Study Notes
Perception Organization
- Visual perception is organized by depth, form, motion, and constancy, aiding in understanding and interacting with the environment.
Depth Perception
- Depth perception assesses the distance and closeness of objects.
- Binocular vision and having two eyes is essential.
- Retinal disparity occurs because eyes are 2.5 inches apart, providing slightly different views.
- The brain merges these two images to create a single image, which gives a sense of depth.
- Convergence happens when eye muscles relax for distant objects, and turns inward for close objects.
- The brain uses the degree of eyeball turn to gauge depth.
Form Perception
- Monocular cues are visual cues that only require one eye.
- Relative size is a monocular cue where larger objects are perceived as closer.
- Interposition is a monocular cue, where an object blocking another is seen as closer.
- Relative height is a monocular cue, where higher objects are perceived as further away.
- Shading and contour are monocular cues that use light and shadow to discern an object's form.
Motion Perception
- Motion perception is used to identify if an object is moving or not.
- Motion parallax (relative motion) is a monocular cue.
- In motion parallax, closer objects appear to move faster, while distant ones seem to move slower.
Constancy
- Constancy helps maintain stable perceptions despite changing sensory input.
- Size constancy allows the recognition that objects are the same size.
- This is irrespective of distance and changes in retinal image size.
- Shape constancy means perceiving objects as having the same shape.
- This is irrespective of viewing angle and changes in retinal image.
- Color constancy means the perception of consistent color remains.
- This is irrespective of changes in lighting conditions.
