abstract
- The purpose of the two experiments reported here was to replicate previous research (Thomson, 1983) which suggests that visual information useful in the control of movement persists for up to 8 s after visual occlusion. Contrary to other findings (Thomson, 1980, 1983), little evidence was found for an 8-s visual representation of the environmental layout, indicating there is no substitute for continuous visual information in the control of movement. Methodological and statistical problems with Thomson's work are discussed.
