This thesis examines a social communication intervention that targets the emotional competence of children with language impairment (LI). Three elementary school-aged children with LI received twenty, 20-minute intervention sessions over four months. Each intervention session involved a combination of activities targeting emotion recognition and emotion inferencing. The emotion-based word productions were counted and analyzed. Categorized words belonged to the emotional categories of happiness, sadness, anger, fear, surprise, and disgust. The percentage of appropriate usage was calculated to represent how often the participants used each emotion-based word in a semantically correct manner. Emotion word productions that did not match the intended target word were analyzed for valence agreement. Results were variable but two of the participants improved in the percentage of accurate productions in at least one emotional category while one participant did not improve over the intervention. Two of the participants also showed a decrease in the number of valence errors with no notable change in valence errors for the third participant. This suggests that this type of intervention can be effective in improving the use of emotion-based words in children with LI. More research is needed to develop this type of intervention.

Though the current understanding of language processing is incomplete, it has been established that the left hemisphere is dominant for language in the majority of the population. Damage to language centers of the brain and to white matter tracts connecting these language centers results in a language deficit known as aphasia. Neuroplasticity in the brain can often compensate for these language deficits by strengthening neuronal connections between the right and left hemisphere, or by enhancing the neuronal connectivity of undamaged areas in the left hemisphere. Thus the brain can compensate for damaged language centers by using alternative cortical areas. These compensatory language areas may be homologous areas of the right hemisphere, or other undamaged portions of the left hemisphere. Various imaging techniques have been used to demonstrate this phenomenon. The current neuroimaging technique known as quantitative electroencephalographic brain imaging allows investigators to evaluate the functional anatomical location of language processing. When this mapping is overlaid on a magnetic resonance image, investigators are able to locate areas in the brain of the participant that are electrically activated during elicited speech tasks. This method was used in a single case study to examine the brain of an individual with a unique traumatic brain injury in which the anterior portion of the individual's left temporal lobe was surgically removed and considerable recovery of language subsequently occurred. The stimulus for the quantitative electroencephalography included identifying syntactically incorrect sentences. Imaging results from the participant with traumatic brain injury were compared to imaging results obtained from an age-matched control. Differences in quantitative electroencephalography between the two participants included a delayed P1-N1-P2 response and an absent P600 in the participant with traumatic brain injury. Behavioral results include an increased number of incorrect responses from the participant with traumatic brain injury as compared to the control participant. These results imply an interesting cortical distribution of language processing that could be further assessed by functional magnetic resonance imaging.

Cross modality matching is a magnitude matching procedure, developed to study the relationships between sensory modalities. Auditory and visual sensory integration can be examined through cross modality matching of brightness and loudness. Brightness and loudness are natural correlates of one another as they both represent the parameter of intensity for their respective sensory modalities. Past studies have demonstrated that typical individuals tend to match brighter lights with louder sounds and dimmer lights with softer sounds. The current study utilized a modified cross modality matching procedure, combined with electroencephalography (EEG) data, to examine the cortical response to sensory integration. It was hypothesized that the response latency and cortical distribution of the EEG data would show differences between matched and unmatched conditions of light and sound stimuli. Light and sound stimuli were presented to 10 participants (five males and five females between the ages of 18 and 28 years) in a forced choice paradigm. The behavioral responses, reaction times, and EEG data were recorded for each patient. Results demonstrated that there were significant differences in behavioral reaction time among the stimulus conditions. However, reaction times were only significantly faster for the loudest sound paired with the brightest light. No other pairs of matched stimuli resulted in faster reaction times. Event related potentials (ERPs) were identified for matched and unmatched stimulus conditions. No differences were identified in latency of the ERPs among conditions. Additionally, source localization revealed that dipole locations for each stimulus condition remained relatively constant in the prefrontal cortex. As the prefrontal cortex has been found to be associated with decision-making and sensory integration, it can be concluded that sensory integration did occur. However, the processing of sensory information did not change for matched or unmatched conditions of light and sound.

Aphasia is a language disorder resulting from damage to brain areas that control language expression and reception. Clinically, the narrative production of Persons with Aphasia (PWA) provides valuable information for diagnosis of aphasia. There are several types of assessment procedures for analysis of aphasic's narrative production. One of them is to use quantification systems, such as the Cantonese Linguistic Communication Measure (CLCM; Kong & Law, 2004) or the Main Concept Analysis (MCA; Kong, 2009), for objective quantification of aphasic's discourse. The purposes of this study are (1) to translate the MCA and CLCM to a Taiwanese Mandarin Main Concept Analysis (TM-MCA) and a Taiwanese Mandarin Linguistic Communication Measure (TM-LCM), respectively, and (2) to validate them based on normal speakers and PWA in Taiwan. In the pilot study, a total of sixteen participants, eight certified speech-language pathologists (SLPs) and eight normal speakers, were invited to establish the Taiwanese Mandarin main concepts related to the four sets of sequencial pictures created by Kong in 2009. The language samples from eight normal speakers were then used to determine the informative words (i-words) in the picture sets. In the main study, thirty-six normal speakers and ten PWA were recruited to perform the same picture description tasks. The elicited language samples were analyzed using both the TM-MCA and TM-LCM. The results suggested that both age and education affected the oral discourse performance. Significant differences on the measures in TM-MCA and indices in TM-LCM were noted between the normal and aphasic groups. It was also found that overall aphasia severity affected the picture description performances of PWA. Finally, significant correlations between some of the TM-MCA measures and TM-LCM indices were noted. In conclusion, both the TM-MCA and TM-LCM are culturally appropriate to the Taiwanese Mandarin population. They can be used to supplement standardized aphasia tests to help clinicians make more informative decisions not only on diagnosis but also on a treatment plan of aphasia.

Recognition of the need for special education for school children with speech handicaps was first made in Potsdam, Germany, in 1896. Twelve years later in 1908 the first public school class in speech correction in the United States was organized in New York City, Programs of speech and hearing re-education in the public schools of the United States have expanded from this single metropolitan system in 1908 to a nation-wide effort in little more than fifty years. In the United States today more than two million school children require remedial services from competently trained speech clinicians. In California public schools alone more than 100,000 children each year receive special instruction in remedial classes conducted by more than five hundred full-time and part-time speech clinicians. Public school speech therapy has become a recognized discipline in American education, but continuing re-evaluations must be made to assure adequate future growth. This study does not purport to go into the etiology or methodology of speech and hearing problems, but rather to serve mainly as a source of information regarding the organization, administration, and financing of the special services which deal with these problems, In the preliminary stages of gathering the data for this research project, it was found that school districts seeking the services of a speech clinician for the first time were faced with the task of administering a program which is not clearly defined beyond the legal obligations as set forth by the Educational Code. Just what to expect from the new addition to their teaching staff presented a problem to the school district administrator. The speech clinician also was very seldom prepared to offer a well-defined workable outline as to his responsibilities to the school district which had employed him. To determine the role of the speech clinician in this area and how the programs of speech therapy are organized, administered, and financed, seventeen school districts within a one hundred mile radius of Lodi, California, were randomly selected for this study.

The purpose of this study was to contribute to the understanding of the effects of aphasia couples therapy (ACT) in a person with conduction aphasia. ACT is a social therapeutic approach that involves facilitating conversations between the person with aphasia (PWA) and their spouse, or caregiver. The participants in this study involved one pair. The dependent variables included conveyance of main concepts, use of intentional gestures, reflections and summary statements per conversation. Miscellaneous measures were also counted and analyzed including the PWA’s frequency of paraphasias, fillers (e.g. um, uh), and disfluencies. Baseline sessions involved the PWA watching a video clip, and then providing a verbal summary of the main concept of the clip to his non-aphasic spouse within a 10-minute conversation. Therapy treatment sessions followed the same format as the baseline sessions, however, therapy sessions also included the aide of the researcher to coach the participants to use their pre-selected communication strategies to improve the balance in their conversations. The ability to accurately convey the main concept of a video clip in conversation served as the primary dependent variable in this study. Follow-up sessions were also conducted in similar fashion to baseline and probe sessions to determine maintenance and validity of results by dividing the total number of main concepts by the total number of utterances per conversation. Furthermore, ratings of the PWA’s quality of life and confidence in his ability to communicate were gathered and compared. The results of this study indicated that ACT yielded improved effects for the couple with regards to the communication of main concepts per conversation. A decrease in the use of all included miscellaneous measures were also observed. However, no significant changes were noted with regards to use of intentional gestures, reflections, and summary statements.

Developmental Sentence Scoring (DSS) is a standardized language sample analysis procedure that uses complete sentences to evaluate and score a child’s use of standard American-English grammatical rules. Automated DSS software can potentially increase efficiency and decrease the time needed for DSS analysis. This study examines the accuracy of one automated DSS software program, DSSA Version 2.0, compared to manual DSS scoring on previously collected language samples from 30 children between the ages of 2;5 and 7;11 (years;months). The overall accuracy of DSSA 2.0 was 86%. Additionally, the present study sought to determine the relationship between DSS, DSSA Version 2.0, the mean length of utterance (MLU), and age. MLU is a measure of linguistic ability in children, and is a widely used indicator of language impairment. This study found that MLU and DSS are both strongly correlated with age and these correlations are statistically significant, r = .605, p < .001 and r = .723, p < .001, respectively. In addition, MLU and DSSA were also strongly correlated with age and these correlations were statistically significant, r = .605, p < .001 and r = .669, p < .001, respectively. The correlation between MLU and DSS was high and statistically significant r = .873, p < .001, indicating that the correlation between MLU and DSS is not simply an artifact of both measures being correlated with age. Furthermore, the correlation between MLU and DSSA was high, r = .794, suggesting that the correlation between MLU and DSSA is not simply an artifact of both variables being correlated with age. Lastly, the relationship between DSS and age while controlling for MLU was moderate, but still statistically significant r = .501, p = .006. Therefore, DSS appears to add information beyond MLU.

The purpose of this study was to analyze the phonetic production of fricatives across differing word positions and task types. Further knowledge about the fricative production of second language learners of English would potentially improve the ability to teach correct pronunciation and improve the productivity of second language programs. All participants in this study were native speakers of Mandarin Chinese with English as their second language. A total of 12 subjects participated, all of whom had English proficiency ratings ranging from novice to advanced. The speakers were between 21-51 years of age, with each speaker having between 2 to 6 years of experience learning English in their country of origin. Using acoustic and spectral moment analyses, the acoustic nature of four types of fricative productions (/f/, /θ/, /s/, and /ʃ/) were analyzed as a function of linguistic task type and word position. Although a number of measures were found to differ significantly as a function of word position and task type, the majority of statistical analyses were not found to be significant. This lack of significance may be due to the specific methodology used, the speakers atypical voicing patterns, and/or decreased length of sound productions. Findings of this study may indicate that second language learners production of fricatives vary minimally across differing word positions and task types.

Historically, social communication approaches to intervention for children with developmental language disorders (DLD) have been limited. However, several recent studies have shown that these interventions can produce positive changes in children with DLD. One weakness that children with DLD demonstrate is the production of words to express emotion. This thesis evaluates the effectiveness of a story-based social communication intervention to increase the production of emotion words in three elementary school-age children diagnosed with DLD. Data were collected and analyzed in pre-treatment baseline sessions, throughout the intervention, and in post-treatment follow-up data for the seven target emotion word categories of happiness, surprise, fear, anger, sadness, disgust, and contempt. The specific targeted emotion word categories were determined based on individual participants limited proficiency during baseline sessions. Thus, the emotions targeted were unique to each child. Intervention consisted of 40 intervention sessions using a combination of storybook therapeutic strategies (e.g., story enactment, story sharing, and modeling by the clinician to help increase the child's emotion understanding) as well as emotion recognition and emotion inferencing tasks. Each participants data were analyzed and presented in figures. The percentage of non-overlapping data (PND) was used in data analysis, quantifying how successful the intervention was for each of the targeted emotions. While the target emotion word categories varied between participants, all of the children showed improvement in the targeted emotions. While the intervention was more effective for some children than others, all increased in their ability to use the target emotion words more accurately as a result of participating in intervention.

Children with Developmental Language Disorder (DLD) often have difficulties with social and emotional learning, including emotion understanding and inferencing. Five children with DLD, ages 6;4 to 11;9, identified emotions depicted in pictured scenarios over a period of 10 weeks. Emotion categories included happy, sad, anger, fear, surprise, and disgust. Each child's responses were analyzed and plotted on a confusion matrix. In a few cases, children did not interpret the scenario accurately. Even when they interpreted the scenario accurately, all of the children misapplied, overgeneralized, or confused emotion labels in some cases. These errors represented limitations in social and emotional learning that could negatively impact the ability to interact with others, to establish and maintain relationships, and to succeed academically.
