Flashcards in 14.2 Evolution and Physiology of Language Deck (11):
1

Did we evolve the ability for language out of nothing or from some precursor already present in other species?

Research suggests that we evolve language from some precursor present in bonobos

2

Why didn't other animals develop language?

Two theories include (1) we evolved language as a byproduct of the overall brain development and (2) we evolved it as an extra part of the brain

3

Williams syndrome

Characterized by mental retardation in most regards, but skillful use of language

4

Poverty of the stimulus argument

Children do not hear many examples of some of the grammatical structures aquire, and therefore they could not learn them

5

Aphasia

Severe language impairment

6

Broca's area

A small part of the frontal lobe of the left cerebral cortex knew the motor cortex

7

Broca's aphasia

Nonfluent aphasia; characterized most prominently by impaired language production

8

Wernicke's area

Located near the auditory part of the cerebral cortex

9

Wernicke's aphasia

Characterized by impaired ability to remember the names of objects and impaired language comprehension; fluent aphasia

10

Anomia

Difficulty recalling the names of objects

11

Productivity

The ability to produce new signals to represent new ideas
