Augmentative And Alternative Communication Systems In The Classroom, Helen Angela Mezzomo

Walden Dissertations and Doctoral Studies

Augmentative-alternative communication (AAC) systems are used to give voice to individuals who are nonverbal. As AAC systems become more complex and prevalent in the classroom expectations of school-based professionals expand. However, the roles of those expected to support AAC systems, primarily teachers and speech-language pathologists (SLPs), are not clearly defined. Without clearly defined roles, professionals may not provide needed support to students who use AAC. Dewey's theory of community suggests that role confusion leads to insufficient and ineffective services. The purpose of this cross-sectional quantitative study was to determine how teachers and SLPs view their roles in supporting AAC. The …

The Picture Exchange Communication System: Digital Photographs Versus Picture Symbols, Carmen Jonaitis

Dissertations

The Picture Exchange Communication System (PECS) is an augmentative and alternative system (AAC) used to improve and increase communication for children with Autism Spectrum Disorder (ASD) and other developmental disorders. Research addressing the efficacy of this system is increasing; however, there is limited information published that evaluates the picture type used for PECS instruction. A single-subject alternating treatments design was used to examine the role of iconicity, or how closely a symbol resembles its referent, in the acquisition of picture discrimination in the third phase of PECS. The purpose of this study was to compare how well children were able …

Memory And Language: Evidence Of Relationships From Three Studies Of School-Age Children, Michele A. Anderson

Dissertations

The purpose of this three-paper dissertation was to explore the relationship between performance on verbal memory and language assessment tasks in school-age children. Study one used data from whole-class administration of three language assessment tasks to 2nd, 4th, 6th, and 9th graders (N= 187). Studies two and three used data from individualized administration of language assessment and verbal memory tasks to comparable samples of children between the ages of 6 and 18 years with typical language (TL) and language impairment (LI) (n = 37 per group).

The first study addressed practical and theoretical questions regarding memory and language demands of …

Evaluation Of Verbal Behavior In Older Adults, Amy Gross

Dissertations

Older adults make up a large and increasing portion of the population (U.S. apply those assessments to the evaluation of verbal behavior in older adults with and without dementia. The research addressed two questions. First, in what way do verbal behavior problems differ between older adults with and without dementia? Second, does language deteriorate in a pattern compatible with Skinner's analysis of functionally independent verbal operants? Thirty-one participants were categorized into Control (n=15) and Dementia (n=16) Groups based on their score on the Dementia Rating Scale-2. Verbal behavior assessments were administered to participants on two occasions, separated by one week. …

Beliefs, Concerns, And Methods Of Parents Raising Children Bilingually: A Study Of Hispanic Iowa Mothers Attempting To Maintain Heritage Language In Their Children, Briana Vera

Honors Program Theses

The purpose of my thesis was to discover more about parents who are raising their children to be English-Spanish bilingual, particularly their beliefs, concerns, and methods regarding this issue. I focused specifically on mothers in Iowa whose native language was Spanish and who had at least one child in the household between the ages of four and sixteen. A point of interest I focused on were the beliefs, concerns, and methods these mothers have and use to maintain their children‟s heritage language (Spanish) as the community language (English) becomes more prominent in their children‟s lives. This information is important for …

Perspective Shifting In Relative Clauses By Elementary-Aged Spanish-English Bilinguals: A Cross-Linguistic Study, Xigrid Tayri Soto

USF Tampa Graduate Theses and Dissertations

Language-specific theories of sentence processing suggest that individuals interpret sentences based on the characteristics of their native language (e.g., Bates & MacWhinney, 1989). As such, competing linguistic cues are taken into account (including word order, morphology, and animacy) and the cue selected is most likely to yield a correct interpretation in the native language. However, research in this area has produced conflicting results. MacWhinney (2005) has proposed that examining the role of perspective shifting in sentence comprehension may demonstrate how cognitive and syntactic factors work together to facilitate sentence comprehension. The aim of the current study is to investigate the …
