Sensation and Perception

CH. 1

1. Describe the process of perception as a series of seven steps, beginning with the environmental stimulus and culminating in the behavioral responses of perceiving, recognizing and acting.

2. What is the role of higher-level or "cognitive" processes in perception? Be sure you understand the difference between bottom-up and top-down processing.

3. What does it mean to say that perception can be studied using different approaches? Give an example of how each approach is applied to determine each of the relationships.

CH. 2

1. How does the focusing system at the front of our eye affect our perception?

2. How do chemicals in the eye called visual pigments affect our perception?

3. How can the way neurons are "wired up" affect our perception?

CH. 3

1. How do both excitation and inhibition determine how a neuron fires to different types of stimuli?

2. How do the responses of neurons change as we move higher in the visual system?

3. How are objects in the environment represented by the firing of neurons in the cortex?

CH. 4

1. How can brain damage affect a person's perception?

2. How has ablation been used to demonstrate the existence of ventral and dorsal processing streams? What is the function of these streams?

3. Describe the possible role of experience-dependent plasticity in determining how neurons and brain areas respond to horizontal, vertical and slanted lines, and greebles.

CH. 6

1. Why are even the most sophisticated computers unable to match a person's ability to perceive objects?

2. Can we tell what people perceive by monitoring their brain activity? Explain.

3. What are the two stages in feature integration theory? What does feature integration theory propose about the role of attention in perception and binding?

CH. 7

1. What is the connection between perceiving and moving through the environment?

2. What are mirror neurons? How do neurons called mirror neurons respond when a person perceives an action and when the person watches someone else perceive the same action?

3. Describe lacoboni's experiment that suggested that there are mirror neurons that respond to intentions.
