5130 - Sensation and Perception video - notes

1. The brain adapts to changes in perception (football player with vision changed by 20 degrees), and then requires new data to re-adjust when the perception is changed again.

2. Our perception is greatly influenced by its context. We see what we expect to see. We see with our minds as well as our eyes.

3. What we perceive the world as is subject to a number of influences - some will lead us astray. Previous experience, expectations, interests, and biases constantly impact our perceptions.

4. Old woman/young woman drawing, and rat/old man drawing illustrate how our perception is influenced by our mindset prior to seeing the drawing.

5. Perception has to work fast - if we relied on gathering all information, we would react too slowly.
