White Matter Integrity And Age Related Differences In Reaction Time Components, Yiqin Yang
White Matter Integrity And Age Related Differences In Reaction Time Components, Yiqin Yang
Wayne State University Dissertations
Reduced speed in information processing is a well-documented phenomenon associated with advanced aging. Age-related deterioration in white matter integrity might play a role in age-related increase in reaction time (RT). However, the association between microstructural differences in particular white matter regions or tracts with RT is unclear. Decomposing RT into parts might be a better way to understand the relationship due to multiple processes involved in RT. In a lifespan sample of 90 healthy normotensive participants, this study examined the association between RT components derived from the Ratcliff diffusion model with age related difference in DTI indices of a wide …
The Influence Of Gender And Aging On The Neural Circuitry Supporing Facial Emotion Processing In Adults With Major Depressive Disorder, Emily Briceno
The Influence Of Gender And Aging On The Neural Circuitry Supporing Facial Emotion Processing In Adults With Major Depressive Disorder, Emily Briceno
Wayne State University Dissertations
Major Depressive Disorder (MDD) is associated with decrements in facial emotion processing (FEP). Previous studies investigating the neural substrates of these decrements have often reported hyperactivity of emotion processing circuitry. Neural circuitry supporting FEP has been shown to be different between healthy men and women, and between young and elder adults. However, no prior studies have investigated how gender and aging affect emotion processing circuitry in individuals with MDD. The present study aimed to investigate the influence of gender and aging on emotion processing circuitry in MDD. One hundred-ten adults, grouped into subgroups according to MDD status, gender, and age …
Neuropsychological Outcome In Relation To Duration Of Early Orphanage Experience, Jacquelyn Marie Perry Avery
Neuropsychological Outcome In Relation To Duration Of Early Orphanage Experience, Jacquelyn Marie Perry Avery
Wayne State University Dissertations
In this sample of 144 children with a history of prior orphanage experience, increasing duration of institutionalization is related to decreasing performance for a number of cognitive domains, most consistently verbal measures and executive Functioning measures. The relationships with duration for measures requiring visual-spatial skills were more mixed and a visual reasoning task was found to significantly relate to duration but not a measure of visual memory or a measure of nonverbal achievement. There was little evidence to support a relationship between the duration of institutionalization and fine-motor dexterity. The strongest relationships with duration were observed for language measures followed …
