Substantial research has shown that positive psychological interventions (PPIs) have beneficial effects on well-being. This article evaluates whether PPIs would be effective for everyone, across different cultures. It starts by reviewing the effectiveness of PPIs among the general population, as well as their effectiveness in ameliorating depressive symptoms and increasing well-being among clinical samples. Though generally beneficial, PPIs however, may not be equally effective across cultures. We present evidence showing that certain types of PPIs may be less effective for Asians than those from Western cultures. Next, the article examines whether prosocial behavior may be a PPI that is universally beneficial and the possible explanations for its widespread benefits. Finally, we proceed to propose how the current repertoire of PPIs may be expanded to include new types that may be more suited for those in collectivistic cultures. Synthesizing across these areas, this article concludes with suggestions on how PPIs can be adapted for use across cultures, as well as future directions for the field of PPIs.
The effect of force requirements on response effort was examined using outbred (CD-1) mice trained to press a disk with their snout. Lateral peak forces greater than 2 g were defined as threshold responses (i.e., all measured responses). Different force requirements were used to define criterion responses (a subclass of threshold responses) that exceeded the requirement. The reinforcer was sweetened, condensed milk, and it was delivered upon response termination. All mice were exposed to two ascending series of criterion force requirements (2, 4, 8, 16, and 32 g). Increasing the force requirement decreased criterion response rates, but increased threshold response rates. The time-integral of force (area under the force-time curve for individual responses, which is proportional to energy expenditure for each response) increased with the increase in the force requirement. These results conflict with the hypothesis that higher force requirements have aversive qualities and suggest that increased force requirements are more analogous to intermittent schedules of reinforcement. These data suggest that estimations of effort or energy expenditure should be measured independently of the force requirement. Individual differences in responding were found for the CD-1 outbred stock. 相似文献
