A single-subject design was used to examine the influence of one session of neurofeedback training (NFT) on reducing frontal midline theta (Fmθ) amplitude and enhancing golf putting performance. Posttraining, three highly skilled golfers improved in putting score or score stability. Although the Fmθ amplitude during the pre-putt period inconsistently decreased across participants, all golfers exhibited lower Fmθ amplitude during the resting condition following NFT, suggesting that the tonic reduction of Fmθ may play a role in subsequent performance improvement. Overall, these results indicate that a short session of NFT may be an effective method of performance enhancement in some sports.  相似文献

The present experiment investigated the hypothesis that a weapon can serve as a cue that will interfere with the eyewitness’ encoding of the weapon-holder's facial features. Extrapolating from Easterbrook's cue utilization hypothesis, an interaction between arousal and attentional focus was predicted. White female college students played a bogus visual discrimination game in which they saw a total of 24 target photos: six black targets holding a weapon in their hands, six white targets holding weapons, six black targets holding objects other than weapons, and six white targets holding objects other than weapons. Subjects were randomly assigned to view the photos while experiencing white noise and threat of electric shock (high arousal) or without such factors (low arousal). Subjects were also randomly assigned to one of four attentional focus levels: face focus, hand focus, background focus, and free focus. A signal detection-type task provided an assessment of identification accuracy. The data revealed a significant “weapon effect”: Subjects were better at identifying photos of targets who were not holding a weapon than they were at identifying photos of targets who were holding a weapon. Focus of attention and race of target also significantly affected recognition accuracy, as did arousal in one of two analyses. No support was found, however, for the predicted interaction between arousal and attentional focus. Finally, subjects showed a strong criterion shift according to the race of target; they were much more likely to make a “seen before” response to other-race (black) faces than to same-race faces.  相似文献

Wulf and colleagues (e.g., Wulf, Lauterbach, & Toole, 1999 Wulf, G., Lauterbach, B. and Toole, T. 1999. The learning advantages of an external focus of attention in golf. Research Quarterly for Exercise and Sport, 70: 1219126.  [Google Scholar]) have demonstrated that the adoption of an external focus of attention is preferable for the learning of complex motor tasks. The present investigation extends the attention focus literature in two ways: (a) it compared the effectiveness of three different foci (internal, proximal external, and distal external) in a sample of skilled performers in a naturalistic environment, and (b) it examined the use of attentional foci under conditions of anxiety. Thirty-three skilled male golfers were assigned to one of three attentional focus groups and completed five blocks of ten pitch shots, three in neutral conditions and two in anxiety conditions. Results from two separate mixed model analyses of variance (ANOVAs) indicated that regardless of anxiety condition, those assigned to a distal external focus of attention performed most accurately (p < 0.05), whereas assignment to an internal focus of attention was associated with the least accurate performance (p < 0.05). Findings offer support for the constrained action hypothesis and point to the importance of skilled performers adopting a distal external focus, especially in competition.  相似文献

Three experiments investigate the effect of a parent's attentional focus on the pointing of children from 1 to 2 years of age. Children were presented with an interesting sight on one or the other side of a laboratory room while the parent was either looking toward that side or not. The results show that 1-year-olds are more likely to point when the parent is looking at them, whether or not the parent has already seen the interesting sight. In contrast, 2-year-olds tend to point more both when the partner has not seen and when she is no longer looking at the sight than when she is looking at it. These findings are consistent with the idea that when they first start to point, infants use the gesture to enhance the interaction rather than to redirect the attention of the partner. By 2 years of age, children point to redirect attention to an interesting sight and to share attention with a communicative partner.  相似文献

The Attentional Focus Model (Karau & Kelly, 1992) predicts that time pressure should lead group members to focus on a restricted range of task-relevant cues and to adopt task completion as their major interaction objective. Although this prediction has been supported in several studies (e.g., Karau & Kelly, 1992; Kelly, Jackson, & Hutson-Comeaux, 1997; Kelly & Karau, 1999; Parks & Cowlin, 1995), the exact processes that underlie information restriction have not been specified. We propose that two processes are involved. Specifically, the restriction of information may occur because time pressure affects the way in which information is initially encoded or attended to before a group enters its decision-making phase, or because group members filter out what they judge to be less important information during group discussion and decision making. We assessed both of these processes within a decision-making experiment where time pressure was manipulated prior to learning information that would be used to perform a task. Recall of information learned prior to group discussion did not differ by time pressure condition, arguing against an encoding process. In contrast, interaction data demonstrated information restriction by group members, arguing for a filtering process. Thought listings collected 1 min into the group discussion in some groups also supported a filtering process, as did questionnaire data. Implications of these findings for the Attentional Focus Model and for effective group decision making are discussed.  相似文献

ABSTRACT Dieting and nondieting subjects were given either failure or neutral performance feedback on a problem-solving task. Failure subjects were then assigned to one of three self-awareness conditions: One group was forced to watch a video clip of themselves failing on the problem-solving task, one group was asked to watch a distracting video clip on bighorn sheep, and the final group was asked to sit quietly for 10 minutes. Subjects were then allowed to eat as much ice cream as they wanted. Only in those conditions which allowed—or promoted—low self-awareness (the failure/distraction and simple failure condition) did dieters show disinhibited eating. In the failure/videotape condition, which enforced high levels of self-awareness, eating in dieters remained inhibited. This supports the proposal that a reduction in self-awareness is necessary for lifting of inhibitions. Eating in nondieters was reduced in the failure/videotape and simple failure conditions, possibly because of the autonomic correlates of distress.  相似文献

To examine the effect of positive rumination training on mental health and attentional bias, 32 college freshmen with low level of mental health were recruited and assigned to the experimental and waitlist control groups, 16 participants in each group. The experimental group received a 8-session group counseling with 2 h per session. Results showed that positive rumination increased while negative rumination, depression and anxiety decreased significantly for the experimental group. For the waitlist control group, all these indicators did not change significantly. The attention engagement in sad faces of the experimental group decreased significantly while other indicators of attentional bias did not change. The results indicate that group positive rumination training can improve mental health. But further research is needed to examine its effect on attentional bias.

Theories of motor learning predict that training a movement reduces the amount of attention needed for its performance (i.e., more automatic). If training one movement transfers, then the amount of attention needed for performing a second movement should also be reduced, as measured under dual task conditions. The authors’ purpose was to test whether dual task paradigms are feasible for detecting transfer of training between two naturalistic movements. Immediately following motor training, subjects improved performance of a second untrained movement under single and dual task conditions. Subjects with no training did not. Improved performance in the untrained movement was likely due to transfer, and suggests that dual tasks may be feasible for detecting transfer between naturalistic actions.  相似文献

Outdoor behavior was measured and compared using a behavioral mapping procedure across three contrasting environments in a low-income urban neighborhood. The environments were an old ghetto neighborhood of low-rise tenement houses, a traditional high-rise housing project, and an innovative high-rise housing project, where a creative outdoor design had been added to encourage outdoor use. As predicted, the old neighborhood and the innovative project showed higher levels of outdoor socializing than did the traditional project. Unexpectedly, the old neighborhood showed the highest level of task-oriented activity relative to recreation and leisure. Several propositions concerning the relationship between behavior and urban environment are considered, and a number of implications for urban design are advanced.  相似文献

ABSTRACT Psychological research on morality has been based on researchers' definitions of morality or on philosophical theories. The present study examined naturally occurring conceptions of morality by using a knowledge-structure methodology borrowed from cognitive psychology. Subjects generated statements in response to a question designed to expose generic knowledge about their concept of morality. Answer frequency and conceptual clustering results suggested that a variety of diverse concepts undergirded subjects' moral thinking and revealed a person-based rather than a philosophy-based pattern for commonly held conceptions of morality. A three-dimensional scaling solution of the responses suggested that conceptions of morality were characterized by individual-social, general-specific, and absolute-relative distinctions. These findings raise questions about assumptions underlying previous theories of morality. Moreover, the present methodology offers a basis for developing a more representative account of moral thought that depends less on the beliefs of researchers.  相似文献

In this study, we explored the ability of first league professional volleyball players to modulate the allocation of attentional resources in the visual space by adapting the size of the attentional focus. Like Castiello and Umilta (1990), we employed an experimental procedure that is a variation of Posner's (1980) paradigm for exploring covert orienting of visuospatial attention. In a signalled reaction time task, a peripheral cue of varying size was presented unilaterally or bilaterally of a central fixation point, followed by a target at different stimulus onset asynchronies. The target could occur validly inside the cue or invalidly outside it with varying spatial relation to its boundary. Our results suggest that volleyball players are better able than controls to modulate the distribution of attentional resources within and around peripherally cued areas. Moreover, volleyball players seem to be able to flexibly adapt the gradient of attentional resources around the cued area, as would be expected from their sport practice.  相似文献

The effectiveness of an 8-week mindfulness training for adolescents aged 11–15?years with ADHD and parallel Mindful Parenting training for their parents was evaluated, using questionnaires as well as computerized attention tests. Adolescents (N?=?10), their parents (N?=?19) and tutors (N?=?7) completed measurements before, immediately after, 8?weeks after and 16?weeks after training. Adolescents reported on their attention and behavioral problems and mindful awareness, and were administered two computerized sustained attention tasks. Parents as well as tutors reported on adolescents’ attention and behavioral problems and executive functioning. Parents further reported on their own parenting, parenting stress and mindful awareness. Both the mindfulness training for the adolescents and their parents was delivered in group format. First, after mindfulness training, adolescents’ attention and behavior problems reduced, while their executive functioning improved, as indicated by self-report measures as well as by father and teacher report. Second, improvements in adolescent’ actual performance on attention tests were found after mindfulness training. Moreover, fathers, but not mothers, reported reduced parenting stress. Mothers reported reduced overreactive parenting, whereas fathers reported an increase. No effect on mindful awareness of adolescents or parents was found. Effects of mindfulness training became stronger at 8-week follow-up, but waned at 16-week follow-up. Our study adds to the emerging body of evidence indicating that mindfulness training for adolescents with ADHD (and their parents) is an effective approach, but maintenance strategies need to be developed in order for this approach to be effective in the longer term.  相似文献

Therapists and supervisors engaged in the delivery of home-based services participated in two rounds of focus groups. Participants discussed the challenges they face doing home-based therapy, and how an accredited family therapy program could modify its curriculum to better prepare trainees to meet these demands. Eight topic areas considered necessary for home-based practice were identified and the implications for training reviewed. The focus group methodology is described in detail and is recommended as a useful tool to assess training needs and as a way of promoting improved collaboration among training sites.  相似文献

In recent years there has been growing interest in determining the attentional basis of positive affectivity. Investigators have sought to evaluate the hypothesis that elevated positive affectivity is characterized by an attentional bias that favours the processing of positive information over neutral information. Unfortunately, in the studies carried out to date, the assessment procedures used by researchers to assess such attentional selectivity have either been methodologically limited or methodologically flawed. Hence, the validity of the hypothesis has remained indeterminate. To overcome the problems associated with attentional assessment procedures used in previous studies, and so shed light on the attentional basis of positive affectivity, we employed an appropriate variant of the attentional probe task. Our findings show that participants high in positive affectivity displayed greater relative attention to positive information compared to neutral information, than was the case for their low positive affectivity counterparts. Thus, the present results support the hypothesis that an attentional bias to positive information, relative to neutral information, is characteristic of elevated positive affectivity.  相似文献

A two-week training programme was provided to male and female trainees. Data were collected on each of the subject's locus of control and on each subject's perception of the degree to which their work environment would be supportive of application of skills acquired in training. The outcome variables measured for the 73 trainees (35 males, 38 females) included motivation to transfer, evaluation of the training programme, the grade achieved at the conclusion of training, self-report and immediate superior's evaluation of the use of acquired skills. Data were also collected on seniority. Hierarchical regression analysis was employed to test the effect of gender, and training-related variables on training outcomes. Controlling for the effect of seniority the data indicated that gender had an impact on motivation to transfer, and gender and seniority both had a significant effect on reaction to the course. Perceived work environment support and its interaction with seniority also accounted for a significant portion of explained variance of motivation to transfer and reactions to the course. Locus of control did not have a significant effect on four of the training outcomes but the interaction of locus of control and seniority affected the superior's evaluation of the use of skills. The results are discussed in terms of their tactical and strategic implications for the relationship between training-related variables and gender.  相似文献
