Abstract
Prospective memory (PM), which can be understood as the processes involved in realizing a delayed intention, has been found to be impaired following a traumatic brain injury (TBI). Although PM can be empirically dissociated from retrospective memory, it inherently involves both prospective and retrospective components. This study utilized a formal multinomial processing tree (MPT) model that was developed and validated by Smith and Bayen (2004) to disentangle the prospective and retrospective recognition components underlying PM following TBI. Fifteen participants with a moderate to severe TBI and 15 age- and educationmatched control participants completed an event-based PM task that was embedded within an ongoing computer-based color-matching task. Results of the MPT modeling revealed a trend towards group differences in the prospective component and significant group differences in the retrospective recognition component of PM, despite intact post-test recall of the PM task and target words. More traditional data analyses revealed a significant cost to ongoing task performance with the inclusion of the PM task. Overall, our data suggested that our event-based PM task was resource demanding, and TBI participants tended to have difficulty with both the prospective and retrospective recognition aspects of PM.
