Chapter 4.3 Sensory and perceptual development Flashcards
sensation
The product of the interaction between information and the sensory receptors—the eyes, ears, tongue, nostrils, and skin.
perception.
The interpretation of what is sensed
ecological view
The view that perception functions to bring organisms in contact with the environment and to increase adaptation.
affordances
Opportunities for interaction offered by objects that fit within our capabilities to perform functional activities.
visual preference method
A method used to determine whether infants can distinguish one stimulus from another by measuring the length of time they attend to different stimuli.
habituation
Decreased responsiveness to a stimulus after repeated presentations of the stimulus.
dishabituation
Recovery of a habituated response after a change in stimulation.
size constancy
The recognition that an object remains the same even though the retinal image of the object changes as the observer moves toward or away from the object.
shape constancy
The recognition that an object’s shape remains the same even though its orientation to the observer changes.
intermodal perception
The ability to relate and integrate information from two or more sensory modalities, such as vision and hearing.
What are the sensory receptors?
Eyes, ears, tongue, nostrils and skin
What is perceptual narrowing?
in which infants are more likely to distinguish between faces to which they have been exposed than faces that they have never seen before
What is the nativist view?
In the nativist view, the ability to perceive the world in a competent, organized way is inborn or innate.
A completely nativist view of perceptual development no longer is accepted in developmental psychology.
Empiricists
those who emphasize learning and experience
