Word retrieval following mild TBI:
Implications for categorical deficits.
Aphasiology, 20, 235-245.
(purpose)
The purpose of this study was to
measure response time and accuracy
of noun and verb retrieval in patients
with mild TBI. The authors hoped to
shed light on how lexical processing
takes place in brains with diffuse
injury as opposed to brains with
defined lesions.
(method)
The researchers tested two groups of 10,
one group with no brain injury, and one with
mild TBI. The groups were matched for age,
gender, and education. The Test of
Adolescent/ Adult Word Finding was used to
measure picture naming for nouns, sentence
completion, description naming, picture
naming for verbs, and category naming.
Participants were measured according to
accuracy and response time.
(results)
The researchers found no significant
differences in accuracy of word
retrieval between the MTBI group and
the NBD group. However, the NBD
group was faster on tasks. The MTBI
group also named living items more
accurately than they named non-living
items.
(discussion)
The varied results of this study
reinforce previous studies which have
found a complex and distributed
network for processing nouns and
verbs. The authors noted that more
research is necessary to fully
understand the multiple levels of
difficulty in word retrieval
characteristic of brain injured patients.
