Perception Flashcards
Perception
Process of organizing & interpreting sensory information about objects, events, & spatial layout of our world
Sensation
Processing of basic information from the external world by the sensory receptors in the sense organs (eyes, ears, skin, etc.)
Preferential looking technique
Method for studying visual attention by observing which object the infant stares at longer
Visual acuity
•how clearly one can see
•develops rapidly
-~ 8 months infant’s vision approaches that on an adult
-full adult acuity reached around 6
Infants and faces
- from birth, are able to perceive & discriminate between faces
- prefer female faces to male faces
Novelty preference
Tendency to fixate on novel stimulus
Perceptual constancy
The perception of objects as being of constant size, shape, color, etc.
Object segregation
Perception of separate objects in a visual array
Intermodal perception
Combining of information from 2 or more sensory systems
Novel stimuli
Indicates that they can differentiate between 2 stimuli
Unexpected/impossible events
Indicates that they have some understanding of object properties
Stimuli that are consistent w/ other info
Looking longer at a toy they just manually felt
Optical expansion
Depth cue in which object occludes more of a background as it approaches
Binocular disparity
As a result of distance between 2 eyes, closer objects result in greater disparity between 2 images
Monocular depth cues
Perceptual cues of depth perceived by one eye
Auditory localization
Perception of location in space of sound
Scale errors
Dramatic failure integration of perception and action
