Visual to auditory silent matching task in adults who do and do not stutter
MetadataShow full item record
The purpose of the present study was to investigate the role of phonological working memory in adults who do and do not stutter through a visual to auditory silent matching task. This task also explored the possible relationship between auditory processing and its ability to affect performance on the task. Participants were 13 adults who stutter (mean age = 28 years), matched in age, gender, handedness, and education level with 13 adults who do not stutter (mean age = 28 years). For the nonvocal visual to auditory task, participants silently read an initial target nonword and matched that target nonword to four subsequent auditory nonword choices. The participants completed this task for 4- syllable and 7- syllable nonwords (N = 8 per set). Results indicated that adults who stutter were significantly less accurate than adults who do not stutter at both syllable lengths. Our present findings support previous research that suggests less efficient phonological working memory in adults who stutter.
