6) A monkey that has previously received a lesion in the lateral prefrontal cortex is
shown two food wells, each of which is covered by a marked stimulus card:
As the monkey watches, a food reward is placed into the left well and then both wells
are covered. If the monkey is now allowed to retrieve the food reward immediately, it
will

b. patterns of activity among groups of neurons may describe the function of a brain
area better.
c.the receptive field of a single neuron changes as the brain develops.
d. single-cell recording is effective only in exploring the primary sensory cortex.
8) The implicit association test (IAT) measures the degree to which social groups are
automatically associated with positive and negative evaluations. Which of the following
is FALSE regarding this test?
a. One variant of the test examines attitudes toward different racial groups.
b. The primary measures of this test are response latencies.
c. The IAT is designed to reflect declarative memories.

indicate that this is true?
a. facial expression
b. physiological reaction
c. brief duration
d. all of the above

system from the cortical and subcortical components. Which of the following best
describes the motor abilities of this animal?
a. The dog is able to sit and roll over in response to commands.
b. The dog can move proximal effectors normally, but not distal effectors.
c. The dog demonstrates reflexive withdrawal of its foot in response to sudden
stimulation.
d. Only vital motor functions such as breathing and heartbeat are intact in this animal.
