Unit 7: Perception
the process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events
the tendency for vision to dominate the other senses
the ability to discriminate properly between a figure and its background
tendency to perceive objects as stable and unchanging despite changing sensory info (size, shape, brightness, color)
perception of an object as the same size regardless of the distance from which it is viewed
tendency to see an object as the same shape no matter what angle it is viewed from
perceiving familiar objects as having consistent color, even if changing illumination alters the wavelengths reflected by the object
Distance cues, such as linear perspective and overlap, available to either eye alone.
a monocular cue for perceiving depth; hazy objects are farther away than sharp, clear objects
a monocular cue for perceiving depth; the more parallel lines converge, the greater their perceived distance
A monocular cue; if we assume objects are similar in size, the one that casts the smaller retinal image is farther away
a monocular cue; objects up close appear brighter than objects farther away
a monocular cue for perceiving depth; objects higher in our field of vision are perceived as farther away
a monocular cue; a graduated change in the texture, or grain, of the visual field, whereby objects with finer, less detailed textures are perceived as more distant
a monocular cue; if one object partially blocks our view of another, we perceive it as closer
The perception of an observer that, as the observer moves forward, the objects that appear to him/her to move backwards faster are closer than apparently slower-moving objects; a monocular cue.
An organized whole. Gestalt psychologists emphasize our tendency to integrate pieces of information into meaningful wholes (the whole is greater than the sum of its parts).
Gestalt laws of grouping or organization
The perceptual tendency to organize stimuli into coherent groups (proximity, similarity, continuity, connectedness and closure).
depth cues, such as retinal disparity, that depend on the use of two eyes
a binocular cue for perceiving depth; by comparing images from the two eyeballs, the brain computes distance - the greater the disparity (difference) between the two images, the close the object
a binocular cue for perceiving depth; the extent to which the eyes turn inward when looking at an object
a laboratory device for testing depth perception in infants and young animals
When presented with a rapid series of slightly varying images, the brain perceives continuous movement (e.g., film animation)
an illusion of movement created when two or more adjacent lights blink on and off in quick succession
in vision, the ability to adjust to an artificially displaced or even inverted visual field
a mental predisposition to perceive one thing and not another
a concept or framework that organizes and interprets information; the mental mold into which we pour our experiences.
The influence of the surroundings on the recognition or interpretation of patterns or objects.
Human factors psychologists
psychologists that help design appliances, machines, and work settings that harness natural perception sets (i.e., make things user-friendly and intuitive)
Extrasensory perception; the controversial claim that sensation can occur apart from sensory input
the study of paranormal events including extrasensory perception, psychokinesis, and survival of consciousness after death.
the ability to read another's thoughts or to communicate by thinking
perceiving remote events, such as sensing that a friend's house is on fire
knowledge of pending future events; premonition- feeling or warning about future events
