“…Current estimates suggest that the US prevalence of TBI-related disability after hospitalization is 3.2 million individuals [12] and that 43.3% of hospitalized TBI survivors will have long-term disability [13]. Behaviorally, TBI survivors report confusion, disorientation, alteration in psychomotor activity, mental inflexibility, emotional dysregulation, and increased agitation [14,15]. Numerous studies also suggest that TBI has negative psychiatric consequences.…”

Traumatic brain injury (TBI) is a significant public-health concern. To understand the extent of TBI, it is important to assess the prevalence of TBI in the general population. However, the prevalence of TBI in the general population can be difficult to measure because of differing definitions of TBI, differing TBI severity levels, and underreporting of sport-related TBI. Additionally, prevalence reports vary from study to study. In this present study, we used meta-analytic methods to estimate the prevalence of TBI in the adult general population. Across 15 studies, all originating from developed countries, which included 25,134 adults, 12% had a history of TBI. Men had more than twice the odds of having had a TBI than did women, suggesting that male gender is a risk factor for TBI. The adverse behavioral, cognitive and psychiatric effects associated with TBI coupled with the high prevalence of TBI identified in this study indicate that TBI is a considerable public and personal-health problem.

“…By this method, many studies have reported significant differences in Pe morphology across a range of clinical groups (e.g., Brazil et al, 2009; O'Connell et al, 2009a; Olvet et al, 2010; Larson et al, 2011; Luijten et al, 2011; Perez et al, in press; Peterburs et al, 2012) and genotypes (Frank et al, 2007; Althaus et al, 2010; Biehl et al, 2011), and via pharmacological manipulation (Bartholow et al, 2012). In many cases these differences have been reported in the absence of an explicit indication of error awareness, and the present results highlight an important limitation of characterizing the Pe in this way.…”

“…Hence, while it is clear that the Pe is exclusively elicited by consciously perceived errors, previous research has been largely unable to go beyond this “binary” characterization to examine the extent to which variation in Pe amplitude and latency relates to fluctuations in the timing of awareness. This presents a significant problem in interpreting the findings of clinical studies in which group differences in Pe morphology have been reported (e.g., Brazil et al, 2009; O'Connell et al, 2009a; Olvet et al, 2010; Larson et al, 2011; Luijten et al, 2011; Perez et al, in press; Peterburs et al, 2012). …”

Recent electrophysiological research has sought to elucidate the neural mechanisms necessary for the conscious awareness of action errors. Much of this work has focused on the error positivity (Pe), a neural signal that is specifically elicited by errors that have been consciously perceived. While awareness appears to be an essential prerequisite for eliciting the Pe, the precise functional role of this component has not been identified. Twenty-nine participants performed a novel variant of the Go/No-go Error Awareness Task (EAT) in which awareness of commission errors was indicated via a separate speeded manual response. Independent component analysis (ICA) was used to isolate the Pe from other stimulus- and response-evoked signals. Single-trial analysis revealed that Pe peak latency was highly correlated with the latency at which awareness was indicated. Furthermore, the Pe was more closely related to the timing of awareness than it was to the initial erroneous response. This finding was confirmed in a separate study which derived IC weights from a control condition in which no indication of awareness was required, thus ruling out motor confounds. A receiver-operating-characteristic (ROC) curve analysis showed that the Pe could reliably predict whether an error would be consciously perceived up to 400 ms before the average awareness response. Finally, Pe latency and amplitude were found to be significantly correlated with overall error awareness levels between subjects. Our data show for the first time that the temporal dynamics of the Pe trace the emergence of error awareness. These findings have important implications for interpreting the results of clinical EEG studies of error processing.

Think aloud and forced on task-verbalizations are problematic in that they inevitably become a dual task paradigm and/or a prospective memory task: They require additional attention allocation to the task of showing the examiner an error has been detected.…”

Self-awareness has multiple components that need to be assessed separately, to better adapt cognitive rehabilitation. Using questionnaires and discrepancy scores are not sufficient to assess awareness, because it does not include on-line error detection, which can be massively impaired in children, especially those with impaired executive functions. On-line error detection is important to promote and error-based learning is useful to allow a child to build a self-knowledge of his/her strengths and difficulties, in the absence of severe episodic memory problems. Metacognitive trainings may not be appropriate for younger children who have age appropriate developmentally immature self-awareness, nor for patients with brain injury if they suffer anosognosia because of their brain injury.
