Discussion Thread: Goodale and Humphrey

After reading the articles, respond to the following prompts.

· What does the Goodale and Humphrey (1998) article mean by “the field’s preoccupation with vision as sight?"

· How did Goodale and Humphrey’s view of the ventral and dorsal visual stream differ from the earlier theory of Ungerleider and Mishkin (1982)?

· Discuss the evidence presented by Goodale and Humphrey to support their view. How has learning about the brain’s two separate visual systems changed the way you think about your own visual experience?

· Finally, Goodale and Humphrey (1998) refer to the two visual systems as having evolved. Compare and contrast the evolutionary approach to function of the brain with the Tripartite Man’s approach.
