Under the influence of serial two-stage models of lexical retrieval
(e.g., Levelt, 1989), treatments for naming deficits in aphasia have been
of two broad types: semantic and phonological. Semantic treatments
focus on highlighting the meaning of the word and phonological
treatments focus on emphasizing the form of the word in the absence
of its meaning. Both semantic and phonological treatments for anomia
have been found to be effective (e.g., Coelho, McHugh, & Boyle, 2000;
Wambaugh, 2003). Recently, another form based treatment for
anomia—orthographic cueing—has proven effective in some instances.
For example, Hickin, Best, Herbert, Howard, and Osborne (2002)
showed that phonological and orthographic treatment improved
naming performance in seven patients, and DeDe, Parris, and Waters
(2003) showed improved naming in one patient with both orthographic
and tactile cues.
We present the case of an individual with anomia who was initially
enrolled in a combined semantic and phonological features analysis
treatment that was then modified to include orthographic cueing.
Method
Subject
M.H. was a 75-year-old, right-handed man, who suffered a single
left hemisphere stroke and was 2 years post-onset at the time of testing.
Results on the BDAE were consistent with the profile of mixed non-
fluent aphasia. Pre-therapy tests identified a significant naming im-
pairment (7% correct on the Philadelphia Naming Test) with relatively
spared repetition (90% correct) and oral reading (93% correct) skills,
but impaired single word comprehension (51% correct).
Design
A multiple-baseline across behaviours design was used. Initially, as
part of a larger study (Rochon & Leonard, in preparation), M.H. was
assigned to a combined semantic and phonological features treatment
condition. To obtain a list of words to be treated and ensure a stable
baseline, M.H. was first shown 105 pictures and asked to name them in
three consecutive sessions. Of the words that were in error in each
session, M.H. was asked to choose the items that he would like to have
treated. Of those words, 30 were chosen and divided into three lists of
10 words each. The three lists were equated as much as possible by
category, frequency, and number of syllables. List 1 words were treated
first while words in Lists 2 and 3 were held in baseline. Treated words
were probed every second session and untreated every third session,
prior to the beginning of treatment. The criterion for moving to
treatment on a subsequent list was 80% correct or a maximum of 15
sessions.
Treatments and results
Combined semantic and phonological
This treatment involved the use of a features analysis chart fol-
lowing the protocol of Coelho et al. (2000). The target picture was
presented in the centre of the chart and M.H. was asked to name it.
Irrespective of his ability to do so, he was asked to identify three se-
mantic features (group, associations, and properties) and two phono-
logical features (rhymes, first sound). If M.H. could not spontaneously
provide a response he was asked to choose one from a list of four. The
examiner wrote the word on the chart. Once all features were gener-
ated, M.H. was asked to name the target again and all features were
reviewed. This treatment proved unsuccessful as M.H. achieved only
20% correct on Lists 1 and 2 and 10% correct on List 3.
Phonological features
Three new treatment lists of 10 items each were constructed
from the list of pictures that M.H. could not name. The protocol
was the same as that used above with the exception that only
phonological features (rhymes, first sound, first sound associates,
final sound, and number of syllables) were targeted. Treatment of
List 1 was unsuccessful, therefore this therapy was terminated and
the orthographic cueing procedure described below was initiated on
List 2.
Orthographic cueing
Despite M.H.’s significant naming impairment, an interesting
component of his linguistic competence was his ability to complete
crossword puzzles. We used this strength in a modification of the
features treatment just described. In this approach, M.H. was required
to write the first letter in the target word. If M.H. could not sponta-
neously provide a response, the examiner wrote the letter. M.H. (or the
examiner) provided successive orthographic cues until he could name
the word or until the word was written in its entirety. This treatment
proved successful as percent correct on items in List 2 increased from
10 to 80 over the course of 14 sessions (see Fig. 1), while performance
on untreated items (Lists 1 and 3) remained virtually unchanged (all at

0% correct except for the first probe of List 1 items which was at 10%
correct). Treatment on List 3 items was begun, but terminated early
due to time constraints, leaving the results inconclusive.
Follow-up testing 2 weeks post-therapy revealed that the effects of
treatment for List 2 were not maintained (10% correct).
Discussion
The present results highlight the potential benefits of orthographic
cueing to improving naming deficits in aphasia and underscore the
importance of capitalizing on a patient’s strengths when designing
therapy. While these results are encouraging, they are considered
preliminary in the sense that only one list of items and only one
patient were treated. Additionally, the effect proved to be of short
duration and potential contributing factors to this finding must be
considered.
