Patients with lesions in the dorsolateral prefrontal cortex are most likely to exhibit: A. acquired sociopathy. B. perseverative responses. C. decreased initiative and motivation. D. behavioral disinhibition.
B. perseverative responses.
A patient with severe hemiplegia caused by a lesion in the right side of her brain denies she has any problems moving her left arm and leg. This woman’s lack of awareness of her physical impairment is referred to as:
anosognosia.
A picture of a knife is projected onto a screen so that it’s briefly presented only to the right visual field of a split-brain patient, and a picture of a fork is then briefly presented only to the patient’s left visual field. When asked to verbally identify what he has seen, the patient:
A. will be able to say “knife” and, although he can’t say “fork,” will be able to pick out a fork with his left hand.
B. will be able to say “fork” and, although he can’t say “knife,” will be able to pick out a knife with his right hand.
C. will be able to say “knife” but won’t be able to say “fork” or pick out a fork with his right or left hand.
D. will be able to say “fork” but won’t be able to say “knife” or pick out a knife with his right or left hand.
A. will be able to say “knife” and, although he can’t say “fork,” will be able to pick out a fork with his left hand.
Damage to Broca’s area produces:
nonfluent speech with intact comprehension

Ideomotor apraxia is usually caused by damage to:
the left (dominant) parietal lobe.
The word COPYCAT is presented to a split-brain patient so that COPY is projected to the patient’s left visual field and CAT is projected to his right visual field. When the patient is asked what he saw, the patient will say ________. And when the patient is asked to use his left hand to point to what he saw on a computer screen that contains the words COPY and CAT, the patient will point to ________.
CAT; COPY
