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 feature of birdsong suggests it is analogous to human speech?
Some birds require early exposure to species-typical birdsong in order to develop their characteristic song.

prosopagnosia
People with conduction aphasia are unable to
repeat words or sentences.
The goal of constraint-induced movement therapy is to encourage stroke patients to use the afflicted arm by _______ the unaffected arm.
restraining
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.
Mirror therapy has been shown to be useful for rehabilitation after brain injury as it
tricks the brain into thinking they are moving the paralyzed arm.
A patient who has difficulty speaking but has good comprehension of verbal material is most likely suffering from _______ aphasia.
Broca's
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.
The relationship between the direction of the whorl of hair on the top of the head and handedness supports the idea that
a single gene has a major influence on asymmetry throughout the body.
If conscious subjects receive transcranial magnetic stimulation (TMS) of anterior portions of Broca's area, they
have difficulty understanding the meanings of words.
TMS brain mapping has shown that _______ regions of Broca's area are important for _______ processing.
posterior; phonological
Under which circumstance would a doctor request that a patient undergo a Wada test?
If a patient may need to undergo neurosurgery
Disturbance in reading is called
alexia
Hemispheric specialization is also known as
lateralization
Children show evidence of sensitivity to the "rules" of language by the age of _______ months.

Which statement about childhood aphasia true?
Language abilities impaired by childhood brain injury are usually restored by adulthood.
_______ is an anatomical abnormality of developmental dyslexia that is associated with excessive cortical folding in areas such as the temporoparietal junction.
Micropolygyria
In ERP studies of normal subjects, it has been found that a grammatically correct sentence containing a word whose meaning does not fit into the sentence provokes a(n) _______ wave from _______ cortex.
N400; temporoparietal
Diffusion tensor imaging (DTI) findings
are inconsistent with the connectionist model of aphasia.
In boxers, the devastating effects of repeated blows to the head are evident in the development of a progressive cognitive impairment called
chronic traumatic encephalopathy.
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.
