PSYB51H3 Lecture Notes - Lecture 7: Horopter, Social Cue, Retina
Document Summary
Images or objects projected on corresponding pieces of the retina. We turn our eyes toward something ex. when finger is moving closer to our faces. All the points on that surface have zero disparity. Horopter is located wherever the eyes are focused on: if looking at our finger in front of us, the horopter is smaller, when looking at something far away, horopter is bigger. Attention (selective) is a cognitive brain mechanism that lets one process different information and block out that which is irrelevant or distractive. Arousal: global state of the brain reflecting an overall level of responsiveness: varies depending on how alert or aroused we are can take in more or less information. Bottlenecks: having something that has a wide opening, then becomes narrow then becomes wide again: ex. having a bottle. Limitations to how much can flow in and out: impossible to process everything at the same time.
