Human Communication Flashcards
Communication
information transformed between individuals
Language
the most sophisticated form of communication. A set of arbitrary sounds, tokens, or symbols that convey information or concepts
Two main components of language
production and comprehension
Language lateralization: Where is verbal behavior mostly?
In the left hemisphere
Lang Lat.: what hemispheres hear and understand incoming information?
Both hemispheres
What percent of right handed people are left-hemisphere dominated for speech?
92%
Verbal behavior is
a lateralized function
Language disturbances occur after damage to what side of the brain?
Left
Components of language production
Conceptualization, formulation, articulation, and self-monitoring
What do we use to recognize the incoming information?
visual and auditory systems
Brocca’s work
Speech production
Wernicke’s work
language comprehension, conduction aphasia
Wernicke-Gershwin model
Early model for understanding how speech is produced in humans
7 components of the Wernicke-gershwin model
primary vistal cortex, angular gyrus, primary auditory cortex, wernicke’s area, brocca’s area, and the primary motor cortex
prosody
Patterns of stress and intonations used in speech.
illustrated by punctuation when writing
Prosodic disruption can occur in language disorders
Voice recognition
elements of someone’s voice can help us with recognizing who someone is and guess their age
Phoagnosia
Difficulty recognizing voices; usually the result of very focal damage in the right hemisphere
Aphasia
A disturbance in comprehension r production of language
Broca’s aphasia
caused by damage to the broca’s area
2) A disorder of speech production
3)better language comprehension than production
4) people use few function words(a, the, in, etc.), mainly content words (nouns, verbs, adjectives)
Broca’s aphasia comes with three major deficits
Agrammatism, anomia, and apraxia
Agrammatism
difficulty with basic grammar and syntax
Anomia
inability to retrieve known words; trouble with naming objects
Apraxia
Impairment in ability to program movements to produce speech
Wernicke’s aphasia
a fluent aphasia caused by damage to the Wernicke’s area
2)deficits in spoken word recognition
3)poor language comprehension-can’t grasp meaning of words/sentences
4) speech is fluid and unlabored, but meaningless
