• A. Ossicle
• B. Nerve
• C. Conduction
• D. Auditory

Explanation: Nerve, or sensorineural, deafness results from damage to the inner ear or auditory nerve, which ordinary hearing aids cannot repair.

• A. High frequency and high amplitude
• B. Low frequency and high amplitude
• C. Low frequency and low amplitude
• D. High frequency and low amplitude

Explanation: Sensorineural hearing loss commonly affects high-frequency sounds first, while low-amplitude sounds are also harder to detect because they…

• A. Wavelength
• B. Decibels
• C. Phonemes
• D. Hertz

Explanation: Hearing intensity is measured in decibels, and zero decibels is used as the conventional reference point for the average human hearing…

• A. Ultraviolet light
• B. White light
• C. Orange light
• D. Infrared light

Explanation: Red, green, and blue are the primary colors of additive light mixing; combining them at equal intensities produces white light.

• A. Blue; yellow
• B. Red; blue-violet
• C. Red; green
• D. Black; white

Explanation: Within the visible spectrum, red has the longest wavelength and violet or blue-violet has the shortest.

• A. Auditory localization
• B. Auditory convergence
• C. Perceptual set
• D. Perceptual constancy

Explanation: Auditory localization is the ability to identify where a sound originates, using differences in timing and intensity between the ears.

• A. Irregularities in the visual cortex
• B. Nutritional or traumatic damage to the sensory nerves
• C. Physical abnormalities in the structure of the eye
• D. Defective processing of sensory information in the visual cortexGet Study Guides

Explanation: Nearsightedness, farsightedness, and astigmatism result from structural or focusing abnormalities in the eye, such as the shape of the…

• A. Below threshold
• B. Bravely perceptible
• C. Easily perceptible
• D. Superimposed

Explanation: Subliminal stimuli are presented below the absolute threshold, meaning they are too weak to be consciously detected reliably.

• A. On the top of the tongue
• B. In the middle of the tongue
• C. On the sides of the tongue
• D. In all of the above places

Explanation: Taste buds are distributed across the tongue, including its top, middle, and sides, rather than being confined to separate taste zones.

• A. Pitched sounds at any tone are association with large vibrations of the basilar membrane closest to the oval window
• B. High-pitched sounds is associated with large vibrations of the basilar membrane closest to the oval window
• C. High-pitched sounds is associated with large vibrations of the eardrum closest to the oval window
• D. Low-pitched sounds is associated with large vibrations of the basilar membrane closest to the oval window

Explanation: Place theory links pitch to the location of maximum vibration on the basilar membrane: high-frequency sounds peak near the oval window…

• A. Green
• B. Orange
• C. Red
• D. Yellow

Explanation: The Young-Helmholtz theory proposes separate red-, green-, and blue-sensitive cones whose combined activity produces color experiences.

• A. They have used telepathy to read the mind of the criminal
• B. They have provided useful predictions using all their powers in 90 percent of the cases
• C. They have used precognition to forewarn the police of criminals acts
• D. They have reported visions that are no more accurate than guesses

Explanation: Controlled investigations have found that alleged psychic visions used in crime solving are generally no more accurate than guesses.

• A. Depth perception is due to the cornea of the eye
• B. Women test better at it than men
• C. Men test better at it than women
• D. Depth perception is associated with the opponent-process theory

Explanation: Depth perception depends on binocular and monocular cues such as retinal disparity, convergence, interposition, and relative size, not on…

• A. Complete in both his rods and cones
• B. Not taking place in his cones, but complete in his rods
• C. Complete in his cones, but still taking place in his rods
• D. Still taking place in both his rods and his cones

Explanation: Cones adapt quickly and are usually fully adapted after about 10 minutes in darkness, whereas rods continue adapting for much longer…

• A. Hearing
• B. Accommodation
• C. Parallel processing
• D. The vestibular senseTry Prep Courses

Explanation: The semicircular canals are fluid-filled organs of the vestibular system that detect rotational movement of the head and support balance.

• A. Complementary color theory
• B. Trichromatic theory
• C. Opponent-process theory
• D. Saturation theory

Explanation: Trichromatic theory holds that color vision depends on three types of cones sensitive to different primary colors, whose signals combine…

• A. Sensory interaction; feature detection
• B. Sensation; perception
• C. Absolute threshold; difference threshold
• D. The just noticeable difference; accommodation

Explanation: Detecting the pitches of separate sounds is sensation, the registration of physical stimulation by the senses.

• A. Subtractive color mixing
• B. Divisive color mixing
• C. Trichromatic theory
• D. Multiplicative color mixing

Explanation: Paint absorbs, or subtracts, wavelengths of light, so mixing yellow and blue pigments produces green through subtractive color mixing.

• A. Subliminal cells
• B. Ganglion cells
• C. Rods and cones
• D. Bipolar cells

Explanation: Rods and cones lie closest to the back, or outer wall, of the retina, where they receive light before signals pass toward bipolar and…

• A. Transduction
• B. Sensory adaptation
• C. Parallel processing
• D. Accommodation

Explanation: Transduction is the conversion of physical energy into neural signals; in hearing, hair cells convert sound vibrations into neural…
