We proposed that intermittent evaluations of performance could be used to promote the acquisition of a complex skill. We also hypothesized that trainees low in need for cognition (NFC) would benefit more from intermittent evaluations compared to trainees high in NFC. Accordingly, 106 young adult males participated in 5 h of training in order to learn a complex computer task that simulated the demands of a dynamic aviation environment. Trainees’ performance was assessed either intermittently during training or at the end of training. Results indicated that intermittent performance evaluations enhanced the skill-based learning of trainees low in NFC, whereas intermittent skill evaluations tended to undermine the skill-based learning of trainees high in NFC. The findings are discussed in relation to Deci’s (1975) theory of intrinsic motivation and the need for more research examining attribute–treatment interactions with respect to training and skill acquisition. 相似文献

Little work has studied achievement goals in social interaction situations. The present experiment aimed at contributing to
this matter by showing the potential of social interaction (in particular disagreement) to moderate the effects of achievement
goals on learning. Participants were led to think they interacted with a partner, sharing opinions about a text that they
were studying. Mastery and performance goals were manipulated. During the “interaction,” they received either disagreement
or agreement from this bogus partner. Results showed that a condition in which mastery goals were induced led to better learning
than a performance goal condition only when the partner disagreed. No differences between goal conditions were observed when
the partner agreed. Implications for achievement goal research are discussed.

Mental fatigue influence on effort-related cardiovascular response: difficulty effects and extension across cognitive performance domains 总被引:2,自引:0,他引:2

Two experiments investigated cardiovascular effects of mental fatigue as a function of (1) the difficulty of the cognitive
challenge with which participants were confronted, and (2) the relevance of that challenge to the activity that instigated
the fatigue. In the first, participants performed an easy (fatigue low) or difficult (fatigue high) counting task and then
were presented an arithmetic challenge (task B relevance high) or a scanning challenge (task B relevance low) with instructions
that they would avoid a noise if they attained a modest performance standard. Analysis of blood pressure responses assessed
during the work periods revealed fatigue main effects, reflecting stronger responses for High Fatigue participants, regardless
of the character of the second task. In the second, the procedure was the same except that it included a high performance
standard and provided the chance to win a prize. Analysis of the pressure data revealed fatigue x work period interactions,
reflecting relatively stronger responses among High Fatigue participants in work period 1, but relatively weaker responses
among these participants in work period 2. Results confirm previous findings and support an analysis of fatigue influence
on effort and associated cardiovascular responses. They also argue against the idea that mental fatigue influence may be confined
to relevant cognitive performance realms.

Federally funded out‐of‐school time (OST) programs provide academic support, enrichment, and safety for students and families in low‐resource communities. However, programs struggle to meet these aims, in part because of the lack of program structure and limited training and support for staff. This observational case study documents the training and technical assistance (TA) delivered to OST frontline staff and program leadership to implement Positive Behavior in Out‐of‐School Time (Positive BOOST), an adaptation of positive behavior interventions and supports conducted in multiple settings. Findings across three programs indicate that varied levels of TA (i.e., business as usual, performance feedback, coaching) are associated with different levels of staff‐ and program‐level implementation. Taken together with previous research, these findings suggest that targeted investment in developing the skills of OST staff and improving program‐wide outcomes is critical for supporting youth in low‐resource communities. 相似文献

This study aimed to assess the stability of the performance, pace and turn parameters of elite long-distance male swimmers during an 800 m freestyle race. The sample was composed by 38 male swimmers, participating in the 800 m event at the 2016 LEN European Aquatic Championships (long course meter). The performance, and a set of pace and turn parameters were analyzed. A customized software was used to perform each race analysis. Swimmers spent 64.05 ± 0.50% and 35.95 ± 0.49% of the final race time in the clean swim and turns, respectively. In the pace parameters, the clean swim was the only one that did not differ between the first and second half of the race (1.63 ± 0.05 vs 1.62 ± 0.05 m·s−1), and in the turn parameters, the water break distance was also similar (5.13 ± 1.17 vs 5.06 ± 0.98 m). A significant and moderate-strong variation was verified for the performance (total race lap effect: p < 0.001, η2 = 0.62), and a significant and moderate variation for the pace parameters (total race: p < 0.001, 0.15 ≤ η2 ≤ 0.33), and for the turn parameters (total race: p < 0.01, 0.15 ≤ η2 ≤ 0.33). Present data (pace and turn variation) shows that elite long-distance male swimmers do not maintain a similar pattern during an 800 m freestyle race. Future research is need to understand if this lack of pace and turn stability is the best way to enhance the performance, or if swimmers should be advised to control their pace and turn. Nevertheless, coaches are advised to help swimmers with feedback about their pace (i.e., controlling the intermediate 30 m) and turn performances (i.e., controlling the 5 m in and 15 m out), leading to a positive effect in their final race time. 相似文献

Transcranial Direct Current Stimulation (tDCS) is a neuromodulatory technique that has been used as an ergogenic aid in exercise/sports performance. However, little is known about its effects on highly-trained subjects, as athletes. The present study aimed to verify the effects of bi-hemispheric anodal tDCS (a-tDCS) on the performance of taekwondo athletes. Additionally, we investigated the persistence of the effects of the a-tDCS one hour after it. Nineteen Taekwondo athletes received active or sham bi-hemispheric a-tDCS over the primary motor cortex (M1). a-tDCS was delivered at 1.5 mA for 15 min. Athletes performed Countermovement Jumps (CMJ) and the Frequency Speed of Kick Test (FSKT) immediately (Mo1) and one hour after stimulation (Mo2). The athletes also reported their session-rating of perceived exertion (session-RPE). The total number of kicks (TK) was higher in sham than in the active a-tDCS condition (p < 0.01). In addition, TK was higher at Mo2 than at Mo1 (p < 0.05). Similarly, the session-RPE was higher in the a-tDCS condition (p < 0.05) and was greater one-hour post-stimulation (p < 0.01). No differences were found for CMJ performance (p > 0.05). Thus, bi-hemispheric a-tDCS worsens performance of taekwondo athletes, and the effect remains present even 1 h after the stimulation. 相似文献

The purpose of this study was to explore the level of inter- and intra-individual variability in the kinematic profiles of the back squat movement among skilled weightlifters. Ten competitive weightlifters volunteered for participation in this study. Barbell velocity (VBarbell) and angular velocity of the ankle (ωAnkle), knee (ωKnee) and hip joint (ωHip) were obtained by kinematic recording of six trials at 90% of 1RM in the back squat. Inter-individual variability was assessed by analysing inter-individual differences in the velocity curves through the statistical parametric mapping method. Intra-individual variability was assessed through a correlation analysis between the barbell velocity curves of each trial for each participant. Partial least squares regression analysis, was performed to relate changes in intra-individual variability to movement and anthropometric characteristics. Significant inter- and intra-individual differences were identified in VBarbell, ωAnkle, ωKnee, and ωHip (p ≤ 0.05). Having a short trunk and thigh, and a long shin in combination with greater anterior-posterior displacement of the barbell and slower velocities during the acceleration phase increased intra-individual movement consistency over movement variability. The results of the present study clearly demonstrate that skilled weightlifters display both significant inter- and intra-individual variability in the successful execution of the back squat. 相似文献

Feelings and cognitions influence judgment through attribution. For instance, the attribution of positive feelings and cognitions to a stimulus leads to a positive judgment of that stimulus. We examined whether misattribution is moderated by the applicability of a distractor to the judgment question. For instance, when are people more likely to attribute to a target person the affective and cognitive experiences triggered by a kitten – when trying to judge the person’s cuteness or trustworthiness? The kitten triggers experiences specifically relevant to cuteness, but people might more easily suspect the kitten’s potential influence when judging cuteness rather than trustworthiness. Using the Affect Misattribution Procedure, we found that applicability increases the effect of misattribution on valenced judgments. The results emphasise the importance of specific information (rather than only general valence) in attribution and suggest that high applicability of distractors to the judgment question does not elicit effective correction. 相似文献

This paper examines the moderating role of goal orientations (learning, performance and avoidance orientation) in the relationship between job scope (i.e., a composite measure capturing task variety, autonomy, feedback and significance) and organizational commitment. Based on a sample of 314 participants, the analyses indicate that job scope is positively related to commitment and that performance orientation and avoidance orientation act as negative moderators of job scope. Specifically, job scope was more strongly related to commitment at low levels of these traits. We discuss the importance of considering the role of employee personality in the study of the effect of work context on commitment. 相似文献

To formalize the human judgment of rhythm complexity, we used five measures from information theory and algorithmic complexity to measure the complexity of 48 artificially generated rhythmic sequences. We compared these measurements to human prediction accuracy and easiness judgments obtained from a listening experiment, in which 32 participants guessed the last beat of each sequence. We also investigated the modulating effects of musical expertise and general pattern identification ability. Entropy rate and Kolmogorov complexity were correlated with prediction accuracy, and highly correlated with easiness judgments. A logistic regression showed main effects of musical training, entropy rate, and Kolmogorov complexity, and an interaction between musical training and both entropy rate and Kolmogorov complexity. These results indicate that information‐theoretic concepts capture some salient features of the human judgment of rhythm complexity, and they confirm the influence of musical expertise on complexity judgments. 相似文献
