2 WELCOME TO SENSATION & PERCEPTION Defining Sensation and Perception Why Should You Care? Transduction Bottom-Up and Top-Down Processing

3 Sensation & Perception Sensation: how the sense organs respond to stimulation Perception: how the brain organizes and interprets sensory input

4 Why Should You Care? Everything we know and believe is based on sensation & perception Sensation & perception are necessary for survival Background for other topics in Psychology Applications in education, business, criminal justice

5 Transduction Conversion of environmental energy to neural processing

6 Bottom-Up Processing Processing that begins with information received on the sensory receptors

7 Top-Down Processing Processing that begins with the person’s knowledge, assumptions, and expectations
