Hypotheses about the preference for opponents in competitive situations, about performance under various win-loss ratios, and about task and opponent satisfaction under various win-loss ratios were tested. A 5 × 5 latin square with four replications and a repeated measure factor of trials was the design used with 20 female college students as subjects. The five different win percents were W10, W30, W50, W70, and W90. A manipulative maze task was used with subjects receiving 20 trials against each of five confederate opponents. Results indicated that (a) when a person knows little or nothing about her ability level she initially prefers to compete with opponents of low ability but with each subsequent contest opponents of higher ability levels are preferred; (b) subjects performed better in the W50 condition; (c) task satisfaction is higher when the percent of wins is equal to or greater than the percent of losses; and (d) opponent satisfaction is greater for opponents who perform equal to or better than the subject. 相似文献

Two studies tested the hypotheses (1) that focusing on the process of goal pursuit is associated with lower levels of procrastination and (2) that this relationship is moderated by fear of failure and task aversiveness. Study 1 used a between-subjects design with hypothetical scenarios (N = 92). Study 2 used a 5-week longitudinal within-subject design in a real-life context (N = 50). Both studies found converging evidence for the main-effect hypothesis, that is, process focus is negatively associated with procrastination in the academic context (e.g., studying for an exam). Process focus was also negatively related to task aversiveness and fear of failure. However, findings regarding moderation effects of fear of failure and task aversiveness were mixed. Taken together, findings support the hypothesis that the cognitive representation of a goal primarily in terms of its means (i.e., process focus) versus its outcome is related to less procrastination: Focusing on the process of a task can help to reduce procrastination. 相似文献

During the last years increasing attention has been paid to young children and adolescents with sexual coercive behaviour. During the year 2007 altogether 232 boys and 30 girls under the age of 14 years were reported to the police because of sexual assaults. In NRW an increasing number of in- and out-patient institutions offers specific and unspecific treatment programs for these children. The major aim of our study, which is supported by the Ministry of Employment, Health and Social Affairs of the state of NRW, is to evaluate the wide range of different treatment programs and to find predictors for successful or difficult treatment outcomes. Furthermore we are interested in differences between children with sexual problem behaviour and children with exclusively aggressive problems. So far 23 institutions take part in our research project and our total sample currently consists of 75 boys between 9 - 15 years. A psychometric test battery is applied at the beginning of individual treatment. Our first results highlight differences in socio-demographic data between children with sexual coercive behaviour and children with exclusively aggressive behaviour problems. Compared to children with exclusively aggressive problem behaviour, children with sexual problem behaviour come more often from incomplete families with no male parent, have experienced more psychological and physical violence and have been more often victims of sexual abuse. Compared to children with exclusively aggressive behaviour problems they score significantly higher on the “Depression / Anxiety” scale of the SPS-J, although average T-scores for both groups are within the normal range. Regarding cognitive functioning there are no significant differences between both groups. 相似文献

The purpose of this study is to see how feelings of anticipated support arise in church. Anticipated support refers to the belief that coreligionists will provide assistance in the future if the need arises. This model contains the following hypothesis: (1) people who affiliate with conservative Protestant congregations will be more deeply committed to their faith, (2) individuals who are more committed to their faith will attend church more frequently, (3) people who go to church more often will be more likely to occupy church service roles, (4) those who occupy church service roles will feel more highly valued by their coreligionists, (5) individuals who feel they are valued highly by fellow church members will receive more emotional support from them, and (6) people who receive more emotional support at church will have stronger anticipated support beliefs. Data from a nationwide survey of older Mexican Americans support these hypotheses. 相似文献
