Adverbial clauses are grammatical constructions that are of relevance in both typical language development and impaired language development. In recent years, computer software has been used to assist in the automated analysis of clinical language samples. This software has attempted to accurately identify adverbial clauses with limited success. The present study investigated the accuracy of software for the automated identification of adverbial clauses. Two separate collections of language samples were used. One collection included 10 children with language impairment, with ages ranging from 7;6 to 11;1 (years;months), 10 age-matched peers,and 10 language-matched peers. A second collection contained 30 children ranging from 2;6 to 7;11 in age, with none considered to have language or speech impairments. Language sample utterances were manually coded for the presence of adverbial clauses (both finite and non-finite). Samples were then automatically tagged using the computer software. Results were tabulated and compared for accuracy. ANOVA revealed differences in frequencies of so-adverbial clauses whereas ANACOVA revealed differences in frequencies of both types of finite adverbial clauses. None of the structures were significantly correlated with age; however, frequencies of both types of finite adverbial clauses were correlated with mean length of utterance. Kappa levels revealed that agreement between manual and automated coding was high on both types of finite adverbial clauses.

The purpose of this study was to examine the effects of using Systematic and Engaging Early Literacy (SEEL) intervention activities that incorporate digital books to teach kindergarteners to read. The study used a single-subject-multiple-baseline-across-behaviors design to compare kindergarten students' reading of comparable CVC words before and after intervention. Four students at-risk for reading difficulties were chosen for the study based on their performance on assessments and their teachers' recommendations. Students were divided into two dyads and received intervention three times a week for 25 minutes for approximately six weeks, or 18 total sessions. Baseline assessment data was collected prior to intervention, and performance on each target was monitored through the same assessment task after every intervention session. Students received SEEL instruction on one set of word targets while a comparable set was kept at baseline phase. After six intervention sessions on the first set of word targets, a second set was introduced while the first set was monitored for maintenance. Finally, a third set of target words was introduced and taught in six sessions, and the first two sets of words were monitored for maintenance. Instruction involved using meaningful and interactive activities that incorporated playful practice, multiple exposures to targets, explicit statement of the goal, and reciprocal teacher-student exchanges where students' contributions were acknowledged and incorporated into the lesson or meaning construction. After being exposed to the target words (orally and in writing), children were provided with additional opportunities to read and write the words within digital books created on the iPad.

Noun clauses are grammatical constructions that are of relevance both to typical language development and impaired language development. These clauses have been part of published techniques for the clinical analysis of language samples, and computer software for the automated analysis of clinical language samples has attempted to identify noun clauses, with limited success. The present study examined the development and clinical use of noun clauses as well as the automated identification of these clauses. Two sets of language samples were examined. One set consisted of 10 children with specific language impairment (SLI) whose age ranged from 7;6 to 11;1 (years;months), 10 peers matched for language development equivalence, and 10 peers matched for chronological age. The second set of samples were from 30 children considered to be typically developing, who ranged in age from 2;6 to 7;11. Language sample utterances were manually coded for the presence of noun clauses (including wh- noun clauses, that- noun clauses, and gerunds.) Samples were then automatically tagged using software. Results were tabulated and compared for accuracy. ANCOVA revealed that differences in the frequencies of WH-infinitive noun clauses and gerunds were significant between the matched groups. "Zero that clauses" (that-noun clauses containing no subordinator that) and gerunds were significantly correlated with age. Kappa levels revealed that agreement between manual and automated coding was high on WH-infinitive clauses, gerunds, and finite wh-noun clauses.

Event related potentials (ERPs) may provide specific information about how particular aspects of language are processed by the brain over time. This study investigated the electrophysiology of language processing in two children with language impairment (LI) when compared to five typically developing children. The N400, P600, and the early left anterior negativity (ELAN) were analyzed after participants listened to linguistically correct, syntactically incorrect, and semantically incorrect sentences. Participants were instructed to indicate whether the sentences were correct or incorrect. Latency and amplitude of the ERP components were compared between the two groups of participants and sentence types. Results from the current study concerning the typically developing children suggest that, at least by eight years of age, typically developing children may process linguistic information similarly to adults with regard to the areas of the brain that are activated during the processing of linguistic stimuli. When comparing results from participants with LI and their typically developing counterparts, results indicate that children with LI exhibit slower real-time language processing than typically developing children. Results also indicate that children with LI require more effort than typically developing children in processing linguistic information as indicated by the amplitude of the N400 and the ELAN. In analyzing the P600 in both groups of participants, results indicate that syntactic processing may be intact in children with LI as well as typical children. Results concerning the N400 and the ELAN were variable between the two participants with LI indicating that children with LI may be heterogeneous even in the presence of similar tasks. Results obtained from the ELAN may also indicate that the ELAN is not fully mature at eight years of age.

The purpose of this study was to investigate the effects of emotion on several key acoustic features of vibrato including vibrato rate, extent, and steadiness (measured by FM rate COV and FM extent COV). We hypothesized that intensity of emotion would have a significant effect on vibrato rate, extent, and periodicity, although the direction of these changes was undetermined. There were 10 participants, including eight females and two males, who were graduate student singers with high competency ratings. Each participant completed a series of tasks including sustained vowels at several pitch and loudness levels, an assigned song that was determined to have neutral emotion, and a personal selection that was selected because it included sections of intense emotion. Vowel tokens were averaged for each task, and measurements of mean f0, mean dB, FM rate, FM extent, FM rate COV and FM extent COV were calculated by task for each participant. Contrast analyses were performed comparing each task against the personal selection (high emotion) task. The results suggest that FM rate and FM rate COV may have been influenced by level of emotion, and FM extent, FM rate COV and FM extent COV were likely influenced by the performance nature of the task.

The purpose of this study was to examine the nature of conversational interactions between parents and their children during early literacy instructional activities. Parents engaged their children in interactions within hands-on activities designed to teach specific literacy skills as part of a kindergarten project entitled Systematic and Engaging Early Literacy (SEEL). Data for this study were extracted from audio and video recordings of parent-child interactions during three targeted literacy activities. Specialized software (LENA Pro) was used to analyze the interactions regarding adult and child use of targeted words (word count) and turn taking. To gain additional information about the exchanges, one exchange from each dyad was transcribed and analyzed using discourse analysis procedures. Findings from this study will be used to determine if children can be exposed to frequent and salient examples of targeted word patterns while engaging in playful and reciprocal interactive exchanges with their parents.

Hydration of the vocal folds is important for the production of normal voice. Dehydration makes voice production more difficult and increases vocal effort. Laryngeal desiccation has been shown to increase phonation threshold pressure (PTP) and self-perceived phonatory effort (PPE) in females. Nebulized saline may reverse or offset this effect. However, few data exist regarding the effects of laryngeal desiccation and nebulized treatments in males. Further, the dose-response relationship between laryngeal desiccation and nebulized hydration treatments is unknown. This study examined the effects of two doses of nebulized isotonic saline following a laryngeal desiccation challenge in healthy male speakers. In a double-blinded, within-subjects design, 10 male college students (age range 18-26 years) attended two data collection sessions involving a 30-minute desiccation challenge followed by 3 mL or 9 mL of nebulized isotonic saline. PTP for the 10th and 80th fundamental frequency (F0) percentiles and PPE were collected before and after the desiccation challenge and at 5, 35, and 65 minutes after the nebulized treatment. PPE increased significantly following the laryngeal desiccation challenge (p < .01). Following nebulization, PPE decreased toward baseline for both doses of isotonic saline (p < .01), but failed to reverse the desiccation effect completely. No statistically significant changes in PTP occurred following the laryngeal desiccation challenge or subsequent treatments. Compared with previous research involving females, these results suggest males may respond differently to laryngeal desiccation and nebulized hydration treatments.

Vocal fold hydration is important for healthy function of the vocal mechanism. Vocal fold surface fluid protects the mucosa and facilitates efficient vocal fold oscillation. Dry air exposure, mouth breathing, insufficient intake of liquids, and behavioral factors may contribute to laryngeal dehydration. Singers are believed to be particularly at risk for voice problems related to dehydration due to environmental and voice use factors. Laryngeal desiccation and nebulized hydration treatments have been shown to influence phonation threshold pressure (PTP) and self-perceived phonatory effort (PPE) in females. However, little research exists exploring the effects of hydration in males. Additionally, few studies have examined the dose-response relationship of hydration treatments. This investigation examined the effects of a laryngeal desiccation challenge and two different doses of nebulized isotonic saline on voice production in trained male singers. In a double-blind, within-subjects repeated measures crossover investigation, 10 male singers (ages 18 to 24) received a 30 minute laryngeal desiccation challenge followed by either 3 mL or 9 mL of nebulized isotonic saline on two consecutive weeks. PTP, PPE, and self-perceived mouth and throat dryness were sampled during the following observations: predesiccation, post-desiccation, and at 5, 35, and 65 minutes post-nebulization. No differences in PTP were observed after desiccation or nebulized treatment. PPE, however, rose significantly after desiccation and returned near baseline after treatment. No significant differences between dosages were observed.

Recent research indicates that many children with Language Impairment (LI) have difficulty with social communication skills. This study assessed the impact of a social communication intervention on teacher perceptions of social withdrawal in children who received the treatment. The intervention targeted emotion understanding using the presentation of children's stories, facial picture cards, and journaling. Teacher perception was measured using the three withdrawal subscales of the Teacher Behavior Rating Scale (TBRS): Solitary-Active withdrawal, Solitary-Passive withdrawal, and Reticence. Following treatment all five participants received lower ratings of withdrawn behavior on some of the subscales. Only one participant received a rating indicting increased withdrawn behavior (on a single subscale). The most positive indicators of change following treatment were the reduction in Solitary-Active withdrawal for three of the participants and the reduction of Reticent withdrawal for three participants. This study reveals promising results for social communication intervention in children with LI in the area of withdrawn behaviors.

This thesis project focused on the complexity of story generations produced by four children with language impairment across treatment sessions. Specifically, the participants' utterances were analyzed to determine if the children produced simple story elements and/or more complex cause/effect story elements. The children's utterances were also analyzed to identify emotion words in order to consider the children's awareness of the emotions experienced by characters in the stories. All participants approached the story generation task by describing characters and actions based on pictures from the book. Two participants did not express any causal relationships and two participants expressed some awareness of causal relationships, suggesting an emergence of this ability. Furthermore, participants' ability to recognize emotions varied. All of the children were able to label at least one emotion across sessions, and two participants increased production of emotion words across sessions. None of the participants linked character actions/reactions to the overall theme of the story. Further research is needed to determine effective ways to help children bridge the gaps between simple descriptions and more complex causal relationships.
