The purpose of this study was to investigate the differences of knee concentric and eccentric strength and impact related knee biomechanics between jumpers and non-jumpers during step-off landing tasks. Ten male college swimming athletes (non-jumpers) and 10 track and volleyball athletes (jumpers) were recruited to participate in two test sessions: a muscle strength testing session of concentric and eccentric extension for dominant knee joint at 60 °/s and 180 °/s and a landing testing session. The participants performed five trials of step-off landing in each of four conditions: soft and stiff landing from 0.4 m and 0.6 m landing heights. The three-dimensional kinematics and ground reaction force were recorded simultaneously during step-off landing conditions. The results showed that the jumpers had significantly greater peak knee eccentric extension and concentric flexion torques compared to the non-jumpers. No significant group effects were found for peak vertical ground reaction force and knee range of motion during landing. The jumpers had significantly greater knee contact flexion angle, maximum knee flexion angle and initial knee extension moment compared to the non-jumpers. These results suggest that these athletes adopted a favorable impact attenuation strategy that is related to the greater knee eccentric muscle strength and training. 相似文献

The current study aimed to analyze the importance of trait emotional intelligence in life satisfaction and to extend the previous literature by investigating the potential mediating effects of resilience and affect balance in this relationship. To test the study hypotheses, self-report measures of trait emotional intelligence, resilience, positive and negative affect, and life satisfaction were administrated to 263 undergraduates. Correlation analysis indicated that trait emotional intelligence was positively correlated with life satisfaction. Mediational analyses showed that trait emotional intelligence exerted its indirect effect on life satisfaction through the simple mediating effect of affect balance and the three-path mediating effect of resilience–affect balance. In addition, resilience played as a partial mediator between trait emotional intelligence and affect balance. Furthermore, multi-group analyses showed that the mediational model was not moderated by gender. Therefore, this study makes a contribution to the complex nature of the association between trait emotional intelligence and subjective well-being. 相似文献

The study examined the prevalence of five types of childhood trauma in a sample of adult clients (n = 497) as well as their long-term relation to trauma symptoms in adulthood. Results showed a high prevalence of abuse and neglect with emotional abuse and neglect being the most common ones. Emotional abuse was the best and strongest predictor of trauma symptoms in adulthood, including anxiety, depression, defensive avoidance, as well as internal confusion and emptiness. The results indicated that experience of emotional abuse is no less significant than that of physical and sexual abuse in its long-term impact. Clinical implication was provided. 相似文献

This study examined whether adult attachment was predictive of conflict resolution behaviors and satisfaction in romantic relationships. It adopted a two-dimensional conceptualization for both adult attachment style (model of self, model of others) and conflict resolution behaviors (concern for self, concern for others). Both adult attachment dimensions, Avoidance and Anxiety, were predictive of conflict resolution behaviors and relationship satisfaction. Gender differences existed in conflict resolution behaviors, but they were not as strong a predictor as attachment characteristics of conflict resolution and relationship satisfaction. No gender differences were found in attachment styles. 相似文献

Gambling near‐misses are non‐rewarded events that resemble a winning configuration. Past research using slot machines has shown that moderate rates of near‐misses increase gambling persistence, but the mechanisms supporting this persistence are unclear. One hypothesis is that near‐misses are mistakenly interpreted as signals of skill acquisition, supporting learning and fuelling the ‘illusion of control’. A slot machine simulation was administered to 60 volunteers, with ratings of the perceived chances of winning, pleasure and motivation to play following particular outcomes. Psychophysiological measures (electrodermal activity and heart rate) were taken, and gambling persistence was measured after 30 trials. Near‐misses were similar to full‐miss outcomes in that they were regarded as unpleasant. However, near‐misses were akin to win outcomes in that they increased motivations to play and electrodermal activity. Learning was evidenced by the expectancy of winning increasing following wins and decreasing after losses. Although there was no overall change in expectancy of winning after near‐misses across all participants, those subjects reporting a greater increase in the expectancy of winning following a near‐miss showed more persistent play, consistent with the learning hypothesis. Greater heart rate acceleration following near‐misses was also associated with persistence. We also observed differential effects of near‐misses where the reel stopped either side of the winning position (‘payline’): motivational effects were restricted to near‐misses stopping before the payline, whereas near‐misses that stopped after the payline were primarily aversive. The payline effects are not predicted by the learning hypothesis and may indicate an affective component to near‐misses, possibly linked to counterfactual processing.

This study investigated the sensitivity of common fit indices (i.e., RMSEA, CFI, TLI, SRMR-W, and SRMR-B) for detecting misspecified multilevel SEMs. The design factors for the Monte Carlo study were numbers of groups in between-group models (100, 150, and 300), group size (10, 20, 30, and 60), intra-class correlation (low, medium, and high), and the types of model misspecification (Simple and Complex). The simulation results showed that CFI, TLI, and RMSEA could only identify the misspecification in the within-group model. Additionally, CFI, TLI, and RMSEA were more sensitive to misspecification in pattern coefficients while SRMR-W was more sensitive to misspecification in factor covariance. Moreover, TLI outperformed both CFI and RMSEA in terms of the hit rates of detecting the within-group misspecification in factor covariance. On the other hand, SRMR-B was the only fit index sensitive to misspecification in the between-group model and more sensitive to misspecification in factor covariance than misspecification in pattern coefficients. Finally, we found that the influence of ICC on the performance of targeted fit indices was trivial. 相似文献

The present study aims to explore the influence of emotional context on word evaluation. Participants were asked to read an “adjective + noun” phrase, where the adjective could be a positive or negative word, and the noun could be a positive, neutral or negative word, and then to make an emotional evaluation on the emotional tone of the target noun based on a 9-point Likert scale. In a control condition, an isolated noun was presented with no context. Results showed that positive context made the evaluation of target words bias toward positive tone, while negative context shaped the evaluation of target words toward negative tone. The modulatory effect of negative context was greater than that of positive context in shaping evaluation of emotional words with opposite valence. Moreover, the modulatory effect of emotional context was constrained by the inherent meaning of target word. The present study demonstrated the flexibility as well as the relative stability of emotional meaning of word. 相似文献

This study examined associations of peer socialization and selection, over time, with nonsuicidal self-injury (NSSI) among 5,787 (54.2 % females) Chinese community adolescents. Both effects were tested using two aspects of adolescents’ friendship networks: the best friend and the friendship group. Participants completed questionnaires assessing NSSI, depressive symptoms and maladaptive impulsive behaviors at two waves of time over a 6-month period. Results showed that even after controlling for the effects of depressive symptoms and maladaptive impulsive behaviors, the best friends’ engagement in NSSI still significantly predicted adolescents’ own engagement in NSSI. Adolescents’ friendship groups’ NSSI status also significantly predicted their own NSSI status and frequency. Additionally, adolescents with NSSI tended to join peer groups with other members also engaging in NSSI. 相似文献

The present study promulgates a research stream in the area of understanding women's position in the management of the Chinese sales force. The study investigates attitudes toward women as sales managers held by Chinese salespeople. Male salespeople consistently rated the female sales managers lower than did female salespeople on three sets of attitude items. This finding indicates the presence of male resistance to women in sales management positions. 相似文献
