While much of the previous research has examined the influence of consumers' social and economic states on conspicuous consumption, little attention has been paid to the potential role that consumers' decision-making tendency plays. This study investigates whether, how, and when maximizing, as a type of decision-making tendency (both dispositional and situationally primed), influences subsequent decisions regarding conspicuous consumption. Four studies were conducted, revealing that maximizing consumers are more likely to engage in conspicuous consumption than non-maximizing consumers (Studies 1 and 2). The need for status serves as the underlying mechanism behind this behavior (Study 3). In addition, the observed effect holds only when the situation is public but disappears when it is private (Study 4). As one of the first investigations into the effect that maximizing has on a type of consumption, these findings offer valuable contributions to both theory and practice. 相似文献
Computer assisted instruction (CAI) was used for improving the efficiency of simple addition (single-digit without carrying) computation in three children with mental retardation. The training program, conducted on a portable personal computer, consisted of demonstrations and repetitive practices on simple addition presented in a vertical format. A number of behavioral instruction techniques such as direct feedback, corrective demonstration, verbal association, and token reinforcement were also included. To evaluate the effects of the CAI package, a multiple-baseline across subjects design with followup was employed. Results showed that performances of children improved with training and were maintained at 1-week, 4-week, and 12-week followups. Generalization of the learned skills was evident when children were assessed on a paper-and-pencil addition test in a vertical format. The skills were also transferable, with initial prompting, to a computerized addition test in a horizontal format. These findings reaffirmed the applicability of CAI and behavioral techniques for teaching math skills to children with mental retardation. 相似文献
Children with autism were taught spontaneous requests through a time delay procedure. Unlike previous research, which usually employed food as the target stimuli to be requested, the present study used toy pieces from multi-component toys. The procedure involved presenting a child with the target stimulus, with the trainer prompting the child by immediately modeling the request response. When the response was imitated without error, prompting was delayed with the time interval gradually being increased over trials. A spontaneous or imitated response was reinforced by giving the child the requested object. As the stimulus/model interval increased, children with autism were expected to initiate the request by themselves prior to the prompt. The efficacy of the time delay procedure was assessed using a multiple baseline across subject design with three Chinese boys with autism. Results showed that the three children acquired a 100% performance within five to nine sessions of training and the skill was maintained at the one-month and three-month followups. Furthermore, the learned response transferred to various conditions when tested across setting, person, toy, and food items. These results suggest that toys, the multi-component ones in particular, served well as reinforcers for language training. Furthermore these findings confirmed the practical utility of the time delay procedure for promoting spontaneous communication skills in children with autism. 相似文献
对美国食品药品监督管理局(Food and Drug Administration,FDA)儿童药物临床试验的规范化进行界定,发现我国面临儿童用药方面存在安全隐患、儿童药物临床试验存在需求缺口、儿童药物临床试验审查不够规范等现实困境,引发规范儿童药物临床试验的关键性思考。借鉴FDA对儿童药物临床试验的规范化实践,总结FDA儿童药物临床试验相关法案、临床试验指南文件以及对伦理审查委员会的监管措施,得出完善儿童药物临床试验专门法规和指南、加强相关伦理委员会监管和指导、规范儿童药物临床试验伦理审查、加大儿童受试者保护力度等对我国的启示。
