Although serial administration of cognitive tests is increasingly common, there is a paucity of research on test-retest reliabilities and practice effects, both of which are important for evaluating changes in functioning. Reliability is generally conceptualized as involving short-lasting changes in performance. However, when repeated testing occurs over a period of years, there will be some longer lasting effects. The implications of these longer lasting effects and practice effects on reliability were examined in the context of repeated administrations of the Wechsler Memory Scale-III in 339 community-dwelling women aged 40-79 years over 2 to 7 years. The results showed that Logical Memory and Verbal Paired Associates subtests were consistently the most reliable subtests across the age cohorts. The magnitude of practice effects varied as a function of subtests and age. The largest practice effects were found in the youngest age cohort, especially on the Faces, Logical Memory, and Verbal Paired Associates subtests. 相似文献

This study fills a void in the piracy literature by describing the results of a qualitative investigation of buyers conducted in mainland China, one of the largest piracy markets in the world. Chinese college students, invited to write essays expressing their views, revealed themselves to be active buyers of fake music and movies, untroubled by any legal or ethical issues. Theories of cognitive dissonance and neoclassical economics are used to explain the behavior of buyers. A surprising result is the feeling of young Chinese that their government is unwilling and/or able to control piracy. Another insight not previously revealed in the literature is the Chinese essayists' condemnation of foreigners as hypocrites who preach against piracy while avidly buying fake goods themselves.

The current study investigated the effect of frequency of loss and awareness on the ability to make advantageous decisions in preschoolers using a child variant of the Iowa Gambling Task (Bechara, Damasio, Damasio, & Anderson, 1994). Preschoolers (N = 50) were randomly assigned to either a low loss frequency (0.1) or a high loss frequency (0.5) condition. The results suggested that increase in frequency of loss and higher awareness improved performance in the 4-year-olds. Finally, further analysis indicated that the effect of increased frequency on decision making was partially mediated by increased awareness of the game. The findings have implications for the integration of explicit and implicit processes in making adaptive choices. 相似文献

This study examined the possibility that the relationship between the number of ideas an employee generated and the number of those ideas that were adopted by the organization was moderated by the general radicalness of the employee's ideas (i.e., the extent to which the ideas were breakthrough or groundbreaking), the employee's intention to stay, psychological safety, and coworker support. Ninety-three employees generated one or more ideas and raters evaluated the radicalness and implementation of these ideas. Results showed a positive relationship between the number of ideas generated by an employee and the number adopted when the employee's ideas were generally low in radicalness. However, when an employee's ideas were generally high in radicalness, there was a positive relationship between the numbers generated and implemented only when the employee intended to remain a member of the organization or felt psychologically safe at work. The implications of these results for future research and practice are discussed. 相似文献

The goal of the current study was to examine how changes in parenting due to a parenting intervention designed to decrease permissive parenting affected the quality of children’s peer interactions. Forty-nine mothers of toddlers aged 2–3 years participated in a 12-week intervention in which half got hands-on training and practice using positive guidance in a toddler classroom setting, while the other half learned positive guidance solely via a seminar format. To observe children’s peer interactions, toddlers were divided into 8 groups of 5–7 children mixed across condition. Observers coded mothers’ empathy, permissiveness, and positive guidance parenting strategies. Children’s peer interactions were coded for antisocial behaviors, verbal aggression, physical aggression, prosocial behaviors, positive social bids, and empathy. Prior analysis of this intervention indicated that mothers in both conditions showed reductions in permissiveness over the course of the intervention. Results from the present study indicated that reductions in permissiveness predicted decreases in toddlers’ verbal aggression. Maternal empathy was a moderator such that mothers low in empathy who got hands-on training in positive guidance had children who demonstrated the greatest reductions in antisocial behaviors. 相似文献

Common-coding theory posits that (1) perceiving an action activates the same representations of motor plans that are activated by actually performing that action, and (2) because of individual differences in the ways that actions are performed, observing recordings of one’s own previous behavior activates motor plans to an even greater degree than does observing someone else’s behavior. We hypothesized that if observing oneself activates motor plans to a greater degree than does observing others, and if these activated plans contribute to perception, then people should be able to lipread silent video clips of their own previous utterances more accurately than they can lipread video clips of other talkers. As predicted, two groups of participants were able to lipread video clips of themselves, recorded more than two weeks earlier, significantly more accurately than video clips of others. These results suggest that visual input activates speech motor activity that links to word representations in the mental lexicon. 相似文献

The treatment of adolescent anorexia nervosa (AN) has improved significantly with the increased emphasis on family-based intervention. Yet despite advances, a substantial number of adolescents do not respond optimally to existing treatment models and thus there is a need for treatment alternatives that address barriers to recovery. We developed and piloted an acceptance-based separated family treatment (ASFT) with 6 adolescents with AN or subthreshold AN (eating disorder not otherwise specified, with the primary symptoms of restriction and severe weight loss). Treatment acceptability was adequate. Overall, parents rated the treatment as credible and expected improvement in their child's condition. Five of the 6 adolescents treated with ASFT restored weight to their ideal body mass index as indicated by age, height, and sex and determined by individual growth charts. Many demonstrated improved psychological health and adaptive functioning. There was evidence of broad effects, with parents reporting decreased anxiety and caregiver burden. ASFT holds promise as a treatment option for AN. The efficacy of this therapeutic approach should be tested in larger trials and compared to current family-based interventions to determine unique effects. 相似文献

The purpose of this study was to examine the association between exposure to community violence and aggression, victimization, and risk-taking behaviors among young adolescents. Secondary analysis was conducted on data from a cross-sectional survey of 8,259 sixth, seventh, and eighth grade students from eight urban schools in Texas. Results indicated that students exposed to a high level of community violence were 7.7 times more likely to carry a handgun, 5.2 times more likely to be involved in a gang were 6.4 times more likely to use marijuana, 5.3 times more likely to binge drink, and 2.8 times more likely to be injured as a result of fighting. This suggests the need for an interdisciplinary approach to violence prevention that targets all the environments of youth, including schools, homes, neighborhoods, and other community units. 相似文献

The study examined the attitudes of a sample of Zimbabwean teachers towards the inclusion of children with mild hearing impairments. Two hundred and forty-six primary school teachers participated in the study. The teachers completed the modified Attitude Toward Mainstreaming Questionnaire (ATMQ) (Larrivee & Cook, 1979). In addition, they also completed four measures on implementation concerns of inclusive education of children with mild hearing impairments (i.e., academic, management, social, and knowledge concerns). Analysis related the scores from these four measures to teachers' attitudes, school type, class sizes, professional qualifications and position in the school. Compared with teachers with lower professional qualifications, teachers with higher professional qualifications had more favourable attitudes towards children with hearing impairment. Teachers who taught at ordinary schools with special needs resource units had more favourable attitudes towards students with hearing impairment than those at schools without such units. Resource unit teachers welcomed social inclusion of children with mild hearing impairments. School administrators were concerned about the practice of including children with hearing impairments in regular school setting before inducting teachers. 相似文献

The study analysed the relationships between teacher ratings and standardised test scores in Reading and Mathematics for students receiving learning support for learning difficulties (n = 60, mean age= 16.3). Teacher ratings were found to significantly predict pupils' performance in Reading. Students with extended learning support had significantly higher teacher attainment ratings in both Reading and Mathematics. Teacher judgment ratings combined with standardized test scores were reliable for assessing instructional effectiveness. Standardised tests were more reliable than teacher ratings in assessing academic attainment. 相似文献
