pinna
|
The external flap of tissue commonly referred to as the “ear”; it helps direct sounds toward the tympanic membrane
|
|
pitch
|
The psychological experience that results from the auditory processing of a particular frequency of sound
|
|
place theory
|
The idea that the location of auditory receptor cells activated by movement of the basilar membrane plays a role in the perception of pitch
|
|
psychophysics
|
A field of psychology in which researchers search for ways to describe the transition from the physical stimulus to the psychological experience of that stimulus
|
|
pupil
|
The hole in the centre of the iris through which light enters the eye; the size of the pupil changes with light intensity
|
|
receptive field
|
In vision, the portion of the retina that, when stimulated, causes the activity of a higher-level neuron (such as a ganglion cell or an even higher-level neuron in the visual cortex) to change
|
|
recognition by components
|
The idea proposed by Biederman that people recognize objects perceptually through smaller components called geons
|
|
retina
|
The thin layer of tissue that covers the back of the inside of the eye and contains the light-sensitive receptor cells for vision
|
|
retinal disparity
|
A binocular cue for depth that is based on differences between the images in each eye
|
|
rods
|
Receptor cells in the retina, located mainly on the periphery of the retina, that transduce light energy into neural inputs; these visual receptors are highly sensitive and are active in dim light
|
|
semicircular canals
|
A receptor system attached to the inner ear that responds to movement, acceleration, and deceleration and to changes in upright posture
|
|
sensations
|
The elementary components, or building blocks, of perception, such as a pattern of light and dark contrast detected by the eye or a bitter taste on the tongue
|
|
sensory adaptation
|
The tendency of sensory systems to reduce sensitivity to a stimulus that remains constant
|
|
signal detection
|
A technique that can be used to determine an individual’s ability to detect the presence of a stimulus and to measure the individual’s response bias
|
|
sound
|
The physical input to the auditory system, a mechanical energy travelling in waves that requires a medium, such as air or water, through which to move
|
|
taste buds
|
The receptor cells on the tongue involved in taste
|
