Responding to feature or location: a re-examination of inhibition of return and facilitation of return.
It was found [Vision Res. 36 (1996) 2125] that reaction times for repeated targets were longer in detection and location discrimination tasks (inhibition of return; IOR) and shorter in color and orientation discrimination tasks (facilitation of return; FOR). The present experiment, using a more detailed analysis, shows that both IOR and FOR can be found in the discrimination tasks. Overall, the results are inconsistent with the notion that IOR and FOR effects reside in separate visual pathways. Rather, the results are accounted for by repetition priming and IOR that occur with specific combinations of target features and task demands.
