Optimism and the Big Five factors of personality: Beyond Neuroticism and Extraversion

The purpose of the present study was to investigate the relationship between the Big Five factors of personality and dispositional optimism. Data from five samples were collected (Total N = 4332) using three different measures of optimism and five different measures of the Big Five. Results indicated strong positive relationships between optimism and four of the Big Five factors: Emotional Stability, Extraversion, Agreeableness, and Conscientiousness. Agreeableness and Conscientiousness explained additional variance in dispositional optimism over and above Neuroticism and Extraversion, providing evidence for the complexity of optimism. The position of optimism in the larger web of human personality constructs is discussed.     

Positive affect increases cognitive control in the antisaccade task

To delineate the modulatory effects of induced positive affect on cognitive control, the current study investigated whether positive affect increases the ability to suppress a reflexive saccade in the antisaccade task. Results of the antisaccade task showed that participants made fewer erroneous prosaccades in the condition in which a positive mood was induced compared to the neutral condition (i.e. in which no emotional mood was induced). This improvement of oculomotor inhibition was restricted to saccades with an express latency. These results are in line with the idea that enhanced performance in the positive affect condition could be caused by increased dopaminergic neurotransmission the brain.     

Relationship between positive mental health and appreciation in Korean individuals

Appreciation is a key component of subjective well‐being and may contribute to positive mental health. Few studies have examined relationships between specific aspects of appreciation and the 3 dimensions of positive mental health, and thus, the aim of this study was to identify associations between aspects of appreciation and positive mental health. Appreciation and positive mental health were measured in 266 Korean university students (50% females) using the Appreciation Inventory and the Mental Health Continuum‐Short Form. The results obtained showed that Have Focus significantly predicted Emotional Well‐being; Have Focus and Loss/Adversity significantly predicted Social Well‐being and Have Focus, Expression and Nature/Daily Life significantly predicted Psychological Well‐being. The implications of results that might enable positive mental health to be enhanced are discussed.     

The effect of positive affect on conflict resolution: Modulated by approach-motivational intensity

The motivational dimensional model of affect proposes that the influence of positive affect on cognitive processing is modulated by approach-motivational intensity. The present research extended this model by examining the influence of positive affect varying in approach-motivational intensity on conflict resolution—the ability to resolve interference from task-irrelevant distractors in order to focus on the target. The global–local task (Experiment 1) and letter-Flanker task (Experiment 2) were used to measure conflict resolution. Additionally, the 4:2 mapping design that assigns two kinds of task-relevant stimuli to one response key and two more to another response key was used in these two tasks to dissociate stimulus and response conflict. Results showed that positive affect varying in approach motivation had opposite influences on conflict resolution. The opposite influences are primarily reflected in low approach-motivated positive affect impairing, while high approach-motivated positive affect facilitating the resolution of response conflict. Conversely, the stimulus conflict was slightly influenced. These findings highlight the utility of distinguishing stimulus and response conflict in future research.

情绪可以唤醒自主神经系统, 伴随有一系列的生理变化。从基础研究的角度来看, 正负性情绪可以诱发心血管系统(如心率、血压、心率变异性)、皮肤电系统(如皮肤电导水平)、呼吸系统(如呼吸阻力、每分通气量)和其他系统(如瞳孔直径、胃肌电等)的活动及其变化。在应用研究方面, 正负性情绪诱发的自主神经反应可以应用在多个领域, 主要包括用户体验中的情绪测量、基于生理信号的人-机情感交互系统的开发, 以及消费者态度和偏好的测查等。对于现有研究结果中存在的分歧, 从被试的个体差异、诱导范式的不一致性和诱导效果的可靠性, 以及刺激材料属性的多样化等方面进行了分析, 指出了未来研究应该注意的问题。     

Listeners influence speakers’ perceived communication effectiveness

People have an exaggerated sense of self-efficacy. This paper investigates the mechanism behind speakers’ tendency to overestimate their communication efficacy. Two competing mechanisms were tested: intrapersonal and interpersonal. Speakers communicated a series of ambiguous statements to a co-present or absent listener and then estimated their success. Speakers overestimated their ability to communicate their intended message (relative to listeners’ actual comprehension of their message) when a listener was co-present, but not when a listener was absent. Our findings support an interpersonal explanation of speakers’ perceived communication efficacy.     

Employee commitment and well-being: A critical review, theoretical framework and research agenda

Although a great deal is known about the implications of employee commitment for organizations, less attention has been paid to its ramifications for employees themselves. Previous research has been unsystematic and the findings have sometimes been inconsistent. The most consistent findings pertain to the positive links between affective commitment and employee well-being. Relations between continuance commitment and well-being are more variable, but generally negative. Little is known about relations involving normative commitment. There is considerable inconsistency in findings pertaining to the moderating effects of commitment on stressor-strain relations. We provide a theoretical framework based on an integration of the three-component model of commitment (Meyer & Allen, 1997) and Deci and Ryan's (1985) self-determination theory of motivation to help explain both the consistencies and inconsistencies, and to guide future research. We also argue for a broadening of the concept of employee well-being to include indices of eudaimonic as well as hedonic well-being.     

Resilience to suicidal ideation in psychosis: Positive self-appraisals buffer the impact of hopelessness

Recent years have seen growing interest into concepts of resilience, but minimal research has explored resilience to suicide and none has investigated resilience to suicide amongst clinical groups. The current study aimed to examine whether a proposed resilience factor, positive self-appraisals of the ability to cope with emotions, difficult situations and the ability to gain social support, could buffer against the negative impact of hopelessness amongst individuals with psychosis-spectrum disorders when measured cross-sectionally. Seventy-seven participants with schizophrenia-spectrum disorders completed self-report measures of suicidal ideation, hopelessness and positive self-appraisals. Positive self-appraisals were found to moderate the association between hopelessness and suicidal ideation. For those reporting high levels of positive self-appraisals, increased levels of hopelessness were significantly less likely to lead to suicidality. These results provide cross-sectional evidence suggest that positive self-appraisals may buffer individuals with psychosis against the pernicious impact of a well known clinical risk factor, hopelessness. Accounting for positive self-appraisals may improve identification of individuals at high risk of suicidality, and may be an important area to target for suicide interventions.     

Resilience as positive coping appraisals: Testing the schematic appraisals model of suicide (SAMS)

Aims

The Schematic Appraisals Model of Suicide (SAMS) suggests that positive self-appraisals may be important for buffering suicidal thoughts and behaviours, potentially providing a key source of resilience. The current study aimed to explore whether positive self-appraisals buffered individuals from suicidality in the face of stressful life events.

Method

78 participants who reported experiencing some degree of suicidality were recruited from a student population. They completed a battery of questionnaires including measures of suicidality, stressful life events and positive self-appraisals.

Results

Positive self-appraisals moderated the association between stressful life events and suicidality. For those reporting moderate or high levels of positive self-appraisals, raised incidence of stressful life events did not lead to increases in suicidality.

Discussion

These results support the SAMS framework, and suggest that positive self-appraisals may confer resilience to suicide. Positive self-appraisals may be a promising avenue for further resilience research, and an important area to target for suicide interventions.     

Associated Factors of Suicide Among University Students: Importance of Family Environment

The aim in this study was to underline the importance of family environment as a significant associate of suicide probability among university students. For this aim 226 Turkish university students completed Suicide Probability Scale, Family Environment Questionnaire, Beck Depression Inventory, and Positive and Negative Affect Scale. As a result of the formulated regression analysis, after controlling for the 51% of the total variance accounted for by the control variables (i.e., gender, age, living with family versus away from family, and Grade Point Averages) and mood related variables (i.e., depressive symptoms, and positive and negative affect), family cohesion still emerged as a significant associate of the suicide probability. These findings underline the importance of family relations as a risk factor of suicide among university students.This work has been supported by the Turkish Academy of Sciences, in the framework of the Young Scientist Award Program.
