1. What is the basic definition of transduction?

a. It is when a sensory receptor picks up a stimulus. b. It is when a sensed stimulus gets converted into an action potential in a neuron. c. It is when a sensation gets extinguished over time. d. It is when a nerve sends a signal to another nerve.

Answer: b. Transduction is when a sensed stimulus gets converted into an action potential in a neuron.

2. What does the sensation of nociception detect?

a. Pain b. Body position c. Movement d. Balance

Answer: a. The sensation of nociception is the detection of pain. There are specific nociceptors that pick up painful stimuli.

3. What is not a psychological factor that affects perception?

a. Motivation b. Stimulus intensity c. Attention d. Past experiences

Answer: b. Perception can be based on many different psychological factors, including motivation, attention, and past experiences. Stimulus intensity is a physical factor.

4. What is the distance of a wave from one peak to another peak called?

a. Amplitude b. Frequency c. Wavelength d. Crest

Answer: c. The wavelength of a wave is the distance of the wave from one peak to another peak. Waves that are of a slow wavelength are sound waves, while waves that are of a fast wavelength are visual waves.

5. What aspect of a sound wave is best determined to be measured in decibels?

a. Propagation b. Amplitude c. Wavelength d. Frequency

Answer: b. The amplitude of the sound wave can be determined in decibels. It is a measurement of the loudness of a given sound.

6. What structure of the eye is the colored part?

a. Cornea b. Retina c. Lens d. Iris

Answer: d. The auricle is the outer cartilaginous part of the ear, which is the part of the ear that can be seen on the outside.

8. What part of the inner ear is most responsible for the perception of sound?

a. Cochlea b. Semicircular canals c. Stapes d. Tympanic membrane

Answer: a. The cochlea is shaped like a snail. It is the part of the inner ear that contains the hair cells that pick up the sound waves in order to detect sound.

9. Which sense is referred to as a chemically-based sense?

a. Vision b. Nociception c. Olfaction d. Kinesthetic sense

Answer: c. Both olfaction and taste are considered chemically-based senses because chemicals change the receptor cells in order to detect these senses by the brain.

10. Which skin sensation is picked up through free nerve endings rather than through a receptor?

a. Pressure b. Vibration c. Light touch d. Pain

Answer: d. Each of these has special receptors that do the detecting of the specific sense. The only exceptions are the sensations of pain and temperature.
