1. Frequency

In audition, the number of cycles per second in a sound wave that is responsible for the pitch of the sound; the measure of frequency is the hertz, which equals one cycle per second

2. Frequency Theory of Pitch Perception

Maintains that the number of nerve impulses sent to the brain by the hair cells of the cochlea corresponds to the frequency of the sound wave; this theory is accurate at low frequencies

3. Gate Control Theory

A theory of pain that postulates the existence of gating mechanisms in the spinal cord and brain that can increase of decrease the experience of pain by regulating the flow of pain impulses to the brain

4. Gestalt Laws of Perceptual Organization

The notion that people group and interpret stimuli in accordance with similarity, proximity, closure, and continuity

5. Gustation

The sense of taste

6. Hering's Opponent-Process Theory

The color vision theory stating that the retina contains three sets of color receptors that response differentially to red-green, blue-yellow, and black-white; the opponent processes that result can produce a perception of any hue

7. Hertz

The measure of sound-wave frequency as cycles per second

8. Illusions

Incorrect perceptions based on false perceptual hypotheses that often result from constancies that do not apply to the stimuli in question

9. Inattentional Blindness

The failure of unattended stimuli to register in consciousness

10. Kinesthesis

The body sense that provides feedback on the position and movements of our body parts

11. Lens

The transparent structure behind the pupil that changes its shape to focus images on the retina

12. Menstrual Synchrony

The tendency for some women who live together or are close friends to become more similar to one another in the timing of their menstrual cycles over time

13. Monocular Depth Cues

Depth cues that require only one eye; include linear perspective, decreasing size, height in the horizontal plane, texture, clarity, light and shadow, motion parallax, and interposition

14. Nerve Deafness

Hearing loss caused by damage to the cochlear receptor cells or to the auditory nerve

15. Olfaction

The sense of smell

16. Olfactory Bulb

A forebrain structure that receives input from the receptors for the sense of smell

17. Optic Nerve

The bundle of ganglion cell axons that carries information from the visual receptors to the visual area of the thalamus

18. Organ of Corti

Structures embedded in the basilar membrane that contain the hair cell receptors for sound

19. Perception

The process of organizing stimulus input and giving it meaning

20. Perceptual Constancies

The ability to recognize stimulus characteristics - size, color, and so on—under varying conditions
