Abstract

Research pertaining to reactive attachment disorder (RAD) is reviewed to clarify existing knowledge about the diagnosis and to identify avenues for enhancing the lives of afflicted individuals and their immediate family members. An overview of literature pertaining to the diagnosis is provided initially. Family experiences associated with the presence of children with significant attachment problems are subsequently examined. The focus is on interrelationships among RAD behavioral characteristics and associated challenges to parents and siblings. Finally, relevant literature derived from different subareas within psychology and from related fields outside the discipline is organized and integrated with the goal of providing direction for future research and attempts to support families.  相似文献

How might we balance assistance and penalties to intelligent tutors and educational games that increase learning and interest? We created two versions of an educational game for learning policy argumentation called Policy World. The game (only) version provided minimal feedback and penalized students for errors whereas the game+tutor version provided additional step-level teaching feedback and immediate error correction. A total of 105 university students played either the game or game+tutor version of Policy World in a randomized, controlled, two-group, between-subjects experiment, during which we measured students’ problem-solving abilities, interest in the game, self-reported competence, and pre- and posttest performance. The game+tutor version increased learning of policy analysis skills and self-reported competence. A path analysis supported the claim that greater assistance helped students to learn analysis better, which increased their feelings of competence, which increased their interest in the game. Log data of student behavior showed that debate performance improved only for students who had sufficiently mastered analysis. This study shows that we can design interesting and effective games to teach policy argumentation and how increasing tutoring and reducing penalties in educational games can increase learning without sacrificing interest.  相似文献

Studies have shown that young children with autism are not impaired on prefrontal tasks relative to what would be expected for their mental age, raising questions about the executive dysfunction hypothesis of autism. These studies did not include ventromedial prefrontal tasks, however. The present study examined whether young children with autism spectrum disorder (ASD) are impaired on ventromedial prefrontal tasks, and whether performance on such tasks is correlated with a core autism symptom, joint attention ability. Seventy-two 3- to 4-year-old children with ASD, 34 3- to 4-year-old developmentally delayed children, and 39 12- to 46-month-old typically developing children, matched on mental age, were administered ventromedial and dorsolateral prefrontal tasks and joint attention tasks. Children with ASD performed similarly to comparison groups on all executive function tasks, indicating that at this early age, there is no autism-specific pattern of executive dysfunction. Ventromedial, but not dorsolateral, prefrontal task performance was strongly correlated with joint attention ability, however. The ventromedial prefrontal cortex is hypothesized to play a role in the development of joint attention and possibly some aspects of the autistic syndrome.  相似文献

Norms, reliabilities, and validities for the five scales of an instrument designed to measure Bruner’s model are presented. In testing the instrument on a random sample of men and women, it was found that persons of both sexes emphasized knowledge of society, human condition, natural world, past, and artistic heritage in that order. It is suggested that the Educational Values Inventory may be able to provide useful information to educational planners when developing institutional goals.  相似文献
