Ch. 15: Brain Asymmetry, Spatial Cognition and Language

Ken underwent a neuropsychological test where he put on a sleeping mask and was asked to identify objects by touch alone. He did not do very well and his doctor indicated that Ken may have:

Astereognosis

If Reverend Spooner had described his typical language transpositions to someone, he might have said they were just "tips of the slung". This is an example of Wernicke's aphasia.

False, (Wernicke's aphasia is difficulty producing language that makes sense. The Reverend Spooner could speak normally but often misspoke in paraphasias, or slips of the tongue, where he substituted or transposed sounds for similar sounds or whole words.)

"Split-brain" patients is the term given to people who:

Have had their corpus callosum severed

In both humans and nonhuman primates, the part of the brain in the left hemisphere that is larger than on the right is called:

Planum temporale

After a brain injury that damaged her fusiform gyri bilaterally, Suzette could no longer:

Recognizes faces, even her own

Due to a stroke, Mrs. Simpson now makes no sense when she talks though she has no problem forming words. Mrs. Simpson would be diagnosed with:

Wernicke's aphasia

Phonemes are the

basic sounds of a language.

Stories of children who were not taught language before the age of 12 and had difficulty learning to speak after that demonstrate that we must learn language as a child or the brain cannot wire itself appropriately. This shows that we have a(n) ________________ period for learning language.

critical

In nonhuman primates, the brain regions in which electrical stimulation elicits vocalizations seem to be those also involved in

defense, attack, feeding, and sex behaviors.

The brain imaging technology that allows researchers to see the axonal connections between brain regions is called ____________________________.

diffusion tensor imaging

Hemispheric specialization is also known as

lateralization.

The _______ hemisphere plays a major role in the perception of language. The _______ hemisphere plays a major role in prosody.

left; right

Wernicke's aphasia is usually associated with lesions of

the left posterior temporal region.
