Previous research has shown that high socially anxious individuals lack the benign interpretation bias present in people without social anxiety. The tendency of high socially anxious people to generate more negative interpretations may lead to anticipated anxiety about future social situations. If so, developing a more benign interpretation bias could lead to a reduction in this anxiety. The current study showed that a benign interpretation bias could be facilitated (or 'trained') in a high socially anxious population. Participants in the benign training groups had repeated practice in accessing benign (positive or non-negative) interpretations of potentially threatening social scenarios. Participants in the control condition were presented with the same social scenarios but without their outcomes being specified. In a later recognition task, participants who received benign interpretation training generated more benign, and less negative, interpretations of new ambiguous social situations compared to the control group. Participants who received benign training also predicted that they would be significantly less anxious in a future social situation than those in the control group. Possible implications of the findings for therapeutic interventions in social phobia are discussed. 相似文献

While the scientist–practitioner model of training has enjoyed wide-spread appeal, difficulties in implementing the model
have continued since its inception. Despite these difficulties, we remain advocates of the model and believe responsibility
for inculcating a scientist–practitioner mindset rests with both training programs and trainees themselves. Thus, we offer
several suggestions for both trainees and training programs in hopes of perpetuating the scientist–practitioner ideal. 相似文献

Recent research reveals a link between individual differences in mathematics achievement and performance on tasks that activate the approximate number system (ANS): a primitive cognitive system shared by diverse animal species and by humans of all ages. Here we used a brief experimental paradigm to test one causal hypothesis suggested by this relationship: activation of the ANS may enhance children’s performance of symbolic arithmetic. Over 2 experiments, children who briefly practiced tasks that engaged primitive approximate numerical quantities performed better on subsequent exact, symbolic arithmetic problems than did children given other tasks involving comparison and manipulation of non-numerical magnitudes (brightness and length). The practice effect appeared specific to mathematics, as no differences between groups were observed on a comparable sentence completion task. These results move beyond correlational research and provide evidence that the exercise of non-symbolic numerical processes can enhance children’s performance of symbolic mathematics. 相似文献

In the initial interviews of family therapy sessions, the therapist faces the challenge of obtaining and organizing the information that is most relevant toward understanding the essential concerns that families and couples bring to therapy. This article describes the process of clinical interviewing and case conceptualization used in training family therapists at the Ackerman Institute for the Family. This approach helps the therapist bring forward, and organize, specific information into relational hypotheses, or systemic‐relational conceptualizations, that allow both family members and the therapist to understand presenting problems within their relational contexts. While always provisional, relational hypotheses help anchor the therapist in a systemic‐relational frame and provide a conceptual through‐line to guide the ongoing work of the therapy. The process of interviewing and the construction of clear and complex conceptualizations of presenting problems are illustrated through case examples. 相似文献

We examine, in 6881 twin individuals, the psychometric properties of a new test (the Swedish Musical Discrimination Test, SMDT) that was developed to tap auditory discrimination of musical stimuli. The SMDT consists of three subtests measuring discrimination of melodies, rhythms, and single pitches, respectively. Mean test taking times for the subtests were 3.0–4.6 min. Reliability and internal consistency were good with Cronbach’s alpha values and Spearman–Brown split-half reliabilities between .79 and .89. Subtests correlated positively (r values .27–.41). Criterion validity was demonstrated in three ways: individuals that had played a musical instrument scored higher than individuals that had not (Cohen’s d .38–.63); individuals that had taken music lessons scored higher than individuals that had not (Cohen’s d .35–.60); finally, total hours of musical training and SMDT scores correlated (r values .14–.28) among those participants that had played an instrument. Lastly, twin modelling revealed moderate heritability estimates for the three sub-scales. We conclude that the SMDT has good psychometric characteristics, short test taking time, and may serve as a useful complement to existing tests of musical ability. 相似文献

Previous studies on working memory training have indicated that transfer to non-trained tasks of other cognitive domains may be possible. The aim of this study is to compare working memory training and transfer effects between younger and older adults (n = 60). A novel approach to adaptive n-back training (12 sessions) was implemented by varying the working memory load and the presentation speed. All participants completed a neuropsychological battery of tests before and after the training. On average, younger training participants achieved difficulty level 12 after training, while older training participants only reached difficulty level 5. In younger participants, transfer to Verbal Fluency and Digit Symbol Substitution test was found. In older participants, we observed a transfer to Digit Span Forward, CERAD Delayed Recall, and Digit Symbol Substitution test. Results suggest that working memory training may be a beneficial intervention for maintaining and improving cognitive functioning in old age. 相似文献

This study aimed at quantifying upper limb kinetic asymmetries in maximal front crawl swimming and to examine if these asymmetries would affect the contribution of force exertion to swimming performance. Eighteen high level male swimmers with unilateral breathing patterns and sprint or middle distance specialists, volunteered as participants. A load-cell was used to quantify the forces exerted in water by completing a 30 s maximal front crawl tethered swimming test and a maximal 50 m free swimming was considered as a performance criterion. Individual force–time curves were obtained to calculate the mean and maximum forces per cycle, for each upper limb. Following, symmetry index was estimated and breathing laterality identified by questionnaire. Lastly, the pattern of asymmetries along the test was estimated for each upper limb using linear regression of peak forces per cycle. Asymmetrical force exertion was observed in the majority of the swimmers (66.7%), with a total correspondence of breathing laterality opposite to the side of the force asymmetry. Forces exerted by the dominant upper limb presented a higher decrease than from the non-dominant. Very strong associations were found between exerted forces and swimming performance, when controlling the isolated effect of symmetry index. Results point that force asymmetries occur in the majority of the swimmers, and that these asymmetries are most evident in the first cycles of a maximum bout. Symmetry index stood up as an influencing factor on the contribution of tethered forces over swimming performance. Thus, to some extent, a certain degree of asymmetry is not critical for short swimming performance. 相似文献

Allowing learners to control the video presentation of knowledge of performance (KP) or an expert model during practice has been shown to facilitate motor learning (Aiken, Fairbrother, & Post, 2012; Wulf, Raupach, & Pfeiffer, 2005). Split-screen replay features now allow for the simultaneous presentation of these modes of instructional support. It is uncertain, however, if such a combination incorporated into a self-control protocol would yield similar benefits seen in earlier self-control studies. Therefore, the purpose of the present study was to examine the effects of self-controlled split-screen replay on the learning of a golf chip shot. Participants completed 60 practice trials, three administrations of the Intrinsic Motivation Inventory, and a questionnaire on day one. Retention and transfer tests and a final motivation inventory were completed on day two. Results revealed significantly higher form and accuracy scores for the self-control group during transfer. The self-control group also had significantly higher scores on the perceived competence subscale, reported requesting feedback mostly after perceived poor trials, and recalled a greater number of critical task features compared to the yoked group. The findings for the performance measures were consistent with previous self-control research. 相似文献

This study aimed to analyze whether having more or less time to solve soccer tasks influences physical load and mental fatigue. 48 semi-professional soccer players, from teams in national leagues participated (Mage = 22.4, SDage = 2.25). They carried out 2 sessions with 4 tasks in each session. In one session, there was more time available; in the other, there was less time available. GPS technology was used to measure physical load, and an adaptation of NASA and Visual Analog Scale to measure mental load and mental fatigue. A related-samples T-test and magnitude based on inference were used to determine the possible effect. Soccer players reported that tasks with less available time were more mentally demanding. Moreover, less available time to solve the tasks significantly increased players’ RPE and decreased their Heart Rate and external physical load. Therefore, the available time significantly affects mental and physical load and mental fatigue. 相似文献
