MULTIPLE CHOICE
The ABCs of Perception

Learning Objective- 3.1 What is sensation and how does it enter the central nervous system?

1. ______ are the raw data of experience, based on the activation of certain receptors located in the various sensory organs. a)Perceptions

Incorrect. Perception is the mental process of sorting, identifying, and arranging the raw data of experience into meaningful patterns. Sensations are the raw data of experience.

b) Emotions
c)Cognitions
d)Sensations

Correct. Sensations are the raw data of experience based on receptor activation.

ANS: d, p. 84, C, LO=3.1, (1)

2. ______ is the mental process of making sense of sensory information. a)Abstraction
b)Sensation
Incorrect. Sensation is the activation of the receptors. Perception is the mental process of making sense of sensory information. c)Perception
Correct. Perception is the mental process of making sense of sensory information. d.Consciousness

ANS: c, p. 83, C, LO=3.1, (2)

3. Activation of the receptors by stimuli is called ________. a)perception

Incorrect. Perception is the mental process of sorting, identifying, and arranging the raw data of experience into meaningful patterns. Sensation is the activation of the receptors.

b)sensation

Correct. Sensation is the activation of the receptors by stimuli.

c)adaptation
d)habituation

ANS: b, p. 84, F, LO=3.1, (1)

4. Cells that are triggered by light, vibrations, sounds, touch, or chemical substances are called ________. a) ganglion cells
Incorrect. Ganglion cells are connector neurons that come into play later in the process. They take information from receptors and related cells and then send it on for more processing. Receptors respond directly to stimuli. b) bipolar cells

c) ossicles
d) sensory receptors
Correct. Cells that are triggered by light, vibrations, sounds, touch, or chemical substances are called sensory receptors; examples are rods, cones, and hair cells.

ANS: d, p. 84, F, LO=3.1, (2)

5. The point at which a person can detect a stimulus 50 percent of the time it is presented is called the ______. a) absolute threshold
Correct. The point at which a person can detect a stimulus 50 percent of the time it is presented is called the absolute threshold. b) range threshold
c) difference threshold
Incorrect. The difference threshold is the smallest difference between two stimuli that a person can detect 50 percent of the time it is presented. d) noticeable threshold

ANS: a, p. 84, C, LO=3.1, (3) SG

6. The term just noticeable difference is synonymous with ______. a) separation threshold
b) response threshold
Incorrect. Response threshold is not a term used in the text. The term just noticeable difference is the correct synonym. c) difference threshold
Correct. The term just noticeable difference is synonymous with difference threshold and refers to the detection of change. d) absolute threshold

ANS: c, p. 84, F, LO=3.1, (2)

7. The lowest intensity of a particular stimulus that enables the average person to detect that stimulus 50 percent of the time it is presented is called the ___________. a) absolute threshold

Correct. The absolute threshold is the lowest intensity of a particular stimulus that enables the average person to consciously detect that stimulus 50 percent of the time it is presented. b) difference threshold

c) just noticeable difference
d) psychophysical threshold
Incorrect. There is no such term as psychophysical threshold.

ANS: a, p. 85, F, LO=3.1, (2)

8. The smallest amount of a particular stimulus required to produce any sensation at all in the...
