synesthesia
means "joined sensation" a diorder in which the signals from various sensory organs are processed in the wrong cortical areas, resulting in the sense information being interreted as more then one sensation. TERM 2
transduction
DEFINITION 2 defined as converting one form of energy into another. TERM 3
sensory receptors
DEFINITION 3 In a sensory system, a sensory receptor is a sensory nerve ending that responds to a stimulus in the internal or external environment of an organism. TERM 4
absolute threshold
DEFINITION 4 In neuroscience and psychophysics, an absolute threshold is the smallest detectable level of a stimulus. TERM 5
subliminal perception
DEFINITION 5 Subliminal stimuli (, literally "below threshold"), contrary to supraliminal stimuli or "above threshold", are any sensory stimuli below an individual's absolute threshold for conscious perception.
habituation
Habituation, a form of non-associative learning, is the psychological process in humans and other organisms in which there is a decrease in psychological and behavioral response to a stimulus after repeated exposure to that stimulus over a duration of time. TERM 7
sensory adaptation
DEFINITION 7 Neural adaptation or sensory adaptation is a change over time in the responsiveness of the sensory system to a constant stimulus. taste, touch, smell, and vision receptor cells themselves become less responsiveto an unchanging stimulus, TERM 8
visual accommodation
DEFINITION 8 allows the eye to focus on objects that areclose or far away TERM 9
rods and cones
DEFINITION 9 A photoreceptor, or photoreceptor cell, is a specialized type of neuron (nerve cell) found in the eye's retina that is capable of phototransduction. TERM 10
blind spot
DEFINITION 10 A blind spot, also known as a scotoma, is an obscuration of the visual field.
color blindness
Color blindness or color vision deficiency is the decreased ability to perceive differences between some of the colors that others can distinguish. TERM 17
hertz
DEFINITION 17 The hertz (symbol: Hz) is the SI unit of frequency defined as the number of cycles per second of a periodic phenomenon. TERM 18
pinna
DEFINITION 18 The pinna (Latin for feather) is the visible part of the ear that resides outside of the head .serves as a kind of concentrator, funneling the sound waves from the outside into the structure of the ear TERM 19
auditory canal
DEFINITION 19 The ear canal (external auditory meatus, external acoustic meatus) () , is a tube running from the outer ear to the middle ear. TERM 20
cochlea
DEFINITION 20 The cochlea is the auditory portion of the inner ear.
auditory nerve
The cochlear nerve (also auditory or acoustic nerve) is a nerve in the head that carries signals from the cochlea of the inner ear to the brain. TERM 22
volley principle
DEFINITION 22 Volley theory, proposed by Wever and Bray (1937), attempts to account for the maximum theoretical limit for the neuronal firing of action potentials and the small time scales over which sound discrimination must occur. TERM 23
taste buds
DEFINITION 23 Taste buds contain the receptors for taste. TERM 24
gustation
DEFINITION 24 Taste (or, more formally, gustation; adjectival form: "gustatory") is one of the traditional five senses. TERM 25
olfactory
sense
DEFINITION 25 Olfaction (also known as olfactics; adjectival form: "olfactory") is the sense of smell.
sensory conflict theory
explanation of motion sickness. TERM 32
perception
DEFINITION 32 In philosophy, psychology, and cognitive science, perception is the process of attaining awareness or understanding of sensory information. TERM 33
size constancy
DEFINITION 33 the tendency to interpret an object as always being the same size, regarless of its distance from the veiwer. TERM 34
shape constancy
DEFINITION 34 Visual perception is the ability to interpret information and surroundings from the effects of visible light reaching the eye. TERM 35
brightness constancy
DEFINITION 35 veiwing the object as the same no matter where the light is hitting it.
reversible figures
in wich the figure and the ground seem to switch back and fourth. TERM 37
proximity
DEFINITION 37 Distance is a numerical description of how far apart objects are. TERM 38
similarity
DEFINITION 38 Different fields provide differing definitions of similarity: TERM 39
closure
DEFINITION 39 the tendancy to complete figures that are incomplete.. TERM 40
continuity
DEFINITION 40 refers to the tendancy to percieve things as simply as possible with a continuous pattern rather then a complex, broken up pattern.
