The present study investigated the effects of weekly dog visits on depression scores, mood, and social interaction in elderly individuals living in a nursing home. Five elderly residents participated in baseline assessments for 4–8 weeks and then received weekly dog visits for 6 weeks. Assessments, consisting of weekly observations of social interaction and paper and pencil measures of mood and depression, continued during the dog visits. The effect of dog visits was evaluated in a multiple baseline across participants design. Dog visits did not improve depression scores, mood (with the exception of one resident), or social interaction (with the exception of one resident). Residents did interact with the dog during the visits, however, and reported that they enjoyed the visits. These results show that dog visits do not always have therapeutic effects and suggest the need for further research in the area before the beneficial effects of dog visits can be substantiated.

Reduction in physical activity is considered a major contributor to weight problems. Increasingly, people are expending less
energy in household chores but joining fitness clubs. Do people perceive ordinary daily activities to expend less energy than
exercise activities using similar amounts of calories? In the present study college students were asked to evaluate the calorie
expenditure of 30 physical activities (i.e., exercises and household tasks). The household tasks were matched (in terms of
caloric expenditure) to at least one exercise activity. When participants rated both exercise and daily activities, it appears
that they focused on rate of caloric expenditure rather than type of activity (i.e., household task or exercise). In Study
2, college students evaluated the energy expenditure of light/leisure, moderate, and intense exercise. This emphasis concerning
the benefit of intense physical activity was observed once again. College students appear to have assimilated the belief that
intense physical activity expends more energy than longer sessions of lower intensity physical activity using similar amounts
of calories. Perhaps one reason why people are not physically active is that they believe physical activities must be intense
to be of benefit. At the same time they are automatizing household chores and, thus, become less active overall. 相似文献

How might people best persuade themselves to engage in beneficial activities, such as dieting, exercise, and studying? One strategy is to think about actions. Another strategy is to think about reasons. In previous research, students who were directed to think about actions increased their study intentions more than did students who were directed to think about reasons. The present experiment tested whether thinking about actions was effective because of idea generation (coming up with the thoughts) or because of mental simulation (imagining the scenarios). In immediate and delayed measures, directed thinking about actions (but not reasons) proved generally more effective when students focused on mental simulation than when they focused on idea generation. Theoretical and applied implications are discussed. 相似文献

According to the Group Value Model, group authorities and procedures communicate symbolic information to people about whether the group values or respects them. Employees for a concrete construction company completed a questionnaire about their work experiences in either English or Spanish. Among employees who identified more strongly with the concrete construction company, the quality of supervisor treatment predicted employees' feelings of respect and personal self-efficacy. Further, for employees who identified with the company, feeling respected by their colleagues mediated the relationship between fair treatment by a single supervisor and self-efficacy. Even when the working context encourages short term and instrumental goals, these results suggest that employees who identify with the company still care about fair treatment because of the self-relevant information it communicates to them. 相似文献
