Objectives: Obesity is a rising problem in adolescents related to unhealthy behaviours. Commitment devises are one type of behavioural intervention that may help people change their behaviours. The current pilot trial tests whether commitment devices delivered via text message help adolescents maintain their recent weight loss.
Methods: During a 12-week pilot trial, adolescents who attended a weight loss camp were randomly assigned to either received text messages that contained only information, i.e. advice, about weight loss management (n = 13) or asked for them to commit to following the same advise (n = 14).
Results: The BMI of the adolescents in the commitment group did not change. In contrast, the BMI of adolescents in the information group increased. A linear regression revealed that group was a significant predictor of BMI change. A logistic regression revealed that adolescents in the information group were nearly eight times more likely to regain weight than those in the commitment group.
Conclusions: This is the first study with adolescents to show weight maintenance using a commitment device. The results suggest that commitment devices can help adolescents maintain their recent weight loss. 相似文献
False remembering has been examined using a variety of procedures, including the Deese-Roediger-McDermott procedure, the false fame procedure and the two-list recognition procedure. We present six experiments in a different empirical framework examining false recognition of words included in the experimental instructions (instruction-set lures). The data show that participants' false alarm rate to instruction-set lures was twice their false alarm rate to standard lures. That result was statistically robust even when (1) the relative strength of targets to instruction-set lures was increased, (2) participants were warned about the instruction-set lures, (3) the instruction-set lures were camouflaged in the study instructions and (4) the instruction-set lures were presented verbally at study but visually at test. False recognition of instruction-set lures was only mitigated when participants were distracted between encountering the instruction-set lures and studying the training list. The results confirm the ease with which recognition succumbs to familiarity and demonstrate the robustness of false recognition. 相似文献
Through individual-to-group generalisation, information about individual members of stigmatised social groups changes the outgroup judgment. This article reports meta-analytic reviews of over 30 years of experimental, lab-based research on individual-to-group generalisation (107 independent tests; 5393 participants). In a first meta-analysis, a positive, medium-size generalisation effect was detected (r = .28, p < .001), reflecting significant generalisation of outgroup exemplar information to the outgroup judgment. This effect was moderated by the number of exemplars and exemplar typicality, with more moderately atypical exemplars maximising generalisation effects. Several other design parameters—including type of control condition, generalisation measures, mode of information provision, type of target outgroup and origin of study—did not moderate the positive generalisation effect. A second meta-analysis investigated the interplay between metacognitions and generalisation and found assimilation effects with metacognitive triggers encouraging exemplar inclusion, and contrast effects with metacognitive cues encouraging exemplar exclusion. These results demonstrate that the same outgroup exemplar can lead to bias reduction or bias exacerbation, depending on available meta-cognitive cues. Findings are discussed in terms of implications for intergroup psychology, generalisation theory and bias reduction interventions. 相似文献

Data from 396 real estate salespeople offer structural model evidence of the antecedence of salesperson cognitive style (Jung, 1971) to adaptive selling behavior, and to sales orientation-customer orientation and self-perceived selling performance. Four hypotheses were supported: Salespeople who prefer information intake by intuiting (rather than sensing) and information processing/decision-making by thinking (rather than feeling) were found to be more likely to practice adaptive selling; the more adaptive selling was practiced, the greater customer orientation became; and the greater the customer orientation, the better the self-perceived selling performance. Implications exist for salesperson training, management, and motivation research. 相似文献

A detailed psychophysiologic analysis of a vasovagal faint occurring in a “blood-injury-illness” phobic demonstrated that the syncopal episode consisted of a diphasic response. This lends support to the hypothesis that vasovagal fainting in these patients is caused by an overcompensating rebound parasympathetic activation following sympathetic arousal. Treatment and research implications of this finding are discussed. 相似文献
This paper examines the implications of recent theory and research in cognitive psychology for the understanding and assessment of intelligence. Three major themes are developed. The first has to do with how changes in the social and educational climate for testing can influence the conception of intellectual competence and the technology of testing. The second theme concerns the ways that cognitive psychology, with its emphases on memory, problem-solving, and knowledge acquisition, has begun to provide a new framework for viewing differences in intellectual functioning. Finally, it is argued that study of the kinds of performances required for success in school suggests ways in which intelligence testing can be made more responsive to current social and educational needs. 相似文献
