Chapter 3: Sensation and Perception
1. What is sensation?
a. The process of interpreting sensory information
b. The process of detecting and encoding sensory information
c. The process of organizing sensory information into meaningful patterns
Answer: b. The process of detecting and encoding sensory information
Explanation: Sensation refers to the process of detecting and encoding
sensory information from the environment.
2. What is perception?
a. The process of interpreting sensory information
b. The process of detecting and encoding sensory information
c. The process of organizing sensory information into meaningful patterns
Answer: a. The process of interpreting sensory information
Explanation: Perception refers to the process of interpreting and making
sense of sensory information.
3. What is the absolute threshold?
a. The smallest amount of stimulation needed to detect a sensory input
b. The difference threshold between two stimuli
c. The maximum level of stimulation that a sensory system can handle
Answer: a. The smallest amount of stimulation needed to detect a sensory
input
Explanation: The absolute threshold is the smallest amount of stimulation
needed for a person to detect a sensory input.
4. What is the difference threshold?
a. The smallest amount of stimulation needed to detect a sensory input
b. The difference between the absolute threshold and the maximum
threshold
c. The smallest difference between two stimuli that can be detected
Answer: c. The smallest difference between two stimuli that can be detected
, Explanation: The difference threshold, also known as the just noticeable
difference, is the smallest difference between two stimuli that can be
detected by a person.
5. What is sensory adaptation?
a. The process by which sensory information is encoded and transmitted to
the brain
b. The process by which sensory information is organized into meaningful
patterns
c. The process by which sensory receptors become less sensitive to constant
or repetitive stimulation
Answer: c. The process by which sensory receptors become less sensitive to
constant or repetitive stimulation
Explanation: Sensory adaptation is the process by which sensory receptors
become less sensitive to constant or repetitive stimulation, allowing us to
focus on important changes in the environment.
6. What is the difference between rods and cones in the eye?
a. Rods are responsible for color vision and cones are responsible for black
and white vision
b. Rods are responsible for black and white vision and cones are responsible
for color vision
c. Rods and cones are both responsible for color vision
Answer: b. Rods are responsible for black and white vision and cones are
responsible for color vision
Explanation: Rods are responsible for detecting light and dark, or black and
white, while cones are responsible for color vision.
7. What is the function of the cochlea in the ear?
a. To detect sound waves and transmit them to the brain
b. To detect changes in head position and movement
c. To detect changes in body temperature and regulate heat loss
Answer: a. To detect sound waves and transmit them to the brain
Explanation: The cochlea is a spiral-shaped structure in the ear that is
responsible for detecting sound waves and transmitting them to the brain.
