INDIVIDUAL DIFFERENCES IN BASIC NORMAL INFORMATION PROCESSES

这个项目研究了正常人的基本认知问题， 精神分裂症患者与正常人认知功能的比较 个体 这项研究的核心是调查基本的 选择性注意力的方面-生物体如何选择性地对一个 当环境中的其他刺激引起竞争时，目标刺激 应答今年的一个主要焦点是负启动-- 当一个物体被随后的忽视时的心理倾向 对该物体的反应要比对 新的对象。 我们开发并开始实施几个新的 实验程序，以进一步研究的参数， 并将其与其他认知特征联系起来， 工作记忆容量 此外，为了保持我们的兴趣， 我们完成了正常老化，并已接受在一个主要出版物上发表 杂志，一系列的实验，测试和投下非常强烈的怀疑， 根据该领域的一个中心假设， 表现出抑制性处理的缺陷。

This project examines in normals basic cognitive issues arising from comparisons of the cognitive functioning of schizophrenic and normal individuals. Central to this research is the investigation of basic aspects of selective attention --how organisms selectively respond to a target stimulus when other stimuli in the environment evoke competing responses. This year a major focus has been on negative priming --the psychological tendency when an object is ignored for subsequent responses to that object to be slower or less accurate than responses to new objects. We developed and began to implement several new experimental procedures to further investigate the parameters of the phenomena and to link it to other cognitive characteristics such as working memory capacity. In addition, in keeping with our interest in normal aging we completed, and had accepted for publication in a major journal, a series of experiments which tested and cast very strong doubt on a central hypothesis in the field according to which older adults demonstrate deficits in inhibitory processing.
