Two experiments were conducted to study the perceptual facilitation and inhibition that occurs between foveal and parafoveal or peripheral regions of the eye. Experiment 1 used a Stroop task to compare color detection latencies of foveal and parafoveal targets. The target and distractor components of the Stroop stimuli were separated and presented with varied stimulus onset asynchronies. Experiment 2 used a Stroop-like task to replicate and extend the findings into the visual periphery. Subjects were found to process foveally presented distractor information while attending to targets presented in parafoveal or peripheral regions of the eye. Distractor information that was incompatible was suppressed while compatible information was used to facilitate target processing. When the targets were presented foveally along with the distractor information, subjects appeared to automatically process the distractor information. The findings are discussed within the framework of past studies that presented subjects with competing tasks across retinal location. The implications of these findings to a two-process theory of attention are also considered.
进行了两项实验，以研究眼睛中央凹与中央凹旁或周边区域之间发生的知觉促进和抑制作用。实验1使用斯特鲁普任务来比较中央凹和中央凹旁目标的颜色检测潜伏期。将斯特鲁普刺激的目标和干扰成分分离，并以不同的刺激起始异步呈现。实验2使用类似斯特鲁普的任务将这些发现复制并扩展到视觉周边区域。研究发现，当关注眼睛中央凹旁或周边区域呈现的目标时，受试者会处理中央凹呈现的干扰信息。不相容的干扰信息被抑制，而相容的信息则用于促进目标处理。当目标与干扰信息一起在中央凹呈现时，受试者似乎会自动处理干扰信息。在过去让受试者在视网膜不同位置执行竞争任务的研究框架内讨论了这些发现。还考虑了这些发现对双加工注意理论的意义。
