Exploring Picture Word Priming Effects In Healthy Aging Adults Using Event Related Potentials, Sasha C. Christopher

USF Tampa Graduate Theses and Dissertations

Objective: The aim of the present study was to investigate the mechanics with which older adults activate and access different subdomains of their mental lexicons during word retrieval for picture naming.

Method: Data were analyzed for 12 aging, native English speakers who performed a picture-word priming task. The auditory probe words were presented in the following conditions in relation to the picture stimuli: Identically related, strongly semantically related, weakly semantically related, strongly phonologically related, weakly phonologically related, semantically related to the strong phonological relative of the target picture label, or phonologically-related to the strong semantic relative of the target picture …

Self-Modeling As An Intervention For Stuttering In Elementary Students, Jason Northrup

Legacy Theses & Dissertations (2009 - 2024)

Stuttering is a disorder involving disruptions and disfluencies in speech that impacts overall communication and affects approximately 1% of the population. In addition to speech disfluency, stuttering is often related to physical tension, embarrassment, fear, anxiety, and other negative social-emotional problems, especially for children and adolescents. Fortunately, research indicates that stuttering can be alleviated before becoming more advanced and complex as individuals enter adolescence and adulthood. Self-modeling, an intervention that involves individuals watching themselves engage in exemplary behavior, appears to be particularly effective for individuals who stutter and can be implemented in a school setting. The purpose of this study …

Age, Attention, And Ots In A Constrained Vs Unconstrained Task, Courtney Leann Jensen

Theses and Dissertations--Rehabilitation Sciences

The discourse of older healthy adults is commonly described as lengthy and off-topic and thought to be associated with a general cognitive decline that occurs in healthy aging. This study investigated the overall decline in attention associated with healthy aging and its relationship to instances of off-topic speech (OTS) in a constrained and unconstrained language production task. Ninety cognitively healthy adults participated and comprised three age cohorts (40 – 75+). Participants completed cognitive measures of attention and two discourse tasks that included recounting personal events and describing a procedure. Older adults exhibited poorer scores on measures of selective and shifting …

Semantic Feature Distinctiveness And Frequency, Katherine Marie Lamb

USF Tampa Graduate Theses and Dissertations

Lexical access is the process in which basic components of meaning in language, the lexical entries (words) are activated. This activation is based on the organization and representational structure of the lexical entries. Semantic features of words, which are the prominent semantic characteristics of a word concept, provide important information because they mediate semantic access to words. An experiment was conducted to examine the importance of semantic feature distinctiveness and feature frequency in accessing the lexical representations of young and older adults in an off-line task using features of animals. The McRae, Cree, Seidenberg, and McNorgan (2005) feature norm corpus …
