In this study, based on the Feature Integration Theory of Attention by Treisman and Gelade, the ability of the schizophrenic child to recognize the task relevance of, and engage in, serial and parallel modes of visual search is examined. Schizophrenic children were as competent as MA-matched control children in their use of a parallel visual search strategy and a serial visual search strategy, and in their recognition of the situations under which each is the optimal strategy; they had a significantly greater start-up time than the MA-matched controls in the initiation of their search strategies, greater than would be predicted on the basis of merely a motor delay in button pushing. Results suggest that the schizophrenic individual does not have a specific information processing deficit, but rather a global deficit in time to initiate the operation of any information processing strategy, be it an automatic strategy or an attention demanding strategy.

本研究以注意的特征整合理论为基础， 由特雷斯曼和杰拉德，精神分裂症儿童的能力， 认识到任务的相关性，并参与，串行和并行 视觉搜索的模式进行了研究。 精神分裂症儿童 与MA匹配的对照组儿童一样， 并行视觉搜索策略和串行视觉搜索策略 战略，并认识到 每一种都是最优策略， 启动时间比MA匹配的对照组 他们的搜索策略，大于预测的 这仅仅是因为按下按钮时的电机延迟。 结果表明 精神分裂症患者并没有一个特定的 信息处理不足，而是全球时间不足 为了启动任何信息处理策略的操作， 无论是自动策略还是需要注意力的策略。
