, 2007), additional cognitive tasks of attention, memory and executive function were also implemented. Nine individuals (2 women, 7 men; Mage = 38.4 years; SD = 17.3; Range 17–69 year) with TBI were selected from patients currently hospitalized at the regional hospital Hammel Neurocenter, a highly specialized rehabilitation centre for people with acquired brain damage, on the basis of medical evidence that they had sustained moderate-to-severe TBI. Six of the TBI participants suffered a severe TBI, defined by a post-resuscitation score of 8 or less on the Glasgow Coma Scale (GCS; Teasdale & Jennett, 1974). The remaining

three participants suffered a moderate TBI classified by GCS scores between 9 and 12 (n = 2) or by a GCS score higher than 12 accompanied by a positive neuroimaging finding and neurosurgery. All participants experienced an extended period of post-traumatic amnesia (PTA) see more (MPTA = 19.33; SD = 16.84; MK-1775 research buy Range 2–56 days), assessed by medical records and clinical questioning of the participants. TBI participants were assessed between 39 and 117 days after injury (M = 64.33; SD = 22.26). All patients were screened on intake, and participants with aphasia or whose gravity of comprehension, attention, and behavioural problems would invalidate the assessment were excluded. None of the participants suffered from any pre-injury,

psychiatric, or neurological disorders or had any history of prior substance abuse. Five TBI participants suffered their head injuries as a result of a motor vehicle 上海皓元医药股份有限公司 accident, three incurred injury from a fall and one TBI participant experienced a blow to the head. Computed tomography (CT) or Magnetic Resonance Imaging (MRI) showed a predominance of diffuse and frontal lobe lesions. The comparison group consisted of nine healthy participants (4 women, 5 men, Mage = 30.67 years; SD = 12.35; Range =  20–57 year), with no history of neurological or psychiatric disorder, or substance abuse recruited on a voluntary basis. There was no significant difference between groups in age (t(16)=1.10, p = .29)

and premorbid IQ, as estimated by the Danish adaptation of the National Adult Reading Test (DART; Dalsgaard, 1998; (t(10.73) = −1.10, p = .30). Although not significant, there was a greater age-range in the TBI group, due to one patient being much older (69 years old). Excluding this patient did not change the results, and we therefore chose to include all of the patients regardless of age. The control group included slightly more women (4 of 9) compared with the patients (2 of 9), but this difference was not significant (Fischer’s exact test, p = .62). The controls had on average spent more years in school than the TBI participants (t(8) = −6.11, p < .001), but when examining formal level of education [no education (incl.
