Reid on the Perception of Visible Figure

Incomplete figure perception and invisible masking.

The Gollin test (measuring recognition thresholds for fragmented line drawings of everyday objects and animals) has traditionally been regarded as a test of incomplete figure perception or 'closure', though there is a debate about how such closure is achieved. Here, figural incompleteness is considered to be the result of masking, such that absence of contour elements of a fragmented figure is ...

The spatial scale of perceptual memory in ambiguous figure perception.

Ambiguous visual stimuli highlight the constructive nature of vision: perception alternates between two plausible interpretations of unchanging input. However, when a previously viewed ambiguous stimulus reappears, its earlier perception almost entirely determines the new interpretation; memory disambiguates the input. Here, we investigate the spatial properties of this perceptual memory, takin...

Visual Attention Model in Figure-Ground Reversal Perception

In figure-ground reversal perception for ambiguous figures, figure-ground relationship reverses depending on the position and the range of our attention. Our attention also changes depending on figural features. We propose a neural network model that explains a dynamic process concerning figure-ground perception and visual attention. Our model consists of two mechanisms: (i) one determines figu...
