Which statement about language lateralization in monkeys is true?
Similar to humans, monkeys show a preference for using the right ear (which has connects to the contralateral side) to listen to vocalizations of conspecifics.
Which statement best illustrates the motor theory of language?
When we listen to speech, we process the speech sounds using the same neural systems that we use to make those sounds.
Disturbance in reading is called
alexia.
Apraxia is
an inability to execute a learned sequence of movements.
Damage to the _______, which transmits information between Wernicke's area and Broca's area leads to _______ aphasia.
arcuate fasciculus; conduction
Diffusion tensor imaging (DTI) findings
are inconsistent with the connectionist model of aphasia.
In most split-brain patients, words presented to the left visual field
cannot be repeated verbally.
According to some studies, stroke patients given _______ therapy can show about a 75% return of normal use of a paralyzed arm within a relatively short period of time.
constraint-induced movement
The human brain shows a clear _______, during which exposure and practice with language must occur in order for language skills to develop normally.
critical period
Unusual groupings of cells in the outer layers of the cerebral cortex have been seen in postmortem studies of
dyslexia.
An exciting, but controversial future treatment for brain injury may be the use of _______ to replace the damaged neurons in the brain and spinal cord.
embryonic stem cells
The complete loss of the ability to understand language, or to speak, read, or write is called _______ aphasia.
global
If conscious subjects receive transcranial magnetic stimulation (TMS) of anterior portions of Broca's area, they
have difficulty understanding the meanings of words.
In infants, the left planum temporale is larger than the right, suggesting that
humans have an inborn neural mechanism for language.
Hemispheric specialization is also known as
lateralization.
Aphasic patients may produce nonsensical or meaningless words called
neologisms.
The sounds that make up a language are called _______, and the system of rules for producing sentences is called _______.

right; right
Anna has been diagnosed with deep dyslexia. The most obvious symptom she has is
she interprets a word when reading not as the word on the page but as a semantically related word.
In nonhuman primates, the brain regions in which electrical stimulation elicits vocalizations seem to be those involved in
strongly emotional behaviors, such as defense, attack, feeding, and sex behaviors.
In monkeys, stimulation of the _______, but not of the _______, results in vocalizations.
subcortical regions; cortex
Early studies using electrodes to stimulate discrete areas of cortex, thereby disrupting neural function, found
that electrical stimulation interfered with language abilities.
Williams syndrome provides evidence for
the heritability of language.
Wernicke's aphasia is usually associated with lesions of
the left posterior temporal region.
