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-abserece 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 experiment,and gave more evidences for the different effects of pre-cues on the detection of different geometric properties. Key words Attention, Precue, Local geometric property, Topological property.
