6 / 30

Which of the following sentences best describes the relationship between culture and perception?

(A) bottom-up processing

(B) signal detection theory

(D) opponent-process theory

(A) trichromatic theory

(B) visible hue theory

(D) dichromatic theory

(E) binocular disparity theory

10 / 30

What function does the retina serve?

(A) The retina contains the visual receptor cells.

(B) The retina focuses light coming in the eye through the lens.

(D) The retina determines which rods and cones will be activated by incoming light.

(E) The retina connects the two optic nerves and sends impulses to the left and right visual cortices.

11 / 30

Which of the following sentences best describes the relationship between sensation and perception?

(A) Sensation is a strictly mechanical process, whereas perception is a cognitive process.

(B) Perception is an advanced form of sensation.

(D) Sensation is detecting stimuli, perception is interpreting stimuli detected.

(E) Sensation involves learning and expectations, and perception does not.

12 / 30

If you had sight in only one eye, which of the following depth cues could you NOT use?

(A) texture gradient

(B) convergence

(D) interposition

(E) shading

13 / 30

Gate-control theory refers to

(A) which sensory impulses are transmitted first from each sense.

(B) which pain messages are perceived.

(D) the gate at the optic chiasm controlling the destination hemisphere for visual information from each eye.

(E) how our minds choose to use either bottom-up or top-down processing.

14 / 30

Weber’s law determines

(A) absolute threshold.

(B) focal length of the eye.

(D) amplitude of sound waves.

(E) just-noticeable difference.

15 / 30

What is the principal difference between amplitude and frequency in the context of sound waves?

(A) Amplitude is the tone or timbre of a sound, whereas frequency is the pitch.

(B) Amplitude is detected in the cochlea, whereas frequency is detected in the auditory cortex.

(C) Amplitude is the height of the sound wave, whereas frequency is a measure of how frequently the sound waves pass a given point.

(D) Both measure qualities of sound, but frequency is a more accurate measure since it measures the shapes of the waves rather than the strength of the waves.

(E) Frequency is a measure for light waves, whereas amplitude is a measure for sound waves.

16 / 30

Smell and taste are called __________ because __________

(A) energy senses; they send impulses to the brain in the form of electric energy.

(B) chemical senses; they detect chemicals in what we taste and smell.

(E) memory senses; they both have powerful connections to memory.

17 / 30

20 / 30

Our sense of smell may be a powerful trigger for memories because

we are conditioned from birth to make strong connections between smells and events.

the nerve connecting the olfactory bulb sends impulses directly to the limbic system.

the receptors at the top of each nostril connect with the cortex.

smell is a powerful cue for encoding memories into long-term memory.

strong smells encourage us to process events deeply so they will most likely be remembered.
