the organization, identification, and interpretation of a sensation in order to form a mental representation
what takes place when many sensors in the body convert physical signals from the environment into neural signals sent to the central nervous system
methods that measure the strength of a stimulus and the observer's sensitivity to that stimulus
The just noticeable difference of a stimulus is a constant proportion despite variations in intensity
Signal detection theory
the response to a stimulus depends both on a person's sensitivity to the stimulus in the presence of noise and on a person's response criterion
the region of the sensory surface that, when stimulated, causes a change in the firing rate of that neuron
the difference in the retinal image of the two eyes that provides info about depth
the perception of movement is a result of alternating signals appearing in rapid succession in different locations
a structure in the inner ear that undulates when vibrations from the ossicles reach the cochlear fluid
used mainly for high pitch frequencies, is active when the cochlea encodes different frequencies at different locations along the basilar membrane
registers low frequencies via the firing rate of action potentials entering the auditory nerve
results from our active exploration of the environment by touching and grasping objects with our hands
A theory of pain perception based on the idea that signals arriving from pain receptors in the body can be stopped
the three fluid-filled semicircular canals and adjacent organs located next to the cochlea
biochemical odorants emitted by other membranes of their species that can affect the animal's behavior or physiology
