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 concern.  相似文献

The mathematical model associated with integrative field theory was used to infer the size of attentive fields in a task involving judgments of size. A compounded Müller-Lyer task was employed in which fins between or outside the standard shafts were systematically removed. Performance on this task was simulated by a computer that generated families of theoretical functions varying in the parameter of attentive field size. Individual theoretical functions were then correlated with an empirical function obtained from real observers. The value of attentive field size that provided the best fit between functions was then selected. The results showed that, in almost all cases, the optimum size of the attentive field was smaller for the shrinkage form than for the expansion form of the Müller-Lyer pattern, that the attentive field changed more dramatically with changes in stimulus variables in the expansion form than in the shrinkage form, and that changes in viewing distance had little effect on the optimum size of the attentive field. It was concluded that the attention was involved both in figure-ground segregation and in maintaining object constancy. The similarity of these results to data obtained in recognition and detection tasks was noted.  相似文献

Initial findings of the development of a measure of client experience of the careers guidance interview are reported. Initially based on the Medical Interview Satisfaction Scale (Wolf et al., 1978), items were derived which sampled across affective, cognitive and behavioural components of careers interviewing. The scale is pilot tested on 60 15 and 16 year-old school pupils, of low academic potential and all of whom had experienced a careers interview with a careers officer. Initial results are only partially supportive of the findings of Wolf et al. (1978). Results of a further field study of the 20-item scale based on 54 careers interviews are also reported where factor analytic data are promising. The contribution of the scale in testing related hypotheses (e.g. met expectation hypothesis) is indicated.  相似文献

Previous research has shown that young infants can discriminate both native and nonnative phonetic contrasts with ease. By 10 to 12 months of age, however, infants—like adults—typically have difficulty discriminating consonant contrasts that are not used to distinguish meaning in their native language. Although the timing of this change in speech perception has been firmly established, little is currently known about the processes or mechanisms involved in this selective and adaptive reorganization in nonnative phonetic discrimination. This study was designed to determine if there is a relation between age-related changes in speech perception performance and other developing cognitive abilities. A total of 40 8- to 10-month-old infants were tested on a nonnative consonant discrimination task and then on two additional tasks (a visual categorization task and an object search task) in an attempt to determine whether changes in nonnative consonant perception coincide with changes in these other areas of cognitive/perceptual functioning. The results indicate that changes in task performance occur in synchrony across all three tasks, and that this synchrony is not explained by simple age effects. These findings suggest that domain-general cognitive/perceptual competencies may influence developmental changes in speech perception by the end of the 1st year of life.  相似文献

The present paper reports on three outcome studies evaluating the effectiveness of a new stress management training program. In contrast to conventional stress management, which tends to emphasize life-events, the symptoms of stress and relaxation, the new program is based on emotional rumination, emotion control, and attention control. The training developed from a series of experimental studies on the role of emotional inhibition and rumination in prolonging physiological recovery from stress, and the findings reported here were obtained from a series of applied studies involving police officers from a police force in the North of England. The first two studies employed both self-reported and objective measures of change to demonstrate that the training produced significant increases in job satisfaction and reduced absenteeism, while the results of the final study showed that the benefits of the program were enhanced by follow-up training.  相似文献

Coordinated interpersonal timing in preverbal mother-child interactions is assumed to be one fundamental feature of interpersonal relatedness and the basis for parent-child bonding. The ubiquity of and early evidence for this phenomenon in ontogeny hint at its biological prewiredness and relevance for development. The quality of interpersonal timing in early preverbal parent-child interactions was hypothesized (and partially shown) to predict quality of attachment, level of cognitive functioning, and patterns of language acquisition. The aim of this study was to investigate the assumption of a facilitating effect of adequate interpersonal coordination (measured by quality of attachment) on the development of verbal communicative competence in children during the first stages of language development. On the basis of longitudinal data for 25 mother-child dyads, videotaped when the children were 17, 23, 30, and 36 months old in a free play and a short separation situation, it was investigated whether securely and insecurely attached children differ with respect to the amount of verbal contributions, their realization as alternating or simultaneous utterances, and the duration of intra-turn and inter-turn pauses. The results show that attachment was related to children's use of communicative competence especially in stressful situations, its development being paced by the age or maturation of the child.  相似文献

Women's and men's understanding of the certainty expressed in mental and modal terms was examined. Subjects were asked to decide on the location of a hidden object when the only clue available was coded in the mental or modal term used in two conflicting assertions made by a male and female experimenter, each specifying a different location. Results showed that both women and men discriminated the degree of certainty expressed in 11 of 12 pairs of terms presented. Gender differences existed in the understanding of terms which were close in pragmatic meaning, with females making the distinctions more equivocally than males. The gender of the speaker had no influence on subjects' responses to contrasts which differentiated certainty, but on the contrast in which no preference for a term was found, subjects chose the location indicated by the male experimenter significantly more often. This study highlights a point of difference in pragmatic understanding between women and men and invites explorations of its origin.This research was supported by grant 410-89-0352 from the Social Sciences and Humanities Research Council of Canada to both authors. We would like to thank Lisa Boudreau, Dana Bryant, Rob Landry, Kiran Pure, and Hal Thompson for help with various aspects of this research.  相似文献

This study examined the amount of support, encouragement, and discouragement women received from the important people in their lives when they considered enrolling in a male-traditional vocational course. Data were collected from 470 women enrolled in California vocational training programs. Approximately equal numbers of women in male-dominated (Nontraditionals) and female-dominated programs (Traditionals) completed the self-administered questionnaire. Among those in female-traditional programs, 117 had considered taking a nontraditional program, but never did (Considereds). Data were analyzed for each of these three groups. Results revealed the Nontraditionals consistently received more support and enocuragement than did the Traditionals. However, the only significant support differences between the Nontraditionals and Considereds were in terms of the males in their lives. The Considereds and Traditionals also expected more discouragement than the Nontraditionals indicated they had actually received. Recommendations are made to improve educational quality and to foster equality of educational opportunity.  相似文献
