Local motion detector responses to a rigidly moving shape:
A) All correspond to the direction and speed of the shape regardless of local orientation
B) Vary in direction according to local contour orientation
C) Vary in direction and speed according to local contour orientation
D) Vary in speed according to local contour orientation

Question

Quizplus · Accepted Answer

Local motion detector responses to a rigidly moving shape vary in both direction and speed according to the local contour orientation. This is because the perceived motion of any given point on the shape is influenced by how that point's orientation interacts with the overall motion of the shape. Different parts of the shape may seem to move differently based on their orientation relative to the direction of motion.
