Abstract

Temporal interactions between spatially separated visual stimuli wereinvestigated in human observers. Subjects had to judge whether briefly presented targets consisted of a single or a double Bash. Simultaneous presentation of unattended single or double flash distracters impaired performance if target and distracter followed different time courses, confirming previous findings. This interference occurred only whentargets had high luminance contrast or were isoluminant and when distracters had high or low luminance contrast, but not when targets had low luminance contrast or when distracters were isoluminant. Low luminance contrast distracters strongly influenced high luminance contrast targets but not vice versa. These results suggest that (i) information about the precise temporal structure of stimuli is conveyed preferentially by the luminance-sensitive magnocellular system; and (ii) that this information influences judgements on the temporal patterning of signals transmitted by the colour-sensitive parvocellular system.
