Sensation- The series of processes that together that receive and represent different environmental stimuli
Perception- The process in which we understand sensory information
Bottom-up processing- Analysis of sensations that starts with each individual stimuli being analyzed then works up to the whole sensation at once
Top-down processing- Analyzing the entire range of stimuli at once, trying to relate it to memory or thoughts
Psychophysics- The relationship between psychological experiences and physical energy
Absolute threshold- The minimum level of stimulus necessary to detect a specific stimulus half of the time
Signal detection theory- A theory which states that threshold of a sensation depends on a number of factors
Subliminal stimulation- Stimulation below the threshold
Difference threshold (JND)- The minimum amount of difference that is noticeable between two stimuli
Weber's law- The JND between two stimuli as their strength varies is a percentage of that strength, not a constant
Sensory adaptation- Decreased sensitivity to a certain stimuli because of repetition
Transduction- Changing energy from one form into another, in sensation, changing stimuli into neural impulses
Wavelength- The distance necessary for a wave to perform a cycle (trough to trough, peak to peak, etc.)
Hue- The arbitrary assignment of 'color' to a certain frequency band of light
Intensity- The amount of energy that a wave carries (influenced by amplitude and frequency)
Pupil- The adjustable opening of the eye which light passes through
iris- The rig of muscle that controls the pupil's dilation and contraction
Lens- The transparent structure behind the pupil that focuses the light onto the retina
Accommodation- The process by which the eye's lens changes shape to focus an image properly on the retina
Retina- The inner surface of the eye which is host to layers of cones, rods, and neurons.
Acuity- clarity of sight
nearsightedness-A malfunction of the eye which causes nearby objects to be seen clearer than far objects
Farsightedness- A malfunction of the eye which causes far objects to be seen clearer than near objects
Rods- Photoactive cells that don't measure color but measure intensity
Cones-Photoactive cells that measure color
Optic nerve-The bundle of nerves that connects the eye to the brain
Blind spot- A part of the retina that has no photoactive cells; where the optic nerve leaves the eye
Fovea- The central focal point in the retina, around which cones cluster
Feature detectors- The breaking down,processing independently, then restructuring of visual information
Parallel processing- Processing different parts of the same problem at the same time
Trichromatic theory- Young-hemholtz's theory that the retina is sensitive to red, green, and blue, only
Opponent process theory- The theory that complimentary colors enable color vision
Color constancy- The deception/illusion that the color of an object is the save under different lighting
Audition- hearing
Pitch- The interpretation of frequency, similar to seeing colors
Frequency- The amount of times that a wave cycles in a unit of time (usually seconds)
Middle ear- The chamber which contains bones which help transmit sound to the inner ear
Inner ear- Innermost part of ear which contains the cochlea, semicircular canals, and the vestibular sacs
Cochlea- A tube with fluid and home to the cilia
Place theory- A theory which tries to correlate the pitch we hear and the place in the cochlea the cilia detected it
Frequency theory- A theory which states that the frequency of a tone is the same as the rate of a cilia's firings
Conduction hearing loss- A loss of hearing caused by a failure in the means of conducting sound to the inner ear
Sensorineural hearing loss- Hearing loss caused by damage to the cilia or auditory nerves
Gate-control theory- A theory which states that the spinal cord contains a gate which controls neural signal flow
Sensory interaction- The idea that one sense can interact with another (ex: smell and taste)
Kinesthesis- The body's system for sensing the position and movement of muscles, tendons, and other body parts
Vestibular sense- The sense of position, movement, and balance
