Exam 4: Recognizing Visual Objects

In the context of neural basis of perceptual interpolation, von der Heydt et al. (1984) conducted experiments with monkeys to record the responses of single neurons in area V2. The figure shows four stimuli and four response patterns for neurons in area V2. These recordings suggest that there is a neural basis for the representation of:

Question 3

Correct Answer:

Verified

Perceptual organization involves the following steps:
A. Represent edges-abrupt, elongated changes in brightness and/or color.
B. Represent uniform regions bounded by edges.
C. Divide these regions into figure and ground, and assign border ownership.
D. Group together regions that have similar properties (e.g., color). Groups consisting of "figure" regions are represented as candidate objects; other groups of regions are represented as background.
E. Fill in missing edges and surfaces-that is, edges and surfaces that are partly occluded-to obtain more complete representations of candidate objects.
