Building upon Deci's and Ryan (1985) Self-determination theory as well as the sportive behavioral correlates of the model of Commitment (Scanlan et al., 1976), this study tries to establish the relationship between motivation and commitment in youth sport. For this purpose 454 young competitive soccer players answered the Sport Motivation Scale (SMS) and the Sport Commitment Questionnaire (SCQ) during the regular season. The SMS measures the three dimensions of the Motivational continuum (the Amotivation, the Extrinsic Motivation and the Intrinsic Motivation). The SCQ measures the Sportive Commitment and its composing factors such as the Enjoyment, the Alternatives to the sport, and the Social Pressure. Our findings provided a clear pattern of the influence of motivation in sport enjoyment and commitment, outlining the positive contribution of intrinsic and extrinsic motivation to enjoyment and commitment. Amotivation, contributes positively to alternatives to sport and negatively to enjoyment and commitment, It should be noted that extrinsic motivation has a higher contribution to enjoyment whereas intrinsic motivation has a higher contribution to commitment.  相似文献

In this paper I take up Dana Amir's concept of the “chameleon language” of perversion considering Wittgenstein's idea of the language-game and the necessity of taking up the context of communication. The setting of psychoanalysis represents a new context for the language of perversion, one that at first implicitly and later explicitly recognizes the bid for tenderness beneath the stealth. I suggest it is the analyst's willingness to risk vulnerability in this game, as much as the interpretation of perverse pacts, that fosters clinical change.  相似文献

We developed and evaluated a brief (8-session) version of cognitive-behavioral therapy (BCBT) for anxiety disorders in youth ages 6 to 13. This report describes the design and development of the BCBT program and intervention materials (therapist treatment manual and child treatment workbook) and an initial evaluation of child treatment outcomes. Twenty-six children who met diagnostic criteria for a principal anxiety diagnosis of separation anxiety disorder, generalized anxiety disorder, and/or social phobia were enrolled. Results suggest that BCBT is a feasible, acceptable, and beneficial treatment for anxious youth. Future research is needed to examine the relative efficacy of BCBT and CBT for child anxiety in a randomized controlled trial.  相似文献

We report lexical decision experiments in which eye movements and lexical decision time were analysed. The results show that nonwords produced more fixation than words, and that the time to make a lexical decision was also greater for nonwords. Further, a preview of the stimulus was presented on some occasions either at fixation or peripherally. When the presentation was peripheral the number of refixations and lexical decision times were reduced. Parafoveal previews of words also reduced word length effects on refixations and lexical decision time. These effects decreased (for nonwords) when the case of the letters was changed in the preview. These results are compatible with the idea that the peripheral preview benefit derives from word visual structure in addition to information about word length, word envelope, and single letter identities.  相似文献

In this study, we investigated the level of visual processing at which surface colour information improves the naming of colour diagnostic and noncolour diagnostic objects. Continuous electroencephalograms were recorded while participants performed a visual object naming task in which coloured and black-and-white versions of both types of objects were presented. The black-and-white and the colour presentations were compared in two groups of event-related potentials (ERPs): (1) The P1 and N1 components, indexing early visual processing; and (2) the N300 and N400 components, which index late visual processing. A colour effect was observed in the P1 and N1 components, for both colour and noncolour diagnostic objects. In addition, for colour diagnostic objects, a colour effect was observed in the N400 component. These results suggest that colour information is important for the naming of colour and noncolour diagnostic objects at different levels of visual processing. It thus appears that the visual system uses colour information, during naming of both object types, at early visual stages; however, for the colour diagnostic objects naming, colour information is also recruited during the late visual processing stages.  相似文献

The aim of this study was to analyze the possible relationship between circulating hormone levels (testosterone, androstenedione and estradiol) and empathy, as well as to identify any possible gender differences in this relationship. The subjects were 123 9-year-old Caucasian children (57 boys and 66 girls). Bryant’s Empathy Index was used to measure empathy. Hormone levels were measured using an enzyme immunoassay technique in saliva samples. The Kruskal–Wallis test revealed the existence of interaction effects of estradiol-gender and testosterone-gender on empathy. Girls with low testosterone levels scored higher in Cognitive Empathy than girls with high testosterone levels. Boys with low estradiol levels scored higher in Affective Empathy than boys with high levels of this hormone. The results obtained open up new and interesting avenues of future research into the relationship between hormones and empathy in children.  相似文献

As the Latino population in the United States continues to increase, so does the necessity for in-depth knowledge about their life experiences. This qualitative study sought to privilege the voices of Latino parents by utilizing focus group discussions. Specifically, participants described the life experiences that have the greatest influence on their parenting efforts. Similar and contrasting themes were identified based on participant country of origin (i.e., foreign born vs. U.S. born). Findings described the participants' commitment to being good parents, as well as the ways in which their parenting efforts are influenced by experiences of adversity and discrimination, Latino cultural values, gender roles, and resilience. The results of this investigation can inform researchers and mental health professionals working with Latino families.  相似文献

Individual morningness-eveningness differences explain the rhythmic variations of behavioral and biological patterns. Several studies have corroborated that morningness preference increases over adulthood and aging. Adolescents shift their time of day preferences from morningness to eveningness during puberty. The aims of this study were translate to Spanish the Morningness-Eveningness Scale for Children (MESC) and to analyze age and sex differences. A group of 600 adolescents (aged between 12 and 16 years) participated in the study. Psychometric analysis showed that reliability and factor structure were suitable and similar to previous studies. The results indicated a clear decrease of morningness as of 12 years. Boys were more morningness-oriented than girls in several items of the questionnaire. In view of the results, several educational implications are raised.  相似文献

If examinees were to know, beforehand, part of the content of a computerized adaptive test, their estimated trait levels would then have a marked positive bias. One of the strategies to avoid this consists of dividing a large item bank into several sub-banks and rotating the sub-bank employed (Ariel, Veldkamp & van der Linden, 2004). This strategy permits substantial improvements in exposure control at little cost to measurement accuracy, However, we do not know whether this option provides better results than using the master bank with greater restriction in the maximum exposure rates (Sympson & Hetter, 1985). In order to investigate this issue, we worked with several simulated banks of 2100 items, comparing them, for RMSE and overlap rate, with the same banks divided in two, three... up to seven sub-banks. By means of extensive manipulation of the maximum exposure rate in each bank, we found that the option of rotating banks slightly outperformed the option of restricting maximum exposure rate of the master bank by means of the Sympson-Hetter method.  相似文献
