AbstractProspective memory (PM) is the ability to remember to perform a future action at a specified later time, which is investigated through the use of event-based and time-based tasks. Prior investigations have found that PM is impaired following traumatic brain injury (TBI). However, there is limited information regarding the cognitive functions that mediate TBI and PM performance. Thus, this study investigated time-based PM in TBI patients, and the relationship among time-based PM, time perception, and executive functions. To accomplish this objective, 18 severe TBI patients and 18 healthy matched controls performed a time-based PM task, a time reproduction task, and two executive functions (Stroop and n-back) tasks. While both groups increased their monitoring frequency close to the target time, TBI patients monitored more and were less accurate than healthy controls at the target time confirming the time-based PM dysfunction in these patients. Importantly, executive functions, particularly inhibition and updating abilities, were strongly related to time-based PM performance; both time perception and executive functions are involved in time-based prospective memory in controls, whereas, only executive functions appear to be involved in TBI time-based prospective memory performance.

Abstract Objective We investigated whether clock-checking frequency during a prospective memory (PM) task differed between Veterans with reported histories of blast-related mild traumatic brain injury (mTBI) and Veteran Controls (VCs) without a history mTBI. We hypothesized that, compared to controls, the mTBI group would less frequently clock check. Additionally, we expected that reduced clock-checking would contribute to poorer time-based PM performance in the mTBI group. Method Twenty-seven Veterans (9 mTBI and 18 VC) with sufficient effort testing completed a structured TBI history interview, the Post-Traumatic Stress Disorder Checklist (PCL) and the Memory for Intentions Test (MIST) as a PM task. During MIST administration, examiners recorded clock-checking behavior each time a participant physically turned a digital clock to observe the current time. Results Compared to VCs, the mTBI group performed worse on the Time subscale of the MIST [Mean (SD) VC = 6.7 (1.1), mTBI = 5.7 (1.1), p < .05], and demonstrated significantly fewer clock-checks over the duration of the test [VC = 14.2(4.7), mTBI = 10.2 (3.4), p < .05]. Clock-checking significantly correlated with MIST Time subscale performance (r = .38, p < .05). Groups did not significantly differ in PCL scores, and PCL scores did not significantly correlate with clock-checking counts. Conclusion Our preliminary results are the first to show that clock-checking behavior may contribute to reduced performance on time-based PM tasks in Veterans with histories of mTBI. Specifically, our findings demonstrate that participants with mTBI employ an inefficient time monitoring strategy wherein infrequent clock checking contributes to poorer test performance. These findings suggest that strategies to improve clock checking may improve PM performance.

AbstractThe current study aimed to investigate prospective memory in traumatic brain injury by using a laboratory-based but naturalistic style assessment task. The objective was to determine if performance differed when the prospective memory targets were self-generated or experimenter-generated (a generation effect). Sixteen people who had sustained a traumatic brain injury and had received rehabilitation were compared to 16 healthy age-matched control participants on a naturalistic virtual measure of shopping and prospective memory. Results demonstrated that the traumatic brain group was less accurate in overall prospective remembering performance than the control group but there was a lack of difference between the self- and experimenter-generated prospective memory targets for both participant groups. Both retrospective memory and executive attention of working memory were associated with prospective memory performance in the naturalistic task. The findings of the study suggest that the generation effect commonly observed in retrospective memory performance may not impact performance in prospective memory.

AbstractThere are very few studies investigating remediation of event-based prospective memory (EB-PM) impairments following traumatic brain injury (TBI). To address this, we used 2 levels of motivational enhancement (dollarsvs.pennies) to improve EB-PM in children with moderate to severe TBI in the subacute recovery phase. Children with orthopedic injuries (OI;n= 61), moderate (n= 28), or severe (n= 30) TBI were compared. Significant effects included Group × Motivation Condition (F(2, 115) = 3.73,p< .03). The OI (p< .002) and moderate TBI (p< .03) groups performed significantly better under the high-versuslow-incentive condition; however, the severe TBI group failed to demonstrate improvement (p= .38). EB-PM performance was better in adolescents compared to younger children (p< .02). These results suggest that EB-PM can be significantly improved in the subacute phase with this level ofmonetaryincentives in children with moderate, but not severe, TBI. Other strategies to improve EB-PM in these children at a similar point in recovery remain to be identified and evaluated. (JINS, 2010,16, 335–341.)

Prospective Memory Performance

AbstractTraumatic brain injury (TBI) patients often present with prospective memory (PM) dysfunction. Forgetting to complete tasks may result in a loss of independence, limited employment prospects and anxiety, therefore, it is important to develop programs to improve PM performance in TBI patients. A strategy which may improve PM performance is implementation intentions. It involves making explicit plans specifying when, where and how one will perform a task in the future. In the present study, a group of 36 TBI patients and a group of 34 controls performed Virtual Week using either implementation intentions or no strategy. The results showed that the PM performance of TBI patients was less accurate than controls, in particular when the PM cue was time-based. No effect of implementation intentions was observed for TBI patients, however, controls improved their PM performance when the task was time-based. The findings suggest that strategies to improve PM in this clinical group are likely to be more complex than those that benefit healthy adults and may involve targeting phases of the PM process other than, or in addition to, the intention formation phase.
