Youth violence in the United States has emerged as a major concern for communities, policymakers and community researchers. This paper reports on the efforts of a child mental health clinic to build a community consensus around addressing violence that affects youth and all members of the community. We describe and give case examples regarding our approach to acquiring the perspectives of the community, particularly that of youth, discuss key themes and implications that emerged from our work, and offer preliminary recommendations for designing a youth violence prevention initiative in a disenfranchised community.

Two experiments examined the effects of memory set size and information structure on learning and retention. Participants learned 48 (small set) or 144 (large set) facts about individuals, and were tested over 48 facts. The test facts included either 4 facts about 12 individuals (12-person condition) or 12 facts about 4 individuals (4-person condition). During learning, there was an advantage for the small-set group in the 4-person condition, but a disadvantage in the 12-person condition. During testing, there was an advantage for the 4-person condition relative to the 12-person condition for the small-set group, even when the conditions were equated in terms of name exposure. The results support a mental model account of memory representation and retrieval.  相似文献

Line bisection is an established clinical task used to diagnose visuospatial neglect. To date, few studies have considered the extent to which age and sex as background variables contribute to bisection performance. Both variables affect the neural substrates underlying cognitive processes and hence the behavioural performance of bisection. The purpose of this study was to examine the effects of age and sex on normal bisection performance, using three different line lengths to elucidate the influence of these potential contributing factors. Seventy men and 70 women, divided equally into seven age-cohorts between 14 and 80 years, bisected lines. Results indicated clear age- and sex-related differences both in the magnitude and direction of bisection deviations across the three line lengths. Differences are discussed in terms of neural changes across the adult lifespan including hemispheric differences and hormonally mediated changes.  相似文献

The conceptual basis for many effective language-training programs are based on Skinner's (1957) analysis of verbal behavior. Skinner described several elementary verbal operants including mands, tacts, intraverbals, and echoics. According to Skinner, responses that are the same topography may actually be functionally independent. Previous research has supported Skinner's assertion of functional independence (e.g., Hall & Sundberg, 1987; Lamarre & Holland, 1985), and some research has suggested that specific programming must be incorporated to achieve generalization across verbal operants (e.g., Sigafoos, Reichle, & Doss, 1990). The present study provides further analysis of the independence of verbal operants when teaching language to children with autism and other developmental disabilities. In the current study, 3 participants' vocal responses were first assessed as mands or tacts. Generalization for each verbal operant across alternate conditions was then assessed and subsequent training provided as needed. Results indicated that generalization across verbal operants occurred across some, but not all, vocal responses. These results are discussed relative to the functional independence of verbal operants as described by Skinner.  相似文献

Although experimental analysis methodologies have been useful for identifying the function of a wide variety of target behaviors (e.g., Iwata, Dorsey, Slifer, Bauman, & Richman, 1982/1994), only recently have such procedures been applied to verbal operants (Lerman et al., 2005). In the current study, we conducted a systematic replication of the methodology developed by Lerman et al. Participants were 4 children who had been diagnosed with developmental disabilities and who engaged in limited vocal behavior. The function of vocal behavior was assessed by exposing target vocal responses to experimental analyses. Results showed that experimental analyses were generally useful for identifying the functions of vocal behavior across all participants.  相似文献

In 2 experiments, the efficacy of motor imagery for learning to type number sequences was examined. Adults practiced typing 4-digit numbers. Then, during subsequent training, they either typed in the same or a different location, imagined typing, merely looked at each number, or performed an irrelevant task. Repetition priming (faster responses for old relative to new numbers) was observed on an immediate test and after a 3-month delay for participants who imagined typing. Improvement across the delay in typing old and new numbers was found for the imagined and actual typing conditions but not for the other conditions. The findings suggest that imagery can be used to acquire and retain representations of sequences and to improve general typing skill.  相似文献

The place and importance of counseling in State Employment Services has, in many instances, not been recognized as a necessary function of the United States Training and Employment Service (USTES) by some local office managers as well as administrators. After discussing this matter with the counselors in the Halsted office, the following article was written not to justify the existence of counseling but hopefully to show its importance.  相似文献

The purpose of the study was to examine the hypothesis that parents’ psychological well-being can be affected by a child’s illness and their social situations. In this study, we discuss the roles of coping, social support and situational context related to stress. These factors cannot only affect stress levels but can also influence whether the individual adopts a certain type of coping style for stressful events. Parental stress, coping styles and social support were compared between groups of parents of Hepatitis B virus (HBV) carrier children or healthy children. Results showed that parents of affected children were significantly more stressed and psychologically at risk, and tended to mobilize personal resources and to rely more on themselves to solve stressful life events. They also sought help from social resources more often than did parents of healthy children. Parents of healthy children had a higher number of close friends and relatives available to them. Ninety Chinese parents and their HBV or healthy children participated in this study. These families were all living in the city of Guangzhou, China.  相似文献
