We review the recently published report by the Committee on the Prevention of Reading Difficulties in Young Children from a behavior analytic perspective. The authors prescribe what children should learn to be successful readers based on the correlates of reading and the developmental progression of reading errors. The report offers no discussion of theoretical models that can be used by teachers and parents to reform reading instruction or specific procedures that have been shown to be effective at promoting various reading skills. We discuss these omissions in terms of the level of research included in the review, the authors' structural approach to synthesizing this research, and the constructivist orientation common to many early childhood educators. The paper concludes by identifying models and strategies from the behavior analysis literature that can be used to guide instruction and offers a modest suggestion for future reviews of reading research.  相似文献

The author examines two significant issues, the adjudication of evidence and the architecture of instruction in the context of research on beginning reading. In particular, he reflects on his participation as a member of the National Research Council's committee that published the recent report entitled Preventing Reading Difficulties in Young Children (1998). The National Academy of Sciences panel of experts process is contrasted with a more explicit process for codifying scientific evidence and including quantitative experimental research as the primary source of evidence. In addition, the author argues for the importance of attending to the architecture of instruction in beginning reading.  相似文献

While psychologists have been active faculty members in medical schools for over 85 years, they lacked organization on the national level until 1981. This history traces the background of psychology's involvement in medical schools, landmark events that affected the discipline, and progress since formal organization has occurred.

Children of HIV-infected mothers have more psychosocial adjustment difficulties than do those of noninfected mothers. In this study, child psychosocial adjustment in children of HIV-infected women is examined across the three stages of HIV-infected: asymptomatic, symptomatic and AIDS. Participants were 99 HIV-infected women and 148 noninfected women. Children were not identified as being HIV infected. Mother and child reports of behavioral difficulties are compared, and competing hypotheses about mother report of child behavior difficulties are tested. Results indicate an ascending linear trend for child report of internalizing and externalizing difficulties from the noninfected stage through increasingly severe stages of HIV-infection. According to mother report, child externalizing and internalizing difficulties are nonlinear, as mothers report an increase through the infected symptomatic stage, then a decrease in the AIDS stage. Implications for assessment, prevention and intervention in families with maternal HIV infection are discussed.  相似文献

This paper describes the development of a coding instrument to classify college students' strategies for preventing HIV infection, and examines the association of distinct strategies with social cognitive and behavioral measures related to safer sexual behavior. This instrument classifies each strategy into both a content domain (e.g., using condoms, remaining abstinent, limiting sexual partners), and 3 distinct dimensions: commitment, specificity, and effectiveness. We examine the reliability and validity of this instrument by showing the discriminative associations of each dimension with social cognitive and behavioral measures, and demonstrate the differential importance of distinct dimensions in predicting behavior in different content domains. Discussion focuses on the importance of tailoring HIV prevention messages to change strategy dimensions in order to maximize behavior change.  相似文献

This study assessed the performance of the PC-PTSD in diagnosing postdeployment posttraumatic stress disorder (PTSD) in a cohort of Air Force Medical Services personnel (N = 18,530). The prevalence of PTSD in the cohort was 5.18% based on medical record data. The area under the receiver operating characteristic curve was 0.69, indicating poor classification accuracy. Sensitivity was 47.55%, specificity was 90.68%, positive predictive value was 21.79%, and negative predictive value was 96.94%. The positive and negative likelihood ratios were 5.10 and 0.58, respectively. Several risk factors were found to be associated with a diagnosis of postdeployment PTSD: being a nurse, being enlisted in the medical service career field, being enlisted in the mental health service career field, those over age 30, being a member of the Active Duty service component, and having one’s first deployment be to Iraq. Being an officer was found to be a protective characteristic. These factors could potentially improve screening for PTSD among Air Force healthcare personnel.  相似文献

Progressive taxation and the subjective well-being of nations   总被引:1,自引:0,他引:1  
Using data from the Gallup World Poll, we examined whether progressive taxation is associated with increased levels of subjective well-being. Consistent with Rawls's theory of justice, our results showed that progressive taxation was positively associated with the subjective well-being of nations. However, the overall tax rate and government spending were not associated with the subjective well-being of nations. Furthermore, controlling for the wealth of nations and income inequality, we found that respondents living in a nation with more-progressive taxation evaluated their lives as closer to the best possible life and reported having more positive and less negative daily experiences than did respondents living in a nation with less-progressive taxation. Finally, we found that the association between more-progressive taxation and higher levels of subjective well-being was mediated by citizens' satisfaction with public goods, such as education and public transportation.  相似文献
