Change Detection Of Emotional Information Across The Adult Lifespan, Maria J. Donaldson-Misener
Change Detection Of Emotional Information Across The Adult Lifespan, Maria J. Donaldson-Misener

Visual change detection ability is necessary for successful interaction with the environment, yet few studies have been conducted on change detection with older adults, and whether their use of top-down and bottom-up processing differs from younger adults, especially with emotional processing. Emotions can be motivating and guide the scope of attention using top-down processing and can capture attention in an automatic, bottom-up fashion. Theories of socioemotional aging suggest that younger and older adults may be differentially motivated to process positive and/or negative aspects of the environment, and these tendencies may have implications for age-related trajectories in well-being. Change detection efficacy …

Bilingualism Across The Adult Life-Span: Age And Language Usage Are Continuous Variables, Sara Incera Burkert

The purpose of this dissertation research was to analyze the effects of bilingualism and age on cognitive function. Specifically, I investigated the impact of bilingualism and age on two measures of executive control. The Stroop task is a measure of response inhibition, and the Flanker task is a measure of attention selection. Participants responded using a computer mouse. The mouse-tracking paradigm allowed me to examine the continuous dynamics of the responses as participants completed each trial. A better understanding of the impact of bilingualism and age on cognitive function has the potential to minimize cognitive decline in older age. The …

Acoustic And Respiratory Measures As A Function Of Age In The Male Voice, Mark Selent
ETD Archive
The purpose of this study was to extend understanding of the effects of aging on the male voice by obtaining and analyzing both acoustic and respiratory measures across the aging continuum. Aerodynamic measurements such as vital capacity (VC), maximum phonation time (MPT) and the acoustic measurement Speaking Fundamental Frequency (SFF) are used commonly in Speech-language Pathology to aid in the assessment and treatment outcomes of vocal dysfunction. However, current research lacks analysis of the interaction across these parameters within males and younger ages. This information may be important in understanding the normal changes in the speech mechanism with age and …
