Information regarding the remediation of event-based prospective memory (EB-PM) impairments following pediatric traumatic brain injury (TBI) is scarce. Addressing this, two levels of monetary incentives were used to improve EB-PM in children ages 7 to 16 years with orthopedic injuries (OI, n = 51), or moderate (n = 25) and severe (n = 39) TBI at approximately 3 months postinjury. The EB-PM task consisted of the child giving a specific verbal response to a verbal cue from the examiner while performing a battery of neuropsychological measures (ongoing task). Significant effects were found for age-at-test, motivation condition, period, and group. Within-group analyses indicated that OI and moderate TBI groups performed significantly better under the high- than under the low-incentive condition, but the severe TBI group demonstrated no significant improvement. These results indicate that EB-PM can be significantly improved at 3 months postinjury in children with moderate, but not severe, TBI.

    ABSTRACT: Few studies exist investigating the brain-behavior relations of event-based prospective memory (EB-PM) impairments following traumatic brain injury (TBI). To address this, children with moderate-to-severe TBI performed an EB-PM test with two motivational enhancement conditions and underwent concurrent diffusion tensor imaging (DTI) at 3 months post-injury. Children with orthopedic injuries (OI; n=37) or moderate-to-severe TBI (n=40) were contrasted. Significant group differences were found for fractional anisotropy (FA) and apparent diffusion coefficient for orbitofrontal white matter (WM), cingulum bundles, and uncinate fasciculi. The FA of these WM structures in children with TBI significantly correlated with EB-PM performance in the high, but not the low motivation condition. Regression analyses within the TBI group indicated that the FA of the left cingulum bundle (p=0.003), left orbitofrontal WM (p<0.02), and left (p<0.02) and right (p<0.008) uncinate fasciculi significantly predicted EB-PM performance in the high motivation condition. We infer that the cingulum bundles, orbitofrontal WM, and uncinate fasciculi are important WM structures mediating motivation-based EB-PM responses following moderate-to-severe TBI in children.

    ABSTRACT: Prospective memory is the ability to remember to execute future intentions and thoughts. It is probably the newest established field of memory research. We provide a selective review of work conducted in the last two decades with respect to the following issues: (1) the different types and characteristics of prospective tasks, (2) the theoretical models of the cognitive processes support-ing prospective memory, (3) prospective memory performance in younger and older adults and (4) the findings from neuropsychological and neuroimaging studies. The findings indicate an extraordinarily fast progress in our under-standing of the behaviour and the brain regions that are involved in this impor-tant ability, and suggest at least two possible emerging areas of enquiry for future research: a link with the closely related field of prospection (i.e., think-ing about the future), and "expectation prospective memory" (triggering of behaviour in the absence of awareness depending on contingencies learnt from the environment). Prospective memory (PM) is commonly defined as the set of abilities that are used when remembering to perform an intended action, or thought, at some future point (Brandimonte, Einstein, & McDaniel, 1996). This type of mem-ory is in constant use in everyday life in order to fulfil intentions ranging from the simple, such as remembering to take out the garbage when leaving home, to the more complex, such as remembering to organise a surprise party for a friend's birthday. This ability is critical to competent human functioning, so much so that previous studies have suggested that PM problems are the most frequent memory failures in everyday life (Kliegel & Martin, 2003). Rela-tively little experimental and theoretical investigation was conducted on this topic until the last 15 years. However, since then there has been a remarkable increase in number of research studies that have considered PM.

    ABSTRACT: Prospective memory (PM) is the ability to carry out an intended action in the future. Failures in PM are often observed as more frequent in individuals with traumatic brain injury (TBI) than controls. However, it remains unknown how individuals with TBI and their significant others perceive the importance of these PM problems. In the current study, four groups (38 TBI, 34 TBI-other, 34 controls, 31 control-other) were recruited to report on the perceived importance of PM failures using Part B of the Comprehensive Assessments of Prospective Memory (CAPM). Individuals with TBI perceived PM failures as being more important than did their significant others. Controls' ratings did not differ from their significant others. There were no statistically significant differences in rated importance for PM problems involving the basic activities of daily living (BADL) component and those involving the instrumental activities of daily living (IADL) component. Implications of the results are discussed in terms of the motivation of people with TBI.
