The process by which the eye’s lens changes shaped to focus objects in the retina 

The minimum threshold needed to detect a particular stimulus 50% of the time 

Depth cues, such as retinal disparity, that depend on the use of 2 eyes 

A condition in which a person can respond to a visual stimulus without consciously experiencing it

The point at which the optic nerve leaves the eye, creating a “blind” spot because no receptor cells are located there 

Analysis that begins with the sensory receptors and works up to the brain’s integration of sensory information 

Failing to notice changes in the environment 

A coiled, bony fluid-filled tube in the inner ear; sound waves traveling through the cochlear fluid trigger nerve impulses 

A device for converting sounds into electrical signals and stimulating the auditory nerve through electrodes threaded into the cochlea 

Perceicing familiar objects as having consistent color, even if changing illumination alters the wavelengths reflected by the object

Retinal receptor cells that are concentrated near the center of the retina and that functions in day-light or well-lot conditions. The cones detect fine detail and give rise to color sensations 

Hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea 

The ability to see objects in 3 demensions although the images that strike the retina are 2 demensional. Allows us to judge distance 

The minimum difference between 2 stimuli required for detection 50% of the time. We experience the difference threshold as a just noticeable different (JND)

The principle that information is often simultaneously processed on separate conscious and unconscious tracks 

In psychological science, the influence of bodily sensations, gestures, and other states on cognitive preferences and judgments

Nerve cells in the brain that respond to special features of the stimulus. Such as shape, angle, or movement 

The organization of the visual field into objects (figures) that stand out from their surrounding (ground)

The central focal point in the retina, around which the eye’s cones cluster 

The number of complete wavelengths that pass a point in a given time (EX) per second 

In hearing, the theory that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, thus enabling us to sense its pitch 

The theory that the spinal cord contains a neurological “gate” that blocks pain signals or allows them to pass on to the brain. The “gate” in opened by the activity of pain signal traveling up small nerve fibers and is information coming from the brain

An organized whole. Gestalt psychologists emphasized our tendency to integrate pieces of information into meanhfil wholes 

The perceptual tendency to organize stimuli into coherent groups 

The dimension of color that is determined by the wavelength of light. What we know as the color names: blue, green and so forth 

Failing to see visible objects when our attention is directed elsewhere 

The innermost part of the ear, containing the cochlea, semicircular canals, and vestibular sacs

The amount of energy in a light or sound wave, which we perceive as brightness or loudness, as determined by the waves amplitude 

A ring of muscle tissue that forms the colored portion of the eye around the pupil and controls the size of the pupil opening 

The system for sensing the position and movement of individual body parts 

The transparent structure behind the people that changes shape doubt focus images in the retina

The chamber between the eardrum and cochlea containing 3 tiny bones (hammer, anvil and stirrup) that concentrate the vibrations of the year. Check on the cochleas oval window.

Depth cues, such as interposition and linear perspective, available to either eye alone

Sensory receptors that enable the perception of pain in response to potentially harmful skills

The Siri, the opposing retinal processes (red-green, yellow-blue, white-black) enable color vision. (EX) some cells are stimulated by green and inhibited by red, others are stimulated by red and inhibited by green

The nerve that carries neural impulses from the eye to the brain

The processing of many aspects of a problem simultaneously. The brain’s natural mode of information processing for many functions

The process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events

In vision, the ability to adjust to an artificially displaced, or even inverted visual field

Perceicing objects as unchanging, (having consistent shapes, size, brightness, and color) even as illumination and retinal images changes 

A mental predisposition to perceive one thing and not another

An illusion of movement created when two or more adjacent lights, blink on and off in quick succession

A tones experienced highness or lowness. Depends on frequency

In hearing, the theory that links the pitch, we hear with the place where the cochlea‘s membrane is stimulated

The activation, often unconsciously, of certain associations, thus predisposing one’s perception, memory or response 

The study of relationships between the physical characteristics of stimuli, such as their intensity, and our psychological experience of them

The adjustable opening in the center of the eye through which left enters 

The light-sensitive inner surface of the eye, containing the receptor rods and cones plus layers of neurons that begin the processing of visual and formation

A binocular cues for perceiving death. By comparing images from the written us in the two eyes, the brain compute distance. The greater the disparity, difference, between the two images, the closer the object

Retinal receptors that detect a black, white, and gray. Necessary for peripheral and twilight vision, when cones don’t respond

The focusing of conscious awareness on a particular stimulus

The process by which are sensory receptors in nervous system receive and represent stimulus energies from our environment

Hearing loss caused by damage to the cochleas, receptor cells or to the auditory nerves. Also called nerve deafness

Diminished sensitivity as a consequence of constant stimulation

The principle that one sense may influence another, as when the smell of food influences its taste

A Siri predicting how, and when we detect the presence of a faint stimulus amid background stimulation. As soon as there is no single, absolute threshold, and that detection, depends on, partly on one’s experience, expectations, motivation, and alertness

Below one’s absolute threshold for conscious awareness 

Information processing, guided by higher level, mental processes, as when we construct perceptions drawing on our experience and expectations

Conversion of one form of energy into another. In temptation, the transforming of stimulus energies, such as sides, sound, and smells, into neural impulses our brain can interpret.

The sense of body movement in position, including the sense of balance

A laboratory device for testing depth perception in infants and young animals

The distance from the piece of one light or sound wave to the peak of the next. Electromagnetic wavelengths vary from the short blips of cosmic rays to the long pulses of radio transmission

The Principal. Lol that, to be perceived, as different, to stimuli, must different by constant minimum percentage, probably rather than constant amount constant amount.

The Siri that retina contains three different color receptors- one most sensitive to red, on to green, one to blue- which, when stimulated in combination, can produce the perception of any color 

Young-Helmholtz Trichromatic (3 Color) Theory
