PSYC304 Perception

Week 6 Forum

The idea behind selective adaptation is that when we view a stimulus with a specific property, neurons tuned to that property fire, and if viewing continues for long enough, these neurons adapt. Discuss how the psychophysical procedure of selective adaptation has been used to demonstrate the link between feature detectors and (a) the perception of orientation, and (b) the perception of size. Be sure to include a discussion of your understanding of the rationale behind selective adaptation experiments and how we can draw conclusions about physiology from the results of such a psychophysical procedure. Provide two examples for the class that support your conclusions. For this week’s discussion, it is expected students will use their readings and outside scholarly web sources to answer this question completely.
