What is the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment?

What is the process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events?
Blur Image
What are sensory nerve endings that respond to stimuli called?
Blur Image

Blur Image
What is the term for failing to notice changes in the environment?
Blur Image
What is the conversion of one form of energy into another, specifically in sensation, the transforming of stimulus energies into neural impulses?
Blur Image
What is the study of relationships between the physical characteristics of stimuli and our psychological experience of them?
Blur Image
What is the minimum stimulation needed to detect a particular stimulus 50 percent of the time?
Blur Image
What term describes stimuli that are below one's absolute threshold for conscious awareness?
Blur Image
What theory predicts how and when we detect the presence of a faint stimulus amid background stimulation?
Blur Image
What is the minimum difference between two stimuli required for detection 50 percent of the time?
Blur Image
What principle states that to be perceived as different, two stimuli must differ by a constant minimum percentage?
Blur Image
What is the activation, often unconsciously, of certain associations, thus predisposing one's perception, memory, or response?
Blur Image
What is diminished sensitivity as a consequence of constant stimulation called?
Blur Image
What is a mental predisposition to perceive one thing and not another?
Blur Image
What term describes the circumstances, atmosphere, attitudes, and events surrounding an event?
Blur Image
What is the controversial claim that perception can occur apart from sensory input, including telepathy, clairvoyance, and precognition?
Blur Image
What is the study of paranormal phenomena, including ESP and psychokinesis?
Blur Image
What is the distance from the peak of one light or sound wave to the peak of the next?
Blur Image
What is the dimension of color that is determined by the wavelength of light?
Blur Image
What is the amount of energy in a light or sound wave, perceived as brightness or loudness?
Blur Image
What is the adjustable opening in the center of the eye through which light enters?
Blur Image
What is the eye's clear, protective outer layer, covering the pupil and iris?
Blur Image
What is the ring of muscle tissue that forms the colored portion of the eye around the pupil and controls the size of the pupil opening?
Blur Image
What is the transparent structure behind the pupil that changes shape to help focus images on the retina?
Blur Image
What is the process by which the eye's lens changes shape to focus near or far objects on the retina?
Blur Image
What is the light-sensitive inner surface of the eye, containing the receptor rods and cones plus layers of neurons that begin the processing of visual information?
Blur Image
What are retinal receptors that detect black, white, and gray, necessary for peripheral and twilight vision?
Blur Image
What are retinal receptor cells that are concentrated near the center of the retina and function in daylight or well-lit conditions?
Blur Image
What is the nerve that carries neural impulses from the eye to the brain?
Blur Image
What is the point at which the optic nerve leaves the eye, creating a spot where no receptor cells are located?
Blur Image
What is the central focal point in the retina, around which the eye's cones cluster?
Blur Image
What theory suggests that the retina contains three different color receptors sensitive to red, green, and blue?
Blur Image
What theory suggests that opposing retinal processes enable color vision, such as red-green and yellow-blue?
Blur Image
What are nerve cells in the brain's visual cortex that respond to specific features of the stimulus, such as shape, angle, or movement?
Blur Image
What is the processing of many aspects of a problem simultaneously, the brain's natural mode of information processing for many functions?
Blur Image
What is the process of grouping visual elements together to determine the meaning of the visual as a whole?
Blur Image
What term describes an organized whole, emphasizing our tendency to integrate pieces of information into meaningful wholes?
Blur Image
What is the organization of the visual field into objects that stand out from their surroundings?
Blur Image
What is the perceptual tendency to organize stimuli into coherent groups?
Blur Image
What is the ability to see objects in three dimensions, allowing us to judge distance?
Blur Image
What is a laboratory device for testing depth perception in infants and young animals?
Blur Image
What is a depth cue that depends on the use of two eyes?
Blur Image
What is a binocular cue for perceiving depth by comparing images from the retinas in the two eyes?
Blur Image
What is a binocular cue for perceiving depth, based on the extent to which the eyes converge inward when looking at an object?
Blur Image
What is a depth cue available to either eye alone, such as interposition or linear perspective?
Blur Image
What is an illusion of movement created when two or more adjacent lights blink on and off in quick succession?
Blur Image
What is the perception of objects as unchanging even as illumination and retinal images change?
Blur Image
What is the perception of familiar objects as having consistent color, even if changing illumination alters the wavelengths reflected by the object?
Blur Image
What is the ability to adjust to an artificially displaced or even inverted visual field?
Blur Image
What is the sense or act of hearing called?
Blur Image
What is the number of complete wavelengths that pass a point in a given time?
Blur Image
What is a tone's experienced highness or lowness, which depends on frequency?
Blur Image
What is the chamber between the eardrum and cochlea containing three tiny bones that concentrate the vibrations of the eardrum on the cochlea's oval window?
Blur Image
What is the innermost part of the ear, containing the cochlea, semicircular canals, and vestibular sacs?
Blur Image
What is a coiled, bony, fluid-filled tube in the inner ear through which sound waves trigger nerve impulses?
Blur Image
What is the less common form of hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea?
Blur Image
What is hearing loss caused by damage to the cochlea's receptor cells or to the auditory nerves, also known as nerve deafness?
Blur Image
What is a device for converting sounds into electrical signals and stimulating the auditory nerve through electrodes threaded into the cochlea?
Blur Image
