Sensation and Perception 9th Edition by Bruce Goldstein

Exercise 2

In the present chapter we have described a number of principles that also hold for object perception. Find examples from Chapter of the following (page numbers are for this chapter).
? There are neurons that are specialized to respond to specific stimuli.
? There are parallels between physiology and perception.
? More complex stimuli are processed in higher areas of the cortex.
? Experience can affect perception.

Reichardt circuit. Green indicates excitation; orange indicates inhibition. (a) and (b) When the receptors are stimulated from left to right, neuron I does not fire. (c) and (d) When the receptors are stimulated from right to left, neuron I fires.

Figure 2
The perceptual cycle from Chapter 1. Newsome measured the physiology-perception relationship by simultaneously recording from neurons and measuring the monkey's behavioral response. Other research we have discussed, such as Hubel and Wiesel's receptive field studies, have measured the stimulus-physiology relationship.
