The perception of an object as distinct from its surroundings is called:

• perceptual set

• perceptual constancy

• figure-ground perception

• the phi-phenomenon

Weber’s law is relevant to an understanding of

• absolute thresholds

• difference thresholds

• sensory adaptation

• sensory interaction

Sensory adaptation helps us to focus our attention on _______ stimuli

• familiar

• subliminal

• novel

• intense

Dilation and constriction of the pupil are controlled by the

• optic nerve

• iris

• lens

• cornea

According to the Young-Helmholtz theory

• the retina contains three kinds of color receptors

• color vision depends on pairs of opposing retinal processes

• the size of the difference threshold is proportional to the intensity of the stimulus

• certain nerve cells in the brain respond to specific features of a stimulus

Damage to the fovea would have the greatest effect on

• night vision

• peripheral vision

• sensory adaptation

• visual acuity

With her eyes closed and her nose plugged, Joan was unable to taste the difference between an onion and a pear.  Her experience best illustrates the importance of

• sensory interaction

• sensory transduction

• sensory adaptation

• kinesthesis

With her eyes closed, Sandra can accurately touch her mouth, nose, and chin with her index finger.  Her accuracy illustrates the importance of

• kinesthesis

• accommodation

• sensory interaction

• parallel processing

The coiled, fluid-filled tube in which sound waves trigger nerve impulses is called the

• Eustachian tube

• auditory canal

• semicircular canal

• cochlea
