Abstract:
Abstract: The purpose of this study was to examine an
acquired dyslexia patient's (BV) ability to read aloud regular
nonwords (e.g., FRIP), pseudohomophonic nonwords (e.g., HEET), and
words. BV was grossly impaired at reading aloud regular nonwords
(she did not correctly pronounce any of these items), but correctly
read aloud 40% of pseudohomophonic nonwords. In addition, BV
invariably gave words as responses to the nonwords, even though she
understood that the task was to pronounce nonwords. Further, most
of the words she gave as responses to the nonwords shared the first
several letters with the nonwords. A similar pattern of errors was
observed when BV read aloud words, in that over 75% of these errors
shared the first several letters with the target words. It is clear
that BV used some form of nonlexical phonological processing to
obtain pronunciation for nonwords such as HEET. Moreover, because
she was much better at pronouncing pseudohomophonic nonwords than
regular nonwords it is clear that some lexical involvement also
occurred. We explain BV's pattern of error results in terms of
competition between lexical and nonlexical phonological processing
within the dual-route framework.
