Flicker‐defined form stimuli are minimally affected by centre‐surround lateral contrast interactions

ConclusionFDF stimuli necessarily have both flickering target and background. Our results suggest that visual field defects outside the target are unlikely to markedly influence the detection and perception of the FDF stimulus. Nevertheless, mild surround suppression of contrast arises for FDF stimuli, hence interactions between the background and the target area may influence FDF results in conditions that alter centre‐surround perceptual effects.
