Effects of Speech Rate on Self-Monitoring and Lexical Error Frequency In Mothers with the FMR1 Premutation
Abstract
The FMR1 premutation occurs in 1:151 women. Women with the FMR1 premutation show very subtle signs of slight executive dysfunction, disproving the preceding belief that these individuals were only silent carriers. For this project, 32 women with the FMR1 premutation were given the “Network Production Task.” Each participant was shown 8 different networks of colored images and pictures with lines connecting them and asked asked to describe the path a red dot took within each network, being as descriptive as possible. Each network was shown twice, once at a slow speed of 27 seconds and once at a fast speed of 18 seconds. Errors were later coded into 14 different categories. This part of the project focused on the 7 lexical error categories. Based off of our statistical analysis, the superordinate and coordinate lexical errors were significantly more frequent in the fast condition. The phonemic errors also appeared to be significantly more frequent in the fast trial than the slow trial, though occurring at a low frequency. Future studies should include comparison with a control group so that we can make conclusions regarding whether the language production features observed in this sample of Fragile X carriers were atypical.
