Three studies are presented testing a model of the cognitive performance deficits shown in depression. The model proposes that such deficits occur as an interaction of expectancy and focus of attention variables, that is, in the presence of both low expectancy of success and high self-focus. Study 1 was a pilot study which documented that depressed undergraduates evidence poorer anagram performance, greater self-focus, and lower pretask expectancies than do nondepressed subjects. Study 2 showed that nondepressed undergraduates evidence performance deficits only when both expectancy is lowered and self-focus is increased. Study 3 suggested that depressed undergraduates' performance deficits are overcome either by lowering self-focus or by raising expectancy. Discussed are discrepancies between self-report and performance data, the relevance of these studies to the test anxiety literature, the need to integrate literature concerning the effects of depression, anxiety, and self-esteem on performance, and how the interactive roles of positive expectancy and focus of attention may be related to effective coping in a variety of situations.  相似文献

Wearing costumes is a common experience during early childhood and is often important to sociodramatic play. Costumes tend to be highly gendered for both girls and boys (such as princess and superhero costumes). However, there is very little research on the impact that wearing costumes has on gender-differentiated behavior, such as toy preference, prosocial behavior, or perseverance during early childhood. The current study included 223 U.S. children, aged between 3 and 5 years-old. Children were assigned to wear either a gendered, counter-gendered, or gender-neutral costume, and they then took part in three gender-related tasks. There was no impact of wearing costumes on any task for girls. However, boys preferred feminine toys significantly more when wearing a neutral costume when compared to a masculine-typed one. Additionally, boys were significantly less likely to help when wearing a masculine-typed costume compared to a feminine-typed costume. There are several implications of these findings that are discussed in the paper. Parents may wish to purchase a wide range of costumes for their child for sociodramatic play, particularly for boys. Therapists could also potentially use costumes during play therapy to discuss gender issues. Additionally, costume producers could consider marketing a wide range of costumes for children as opposed to largely focusing on gendered ones.

Sanders et al.'s proposal for a management framework for conflicting interests among program developers is very welcome. The underlying principles of such a framework must nevertheless prioritise the need for researchers and commissioners of services to make objective assessments of the impact of interventions reported in journal articles. This is particularly important in the field of randomised trials which may influence public sector expenditure. Using a strict definition derived from known financial conflict of interest, we have demonstrated that child-based effect sizes are much lower for independent studies than for studies with developer involvement. On this basis, we propose that journals publishing evaluations of psychosocial interventions should agree a standardised format for declarations of conflicts of interest based on that recommended by the International Committee of Medical Journal Editors.  相似文献

31 college age men and women who consume less than three caffeinated beverages per week agreed to participate as subjects in research on the effects of acute caffeine intake on low intensity task performance. All subjects performed two randomly administered test conditions: (1) caffeine (5 mg/kg) and (2) placebo on separate visits following an initial 1-hr. orientation visit. Subjects were administered the beverage 30 min. prior to performing 12 separate tests assessing basic mathematics, simple response, logical reasoning, hand-eye coordination, and spatial and assembly skills. The Spielberger State Anxiety test was administered immediately after consuming the test beverage and once again at posttest. Analysis showed that caffeine did not significantly affect performance on all tests with the exception of the peripheral awareness (hand-eye coordination) test on which performance was higher after ingesting caffeine. The placebo treatment produced no effect on state anxiety, which contrasted with a significant rise in anxiety after caffeine consumption. State anxiety values were significantly greater after caffeine treatment relative to the placebo at pretest, and this difference persisted at posttest. These results demonstrated that the dose of caffeine increased scores on state anxiety for individuals who consumed less than three caffeinated beverages weekly but had very little effect on performance of low intensity tasks, except for a hand-eye coordination test involving peripheral awareness. Perhaps longer continuous performance of more demanding tasks would be more sensitive.  相似文献

Various studies have found that viewing physical or relational aggression in the media can impact subsequent engagement in aggressive behavior. However, this has rarely been examined in the context of relationships. Accordingly, the aim of this study was to examine the connection between viewing various types of aggression in the media and perpetration of aggression against a romantic partner. A total of 369 young adults completed a variety of questionnaires asking for their perpetration of various forms of relationship aggression. Participants' exposure to both physical and relational aggression in the media was also assessed. As a whole, we found a relationship between viewing aggression in the media and perpetration of aggression; however, this depended on the sex of the participant and the type of aggression measured. Specifically, exposure to physical violence in the media was related to engagement in physical aggression against their partner only for men. However, exposure to relational aggression in the media was related to romantic relational aggression for both men and women.  相似文献

Although content analyses have found that superhero programs in the media portray strong gender stereotypes of masculinity, little research has examined the effects of viewing such programs. In the current study, 134 mothers of preschool children (from the Western and Northwestern United States) reported their child’s superhero exposure in the media, male-stereotyped play, weapon play, and parental active mediation of the media at two time points (1 year apart). Results revealed that boys viewed superhero programs more frequently than girls, with nearly a quarter of boys viewing superhero programs at least weekly. Analyses revealed that superhero exposure was related to higher levels of male-stereotyped play for boys and higher levels of weapon play for both boys and girls from Time 1 to Time 2, even after controlling for initial levels. Parental active mediation did not negate these effects, and even served to strengthen one finding for girls. Specifically, among girls with high superhero exposure, weapon play was highest for girls who received frequent active mediation. Implications of the results are discussed with a focus on whether such programs are developmentally appropriate for preschool children.  相似文献
