This article reviews the literature on dropout prevention for school-aged children. A review of dropout prevention programs identified in the literature highlights methodological concerns, with a discussion of design, sampling, statistical analysis, and implementation issues. The interventions employed with greatest frequency in the studies reviewed emphasized academic enhancement, psychosocial skill development, mentoring, and parent/teacher behavior management training. Programs that were academically oriented or those that were multi-component programs emerged with the most promising empirical base. However, at the present time, there is a lack of consistent and persuasive outcome evidence that meet Kratochwill and Stoiber's [Sch. Psychol. Q. 15 (2001) 233] criteria for empirically supported interventions. This deficiency leads to the conclusion that there is no one particular best practice or beneficial treatment currently available to address the problem of school dropout even though a number of intervention programs appear to hold promise. Implications for school psychologists include both practice and research applications.  相似文献

Spontaneous speech samples were obtained from 19 institutionalized mongoloids and from 19 normally intelligent individuals. All subjects were evaluated by a panel of speech pathologists to be nonstutterers. Subjects' speech samples were analyzed to determine (a) frequency of occurance of seven disfluency categories per 100 words spoken, (b) the proportion of each category in the total number of disfluencies. Statistically significant differences indicated that the mongoloids were more disfluent both absolutely and relatively, on categories that have been regarded as most typical to speech of stutterers. Interpretations were made to reflect on factors which may enhance the high prevalence of stuttering among Down's Syndrome patients.  相似文献

Culture can moderate which variables most influence subjective well-being (SWB). Because religion can be conceptualized as culture, religious differences can be considered cultural differences. However, there have been few studies comparing how different religious groups evaluate SWB at any given time. This study is among the first to investigate this issue. The present study compared Buddhists, Taoists, Christians, and atheists. In addition to demographic items, 451 Chinese adults completed Chinese version of the Socially Oriented Cultural Conception of SWB Scale. Religious belief was distributed as follows: 10 % Christian, 20 % Buddhist, 25 % Taoist, and 43 % atheists. As predicted, the socially oriented cultural conception of SWB was found to be highest among Buddhists, followed in order by Taoists, atheists, and Christians. It was concluded that the various religious groups achieved SWB in different ways.  相似文献

Path integration and cognitive mapping are two of the most important mechanisms for navigation. Path integration is a primitive navigation system which computes a homing vector based on an animal’s self-motion estimation, while cognitive map is an advanced spatial representation containing richer spatial information about the environment that is persistent and can be used to guide flexible navigation to multiple locations. Most theories of navigation conceptualize them as two distinctive, independent mechanisms, although the path integration system may provide useful information for the integration of cognitive maps. This paper demonstrates a fundamentally different scenario, where a cognitive map is constructed in three simple steps by assembling multiple path integrators and extending their basic features. The fact that a collection of path integration systems can be turned into a cognitive map suggests the possibility that cognitive maps may have evolved directly from the path integration system.  相似文献
