mask displayed integrationAbstract
Shapes can be displayed as parts but perceived as a whole through feedforward and feedback mechanisms in the visual system, though the exact spatiotemporal relationships for this process are still unclear.
Our experiments examined the integration of letter fragments that were displayed as a rapid sequence.
We examined the effects of timing and masking on integration, hypothesizing that increasing the timing interval between frames would impair recognition by disrupting contour linkage.
We further used different mask types, a full-field pattern mask and a smaller strip mask, to examine the effects of global vs local masking on integration.
We found that varying mask types and contrast produced a greater decline in recognition than was found when persistence or mask density was manipulated.
The study supports prior work on letter recognition and provides greater insight into the spatiotemporal factors that contribute to the identification of shapes.
