The authors used recursive partitioning methods to identify combinations of baseline characteristics that predict 2-year physical activity success in each of 3 physical activity interventions delivered in the multisite Activity Counseling Trial. The sample consisted of 874 initially sedentary primary care patients, ages 35-75 years, who were at risk for cardiovascular disease. Predictors of 2-year success were specific to each intervention and represented a range of domains, including physiological, demographic, psychosocial, health-related, and environmental variables. The results indicate how specific patient subgroups (e.g., obese, unfit individuals; high-income individuals in stable health) may respond differently to varying levels and amounts of professional assistance and support. The methods used provide a practical first step toward identifying clinically meaningful patient subgroups for further systematic investigation. 相似文献

Self‐explaining is an effective metacognitive strategy that can help learners develop deeper understanding of the material they study. This experiment explored if the format of material (i.e., text or diagrams) influences the self‐explanation effect. Twenty subjects were presented with information about the human circulatory system and prompted to self‐explain; 10 received this information in text and 10 in diagrams. Results showed that students given diagrams performed significantly better on post‐tests than students given text. Diagrams students also generated significantly more self‐explanations that text students. Furthermore, the benefits of self‐explaining were much greater in the diagrams condition. To discover why diagrams can promote the self‐explanation effect, results are interpreted with reference to the multiple differences in the semantic, cognitive and affective properties of the texts and diagrams studied. 相似文献

While previous research has mainly emphasised the importance of leader–member exchange (LMX) to job satisfaction, there is a lack of research on reciprocal relationships between job satisfaction and LMX. In this study, we not only suggest that good LMX increases job satisfaction, but that job satisfaction can also enhance high‐quality supervisor–employee relationships. A full cross‐lagged panel analysis was used to test reciprocal relationships between LMX and job satisfaction. Employees (N= 279) of a large information technology company filled out questionnaires at two times, with a time lag of 3 months. In line with our predictions, findings revealed a positive relationship between LMX and job satisfaction both at Time 1 and Time 2. Moreover, LMX at Time 1 predicted the increase of job satisfaction at Time 2, and job satisfaction at Time 1 predicted the increase of LMX at Time 2. The results demonstrate the need to consider reciprocal relationships between job satisfaction and LMX when explaining employees' workplace outcomes. Our findings are discussed in terms of positive psychology theory. 相似文献

The present study examined the effect of gender-typed labeling of a task on the performance of children. A total of 72 boys
and girls aged 11, 13 and 16 years took part in the study. The same measure of performance—a perceptual motor task—was used
across all conditions. Two main dimensions were investigated: first, the effect of of directly labeling the task as gender
appropriate or inappropriate; second, the effect of the instruction to role-enact a person competent at the task labeled gender
appropriate or inappropriate. The results indicate that children of all ages studied perform better at the task labeled gender
appropriate rather than inappropriate. Children also perform better when role-acting competence at a gender-typed labeled
task than under conventional testing procedures. The implications of these findings are discussed. 相似文献

This article reports an experiment to investigate the idea that time-of-day differences in memory for text are related to
type of text processing that is carried out at different times of day. In particular, it was hypothesized that subjects tested
in the morning tend to retain more of the exact wording of the text, whereas those tested in the afternoon are more likely
to produce a meaning-based representation. The results of a recognition test showed that, in agreement with other studies,
immediate text memory is better in the morning than in the afternoon. As predicted, the subjects tested in the morning better
remembered the exact wording of the original passages. However, the idea that memory for meaning is better in the afternoon
than the morning was not supported by the data. The results suggest that subjects at both times of day produce a meaning-based
representation of the text but, in the morning, this representation is supported by good verbatim memory, enabling accurate
recall of the text at that time. 相似文献

24 women over 60 yr. and 24 younger women rated the severity of life stress events drawn from a pool of events occurring to elderly people. There were no over-all age differences, but rather strong agreement on which events were most threatening. There was some evidence, however, that the old rated 'severe' death events as less threatening than younger women. 相似文献

Two experiments demonstrated the way in which musicians and nonmusicians process realistic music encountered for the first time. A set of tunes whose members were related to each other by a number of specific musical relationships was constructed. In Experiment 1, subjects gave similarity judgments of all pairs of tunes, which were analyzed by the ADDTREE clustering program. Musicians and nonmusicians gave essentially equivalent results: Tunes with different rhythms were rated as being very dissimilar, whereas tunes identical except for being in a major versus a minor mode were rated as being highly similar. In Experiment 2, subjects learned to identify the tunes, and their errors formed a confusion matrix. The matrix was submitted to a clustering analysis. Results from the two experiments corresponded better for the nonmusicians than for the musicians. Musicians presumably exceed nonmusicians in the ability to categorize music in multiple ways, but even nonmusicians extract considerable information from newly heard music. 相似文献

We test the hypothesis that COVID-19 vaccine hesitancy is attributable to distrustful complacency—an interactive combination of low concern and low trust. Across two studies, 9,695 respondents from different parts of Britain reported their level of concern about COVID-19, trust in the UK government, and intention to accept or refuse the vaccine. Multilevel regression analysis, controlling for geographic area and relevant demographics, confirmed the predicted interactive effect of concern and trust. Across studies, respondents with both low trust and low concern were 10%–22% more vaccine hesitant than respondents with either high trust or high concern, and 26%–29% more hesitant than respondents with both high trust and high concern. Results hold equally among White, Black, and Muslim respondents, consistent with the view that regardless of mean-level differences, a common process underlies vaccine hesitancy, underlining the importance of tackling distrustful complacency both generally and specifically among unvaccinated individuals and populations. 相似文献
