Psych Chapter 3
vision,hearing,sense etc
| Term | Definition |
|---|---|
| Sensory Receptors | cells unique to each sense organ (responds to form of sensory stimulation |
| Transduction | physcial energy is converted to coded neural signal |
| Absolute threshold | smallest amount of strength of a stimulus that can be detected half the time |
| difference threshold | smallest difference between 2 stimuli that can be detected |
| Sensory adaption | nose blind, decline in sensitivity |
| wave length | distance from one wave peak to another |
| Cornea | membrane covering visible part of the eye (gathers direct incoming of light) |
| pupil | opening in middle of the eye that changes size to let diff amount of light in |
| iris | colored part of the eye that controls the size of the pupil |
| lens | transparent structure behin pupil that focuses or bends light that enters the eye |
| accommodation | changes shape to focus incoming light so that it calls on retina |
| rods | sensory receptors for light (peripheral vision?night vision) |
| cones | detect color and are responsible for color/day visual activity |
| fovea | small area in center of retina (cones/visual info) |
| optic disk | no rods or cones (retina) optic nerve exits in back of eye |
| why does a blind spot happen ? | optic nerve leaves the eye(small gap in vision) |
| ganglion cells | specialized neurons tat connect to bipolar (forms optic nerve) |
| bipolar cells | conncet rods and cones with ganglion cells |
| optic nerve | thick nerve that exists from back of eye (carries visual info to v cortex in brain) |
| optic chiasm | optic nerve fibers from each eye meet and cross over to the opposite side of brain |
| trichromatic theory of color vision | sensation of color results because cones are sensitive to red,green,blue (long-short wave lengths) |
| after image | when stimulation is no longer present |
| opponent process theory of color | opposing pairs green red, yellow blue. when one membrane is stimulated the other is inhibited |
| basilar membrane | contains hair cells |
| hair cells | sensory receptors for sound (embedded in basilar membrane of cochela |
| cochlea | fluid filled inner ear structure that contains basilar membrane and hair cells |
| frequency theory | basilar membrane vibrates at same frequency as sound wave |
| place theory | frequencies cause larger vibrations @ diff locations along bm |
| olfaction | sense of smell |
| gustation | sense of taste |
| pheromones | communicate info to other animal of same species |
| olfactory bulb | enlarged ending of of. cortex (smell is registered) |
| taste buds | receptors on mouth and throat |
| nociceptors | sensory receptors in skin, muscles,organs |
| substance P | neuro transmitter involved in pain messages to brain |
| gate control theory of pain | pain s psychology factors that cause spinal gates to open and relay patterns to the brain (perceives pain) |
| kinesthetic sense | sense of location and position of body parts in relation to another |
| proprioceptors | in muscles and joints that provide info about body position and movement |
| vestibular sense | technical name for the sense of balance or equilibrium |
| parapsychology | investigation of claims of paranormal phenomena abilities |
| figure ground relationship | principle stating that perception is divided into figure which stands out form distinct background, the ground |
| Perceptual constancy | Tendency to perceive objects especially familiar objects,as constant and unchanging despite in sensory input |
| Size constancy | Perception of an object maintains the same size despite changing images on the retina |
| Shape constancy | Object perception remaining the same shape regardless the image produced in retina |
| Color constancy | Perception of a familiar object as being the same color under different light conditions |
| Perceptual illusion | Misperception of true characteristics of an object or an image |
| Müller-Lyer illusion | Visual illusion involving misperception of the identical length of two lines One with arrows pointed inward and the other outward |
| Moon illusion | Visual illusion that the moon is larger when it's on the horizon than when it is directly overhead |
| Biofeedback | Technique that involves autidory/visual feedback to learn to exert voluntary controll over involuntary things (heart rate etc) |
| Acupuncture | Chinese medical procedure where needles are put on pain areas to alliveate it |
