Week One Worksheet

Respond to the following questions in 75 to 150 words each.

Perception is the process in the brain that helps us to make sense of what we are touching or hearing or tasting or why it hurts. Sensation is the actual sense we get out of the information the brain is sending. While they work closely together they are two sperperate things. 2.
