Binocular Depth Cues - ANSWER✔✔-Using 2 eyes, 3D


1. Binocular convergence


- Closer the object, the more eyes must turn inward


- muscles send messages to the brain regarding degree eyes are turning inward


- These messages are interpreted as cues indicating depth


2. Binocular Disparity


- Closer an object, the greater the disparity between the views of it as sensed by each eye


- apparent jumping of images between the two eyes, which indicated amount of binocular disparity

decreases with distance


Gestalt Psychology (principles related) - ANSWER✔✔-Goals: address directly the more global, holistic

processes involved in perceiving structure in the environment (describe phenomenon, but doesn't

explain it)


- Figure-ground: Figure=prominent object, ground=background


- Proximity: perceive objects that are close to each other as forming a group
