Language Flashcards
Aphasia
A disorder in language processing. Can be expressive (impaired language production) or receptive (impaired language composition)
Anomic Aphasia
Word retrieval failure
Wernicke’s Aphasia
Can’t understand spoken/written language
Broca’s Aphasia
Can’t understand spoken/written language
Pure word deafness patients can’t understand spoken words but can…
Read, write, speak normally, recognise non-speech sounds and different emotions in speech
PWD caused by damage to…
Bilateral superior temporal lobe
PWD due to damage in the…
Auditory input lexicon or the acoustic analysis module
PWD cannot rapidly put together a string of speech sounds into individual phonemes so the deficit is in…
Rapid temporal processing used to make sense of speech input and identify phonemes
Pure Word Meaning Deafness is…
Inability to understand words
PWMD- Damage is in the…
Auditory input lexicon and the semantic system. They are disconnected
Semantic Anomia
Problems finding words bc there is a semantic disturbance. Faulty semantic memory system
Phonological Anomia- defect lies in the…
Phonological output lexicon (deals with word articulation)
Prosody
Pattern of intonation accompanying speech, communicates emotion
Right Hemisphere damage causes=
Impaired ability to understand prosody or use it (Blonders et al. 1991)
Beaucousin et al., (2006) found from fMRI…
Right sided activation of anterior superior temporal sulcus & posterior superior temporal gyrus
Burgess and Simpson found (river/money bank)…
Subordinate meaning is inhibited by the LH and RH maintains both
RH patients cannot…
build global representations of language or properly follow a thread of conversation
RH patients find it difficult to…
process non-literal info
Metaphor processing is controlled by…
LH and RH, not just RH
Semantic activation controlled by…
Posterior middle/superior temporal gyri
Semantic integration controlled by…
Anterior middle/superior temporal gyri
Semantic selection controlled by…
Inferior frontal gyrus
Wise et al. (1996) found with non speech sounds and speech sounds that…
Activation in the superior temporal gyrus and sulcus may show word processing in this area
Semantic tasks trigger activation in…
The left pre-frontal cortex
