摘要: 实验研究了中央和外周提示信号对辨别朝向的任务(局部几何性质检测)和辨别有或无的任务(拓扑性质检测)的影响。结果表明,对于两种提示信号,在提示有效和提示无效条件下,辨别有或无比辨别朝向具有较短的反应时和较低的错误报告率;辨别朝向的RT和错误报告率都受提示信号的影响;而对于辨别有或无的任务,只有RT受提示信号的影响;提示信号对辨别朝向的影响比辨别有或无的影响大。本实验排除了对Han和Chen的实验的可能的光通量解释,并为提示信号对不同几何性质检测的不同影响提供了进一步的实验证据。

Abstract: The effects of central and peripheral pre-cues on the detection of orientation and presence-absence was studied. The results indicated that the detection of presence-absence showed shorter RTs and lower error rates than that of orientation in both valid and invalid conditions for central and peripheral cues.Pre-cues affected the detection of orientation in terms of both RT and error rate,but they affected the detection of presence-absence only in terms of RT.The pre-cue effects on the detection of orientation were stronger than that of presence-absence.The present results did not support the possible explanation based on the difference of luminous flux of Han and Chen's[4] experiment,and gave more evidences for the differential effects of pre-cues on the detection of different geometric properties.
