Olfaction

Smell

Cilia

Hair cells that receive odor molecules: hair cells as a receptor

Olfactory

Smell chemicals that communicate a message

Taste Receptors

Chemical Receptors that decode molecules of food or drink to identify them

Cutaneous Receptors

Skin; Touch

Gate-Control Theory

theory that the spinal cord contains a neurological “gate” that blocks pain signals or allows them to pass on to the brain. The “gate” is opened by the activity of pain signals traveling
up small nerve fibers and is closed by activity in larger fibers or by information coming from the brain. (p. 250)

Vestibular Sense

the sense of body movement and position, including the sense of balance. (p. 258)

Kinesthesis

the system for sensing the position and movement of individual body parts. (p. 257)

Closure

Tendency to perceive a complete or whole picture even with gaps in it

Proximity

Grouping things together that are physically near to each other

Similarity

People think of similar objects as belonging together

Continuity

People organize their thoughts to see clear, smooth, continuous patterns

Common Fate

Grouping things that are together

Gestalt

Organized whole, shape, or form

Illusion

Inaccurate perception

Mueller-Lyer Illusion

Two arrowhead pictures in which one line looks longer than the other

Stroboscopic Motion

Illusion of movement produced by shown, rapid progression

Monocular Cues

depth cues, such as interposition and linear perspective, available to either eye alone. (p. 238)

Binocular Cues

depth cues, such as retinal disparity, that depend on the use of two eyes. (p. 237)

Retinal Disparity

a binocular cue for perceiving depth: By comparing images from the retinas in the two eyes, the brain computes distance—
the greater the disparity (difference) between the two images, the closer the object. (p. 237)

Color Constancy

The ability to perceive an object the same color regardless of the environment

Brightness Constancy

By taking an average, the human visul network keeps brightness constant as an object is moved to various environments

Space Constancy

Keeping objects in the environment steady

Size Constancy

The ability to retain the size of an object regardless of where it is located

Depth Perception

The ability to see objects in space

Visual Cliff

a laboratory device for testing depth perception in infants and young animals. (p. 236)

Binocular Disparity

The difference between the image provided by each eye; when the images are brought together they provide depth

Visual Texture

Depth perception based on how rough or smooth objects viewed appear
