Sudden visual changes attract our gaze, and related eye movement control requires attentional resources. Attention is a limited resource that is also involved in working memory??for instance, memory encoding. As a consequence, theory suggests that gaze capture could impair the buildup of memory respresentations due to an attentional resource bottleneck. Here we developed an experimental design combining a serial memory task (verbal or spatial) and concurrent gaze capture by a distractor (of high or low similarity to the relevant item). The results cannot be explained by a general resource bottleneck. Specifically, we observed that capture by the low-similar distractor resulted in delayed and reduced saccade rates to relevant items in both memory tasks. However, while spatial memory performance decreased, verbal memory remained unaffected. In contrast, the high-similar distractor led to capture and memory loss for both tasks. Our results lend support to the view that gaze capture leads to activation of irrelevant representations in working memory that compete for selection at recall. Activation of irrelevant spatial representations distracts spatial recall, whereas activation of irrelevant verbal features impairs verbal memory performance.  相似文献

Abstract

In a sample of 97 male adolescents, individual differences in health complaints were predicted by personality traits and by self-reported health/risk behaviors. Anxiety and loneliness were measured at Times 1 and 2, and health locus of control, various behaviors and health complaints were assessed at the end of the two-year study. A causal model was specified, employing anxiety and loneliness as distal predictors, health locus of control and behaviors as proximal predictors of health complaints. It turned out that anxiety was the most powerful single predictor, and that loneliness exerted a direct effect on health locus of control and behaviors and an indirect effect on health complaints. Risk behavior as well as health behavior were related to complaints. Social integration facilitated not only health behavior but also risk behavior.  相似文献

Objective: This study investigated the role of coping plans and the use of selection, optimisation and compensation (SOC) strategies within an experimental evaluation of a 26-week physical exercise intervention.

Methods: Older women (N?=?86, M age?=?73.7 years) were randomly assigned to a telephone-assisted or a self-administered coping planning intervention after 6 weeks’ participation in an exercise programme. The number of different coping plans formulated, exercise-specific SOC strategy use and their interaction were used to predict objectively measured long-term adherence to the intervention.

Results: The number of coping plans formulated (β?=?0.28) and goal-pursuit strategies reported (sum score of optimisation and compensation strategies, β?=?0.39) predicted adherence to the exercise programme over 20 weeks. The predictive strength of coping plans increased with decreasing numbers of goal-pursuit strategies (β?=??0.21). Women supported via telephone reported significantly more coping plans than did women in the self-administered coping planning group, F(1,80)?=?9.47, p?=?0.003.

Conclusion: Coping plans have a buffering effect on adherence levels when use of SOC strategies is low. Older women's adherence to physical activities may be improved if they are given direct support in generating coping plans involving strategies of selection, optimisation and compensation.  相似文献

Basketball referees' decisions in ambiguous situations are supposed to adhere to common standards. We propose that standards can be established by video training-programs. Thirty-three German elite basketball referees participated in an online experiment. Feedback during a learning phase influenced decisions (foul vs. no call) in a subsequent test phase. These results provide a starting point for further investigations into establishing standards for referees. They suggest that establishing standards for referees' decisions in ambiguous situations may be a worthwhile approach for improving the quality of referees' decisions.  相似文献

The purpose of this study was to investigate coaches’ perceptions on the impact of a coach training program designed to promote youth developmental outcomes. Participants were coaches of youth sport teams. Multiple methods were used to collect data. Coaches reported many benefits for themselves, their athletes, and their teams. They reported an increase in knowledge and a better understanding of their players. Participants perceived that the activities promoted cohesion and communication, while also contributing to the development of athlete competence, confidence, connection, and character/caring. The results provide guidance for creating and delivering coach training programs designed to promote youth developmental outcomes.  相似文献

ABSTRACT

Many correlative and experimental studies indicate that the portrayal of alcohol in the mass media impacts viewers’ alcohol expectancies, attitudes, and behaviors. Based on social cognitive theory, the portrayed consequences and the valence of the character experiencing these consequences are important to consider when investigating the portrayal of alcohol in the mass media. However, experimental studies manipulating character valence and consequences are scarce. This study presents an experimental examination of an adult sample, manipulating the occurrence of consequences (no consequences, positive consequences, and negative consequences), as well as character valence (a positive or negative character). We investigated the effects of media portrayals on positive and negative alcohol expectancies, as well as on attitudes toward alcohol. Furthermore, the moderating role of participants’ level of alcohol consumption was considered. We found main effects only on the negative alcohol expectancies, supporting the differentiation of alcohol expectancies and attitudes. However, the valence of the depicted character did not moderate the impact of the portrayed consequences. Interaction effects of participants’ individual levels of alcohol consumption and portrayals of consequences of alcohol consumption in the mass media were uncovered. This finding has important implications for further research and prevention efforts directed at risk groups.  相似文献

Planning interventions have proven effective to change behaviour. However, less is known about their underlying mechanisms. To better understand the processes by which planning interventions unfold their effects, a combined action planning and coping planning intervention was tested in a field setting, with the focus on mediating and moderating effects of theory‐derived social‐cognitive variables. In a randomized controlled trial, 374 employees of a logistics company were asked to participate in either a combined action planning and coping planning intervention or an active control group. Four weeks later, self‐reported changes in fruit and vegetable intake, action planning, coping planning, intentions and self‐efficacy were measured. Single and simultaneous mediating effects on behaviour were tested with intention‐to‐treat analyses, along with interaction effects between planning processes. Action planning and coping planning mediated intervention effects on fruit and vegetable intake not only separately, but also simultaneously (multiple mediation). Action planning and coping planning had main and interactive effects on behaviour change (moderation). Action planning and coping planning may exert both additive and synergistic effects on health behaviour change. Volitional interventions should include both action planning and coping planning components and stimulate the use of planning in everyday life. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献

The presence of cognitive impairment has been documented for a large number of diseases, conditions and mental disorders. Due to their impact on functioning in professional life and in everyday activities, there appears to be an increasing demand of qualified neuropsychological examinations in civil forensic contexts. While neuropsychological testing is the method of choice for determining the presence and the profile of cognitive impairment, it is easy to underperform in such tests. The authenticity of test results has to be thoroughly checked using modern approaches of symptom validity assessment. Without adequate validity checks, forensic psychological examinations are incomplete.  相似文献

Following up on an exchange about the relation between microsaccades and spatial attention (Horowitz, Fencsik, Fine, Yurgenson, & Wolfe, 2007; Horowitz, Fine, Fencsik, Yurgenson, & Wolfe, 2007; Laubrock, Engbert, Rolfs, & Kliegl, 2007), we examine the effects of selection criteria and response modality. We show that for Posner cuing with saccadic responses, microsaccades go with attention in at least 75% of cases (almost 90% if probability matching is assumed) when they are first (or only) microsaccades in the cue—target interval and when they occur between 200 and 400 msec after the cue. The relation between spatial attention and the direction of microsaccades drops to chance level for unselected microsaccades collected during manual-response conditions. Analyses of data from four cross-modal cuing experiments demonstrate an above-chance, intermediate link for visual cues, but no systematic relation for auditory cues. Thus, the link between spatial attention and direction of microsaccades depends on the experimental condition and time of occurrence, but it can be very strong.  相似文献
