Using developmental principles to assist preschoolers in developing numeracy and literacy 总被引:1,自引:0,他引:1
In a yoked control design, 4-yr.-olds (N = 39) in a Head Start program played numerous structured games involving either the oddity principle or letter identification and letter sounds. The children's mean age was 53.2 mo.; SD = 4.1 mo. Three were Middle Eastern, 14 were Latino, 7 were East African, and 15 were African American. Children showed better mastery of oddity after playing games directed at this concept, and numeracy scores on the Woodcock-Johnson III were better for children who had played this type of game. Woodcock-Johnson III Letter-Word scores for children who had played the oddity and seriation or letter games were equivalent. These results are consistent with other research indicating that the understanding of oddity relations may be a key transitional thinking which supports quantitative and verbal development at the preschool-kindergarten interface. The standardized test scores indicate that guided play directed at this aspect of cognitive growth or more narrowly directed at early literacy can produce equivalent knowledge of letters. 相似文献

We tested the efficacy of a social skills training program for the parents of school-aged children experiencing socio-emotional
problems. Participating families (N = 42) were randomly assigned to one of three conditions: parent social skills training; parent plus parallel child social
skills training; or no-treatment control. The two treatment groups did not differ on any of the outcome measures. Treatment
was associated with improvements in parent and child social skills knowledge, parent social problem solving, and child emotional
functioning. In follow-up analyses examining mechanisms of change, parental attendance and change in child social skills knowledge
predicted response to treatment. Overall, our results highlight the utility of engaging parents as primary participants in
the treatment of children’s socio-emotional problems and suggest methods for maximizing the impact of such an intervention. 相似文献

Prospective memory is critical to everyday functioning and can be vulnerable to distraction. We conducted an experiment to
explore whether we could buffer prospective memory against distraction. For half the participants, we preexposed stimuli that
were later designated as prospective memory targets. Then, all participants performed an ongoing task (in which the prospective
memory task was embedded) under standard and high attentional demand (i.e., under full and divided attention). Target preexposure
improved prospective memory and eliminated the significant divided attention effect. Thus, target preexposure seems to buffer
prospective memory against the disruptive effect of dividing attention. Moreover, target preexposure seemed to help participants
to respond with the correct intended action. This result implies that preexposure to the target stimuli facilitated the encoding
of an association between the target stimuli and the intended action, perhaps promoting relatively more reflexive retrieval
and thereby buffering prospective memory against distraction. 相似文献

Cognitive-behavioral therapy (CBT) incorporating exposure and response prevention is a first line treatment for obsessive-compulsive disorder (OCD). Although, the efficacy of CBT in reducing OCD symptoms is well documented, less is known about its effects on quality of life (QOL). In the current study, functional impairment aspects of QOL (as measured by the Sheehan Disability Scale) were assessed among 70 adult outpatients with OCD before and after CBT. Statistically significant improvements in QOL and large pre- to post-treatment effect sizes were observed for work, social, and family functioning. Improvements in social and family functioning were predicted by improvements in OCD symptom severity even after controlling for improvements in depressive symptoms. In addition, clinically significant change in OCD symptoms and QOL were highly related, although there was a subset of participants whose symptoms improved without corresponding improvements in QOL. These results suggest that the effects of CBT may extend beyond OCD symptom reduction to QOL. 相似文献

Preschoolers monitor the relative accuracy of informants 总被引:3,自引:0,他引:3
In 2 studies, the sensitivity of 3- and 4-year-olds to the previous accuracy of informants was assessed. Children viewed films in which 2 informants labeled familiar objects with differential accuracy (across the 2 experiments, children were exposed to the following rates of accuracy by the more and less accurate informants, respectively: 100% vs. 0%, 100% vs. 25%, 75% vs. 0%, and 75% vs. 25%). Next, children watched films in which the same 2 informants provided conflicting novel labels for unfamiliar objects. Children were asked to indicate which of the 2 labels was associated with each object. Three-year-olds trusted the more accurate informant only in conditions in which 1 of the 2 informants had been 100% accurate, whereas 4-year-olds trusted the more accurate informant in all conditions tested. These results suggest that 3-year-olds mistrust informants who make a single error, whereas 4-year-olds track the relative frequency of errors when deciding whom to trust. 相似文献

In 3 studies, the authors tested the hypothesis that Chinese participants would view social groups as more entitative than would Americans and, as a result, would be more likely to infer personality traits on the basis of group membership--that is, to stereotype. In Study 1, Chinese participants made stronger stereotypic trait inferences than Americans did on the basis of a target's membership in a fictitious group. Studies 2 and 3 showed that Chinese participants perceived diverse groups as more entitative and attributed more internally consistent dispositions to groups and their members. Guided by culturally based lay theories about the entitative nature of groups, Chinese participants may stereotype more readily than do Americans when group membership is available as a source of dispositional inference. 相似文献

Telephone versus print delivery of an individualized motivationally tailored physical activity intervention: Project STRIDE. 总被引:3,自引:0,他引:3

OBJECTIVE: Given that only 25% of Americans meet physical activity recommendations, there is a need to develop and disseminate effective, evidence-based interventions to promote physical activity. The authors tested 2 delivery channels, telephone and print, to determine whether one was more effective in promoting physical activity. DESIGN: The authors randomly assigned 239 healthy, sedentary adults to (a) telephone-based individualized feedback, (b) print-based individualized feedback, or (c) contact control. Both intervention arms were guided by a motivationally tailored, theoretically driven computer expert system. MAIN OUTCOME MEASURES: Physical activity as measured by the 7-day Physical Activity Recall interview. RESULTS: At 6 months, both telephone and print arms significantly increased in minutes of moderate intensity physical activity compared with control, with no differences between the intervention arms. At 12 months, print participants reported a significantly greater number of moderate intensity minutes than both telephone and control participants, who did not differ. CONCLUSION: Results suggest that both telephone and print enhance the adoption of physical activity among sedentary adults; however, print interventions may be particularly effective in maintaining physical activity in the longer term. 相似文献

Ongoing physical activity advice by humans versus computers: the Community Health Advice by Telephone (CHAT) trial. 总被引:4,自引:0,他引:4

PURPOSE: Given the prevalence of physical inactivity among American adults, convenient, low-cost interventions are strongly indicated. This study determined the 6- and 12-month effectiveness of telephone interventions delivered by health educators or by an automated computer system in promoting physical activity. DESIGN: Initially inactive men and women age 55 years and older (N = 218) in stable health participated. Participants were randomly assigned to human advice, automated advice, or health education control. MEASURES: The validated 7-day physical activity recall interview was used to estimate minutes of moderate to vigorous physical activity. Physical activity differences by experimental arm were verified on a random subsample via accelerometry. RESULTS: Using intention-to-treat analysis, at 6 months, participants in both interventions, although not differing from one another, showed significant improvements in weekly physical activity compared with controls. These differences were generally maintained at 12 months, with both intervention arms remaining above the target of 150 min per week of moderate to vigorous physical activity on average. CONCLUSION: Automated telephone-linked delivery systems represent an effective alternative for delivering physical activity advice to inactive older adults. 相似文献

Evidence has begun to accumulate showing that successful performance of event-based prospective memory (PM) comes at a cost to other ongoing activities. The current study builds on previous work by examining the cost associated with PM when the target event is salient. Target salience is among the criteria for automatic retrieval of intentions according to the multiprocess view of PM. An alternative theory, the preparatory attentional and memory processes theory, argues that PM performance, including retrieval of the intent, is never automatic and successful performance always will come at a cost to other ongoing activity. The 4 experiments reported here used a salient PM target event. In addition, Experiments 3 and 4 were designed to meet the stringent criteria proposed for automatic retrieval of intentions by multiprocess theory, and, yet, in all 4 experiments, delayed intentions interfered with ongoing task performance. 相似文献
