INDIVIDUAL DIFFERENCES IN BASIC NORMAL INFORMATION PROCESSES

LSES在这一领域进行的研究旨在 在正常人中检查，从我们的比较中产生的基本认知问题 精神分裂症患者和正常人的认知功能。 这项研究的核心是调查的基本方面， 选择性注意-生物体如何选择性地对目标做出反应 当环境中的其他刺激引起竞争反应时，刺激。 我们完成了一系列实验的分析， 今年被接受出版的调查选择性关注 通过使用Stroop任务。使用随机刺激起始 我们展示了与早期发现不同的SOA 使用阻塞SOA，干扰中的奇异和不同峰， 便利化 这个项目中的其他实验关注选择性注意力 研究“负启动”。为了与LSES的兴趣保持一致， 这些实验测试了一个主要的假设， 认知老化的本质，老年人表现出 抑制性加工的缺陷理论上，这种赤字应该导致 负启动的减少。

The research being conducted in this area by the LSES is directed at examining in normals, basic cognitive issues arising from our 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. One series of experiments whose analyses we completed and whose results were accepted for publication this year investigated selective attention through the use of the Stroop task. Using randomized stimulus onset asynchronies (SOA) we demonstrated, as distinct from earlier findings using blocked SOAs, singular and different peaks in interference and facilitation. Other experiments in this project that focus on selective attention investigate "negative priming". In keeping with the LSES interest in normal aging these experiments testing a major hypothesis regarding the nature of cognitive aging according to which older adults demonstrate deficits in inhibitory processing. Such deficits should in theory lead to decreases in negative priming.
