Week 4: Naming and Word Retrieval Flashcards
naming/lexical retrieval is universally impaired in personals dx with ___________.
aphasia
in dysphagia patients, naming/lexical impairments are…
common across types
persistent across recovery
highly variable person to person
may be the “only” impairment
anomia
impairment in naming
naming is often assessed in confrontation naming tasks which are _______ naming and _________ naming.
picture naming
object naming
lexical retrieval/naming is a complex system which allows __________ to trigger ___________.
input; output
what does “input triggers output” mean in regard to lexical retrieval/naming?
modality-specific input mechanisms will register with the patient’s internal representations for familiar, learned, spoken and written words, viewed objects/people.
how they are being asked (input) will determine how they can answer (output).
semantic stage is
input mechanisms
phonological stage is
lexical output
confrontation naming with pictures:
input =
output =
visual object recognition system
lexical phonological output system
written word:
input mech =
output mech =
written lingustic recognition system
lexical orthographic output system
anomia is common to ___________ aphasia
most (if not all)
anomia is believed to be mediated by
a diffuse left-hemisphere neural network
anomia may follow ___________ and ______________ lesions
perisylvian and extrasylvian
studies of people with aphasia highlight the following regions in lexical processing:
L-temporal
L-inferior parietal
L-posterior frontal
L-thalamus
antonucci et al (2008) claims that:
left-interior temporal for semantic (lexical input) aspects of naming; injury to this area = anomia.
