• just noticeable difference

• absolute threshold

• extrasensory perception

• subliminal perception

Everything that we see from minute to minute—from a small pink flower to a tall granite building—is simply a function of:

• ionized chemicals

• charged particles

• compressed air

• reflected light

Younger people might take advantage of the fact that as we age we lose the ability to perceive certain frequencies by using what kind of sound for ringtones?

• other young peoples' voices

• foghorns

In which of the following parts of the ear are sound waves converted to a neural signal?

• cochlea

• oval window

• semicircular canal

The papillae play a key role in which of the following?

• vision

• kinesthesis

• olfaction

• gustation

When eating a bowl of sweet vanilla ice cream, the chemical stimuli are converted into electrical signals by the:

• taste buds

• saliva

• papillae

• olfactory bulb

Once a scent stimulus is converted to electrical signals, what is its initial destination?

• temporal lobe

• somatosensory cortex

• olfactory bulb

• olfactory epithelium

The vestibular sense utilizes bodily structures that are primarily involved with:

Touch receptors in the epidermis are most likely to be present in the:
