HARRIS Neural Systems Group, Department of Psychology, Ridley Building, University of Newcastle-upon-Tyne, Newcastle, NE1 7RU, UK Received 3 September 1999; revised 28 January 2000; accepted 28 March 2000 Abstract —A peripherally presented target embedded in dynamic texture perceptually disappears (or ‘ lls-in’) after around 10 s of steady xation. This phenomenon was investigated for a target containing moving dots. The effects of manipulating the coherence of the motion within the target and the density of dots across the whole screen were explored. Coherence thresholds for the detection of a target at different dot densities were recorded for comparison. Fading occurred faster as either motion coherence or dot density was reduced. Coherence thresholds for target detection were unaffected by manipulations of dot density. There appeared to be no relationship between the stimulus exposure time needed for fading and the coherence threshold for detection of a target. The results suggest that the time taken for a target to fade is not a
