Simple and Choice Reaction Time in Patients with Moderate and Severe Traumatic Brain Injury: A Longitudinal Examination of Change During the First Year of Injury
Year: 2020
Type: dissertation
Abstract: Moderate-to-severe traumatic brain injury (m-s TBI) can result in reduced speed of information processing and elevated reaction time intra-individual variability (RT-IIV). However, our understanding of longitudinal change during the first year of injury on measures of these processes is limited. This thesis employed a secondary analysis of findings from a simple- and a choice-reaction time (SRT; CRT) task to investigate change from 2- to 5- to 12-months following m-s TBI in (1) mean RT, (2) RT-IIV, and (3) ex-Gaussian parameters. We observed three different patterns of change depending on the outcome measure and/or analytic approach: asymptotic, characterized by significant early change (i.e., 2- to 5-months) and an absence of delayed change (i.e., from 5- to 12-months); ongoing, characterized by significant change from 2- to 5- to 12-months; and delayed, characterized by an absence of significant early change, but significant delayed change from 5- to 12-months. Clinical implications are discussed.
