Specifically this report focuses on the effects of LBI on vocabulary skills (e.g. naming and defining). Nineteen ELLs (ages 74 to 104 months) participated in the intervention study, which lasted eight weeks and consisted of 50-minute sessions, three times a week. The LBI focused on rich vocabulary instruction of words that were from storybook readings. Vocabulary naming and definition probes were used to assess vocabulary progress. Results revealed that vocabulary increases did not occur until the second half of the intervention (e.g. week six or seven). LBI shows promise to be successful for increasing vocabulary skills in ELLs with SLI.Item Convergence of two language assessment measures with ability in school-age Spanish-English bilingual children(2011-05) Johnston, Lia Marie; Bedore, Lisa M.; Bedore, Lisa M.; Pena, Elizabeth D.There is a documented need for appropriate language assessment measures for Spanish-English bilingual school-age children in the United States. The Bilingual English Spanish Assessment- Middle Extension (BESA-ME), the Test of Narrative Language (TNL), and the Test of Narrative Language- Spanish experimental version (Spanish TNL) were administered to 129 children ranging in age from 7;0 to 8;11. Convergence between the measures was examined. The results indicated a strong correlation between measures, as well as significant correlation between each measure and children’s ability level (i.e. classification as typically developing or with language impairment). These results present the BESA-ME and the TNL in Spanish and English as promising tools to assess language impairment in a population that traditionally has been a challenge to evaluate.Item Diagnostic accuracy in motor speech disorders: an application of signal detection theory(Texas Tech University, 2004-05) Whitaker, Melissa C.; Bogschutz, Renee J.; Schmitt, Mary B.; Aoyama, Kastura; Corwin, Melinda D.The results of this study indicated that participants accurately and reliably differentiated normal from abnormal speech samples. Thus, all groups proficiently identified disordered cases while limiting the number of misdiagnoses; however, some degree of task difficulty was noted and clinical biases were evident. For this research question, group trends indicated that the most experienced group of participants adopted a more lenient diagnostic criterion as compared to the intermediate and novice groups.Item Distribution of stutterings among speech acts(Texas Tech University, 1989-05) Corwin, Melinda D.The purpose of this study was to describe the distribution of stutterings among speech acts. Ten adult stutterers engaged in conversational tasks designed to naturally encourage production of Representatives, Expressives, Commissives, Directives, and Questions. The total number of speech acts (i.e., utterances) containing stuttered speech was determined, as was the total number of stuttered words within each speech act. A nonparametric statistic was used to test for significance. Results indicated that, as a group, stutterings were distributed equally among speech acts, although the performance of some subjects suggests a clinically relevant speech act-stuttering connection.Item The effect of phonological, semantic, and hybrid associates on accurate recall and false memories of adults who stutter : a preliminary study(2011-05) Delahoussaye, Amy Leigh; Byrd, Courtney T.; Sheng, LiThere are data to suggest that the phonological representations of young children who stutter are less specified than their typically fluent peers. The purpose of the present study is to determine if this apparent difference in phonological encoding persists in adults who stutter. Utilizing a false memory paradigm, nine adults who stutter (AWS) were asked to listen to and then recall/produce 12 lists of 12 words each. Each word list was comprised of either semantic, phonological or an equal number of semantic and phonological associates of a single, unpresented, critical ‘lure’ word. Three parameters of recall performance were measured across these three conditions: 1) number of accurately recalled productions, 2) number of lure intrusions and 3) number of other intrusions. AWS produced significantly more accurate recalls in the semantic condition than either the hybrid or phonological conditions, and significantly more lure intrusions in the phonological and hybrid conditions than the semantic condition, but there was no significant difference on measures of other intrusions. These results extend the findings with young children who stutter, and indicate that the phonological representations are less robust than the semantic representations in the lexicon of AWS.Item Factors which parents of functionally speech defective children have in common(Texas Tech University, 1965-08) Turner, Jo EllaNot availableItem Frontal-lobe mediated word retrieval in Parkinson's disease(Texas Tech University, 1996-12) Thomason, Christine K.Parkinsonians have been shown to have difficulty with executive functioning, which is mediated by the frontal lobes of the brain. Tests of verbal fluency have been used to evaluate frontal lobe dysfunction. Letter fluency, however, may require different processes and mechanisms than semantic fluency. Martin and colleagues (1994) found that letter fluency seemed to be mediated by the frontal lobes whereas semantic fluency seemed to be mediated by the temporal lobes. It follows that Parkinsonians would have difficulty with letter fluency tasks, given their problems with frontal lobe functions. Differences between 30 Parkinsonian patients and 30 age-matched controls on both semantic and letter fluency tasks were examined and the relationship of performance on these tasks to executive function was evaluated. Results indicated that when executive functioning and depression are accounted for. Parkinsonians demonstrated poorer performance on letter but not category fluency relative to controls. Before accounting for depression and executive functioning, there were no differences between groups on letter fluency, however, controls performed significantly better than Parkinsonians on category fluency. Both category and letter fluency tasks correlated highly with a measure of executive function, the EXIT, but only for Parkinsonians. Screening for both executive impairment and depression are important when examining cognitive function in Parkinson's disease.Item The identification of stuttering in bilingual children(2011-05) Mullis, Anna Katherine; Byrd, Courtney T.; Bedore, Lisa M.The purpose of the present study was to examine, based on audio samples in both languages, the accuracy of diagnosis of the presence or absence of stuttering in a bilingual Spanish English (SE) child who may or may not stutter by bilingual SE speech- language pathologists (SLPs) living in Texas (n=14). This study also aimed to determine what speech characteristics (if any) influenced SLPs’ judgment of whether or not a bilingual SE child was a stutterer, as well as to explore whether personal characteristics of the bilingual SLPs who completed the ratings (i.e., years experience, confidence in diagnosing an SE child with stuttering, educational history on the topics of stuttering and/or bilingualism) uniquely impacted the accuracy of their diagnosis. Information gained from this study suggests that the atypically frequent (in comparison to monolingual children) word and phrases repetitions produced by bilingual SE children who do not stutter may put this population at risk for misdiagnosis of stuttering. Results also indicate that the accuracy of identification of a bilingual SE child who does not stutter is not influenced by any of the personal characteristics listed above. Rather, there seems to be an overall lack of knowledge regarding the speech disfluencies that differentiate bilingual SE children who do and do not stutter. Thus, the preliminary data from this investigation warrants a follow-up study of the same nature on a nationwide scale.Item Investigation of the awareness and perceptions of stuttering and the resulting effect on social preference in children who do and do not stutter(2011-05) Hunt, Stephanie Lynn; Byrd, Courtney T.; Hampton, ElizabethThe purpose of this study was to examine the awareness, perception and social preference of stuttering in children who do and do not stutter. Ten children who stutter and eleven children who do not stutter participated in this study. Each participant viewed a short DVD clip of two puppets taking turns talking. One puppet produced stuttering-like disfluencies, and the other produced typically fluent speech. The participants were then asked a series of questions formulated to examine awareness, perception, and social preference. Results indicated no significant differences between the children who stutter versus the children who do not stutter on any of the three factors examined. However, within the group of children who stutter, significant differences were discovered for two of the seven questions (“which puppet talks like you?” and “what do you call this type of talking?”) when time since onset of stuttering was considered, suggesting that the longer the child has been stuttering, the greater the awareness the child has of his/her disfluent speech both in terms of the behavior and the specific terminology used to describe the behavior.
