Concern about the exposure of children and adolescents to occupational and environmental hazards has increased, and so has the need to develop testing methods that can adequately assess the effects of exposure in children. A computerized testing system, the Behavioral Assessment and Research System (BARS), was successfully modified to test both younger populations and populations which do not speak English, the original language of the battery. These adaptations were modifications of the existing features of the BARS system which was designed to assess the broadest possible audience: simple language instructions broken down into basic concepts (step-by-step training with competency testing at each instruction step); a token dispenser along with a "smiling face" stimulus that reinforced appropriate performance; and adjustable parameter settings (e.g., number of trials, difficulty). Data from four groups demonstrate the feasibility of using BARS with children as young as preschool age and for non-English speaking children.
人们对儿童和青少年接触职业及环境危害的担忧日益增加，因此开发能够充分评估儿童接触危害影响的测试方法的需求也随之增加。一种计算机化测试系统——行为评估与研究系统（BARS）——已成功修改，以测试较年轻人群以及不讲该测试系统原始语言（英语）的人群。这些调整是对BARS系统现有功能的修改，该系统旨在评估尽可能广泛的受众群体：将简单语言指令分解为基本概念（在每个指令步骤进行能力测试的逐步培训）；一个代币发放器以及一个强化正确表现的“笑脸”刺激物；还有可调整的参数设置（例如，试验次数、难度）。来自四组的数据证明了将BARS用于学龄前儿童以及非英语儿童的可行性。
