Post-Treatment Results for /s/ Clusters: /sp, sm, sn, st, sw/. Post-treatment data<br />

were collected after a 2 week-break from treatment. Data were gathered at CP’s residence<br />

due to PSU clinic closures for spring break. Figure 1 illustrates the generalizati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

trained <strong>speech</strong> sounds to untrained words in the c<strong>on</strong>text <str<strong>on</strong>g>of</str<strong>on</strong>g> phrases. Post treatment results<br />

show that CP’s producti<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> /s/ c<strong>on</strong>s<strong>on</strong>ant clusters remained stable following a 16-day<br />

cessati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> treatment for those sounds. Over the last 9 sessi<strong>on</strong>s <str<strong>on</strong>g>of</str<strong>on</strong>g> treatment, CP’s<br />

percent accuracy correct <str<strong>on</strong>g>of</str<strong>on</strong>g> /s/ c<strong>on</strong>s<strong>on</strong>ant clusters achieved a pattern <str<strong>on</strong>g>of</str<strong>on</strong>g> stability<br />

alternating between 80% and 100%. Results from post-treatment probes over 3 sessi<strong>on</strong>s<br />

did not diverge from that trend, staying within the 80% to 100% range <str<strong>on</strong>g>of</str<strong>on</strong>g> accuracy,<br />

suggesting that motor learning had occurred.<br />
