Flashcards in 14.2 Evolution and Physiology of Language Deck (11):
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
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
Characterized by mental retardation in most regards, but skillful use of language
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
Severe language impairment
A small part of the frontal lobe of the left cerebral cortex knew the motor cortex
Nonfluent aphasia; characterized most prominently by impaired language production
Located near the auditory part of the cerebral cortex
Characterized by impaired ability to remember the names of objects and impaired language comprehension; fluent aphasia
Difficulty recalling the names of objects
