It is shown that wrong inferences are drawn from samples because of failure to understand what constitutes a lot and because of failure to verify the existence of a lot in the practically useful sense. Time-tried methods of making valid inferences from samples without increased cost are pointed out. 相似文献

Never being fully able to be myself, I had slowly learned that the South could recognize but a part of a man, could accept
but a fragment of his personality, and all the rest—the best and deepest things of heart and mind—were tossed away in blind
ignorance and hate. 相似文献

Many questions about picture interpretation behavior remain to be answered One question relates to the psychological nature of such behavior and may be stated; What psychological processes are involved in drawing inferences from pictures? This study attempts to answer the question using a model of picture interpretation that consists of two interdependent forms of behavior: observation and inference drawing. The study focuses on the latter, which is further divided into productive and evaluative processes. These are accounted for by three constructs: operational facility, the ability to generalize concepts, and conceptual fluency. To test the model and related hypotheses, two pictorial tests of inference drawing and 19 reference tests were administered to 95 children aged 10 to 12 years, A factor analytic methodology was employed. 相似文献

This study compares the effects of three different evaluation conditions on the “continuing motivation” of grade school students in Iran and the U.S. In both cultural groups, the highest continuing motivation was shown by students in a self-evaluation condition followed, in order, by students in the peer comparison and teacher evaluation conditions. While the generalizability of evaluation effects is perhaps the most striking finding, it may he noted that these effects were to some extent modified by individual differences in achieving orientation and sex role. Also of interest were the effects of performance level on continuing motivation, In this case, higher levels of performance on the task were generally followed by greater continuing motivation. The theoretical implications of this and other findings were discussed in terms of Current achievement theory. 相似文献

学校改进中教师领导研究述评 总被引:1,自引:0,他引:1
在学校改进的研究中,教师领导已愈来愈成为重要的研究领域.目前学校改进中教师领导的研究集中于对行使领导力的教师--"领袖教师"的研究,围绕领袖教师在学校改进中的角色、能力、发展以及与他人的关系而展开.整体而言,现有的研究存在以下的特点:(1)领袖教师自身的专业发展是研究的核心;(2)整全式的研究策略;(3)领袖教师与情境的关系研究还较为缺乏. 相似文献

OBJECTIVE: Women with histories of childhood maltreatment (CM) have higher rates of physical health problems and greater medical utilization compared to women without abuse histories. This study examined whether current post-traumatic stress disorder (PTSD) symptoms mediate the relationship between CM and indicators of physical health and medical utilization in female veterans. METHOD: Respondents were 221 female veterans (56% of the potential sample), who received medical care from the San Diego VA Healthcare System during a 12-month period. Respondents provided self-report information about CM, PTSD symptoms, use of pain medication, and physical symptoms and functioning. Additional information about medical utilization was extracted from respondents' medical charts. Regression-based models were conducted to test whether PTSD symptoms mediate the relationships between CM and physical symptoms and between CM and medical utilization. RESULTS: Emotional abuse was associated with poorer role-physical functioning, increased bodily pain and greater odds of using pain medication in the past 6 months. Physical abuse was associated with poorer general health. Contrary to prediction, emotional neglect was associated with better role-physical functioning, and CM was not associated with increased healthcare utilization. PTSD was shown to mediate the relationship between emotional and physical abuse and health outcomes. CONCLUSIONS: PTSD, or psychopathology more generally, appears to be an important factor in the negative health impact of CM. Given that several empirically supported interventions are available for PTSD, there may be physical health benefits in early identification and treatment of psychopathology related to CM. 相似文献
