Psychology: Chapter 2 Study Guide
Question 1
In a resting state, the axon is
polarized, with mostly positively charged ions outside and negatively charged ions inside. Question 2
In the brain, learning occurs as experience strengthens certain connections in cell work groups called
neural networks. Question 3
When the effect of one factor (such as environment) depends on another (such as heredity), we say there is a(n) ________ between the two factors.
interaction Question 4
Chromosomes are composed of a coiled chain of
DNA molecules that contain genes. Question 5
The increasing complexity of animals' behavior is accompanied by an
increase in the amount of association area. Question 6
Voluntary movements, such as writing with a pencil, are directed by the
somatic nervous system. Question 7
Cortical areas that are NOT primarily concerned with sensory, motor, or language functions are
called association areas. Question 8
An experimenter flashes the word FLYTRAP onto a screen facing a split-brain patient so that FLY projects to her right hemisphere and TRAP to her left hemisphere. When asked what she saw, the patient will
say she saw TRAP. Question 9
A strong stimulus can increase the
number of times the neuron fires. Question 10
Following a head injury, a person has ongoing difficulties staying awake. Most likely, the damage occurred to the
reticular formation. orrect!
Question 11
A neuron will generate action potentials when it receives more excitatory than inhibitory inputs. Question 12
Dr. Hernandez is studying neurotransmitter abnormalities in depressed patients. She would most likely consider herself be a ________ psychologist.
biological Question 13
Heartbeat, digestion, and other self-regulating bodily functions are governed by the
autonomic nervous system. Question 14
The axons of certain neurons are covered by a layer of fatty tissue that helps speed neural transmission. This tissue is
