This study investigated whether Coping Motivated and Enhancement Motivated drinkers differ in their degree of semantic activation of alcohol concepts on a primed Stroop colour-naming task following exposure to negative and positive affect primes, respectively. Participants were 48 undergraduates (not necessarily problem drinkers) who had elevated scores on the Coping Motivated or Enhancement Motivated subscale of the Drinking Motives Questionnaire - Revised. The Stroop task involved negative, positive and neutral primes that preceded alcohol and no-alcohol target words. As hypothesized, Coping Motivated drinkers showed semantic activation of alcohol concepts following exposure to negative but not neutral primes. Also as hypothesized, Enhancement Motivated drinkers showed semantic activation of alcohol concepts following exposure to positive but not negative primes. Unexpectedly, semantic activation of alcohol concepts was also observed among Coping Motivated drinkers following positive primes and among Enhancement Motivated drinkers following neutral primes. Theoretical implications are discussed, as are implications for improving cognitive behavioral interventions for problem drinkers.  相似文献

Employees' personal initiative (i.e., their active and future-oriented engagement at work) is of high relevance to organizations that strive for innovation and competitiveness. To better understand its drivers and diminishers, the present study refers to Affective Events Theory and examines the impact of leader emotion management, team conflict, and affective well-being on personal initiative. Data from 300 members of 59 work teams in Germany were gathered from multiple sources at three points in time over the course of 2 weeks. Multilevel analyses indicated that leader emotion management positively affected team members' personal initiative and that this effect was mediated by team members' affective well-being. Data also revealed a contrasting negative indirect effect of task conflict within the team on team members' personal initiative via team members' affective well-being. The study's results suggest that the improvement of leaders' emotion management as well as the establishment of work conditions and experiences that foster affective well-being should be seriously considered by organizations wishing to facilitate personal initiative in team settings.  相似文献

Transactive memory theory suggests that general awareness of expertise location in a group is sufficient to predict expertise seeking. Yet expertise seeking is, at least in part, a social phenomenon between two individuals embedded in a network of social relationships. Taking a multilevel, network perspective, we examined the interplay of affective relationships and awareness on expertise seeking in groups. Hypotheses were tested using network data collected from 693 employees in 53 sales groups. HLM analysis results indicated that awareness of expertise distribution positively influenced the decision to seek expertise at all levels of analysis examined. In addition, both positive and negative affective relationships influenced expertise seeking, although their pattern of influence differed across different levels of analysis. More specifically, having either a positive or a negative affective relationship with another group member affected the decision to seek expertise from that person. Although having many positive relationships had a positive effect on expertise seeking, having many negative affective relationships had no effect. Moreover, having both an awareness and a positive affective relationship with another group member amplified their positive effect on expertise seeking. Last, individuals who had more negative affective ties were less likely to leverage the positive impact of each awareness relationship on expertise seeking.  相似文献

Measures of religiosity validated for psychotic patients do not exist. This study sought to examine the psychometric properties of a modified version of the Religious Life Inventory (RLI) in this population. It was anticipated that religiosity would be affected by psychotic symptoms. The religiosity of patients with schizophrenia was assessed while symptoms were more evident and again after treatment, to evaluate changes in religiosity. Four factors were found which characterized the religiosity of people with schizophrenia. These factors were found to have good construct validity. Patient's responses indicated a reduced need for religion when re-assessed once symptom scores were reduced.  相似文献

When letters are encountered, two spatial stimulus codes resulting from their positions within the alphabet and on the computer keyboard are activated mentally. If these two spatial codes match, letter processing is more efficient. The present study tested whether the processing fluency gain resulting from alphabet–keyboard compatibility also enhances affective evaluations of letters. In Experiment 1, participants preferred alphabet–keyboard compatible over incompatible letters in a forced-choice preference rating. Similarly, in Experiment 2, liking ratings for alphabet–keyboard compatible letters were higher compared to incompatible letters. Moreover, in Experiment 3, preference ratings of non-words were positively correlated with the relative number of alphabet–keyboard compatible letters within these letter strings. These findings suggest that alphabet–keyboard compatibility shapes the affective connotation of letters. Moreover, this processing fluency–valence association is activated at the level of letters as well as whole letter strings.  相似文献

The recording of event-related potentials (ERPs) in the brain has allowed for a better understanding of human sensory and cognitive processing. This technique may also prove useful in studying implicit social attitudes and their effects on information processing. Here, ERPs were used in a study of "hot cognition" in the context of political concepts. Hot cognition, as applied to the political domain, posits that all sociopolitical concepts that have been evaluated in the past are affectively charged, and that this affective charge is automatically activated from long-term memory within milliseconds of presentation of the political stimulus. During an evaluative priming task, ERP recordings showed that affectively incongruent prime/target pairs elicited an enhanced negativity with a peak latency of about 400 milliseconds relative to affectively congruent prime/target pairs. These differences suggest that automatic, implicit evaluations were made in response to strongly positive and negative political stimuli, and that these evaluations affected the subsequent processing of a high-valence adjective. Therefore, it appears that the emotional valence of a political prime is stored along with the concept itself, and that an affective response becomes active upon mere exposure to the political stimulus.  相似文献

Logic Games are Complete for Game Logics   总被引:1,自引:0,他引:1  
van Benthem  Johan 《Studia Logica》2003,75(2):183-203
Game logics describe general games through powers of players for forcing outcomes. In particular, they encode an algebra of sequential game operations such as choice, dual and composition. Logic games are special games for specific purposes such as proof or semantical evaluation for first-order or modal languages. We show that the general algebra of game operations coincides with that over just logical evaluation games, whence the latter are quite general after all. The main tool in proving this is a representation of arbitrary games as modal or first-order evaluation games. We probe how far our analysis extends to product operations on games. We also discuss some more general consequences of this new perspective for standard logic.  相似文献

We examined enrichment and stress in 214 families who had children with severe emotional disorders. Caregivers' ratings of enrichment and stress were obtained through a newly developed instrument, the Effects of the Situation Questionnaire, which used parallel items covering 17 life areas. While ratings of stress were generally higher than enrichment, caregivers reported some enrichment in areas encompassing self concept and family relationships, Bivariate and multivariate analyses using various child, family, and service-system variables revealed that stress was notably associated with severity of the child's disorder, low empowerment, and a lack of coordination among service providers. Enrichment was unrelated to severity but associated with high empowerment and spiritual support. Our findings suggest that families' experiences of caregiving can have both positive and negative aspects and that a comprehensive approach to serving and studying families should take both into account.  相似文献

Transient ischaemic attack (TIA) is often associated with anxiety and depression, which may precipitate secondary stroke and interfere with treatment. The Hospital Anxiety and Depression Scale (HADS) is widely used to assess these states and to inform the management of any associated psychological problems, but there is considerable debate about what it actually measures. The HADS scores from a range of different clinical groups have been reviewed in order to assess its psychometric properties, but so far, no research has examined either its latent structure when used with TIA patients, or the association between symptom severity and the test’s validity. The aims of this study, therefore, were to investigate: (a) the underlying structure of the HADS when used with TIA patients; and (b) the impact of symptom severity on the validity of the HADS. The HADS and a functional capacity measure were administered by post to a sample of 542 confirmed TIA patients. Exploratory factor analysis was conducted on the HADS scores to establish its underlying structure for this clinical group, and then, sub-sample correlations were undertaken between the anxiety/depression scores for different levels of functional capacity. Two factors emerged, with 13 of the 14 HADS items loading significantly on both, suggesting there is a common affective state underlying the standard anxiety and depression scales. Further data-exploration indicated that convergence between these affective states increased as functional capacity deteriorated. The results suggest firstly that the HADS measures general subjective distress when used with TIA patients, and secondly that the higher reported symptom severity in this clinical group may be associated with reduced affective differentiation. As the ability to retain clear affective discrimination is associated with health and well-being, this could provide a focus for post-TIA rehabilitation.  相似文献
