Cards

Term
Sensation
Definition
The experience resulting from the stimulation of a sense organ.
Term
Perception
Definition
The interpretation of sensory stimulation based on experience
Term
Attention
Definition
The selection of particular sensory input for perceptual and cognitive processing and the exclusion of competing input.
Term
Haptic perception
Definition
The perceptual experience that results from active exploration of objects by touch.
Term
Vestibular sensitivity
Definition
The perceptual experience that results from motion of the body and the pull of gravity.
Term
Preference method
Definition
A research method for the study of visual ability in infancy. Two visual stimuli are presented simultaneously, and the amount of time the infant looks at each is measured.
Term
Visual acuity
Definition
The clarity with which visual images can be perceived.
Term
Size consistency
Definition
The experience that the physical size of an object remains the same even though the size of its projected image on the eye varies.
Term
Shape constancy
Definition
The experience that the physical shape of an object remains the same, even though the shape of its projected image on the eye varies.
Term
Brightness constancy
Definition
The experience that the brightness of an object remains the same, even though the amount of light it reflects back to the eye changes (because of shadows or changes in the illuminating light).
Term
Colour constancy
Definition
The experience that the colour of an object remains the same, even thought the wavelengths it reflects back to the eye change (because of changes in the colour of the illuminating light).
Term
Visual cliff
Definition
A research method for the study of depth perception in infancy. The infant is placed on a glass-covered table near an apparent drop-off, and perception of depth is inferred if the infant avoids the drop.
Term
Pictorial cues
Definition
Visual cues that indicate the relative distances of objects through static, picturelike information—for example, interposition of one object in front of another.
Term
Kinetic cues
Definition
Visual cues that indicate the relative distances of objects through movements of the objects or of the observer.
Term
Motion parallax
Definition
An observer’s experience that a closer object moves across the field of view faster than a more distant object when both objects are moving at the same speed or when the objects are stationary and the observer moves.
Term
Orienting reflex
Definition
A natural reaction to novel stimuli that enhances stimulus processing and includes orientation of the eyes and ears to optimize stimulus reception, inhibition of ongoing activity, and a variety of physiological changes.
Term
Defensive reflex
Definition
A natural reaction to novel stimuli that tends to protect the organism from further stimulation, and that may include orientation of the stimulus receptors away from the stimulus source and a variety of physiological changes.
Term
Selective attention
Definition
Concentration on a stimulus or event with attendant disregard for other stimuli or events.
