(35 cards)
memory required for language
phonological - sounds of words
orthographic - spelling of words
semantic - meaning of words
sensory required for language
auditory processing - spoken words or music
visual processing - written words or objects or faces
tactile processing - braille
motor required for language
articulation, writing, signing or drawing, moving hand, holding pen
individual sound units
phoneme
written form used to represent phonemes
grapheme
smallest meaningful units of a word, in combination creates words (prefixes/suffixes)
morphemes
admissable combinations of words in phrases and sentences (grammar/placement of words)
syntax
the collection of all words in a given language, mental “dictionary”
lexicon
the meanings that correspond to all lexical items and possible sentences
semantics
study of how and why words take on certain structure and how that affects semantics and syntax
morphology
social rules governing how language is used
pragmatics
vocal intonation that can modify the literal meaning of words and sentences
prosody
linking of sentences such that they constitute a narrative
discourse
disorder of language and can be apparent in speech, writing, reading or all three
produced by injury to the brain areas specialized for the functions
key thing is deficit is not due to paralysis or intellectual delay
aphasia
PAUL BROCA: language production
motor, expressive, non-fluent aphasia
difficulty speaking: slow, deliberate, simple grammar structure; melodically flat, comprehension intact, damage to left frontal (lower posterior)
fluent ability to put words together is lost
CARL WERNICKE: language comprehension
receptive, fluent aphasia
speech production intact and flows without hesitation; appropriate innotation; comprehension impaired; speech is meaningless; damage to left temporal (superior and posterior)
conduction aphasia
damage to left auditory cortex in insula
fluent speech and intact comprehension
cannot repeat words
global aphasia
massive lesion in left hemisphere
impaired production, comprehension and repetition
alexia without agraphia
normal speech, normal writing, poor reading
agraphia
normal speech, poor writing
word deafness
normal speech, poor comprehension, poor repeition
subtests of Boston Diagnostic Aphasia Exam
boston naming test: patient is required to name various pictures that vary in frequency, animacy, etc.
responsive naming: answer the object that refers to the statement like “what do we tell time with”
boston naming areas
circumlocation: anomic (tip of tongue phenomena; phonemic clues help)
perceptual error
semantic paraphasia (get meaning, wrong word, still english): Wernicke and transcortical sensory
phonemic paraphasia (semantically unrelated word that shares a lot of phenomes with real word): Wernicke and transcortical sensory
neologism: made up word that shares 50% phenomes with target word: Wernicke’s and transcortical sensory
TESTS OF EXPRESSION
oral agility: tongue and mouth movements
verbal agility: say “tip-top, tip-top”
automatic sequences: days of week, count to 10
mean length of utterance
