This longitudinal study examined associations between three after-school program quality features (positive staff–child relations, available activities, programming flexibility) and child developmental outcomes (reading and math grades, work habits, and social skills with peers) in Grade 2 and then Grade 3. Participants (n = 120 in Grade 2, n = 91 in Grade 3) attended after-school programs more than 4 days per week, on average. Controlling for child and family background factors and children’s prior functioning on the developmental outcomes, positive staff–child relations in the programs were positively associated with children’s reading grades in both Grades 2 and 3, and math grades in Grade 2. Positive staff–child relations also were positively associated with social skills in Grade 2, for boys only. The availability of a diverse array of age-appropriate activities at the programs was positively associated with children’s math grades and classroom work habits in Grade 3. Programming flexibility (child choice of activities) was not associated with child outcomes. 相似文献

Women with a personal or family history of breast or ovarian cancer are increasingly presenting for genetic cancer risk assessment (GCRA). To explore the personal and family impact of GCRA, four focus groups were conducted of women seen for risk assessment. Participants were 22 primarily non-Latina White women with a personal or family history of breast or ovarian cancer. Analysis of the data identified new themes related to balancing time to assimilate risk information with the need to make timely healthcare decisions, physicians’ lack of sufficient genetic knowledge, and concern for daughters regardless of the daughters’ age. Other themes related to protecting others, knowledge as empowerment, reassessing personal attribution of cancer risk, managing uncertainty, reappraising body image, and experiencing divergent family responses to communication of cancer risk and healthcare decisions. Understanding the personal and family impact of GCRA may enable genetics professionals to tailor their counseling efforts to better meet the needs of these women. Additional research is needed to extend these findings and identify interventions to support positive outcomes of GCRA. 相似文献

It is remarkably difficult for people with obesity to maintain a new lower weight following weight loss. The aim of the present study was to examine the immediate and longer-term effects of a new cognitive behavioural treatment that was explicitly designed to minimise this post-treatment weight regain. One hundred and fifty female participants with obesity were randomized to the new treatment, behaviour therapy (the leading alternative psychological treatment) or guided self-help (a minimal intervention). Both of the main treatments resulted in an average weight loss of about ten percent of initial weight whereas weight loss was more modest with guided self-help. The participants were subsequently followed-up for three years post-treatment. The great majority regained almost all the weight that they had lost with the new treatment being no better than the behavioural treatment in preventing weight regain. These findings lend further support to the notion that obesity is resistant to psychological methods of treatment, if anything other than a short-term perspective is taken. It is suggested that it is ethically questionable to claim that psychological treatments for obesity “work” in the absence of data on their longer-term effects. 相似文献

Repetitive and invariant behavior is a diagnostic feature of autism. We implemented a lag reinforcement schedule to increase response diversity for 6 participants with autism aged 6 to 10 years, 4 of whom also received prompting plus additional training. These procedures appeared to increase the variety of building-block structures, demonstrating that an intervention that includes differential reinforcement can increase response diversity for children with an autism spectrum disorder. 相似文献

Visual cues are known to be used by numerous animal taxa to gather information on quality and localisation of resources. Because
environmental lighting can interfere with the spectral features of visual cues, the specific characteristics of the colour
signals that promote forager decision and learning are still not known in the majority of insects (excepted in bees). We analysed
the effect of previous experience on the use of visual information by the wasp Venturia canescens, a parasitoid of pyralidae, in the context of host searching. These parasitoids search for hosts concealed in several fruit
species, so visual cues from the host microhabitat could play a key role in host finding. We also investigated the type of
visual cues on which wasps based their decision. We tested whether wasps are able to associate an achromatic cue (brightness)
or a chromatic one (hue, i.e. dominant wavelength and/or chroma) with the presence of hosts. Our results show that in the
context of host foraging, chromatic cues are more reliable than brightness in achieving the associative learning process.
Therefore, understanding the behavioural ecology of foraging should make use of the knowledge about the visual information
used. 相似文献

Direct and Indirect Aggression: Relationships as Social Context 总被引:1,自引:0,他引:1
The studies reported in this paper examined the effect of social context—target gender and target relationship—on reports of direct and indirect aggression. In Study 1, participants completed the Richardson Conflict Response Questionnaire (RCRQ; Richardson & Green, 2003 ), which measured their direct and indirect aggression behavior in response to anger. Participants also selected a relationship partner to complete the RCRQ with reference to their own (i.e., participants') behavior. In Study 2, participants completed the RCRQ with reference to their behavior in response to anger with a romantic partner, a same-sex friend, and an opposite-sex friend. In both studies, relationship with aggression target was an important determinant of aggression, with more direct aggression occurring in romantic relationships, and more indirect aggression occurring in friendship relationships. 相似文献
