Objectives“Stereotype threat” occurs when people perform worse at a task due to the pressure of a negative stereotype of their group's performance. We examined whether female athletes may underperform at an athletic task if prompted to think about gender stereotypes of athleticism. We also explored whether gender stereotypes regarding general athletic ability would be affected by a standard stereotype threat induction.DesignWe used a 2 (participant gender) × 2 (stereotype threat manipulation) factorial design with task performance and gender stereotypes of athleticism as dependent measures.MethodFemale and male tennis and basketball college student athletes performed two athletic tasks relevant to their sport: a difficult concentration task and an easier speed task. Participants were told beforehand that (1) there was a gender difference on the tasks (to induce stereotype threat) or (2) there was no gender difference (to remove any preexisting stereotype threat).ResultsOn the difficult task, women performed worse than men only when stereotype threat was induced. Performance on the easier speed task was unaffected by the stereotype information. Interestingly, women's beliefs regarding women's and men's general athleticism were also affected by the manipulation.ConclusionsWe concluded that one minor comment regarding a very specific athletic task may sometimes impair task performance and alter gender stereotypes of athleticism among women. Some implications for preventing negative stereotype threat effects are discussed.  相似文献

We investigated the effects of anxiety on the execution of police officers' arrest and self-defense skills. Police officers (n=13) performed three tasks in which they kicked, blocked, or restrained an opponent who attacked them with a rubber knife (low anxiety, LA) or a shock knife (high anxiety, HA) in a within-subject design. We analyzed performance (on a 5-point Likert scale), movement times, posture, and movement velocity and acceleration. Results revealed that performance was worse in the HA compared to the LA condition. Furthermore, analysis of full-body movement showed that under increased anxiety, police officers' performance contained characteristics of avoidance behavior, such as faster reactions (to reduce the time being exposed to the threat), leaning further backward (kick), and ducking down (block). In line with recent theoretical developments, it appears that under increased anxiety, police officers were less able to inhibit stimulus-driven processing (fear of getting hit) and enforce goal-directed processing (perform the skill as well as possible) leading to avoidance behavior and a decrease in performance.  相似文献

The results of the fourth cycle of the Program for International Student Assessment (PISA) revealed that an unacceptably large number of adolescent students in two states in India—Himachal Pradesh and Tamil Nadu—have failed to acquire basic skills in reading, mathematics, and science (Walker, 2011). Drawing on data from the PISA 2009 database and employing multivariate left-censored tobit regression as a data analytic strategy, the present study, therefore, examined whether or not the learning strategies—memorization, elaboration, and control strategies—of adolescent students in Himachal Pradesh (N = 1,616; Mean age = 15.81 years) and Tamil Nadu (N = 3,210; Mean age = 15.64 years) were linked to their performance on the PISA 2009 reading, mathematics, and science assessments. Tobit regression analyses, after accounting for student demographic characteristics, revealed that the self-reported use of control strategies was significantly positively associated with reading, mathematical, and scientific literacy of adolescents in Himachal Pradesh and Tamil Nadu. While the self-reported use of elaboration strategies was not significantly associated with reading literacy among adolescents in Himachal Pradesh and Tamil Nadu, it was significantly positively associated with mathematical literacy among adolescents in Himachal Pradesh and Tamil Nadu. Moreover, the self-reported use of elaboration strategies was significantly and positively linked to scientific literacy among adolescents in Himachal Pradesh alone. The self-reported use of memorization strategies was significantly negatively associated with reading, mathematical, and scientific literacy in Tamil Nadu, while it was significantly negatively associated with mathematical and scientific literacy alone in Himachal Pradesh. Implications of these findings are discussed.  相似文献

The aim of the present study was to explore the ability of personality to predict academic performance in a longitudinal study of a Swedish upper secondary school sample. Academic performance was assessed throughout a three‐year period via final grades from the compulsory school and upper secondary school. The Big Five personality factors (Costa & McCrae, 1992 ) – particularly Conscientiousness and Neuroticism – were found to predict overall academic performance, after controlling for general intelligence. Results suggest that Conscientiousness, as measured at the age of 16, can explain change in academic performance at the age of 19. The effect of Neuroticism on Conscientiousness indicates that, as regarding getting good grades, it is better to be a bit neurotic than to be stable. The study extends previous work by assessing the relationship between the Big Five and academic performance over a three‐year period. The results offer educators avenues for improving educational achievement.  相似文献

Although theoretical arguments suggest that impression management should be related to job performance, empirical results have been unsupportive of the association. We argue that this relationship, however, may be found for specific jobs (sales) using a specific objective criterion (sales revenue). We tested this hypothesis across two samples. The first sample utilized a concurrent design and found a significant association between impression management and objective job performance. Furthermore, impression management demonstrated incremental validity over conscientiousness. In the second sample, using a different impression management scale and a predictive design we found that impression management was related to sales revenue, and showed incremental validity over cognitive ability. Implications for research and practice are discussed.  相似文献

This study aimed to identify biographical and behavioral factors associated with children pianists’ motor skills using an objective assessment of a music-relevant motor task. Motor skills at the piano were assessed in 30 children pianists by measuring temporal unevenness in standardized scale playing using musical instrument digital interface (MIDI)-based scale analysis. Questionnaires were used to collect detailed information about the amount of time playing the piano, practice characteristics, attitudes toward music and practice, and the environment of music and practice. Associations between performance values and variables from the questionnaire were investigated using multivariable linear regression. A higher number of years playing the piano, more frequent parental involvement in the child’s practice, more frequent practice of technical exercises, and greater enjoyment of practice and of the visual arts were associated with better motor performance. In addition to cumulative experience and aspects of practice, extrinsic motivational factors (e.g., parental interest) and intrinsic motivational factors (e.g., an artistic disposition) were associated with better performance on a musically-relevant motor task in children pianists.  相似文献

PurposeWe examined links between the kinematics of an opponent’s actions and the visual search behaviors of badminton players responding to those actions.MethodA kinematic analysis of international standard badminton players (n = 4) was undertaken as they completed a range of serves. Video of these players serving was used to create a life-size temporal occlusion test to measure anticipation responses. Expert (n = 8) and novice (n = 8) badminton players anticipated serve location while wearing an eye movement registration system.ResultsDuring the execution phase of the opponent’s movement, the kinematic analysis showed between-shot differences in distance traveled and peak acceleration at the shoulder, elbow, wrist and racket. Experts were more accurate at responding to the serves compared to novice players. Expert players fixated on the kinematic locations that were most discriminating between serve types more frequently and for a longer duration compared to novice players. Moreover, players were generally more accurate at responding to serves when they fixated vision upon the discriminating arm and racket kinematics.ConclusionsFindings extend previous literature by providing empirical evidence that expert athletes’ visual search behaviors and anticipatory responses are inextricably linked to the opponent action being observed.  相似文献

In the current study, we investigated the role of three basic motivational needs (need for power, affiliation, achievement) as antecedents of goals within the 2 × 2 achievement goal framework, and examined their combined predictive validity with regard to academic performance in a sample of 120 university students. Structural equation modeling analysis largely supported our postulated model, linking motivational needs indirectly to course grades through goals. Achievement goals were formed by a combination of different motives: need for achievement was a positive predictor of all four achievement goals, and need for affiliation was negatively related to performance-approach and performance-avoidance goals. Additionally, need for power was a positive predictor of performance-avoidance goals. Performance-approach goals had a direct (positive) effect on performance outcomes. In sum, our results integrate basic motivational needs with the achievement goals literature and extend therefore hierarchical achievement motivation models, by showing how basic human motives of achievement, affiliation, and power are related to goal striving motivation and performance outcomes in an academic setting.  相似文献

In a quasi-experimental study, we examined the role of individual differences in the elicitation of emotional states in university examinations. Specifically, we assessed emotional states (a) before the first examination (baseline), (b) after receiving positive or negative feedback, and (c) then, again, before a series of subsequent examinations. We also measured effort in examination preparation and interest for studying. Data were collected during a university course that consisted of seven examinations in one semester; and 94 female students completed the BIS/BAS scales and SPSRQ (to measure sensitivity to punishment, SP, and reward, SR). Results revealed that higher BAS, but not SR, individuals experienced higher positive affect (PA) following positive feedback and they also showed higher levels of interest in studying. More generally, higher BIS and SP individuals experienced higher level of negative affect (NA) and they invested more effort in examination preparation; and both higher levels of SP and SR correlated positively with NA after receiving negative feedback. In addition, following negative feedback, higher BAS individuals experienced lower levels of PA, and higher SR individuals invested less effort in examination preparation. Results are discussed in terms of the reinforcement sensitivity theory (RST) of personality and directions for future research.  相似文献

道德型领导是新近提出的一种领导理论,大量研究证实这种领导方式会对员工和组织带来积极影响。然而,在领导过程中处于主体地位的领导者从中获得了什么收益却较少受到关注。以50个工作团队的248名员工为研究对象,本研究基于社会交换理论考察了道德型领导与个体层次和团队层次上领导者收益的关系及其作用过程。跨层次分析结果表明:(1)道德型领导对个体层次的员工对领导的认知信任和情感信任,以及团队层次的团队绩效和领导者绩效均有显著正向作用;(2)团队平均领导-部属交换中介了道德型领导与下属对领导者的认知信任、情感信任以及团队绩效的关系,但在道德型领导与领导者绩效关系间无显著中介作用。本文揭示了道德型领导者在领导过程中获得的“收益”以及团队层次社会交换的中介作用,为道德型领导和团队社会交换的研究提供了启示。  相似文献
