We examined the categorical nature of emotion word recognition. Positive, negative, and neutral words were presented in lexical decision tasks. Word frequency was additionally manipulated. In Experiment 1, “positive” and “negative” categories of words were implicitly indicated by the blocked design employed. A significant emotion–frequency interaction was obtained, replicating past research. While positive words consistently elicited faster responses than neutral words, only low frequency negative words demonstrated a similar advantage. In Experiments 2a and 2b, explicit categories (“positive,” “negative,” and “household” items) were specified to participants. Positive words again elicited faster responses than did neutral words. Responses to negative words, however, were no different than those to neutral words, regardless of their frequency. The overall pattern of effects indicates that positive words are always facilitated, frequency plays a greater role in the recognition of negative words, and a “negative” category represents a somewhat disparate set of emotions. These results support the notion that emotion word processing may be moderated by distinct systems.  相似文献

In coincidence‐timing studies, children have been shown to respond too early to slower stimuli and too late to faster stimuli. To examine this velocity effect, children aged 6, 7.5, 9, 10.5, and adults were tested with two different velocities in a prediction‐motion task which consisted of judging, after the occlusion of the final part of its path, the moment of arrival of a moving stimulus towards a specified position. A similar velocity effect, resulting in later responses for the faster velocities than for the slower, was found primarily in the three younger groups of children (for the longer occlusion conditions: 600–1,320 milliseconds). However, this effect was not seen in all children in these groups. Individual analyses showed that this velocity effect, when present, is linked to the use of distance rather than time information, or to the confusion between these in extrapolating the occluded trajectories. The tendency to use one type of information or the other is a good predictor of accuracy and variability in this task and a good indicator of the development stage of the participants. Across development, children tend to initially use distance information with poor accuracy but relative consistency in responses. In a second stage, they use time and distance information alternatively across trials trying to find a better source of information with still poor accuracy and now great variability. In a final stage, they use time information to reach consistency and accuracy in their responses. This chronology follows the stages proposed by Savelesbergh and Van der Kamp (2000) explaining development with an initial stage of ‘freezing’ non‐optimal relationships between information and movement, then a ‘freeing’ stage during which new solutions are searched for, and finally an ‘exploiting’ stage with an optimal relationship between information and movement.  相似文献

The current study's aims are twofold: first, we investigate the relationship between employability and both work‐related (engagement) and general (life satisfaction) well‐being. Second, we study how employability may be relevant in times of high job insecurity. Specifically, we hypothesise (1) a positive relationship between employability and employees’ well‐being, (2) a negative relationship between employability and job insecurity, and (3) a negative relationship between job insecurity and employees’ well‐being, so that (4) job insecurity mediates the relationship between employability and employees’ well‐being. Results based on a sample of 559 respondents from divisions of seven Belgian organisations support our hypotheses. We conclude that employability may be a means to secure one's labour market position, rather than a means to cope with job insecurity. Les objectifs de cette étude sont doubles: nous étudions d’abord la relation entre l’employabilité et à la fois le bien‐être relatif au travail (implication) et le bien‐être global (la satisfaction provenant de l’existence). Ensuite, nous nous interrogeons sur la pertinence de l’employabilité en période de grande insécurité professionnelle. Plus précisément, nous posons les hypothèses 1) d’une relation positive entre l’employabilité et le bien‐être des employés, 2) d’une relation négative entre l’employabilité et l’insécurité professionnelle et 3) d’une relation négative entre l’insécurité professionnelle et le bien‐être des salariés, si bien que 4) l’insécurité professionnelle régule la relation entre l’employabilité et le bien‐être des salariés. Les résultats issus d’un échantillon de 559 répondants provenant de départements de sept organisations belges confortent nos hypothèses. On conclut que l’employabilité peut être une façon de sécuriser sa situation sur le marché du travail plutôt qu’un moyen pour affronter l’insécurité professionnelle.  相似文献

OBJECTIVE: Approximately 6,000 Americans die every year awaiting an organ transplant. Health promotion interventions may alleviate the shortage of viable organs by increasing the number of registered organ donors. This study is the first to evaluate the differential effectiveness of various organ donor messages in naturalistic settings. DESIGN: A 4 (Appeal)x4 (Exemplar)x4 (Location) counterbalanced quasi-experimental design was implemented. MAIN OUTCOME MEASURE: The behavioral outcome measure was the number of individuals who registered to be organ donors at computer kiosks. RESULTS: A number of significant main effects and interactions emerged. Most notably, of the 4 different appeals (counterargument, emotional, motivating action, dissonance), counterargument was by far the most efficacious, especially in academic-type settings (library, university, community college); the emotional appeal was most successful in hospitals. CONCLUSIONS: The findings from this study have implications for both organ donor investigations and health campaign research in general. Statistical interactions highlight the importance of evaluating multiple exemplars in multiple locations for each type of appeal when conducting health campaign research.  相似文献

This study aimed at the assessment of psychometric properties of the Italian version of the Spanish Burnout Inventory (SBI-Ita) in a sample of Italian teachers and the analysis of burnout profiles based on a model that includes four dimensions: Enthusiasm toward job, Psychological exhaustion, Indolence, and Guilt. A self-reported questionnaire was filled out by 689 Italian teachers. Data analyses performed Multi-sample Confirmatory Factor Analysis and Hierarchical Cluster Analysis. Results confirmed the hypothesized four-factor structure and the discriminant role of Guilt in differentiating clusters. Results highlights the reliability of the SBI-Ita in the assessment of teachers’ burnout. Furthermore, results evidence for a new typology of burnout that differentiate guilty from non-guilty professionals.  相似文献
