and First People’s Hospital of Kaifeng City in China. PSD was assessed by Self-rating Depressive Scale, and caregiver burden was assessed by Zarit Caregiver Burden Interview. Clustered logistic regression was applied to identify the impact of PSD on caregiver burden. As results, female patients, normal muscle strength and PSD were associated with caregiver burden. PSD correlated with an independent influence of 17.2% on the risk of caregiver burden, The independent influence of PSD on caregiver burden was smaller than that of social-demographics of caregivers and clinical factors of stroke patients This study suggests that PSD may have a modest influence on caregiver burden.  相似文献

Children's understanding of the quantities represented by number words (i.e., cardinality) is a surprisingly protracted but foundational step in their learning of formal mathematics. The development of cardinal knowledge is related to one or two core, inherent systems – the approximate number system (ANS) and the object tracking system (OTS) – but whether these systems act alone, in concert, or antagonistically is debated. Longitudinal assessments of 198 preschool children on OTS, ANS, and cardinality tasks enabled testing of two single‐mechanism (ANS‐only and OTS‐only) and two dual‐mechanism models, controlling for intelligence, executive functions, preliteracy skills, and demographic factors. Measures of both OTS and ANS predicted cardinal knowledge in concert early in the school year, inconsistent with single‐mechanism models. The ANS but not the OTS predicted cardinal knowledge later in the school year as well the acquisition of the cardinal principle, a critical shift in cardinal understanding. The results support a Merge model, whereby both systems initially contribute to children's early mapping of number words to cardinal value, but the role of the OTS diminishes over time while that of the ANS continues to support cardinal knowledge as children come to understand the counting principles.  相似文献

While previous research has demonstrated that status significantly affects consumer behaviour, most studies have examined objective status rather than perceived status. The present article, therefore, aims to examine how a perceived change in status affects consumers’ status consumption as well as the underlying psychological mechanisms for this behaviour. Study 1 manipulates participants’ perceived status change and measures their tendencies toward status consumption. Results show that both participants undergoing status improvement and those perceiving a threat to their status are more inclined towards status consumption than participants in a control condition. Study 2 manipulates participants’ perceived status change and measures their self‐presentation motivation, self‐compensation motivation, and status consumption tendency. A series of mediation analyses shows that self‐presentation, rather than self‐compensation, mediates the positive effect of status improvement on consumers’ status consumption and that self‐compensation, rather than self‐presentation, mediates the positive effect of status threat on consumers’ status consumption. Results of our studies suggest that consumers who perceive status improvement seek status consumption for self‐presentation purposes, while consumers who perceive status threat seek status consumption for self‐compensation. The article concludes by discussing the theoretical contribution of this research and offering practical suggestions regarding product marketing.  相似文献

This study investigated the relationships between reciprocal filial piety beliefs, emotional intelligence, and life satisfaction among Taiwanese young adults. A total of 481 college students from Taiwan were recruited for the study. Structural equation modelling was employed to analyze the data. The analysis produced the following results. First, reciprocal filial piety was positively related to all of the four types of emotional intelligence: self‐emotional appraisal (SEA), others' emotional appraisal (OEA), regulation of emotion (ROE), and use of emotion (UOE). Second, both ROE and UOE had a positive association with life satisfaction whereas SEA and OEA had a nonsignificant association with life satisfaction. Third, the two types of emotional intelligence, ROE and UOE, mediated the relation between reciprocal filial piety and young adults' life satisfaction. The findings suggest that reciprocal filial piety, representing high‐quality interaction between children and parents, can facilitate individuals' ability to control and use their emotions, which in turn improves their life satisfaction.  相似文献

In recent years, schools have started implementing preventive practices such as universal screening. Yet, researchers have not evaluated the extent to which universal screening contributes to academic and behavioral outcomes. The purpose of this study was to evaluate the treatment utility of universal screening for behavioral risk. Student participants were randomly assigned to two groups, corresponding to a different method of identification (office discipline referrals and universal screening). Participants identified as at risk, based on their office discipline referral data or universal screening data, and selected for intervention, received a Tier 2 intervention. Data were analyzed using a fixed-effects regression model. Analyses identified no statistically significantly differences between the two groups with regard to various academic and behavioral outcomes, suggesting universal screening did not contribute to changes in student functioning.  相似文献
