Music has the potential to evoke strong emotions and plays a significant role in the lives of many people. Music might therefore be an ideal medium to assess emotion recognition. We investigated emotion recognition in music in 20 patients with idiopathic Parkinson’s disease (PD) and 20 matched healthy volunteers. The role of cognitive dysfunction and other disease characteristics in emotion recognition was also evaluated. 相似文献

This paper describes the predictive power of the Suicide Probability Scale (SPS) within a male inmate population. The SPS scores of 1,047 inmates from 1995 to 1996 were compared against their suicidal behaviors in the following 10 years. The SPS probability score and the scores on its four subscales were found to be significantly higher in the group that engaged in
at least one of three types of suicidal behavior: suicide, non-lethal self-harm and serious suicidal intentions. However,
the SPS did not discriminate the inmates who went on to commit suicide. The SPS’s capacity to predict suicidal behavior proved limited in terms of sensitivity. In this regard, the SPS’s low and high risk levels correctly identified 36% of inmates who later engaged in suicidal behavior. The specificity was
0.85. These results confirm the SPS’s predictive power with male prisoners. These findings are the first to demonstrate the predictive validity of the SPS. 相似文献

Building on conservation of resources theory and the dynamic equilibrium model, this three‐wave longitudinal study among 260 Dutch agricultural business owners (1‐year time intervals) investigated reciprocal relationships between the financial situation of the business and psychological distress. Results of structural equation modelling analyses revealed a negative spiral of farm decline, in which psychological variables played a key role. Experiencing financial problems predicted psychological distress, and acted as a self‐fulfilling prophecy by strengthening intentions to quit the business, which predicted a deterioration of the objective financial situation of the business 1 year later. Moreover, farmers experiencing more psychological distress were more likely to get caught in this negative spiral than business owners with better mental health, because they experienced more financial problems, irrespective of their objective financial situation. Long‐term psychological distress rather than temporary fluctuations in distress levels accounted for this effect. 相似文献

This study investigated how leader–member exchange (LMX), goal setting, and feedback are related to employee engagement in learning activities. Two different mechanisms were proposed: a mediating mechanism holding that LMX elicits specific leader behaviours (i.e., goal setting and feedback) which would mediate the LMX‐learning relationship, and a moderating mechanism, holding that LMX would strengthen the effect of these leader behaviours. A sample of 1,112 employees from 7 organizations completed questionnaires that measured LMX, goal specificity, feedback, and self‐reports of employee engagement in learning activities. The 233 direct leaders of these employees completed questionnaires that measured goal difficulty and leader ratings of employee engagement in learning activities. Multi‐level analysis showed that goal difficulty and goal specificity mediated the relationship between LMX and employee engagement in learning activities, and that LMX moderated the relationship of goal difficulty with employee engagement in learning activities. With these findings, the present study contributes to the literatures on LMX, goal setting, and employee development. 相似文献

Cognitive conflict plays an important role in tuning cognitive control to the situation at hand. On the basis of earlier findings demonstrating emotional modulations of conflict processing, we predicted that affective states may adaptively regulate goal-directed behavior that is driven by conflict. We tested this hypothesis by measuring conflict-driven control adaptations following experimental induction of four different mood states that could be differentiated along the dimensions of arousal and pleasure. After mood states were induced, 91 subjects performed a flanker task, which provided a measure of conflict adaptation. As predicted, pleasure level affected conflict adaptation: Less pleasure was associated with more conflict-driven control. Arousal level did not influence conflict adaptation. This study suggests that affect adaptively regulates cognitive control. Implications for future research and psychopathology are discussed. 相似文献

This study is an investigation of the impact of familial amyloid polyneuropathy type I (FAP I, ATTR V30M) on death anxiety
and symbolic immortality. Templer and Drolet’s scales were administered to 524 individuals: (1) 84 relatives at risk, (2)
92 relatives not at risk for FAP I; and (3) a control group (n = 348) with no known hereditary disease in their families. At-risk relatives had, on average, a higher score for death anxiety
and a lower score for symbolic immortality, than either those not-at-risk or controls. There were no significant differences
in scores on either measure for those not-at-risk versus controls. Being at risk increases death anxiety and threatens the
sense of symbolic immortality and psychosocial wellbeing. This may be true for other serious hereditary disorders as well.
Genetic counsellors should become familiar with these concepts, feel comfortable initiating discussions about death with their
patients, and be able to identify and reinforce their patients’ and family members’ sense of symbolic immortality. 相似文献

Cannabinoid CB1 receptor (CB1R) signaling has been suggested to play an important role in the regulation of memory and cognition. In the present study, our aim was to investigate whether the CB1R antagonist SLV330 (doses ranging from 0.3 to 10 mg/kg, given orally, p.o.) could ameliorate impairments in distinct aspects of cognition using different disruption models in both mice and rats. Effects of SLV330 were tested on working memory deficits in the T-maze Continuous Alternation Task (T-CAT) in mice; episodic memory deficits in the Object Recognition Task (ORT) and Social Recognition Task (SRT) in rats. The acetylcholinesterase inhibitor (AChEI) donepezil (Aricept®, approved for symptomatic treatment of Alzheimer’s disease) and nicotine were used as reference compounds.SLV330 markedly improved aging and scopolamine-induced memory deficits in the T-CAT in mice with a lowest effective dose (LED) of 1 mg/kg p.o., while reversing the cognitive dysfunction induced by the N-methyl-d-aspartate (NMDA) antagonist dizocilpine (MK-801) only at the middle dose of 3 mg/kg. In the ORT, we have found that combined administration of subthreshold doses of SLV330 (1 mg/kg, p.o.) and the AChEI donepezil (0.1 mg/kg, p.o.), that had no discernable effects on performance when given alone, enhanced memory performance in Wistar rats with deficits induced by the muscarinic antagonist scopolamine, suggestive of additive synergistic effects of SLV330 and donepezil on cognitive impairment. Finally, SLV330 was found to have cognition enhancing properties in a time delay paradigm in the SRT at a LED dose of 3 mg/kg (p.o.).In conclusion, the CB1R antagonist SLV330 was found to clearly improve memory in several preclinical models for cognitive impairment. 相似文献

The aim of this essay has been the evaluation of three orientations towards happiness: pleasure, meaning and engagement, as well as their relation to life satisfaction and the perception of happiness in a sample of 320 university students. The results show that the most used kind of orientation towards happiness is pleasure, followed by meaning, and finally engagement. It has also been found that pleasure is the orientation most closely associated to happiness while engagement seems to be more related to life satisfaction. These findings aim to the distinction between the concepts of happiness and life satisfaction and lead the attention to the actions which can improve the levels of happiness. 相似文献

Motivational characteristics are influential in shaping adolescents' desire to persist in sport or to discontinue their sport participation. Self-determination theory (Deci & Ryan, 2000) was utilized as the theoretical framework for this study. This theory examines whether sustained participatory involvement, defined as continued participation in the sport through the next year, was influenced by individuals' self-determined motivation and by the fulfillment of the three basic psychological needs of autonomy, competence, and relatedness. Four hundred ninety two soccer players between the ages of 13 and 17 years comprised the sample. Results indicated sport dropout was explained by higher levels of amotivation, external regulation, and introjected regulation and by lower satisfaction of relatedness and autonomy needs. The findings of this study contribute to the knowledge base on sport dropout as they supported many of self-determination theory. 相似文献
