摘要:

Exercise has important health benefits, but a large proportion of the population is physically inactive. We examined the prevalence of stages of readiness to exercise and their relationship to self‐efficacy and to the costs and benefits of exercising in samples of 1093 employees in and around Providence, Rhode Island, and 801 employees in Adelaide, Australia. In both samples, 40.6% of respondents had not yet begun to take action (not thinking about starting to exercise or thinking about it but not doing it), while 59.4% were at some phase of action (exercising some, starting to exercise regularly, exercising regularly). Scores on self‐efficacy items and cost‐and‐benefit items significantly differentiated employees at extreme stages. In contrast with those who exercised regularly, employees who had not yet begun to exercise had little confidence in their ability to exercise and saw exercising as having nearly as many costs as it had benefits. There is the potential to enhance the impact of exercise interventions by targeting them so as to address factors related to these different stages of readiness to e

摘要:

Individuals often report experiences that conform to objective definitions of sexual harassment, but rarely report the subjective perception that they have been sexually harassed. The present research proposed that individual difference factors may mediate this commonly observed discrepancy. It was hypothesized that erotophobia, sexual inexperience, youth, sex role traditionality, repressing defensive style, and need for social approval have a weak inhibitory effect on reports of objectively defined experiences of sexual harassment, but a strong inhibitory effect on subjective perceptions that one has been sexually harassed. Results showed that individual difference factors including erotophobia, repressing defenses, and need for social approval were associated with fewer reported objective experiences of sexual harassment, while the base rate of subjective perception that one had been sexually harassed was very low, and this subjective perception was generally unassociated with individual difference factors. Discussion focuses on individual difference characteristics and motivation to ignore or to fail to report objective experiences of sexual harassment, and on suggestions for further research into the very high base rate of objectively defined experiences of sexual harassment and the very low base rate of perceived sexual harassment.

摘要:

Psychological symptoms were found to be associated with a number of cognitive appraisal and demographic variables but predicted primarily by perceived lack of control among information seekers in the aftermath of the Three Mile Island accident. Cognitive appraisal variables were found to be interrelated in a way which suggests that appraisal of control and faith in experts mediate between perceived environmental threat and psychological symptoms among information seekers in the aftermath of technological disaster. Demographic variables such as education and evacuation status are viewed as mediators between environmental circumstances and cognitive appraisals.

摘要:

Coping strategies endorsed by adolescents in dealing with a potential threat to their health were assessed in a study which investigated components of protection motivation theory. Year 9 and 10 high school students were presented with information about cardiovascular disease risk and the role of exercise in maintaining cardiorespiratory fitness. Three components specified by the theory were manipulated: response efficacy (effectiveness of exercise in preventing cardiovascular disease), response costs (costs associated with taking up a regular program of exercise) and self‐efficacy (belief in ability to carry out a program of exercise) in a 2 × 2 × 2 factorial design with two levels (high vs. low) of each variable. It was hypothesized that such information would affect participants' perceptions of response efficacy, response costs, self‐efficacy, and their selection of coping strategies. Six dependent variables were investigated: two adaptive coping strategies (behavioral intention to exercise, rational problem solving) and four maladaptive strategies (avoidance, wishful thinking, hopelessness, arid fatalism). Manipulation checks found significant differences between the high and low conditions of each independent variable. Adaptive strategies were strongly endorsed, whereas endorsement of the maladaptive strategies ranged from minimal to complete disagreement. Participants in the high self‐efficacy condition indicated stronger intentions to exercise. Students in the low response efficacy condition demonstrated more endorsement of hopelessness and fatalism than did students in the high response efficacy condition. When exercising status was included as a fourth independent variable, it was found that active adolescents endorsed the adaptive coping strategies more strongly than did inactive adolescents. The cognitive coping strategies adopted by adolescents when dealing with perceived threats to their health may be influenced by information on the efficacy of relevant behavior, by perceptions of their ability to perform such behavior, and by their actual involvement with the behavior of

摘要:

Loftus (1974) had subjects read summaries of criminal trials that contained the testimony of either credible or discredited prosecution eyewitnesses, and found no effect of discrediting an eyewitness. Instead, almost as many subjects voted guilty with a discredited eyewitness as with a credible eyewitness; this led Loftus to the conclusion that jurors tend tooverbelieveeyewitness testimony. Loftus's conclusion was subsequently challenged by others who reported a strong discrediting effect. A series of three experiments using college students was conducted to explore the characteristics of trial summaries that might account for the discrepancy in results, such as inclusion of judicial instructions concerning proof beyond a reasonable doubt, or an eyewitness's reaffirmation of his testimony following discrediting. In all cases, a strong discrediting effect was found. Apparently the discrediting effect appears regardless of wide variation in content of trial summaries. The present data do not support the overbelief claim.
