Women are often said to exhibit an externality bias in their performance attributions. To test this hypothesis, male and female college students made effort, ability, luck, and task difficulty attributions for their performance on a recent course examination. Measures of the students' affective reactions toward their performance were also obtained. Successful students, whether male or female, made internal attributions and were pleased with their performance. Stronger internal attributions were associated with more positive affective reactions for these students. Unsuccessful female students made external attributions, were displeased with their performance, and felt better when they attributed their failure to unstable factors. Unsuccessful male students were also displeased with their performance, but tended to make more internal attributions for their failure, and felt better as a result. These findings, which suggest the influence of an internality bias among men, rather than an externality bias among women, were interpreted in terms of the male sex role.  相似文献

As counselling develops as a specialised area, counsellors are confronted with an increasing need to be effective decision-makers. Broadly speaking, counsellor decisions are of three main types: role, treatment, and responding. The need for more rigorous role decision-making has been highlighted by the challenge of the psychological educator as contrasted with the traditional interviewer model of counsellor behaviour. Whether they are operating as interviewers or educators, counsellors need to be sensitive to their treatment and responding decisions, some of which are discussed. Barriers to effective counsellor decision-making include skills deficiencies, theoretical rigidity, and debilitating rather than enabling personal vulnerability. The notion of the counsellor as decision-maker is useful for focusing the content of counsellor training, and also leads inevitably to the notion of the counsellor as an applied scientist.  相似文献

What career decision-making procedures enable people to make decisions that yield consequences congruent with their own values? The 40 “best” (most congruent) and 40 “worst” decision makers on the Career Decision Simulation were compared in a sample of 148 community college students. No significant differences appeared in the amount of double checking, number of occupations and information sources checked, amount of information collected, decision time required, and the proportion of information sought about high values. The “best” decision makers, however, were significantly more persistent in immediately seeking more information about an occupation that seemed to match one of their most important personal work values. Following a values-guided search appears more effective than simply searching exhaustively.  相似文献

The major components of Dry-Bed Training (DBT) (Azrin et al., 1974), in addition to the urine-alarm device, were identified as; (i) the waking schedule; (ii) retention control training; and (iii) positive practice and cleanliness training. Combinations of these components yielded six treatment groups. Together with an alarm-only group and a DBT group from a previous study (Bollard and Nettelbeck, 1981) these groups were compared for effectiveness in arresting bedwetting. Bedwetting frequency was reduced slightly below levels achieved with alarm-only treatment, by the addition of either retention control training, or positive practice and cleanliness training. A more substantial decrease in bedwetting resulted from the addition of the waking schedule, although none of the effects of the single components was statistically significant. The effects of the three components were cumulative, so that the more components added to the alarm-only procedure, the better the therapeutic response. Thus, the combination of waking, positive practice and cleanliness training with the alarm and the combination of all three components with the alarm (i.e. the complete DBT programme) did result in a significant reduction in bedwetting frequency compared with the alarm-only procedure. The practical and theoretical implications of these results are discussed.  相似文献

Twenty hospitalized alcoholics served as their own controls in a study which sought to compare psychophysiological and cognitive factors as mediating influences on the priming effect of alcohol. Ten subjects were independently assessed by a psychiatrist as being severely dependent on alcohol and ten as mildly or moderately alcohol dependent. Physiological, behavioural and subjective indices of the motivation to drink alcohol were employed 15 and 60 min after subjects had consumed beverages on four separate occasions corresponding to four priming conditions. These priming drinks contained either 60 ml vodka in heavy dilution or just tonic water, and in each of these conditions subjects were either led to believe that the beverages contained alcohol or they had no alcohol. The severely-dependent group displayed a degree of concordance between the indices of motivation to drink, and the levels of these tended to be significantly higher than in the less-dependent subjects. The results suggest that severely alcohol-dependent subjects were more disposed to drink 60 min after consuming alcoholic drinks than after soft drinks, regardless of whether they believed that the priming drinks had contained alcohol. Cognitive factors assumed greater importance for the drinking behaviour of less-dependent subjects, although there was evidence of discordance across behavioural, physiological and subjective measures for this group.  相似文献

Two studies were conducted in all-electric townhouses and apartments in the winter (N = 83) and summer (N = 54) to ascertain how energy conservation strategies focusing on thermostat change and set-backs and other low-cost/no-cost approaches would affect overall electricity use and electricity used for heating and cooling, the home thermal environment, the perceived comfort of participants, and clothing that was worn. The studies assessed the effectiveness of videotape modeling programs that demonstrated these conservation strategies when used alone or combined with daily feedback on electricity use. In the winter, the results indicated that videotape modeling and/or feedback were effective relative to baseline and to a control group in reducing overall electricity use by about 15% and electricity used for heating by about 25%. Hygrothermographs, which accurately and continuously recorded temperature and humidity in the homes, indicated that participants were able to live with no reported loss in comfort and no change in attire at a mean temperature of about 62 degrees F when home and about 59 degrees F when asleep. The results were highly discrepant with prior laboratory studies indicating comfort at 75 degrees F with the insulation value of the clothing worn by participants in this study. In the summer, a combination of strategies designed to keep a home cool with minimal or no air conditioning, in conjunction with videotape modeling and/or daily feedback, resulted in overall electricity reductions of about 15% with reductions on electricity for cooling of about 34%, but with feedback, and feedback and modeling more effective than modeling alone. Despite these electricity savings, hygrothermograph recordings indicated minimal temperature change in the homes, with no change in perceived comfort or clothing worn. The results are discussed in terms of discrepancies with laboratory studies, optimal combinations of video-media and personal contact to promote behavior change, and energy policies that may be mislabeled as sacrificial and underestimate the effectiveness of conservation strategies such as those investigated in these studies.  相似文献

Three experiments investigated performance as a function of the visual hemifield to which verbal and spatial stimuli were presented tachistoscopically. The aim was to relate laterality effects to individual, sex and cultural differences in spatial ability within the framework of a model of hemispheric specialisation. A left-hemisphere advantage for verbal materials was obtained but no advantage for right-hemisphere presentation of visuospatial information occurred in the following samples: British and Ghanaian (experiment 1), high and low spatial ability groups (experiment 2) and males and females (experiment 3). Traditional spatial ability tests had no predictive value for performance on the tachistocopic tasks and an interaction between presentation field and responding hand was interpreted as implying equivalent processing of spatial information in either hemisphere.  相似文献

In a between-subjects design, 46 male and 101 female Australian university students rated a target person described as male or female, overweight or average weight, and wearing glasses or not, on twelve 7-point rating scales. As predicted, a negative stereotype of the overweight person and a complex one of the person with glasses were found. However, there was no significant effect of sex of target except on the ratings of masculine and feminine and no interaction of sex of target with either the glasses or obesity variables. Nor did sex of subject influence the ratings. The results suggest that, although stereotypes of obesity and glasses do exist, they may be as severe for men as for women.  相似文献
