The purpose of this study was to assess the predictive validity of observer ratings of personality and job-related competencies in a selection setting. Based on ratings from multiple raters of both the predictors and the criteria in a sample of MBA students, results indicated that observer ratings of Conscientiousness, Emotional Stability, leadership, and interpersonal skills predicted work performance, team performance, and academic performance. For work performance and team performance, a composite of the four predictors had incremental predictive validity over general mental ability, even after controlling for how well the rater knew the ratee. 相似文献

Although absolute pitch (AP) is a rare skill in typical development, individuals with Williams syndrome (WS) are often referred to as possessing this musical ability. However, there is paucity of research on the topic. In this article, 2 studies were conducted to evaluate AP in WS. In Study 1, seven musically trained individuals with WS, 14 musically trained typically developing controls matched for chronological age, and 2 experienced musicians with AP completed a pitch-identification task. Although the task was a classical assessment of AP, it required participants to have musical knowledge, and the availability and accessibility of musically trained individuals with WS is very low. In Study 2, a paradigm suitable for evaluating AP in individuals without musical training was used, which made it possible to evaluate a larger group of participants with WS. A pitch memory test for isolated tones was presented to 27 individuals with WS, 54 typically developing peers matched for chronological age, and the 2 musicians with AP. Both individuals with WS and their controls obtained low results in the two studies. They showed an arbitrary pattern of response, and their performance was far from that of musicians with AP. Therefore, participants with WS did not appear to possess AP. Unlike what is usually claimed, results suggest that AP is not a remarkable ability in WS and that, as in the typically developing population, this musical ability is also rare in individuals with WS. 相似文献

Previous studies have shown that children and adolescents often tend toward risky decisions despite explicit knowledge about the potential negative consequences. This phenomenon has been suggested to be associated with the immaturity of brain areas involved in cognitive control functions. Particularly, “frontal lobe functions,” such as executive functions and reasoning, mature until young adulthood and are thought to be involved in age-related changes in decision making under explicit risk conditions. We investigated 112 participants, aged 8–19 years, with a frequently used task assessing decisions under risk, the Game of Dice Task (GDT). Additionally, we administered the Modified Card Sorting Test assessing executive functioning (categorization, cognitive flexibility, and strategy maintenance) as well as the Ravens Progressive Matrices assessing reasoning. The results showed that risk taking in the GDT decreased with increasing age and this effect was not moderated by reasoning but by executive functions: Particularly, young persons with weak executive functioning showed very risky decision making. Thus, the individual maturation of executive functions, associated with areas in the prefrontal cortex, seems to be an important factor in young peoples’ behavior in risky decision-making situations. 相似文献

The cross-cultural generalizability of the Personality and Role Identity Structural Model (PRISM; Wood & Roberts, 2006) was tested in the United States, Mexico, Malaysia, China, and Japan. Participants rated their general and role identities, as defined by the PRISM, using Big Five trait adjectives, then rated their personality states (i.e., role experiences) in various roles in multiple daily interactions for 14 days. Structural predictions based on the PRISM were supported in all five cultures. Cultural differences were limited and did not reflect cultural differences in individualism–collectivism, dialecticism, or cultural tightness. The results supported the cross-cultural generalizability of the PRISM and the merits of contextualized trait measures in the prediction of role experiences. Implications for trait and cultural psychology are discussed. 相似文献

This paper is dedicated to Alonzo Church, who died in August 1995 after a long life devoted to logic. To Church we owe lambda calculus, the thesis bearing his name and the solution to the Entscheidungsproblem.His well-known book Introduction to Mathematical LogicI, defined the subject matter of mathematical logic, the approach to be taken and the basic topics addressed. Church was the creator of the Journal of Symbolic Logicthe best-known journal of the area, which he edited for several decades This paper is in three sections. The first is written in journalistic style:the story of the life of AlonzoChurch is told, including some of the many anecdotes I have collected from different sources. The secondpart is devoted to his work, but is far from being exhaustive. The last part is more original; in it I attempto show that Church’s great discovery was lambda calculus and that his remaining contributions weremainly inspired afterthoughts in the sense that most of his contributions as well as some of his pupils derivefrom that initial achievement. Included are Kleene’s Recursion Theory and the completeness proof ofHenkin. I have added an appendix in which is presented the typed lambda calculus and a proof of theundecidability of first-order logic 相似文献

The aim of this study was to investigate the effect of advanced age on self-reported internal and external memory strategy uses, and whether this effect can be predicted by executive functioning. A sample of 194 participants aged 21 to 80 divided into three age groups (21-40, 41-60, 61-80) completed the two strategy scales of the Metamemory in Adulthood (MIA) questionnaire, differentiating between internal and external everyday memory strategy uses, and three tests of executive functioning. The results showed that: (1) the use of external memory strategies increased with age, whereas use of internal memory strategy decreased; (2) executive functioning appeared to be related only to internal strategies, the participants who reported the greatest use of internal strategies having the highest executive level; and (3) executive functioning accounted for a sizeable proportion of the age-related variance in internal strategy use. These findings suggest that older adults preferentially use external memory strategies to cope with everyday memory impairment due to aging. They also support the view that the age-related decrease in the implementation of internal memory strategies can be explained by the executive hypothesis of cognitive aging. This result parallels those observed using objective laboratory memory strategy measures and then supports the validity of self-reported memory strategy questionnaire. 相似文献

The aims of the present study were twofold: assessing the prevalence and intensity of post‐traumatic stress disorder (PTSD) symptoms in victims of bullying, and exploring whether victims of bullying differ in their basic assumptions compared to a control group. A total of 183 victims of bullying and 183 control group participants took part in the research. The results showed that 42.6% of the total sample met all DSM‐IV‐TR criteria for PTSD, whereas 54.1% did not fulfill the A1 criterion. Post‐traumatic symptoms were more prevalent among women (49%), as compared to men (35.3%). Furthermore, victims showed significantly more negative beliefs about the world, the people, and themselves, compared to their non‐bullied controls. These results fit well with cognitive theory of trauma. 相似文献

Three experiments were conducted to explore the effects of different interference treatments upon outcome-specific transfer from predictive learning to instrumental responding. A computer game was designed in which participants had to defend Andalusia from navy and air-force attacks. Participants learned the relationship between two instrumental responses (two keys in a standard keyboard) and two different outcomes (destruction of the ships or destruction of the planes). Then, they learned to predict which of two different cues predicted either outcome. Finally, participants were allowed to give either of the two instrumental responses in the presence of each cue. Outcome-specific transfer was shown as a preference for the response that shared the outcome with the current cue. Extinction of the cue before the transfer test had no effect upon transfer, regardless of the level of extinction (Experiments 1-3). However, pairing the cue with the alternative outcome (counterconditioning) reversed the outcome-based transfer effect (Experiment 3). The implications of these results for the contents of extinction in human predictive learning are discussed. 相似文献

To analyze the psychometric properties of the Coping Response Inventory-Youth Form (CRI-Y) and its applicability, 426 Brazilian adolescents (43.3% boys, 56.7% girls), ages 12 to 18 years (M = 16.5, SD = 1.6), completed the authorized Brazilian/Portuguese version of the 1993 original. Analysis showed higher use of Approach coping and Emotional Discharge by the girls. The inventory showed internal consistency reliability was similar to that of the original scale. A two-factor structure reflecting Approach and Avoidance coping was found; however, the distribution of loadings of specific coping scales on this two-factor structure did not fit the original Moos model. The criterion validity analyzed by the use of the Youth Self-Report showed significant positive relation between the Avoidance dimension and Psychopathological symptoms for boys and girls. Data were discussed with respect to coping theory, assessment, and cultural influences. 相似文献

The effect of explicitly providing goalkeeper's movement advanced cue to the kicker during a real penalty kick task was assessed. 32 expert soccer players (M age= 23.2 yr.), who were divided into four groups: an experimental group, a discovery group, a placebo group, and a control group, participated. Rate of success in the task was assessed, as well as goals, decision times, and ball flight times. Providing an advance cue significantly improved the players' rate of success relative to players without the advance cue; this difference was still present after 1 and 7 days without training. The experimental group adapted better to the time range within which the response could be effective, while the discovery group showed adaptations. Explicit instructions about the advance cues available from goalkeepers' actions before the dive during practice can improve penalty kick performance. 相似文献
