Abstract

Brain injury is associated with a reduced capcity to engage in effective cognitive estimation. The current study utilized two measures of this construct, the Cognitive Estimation Test (CET) and Luria Memory Test (Luria), to investigate the relationships between cognitive estimation and intelligence, memory, and affect in a sample of 30 traumatically brain-injured individuals. Results demonstrated significant correlations between cognitive estimation and tests of intelligence and memory. However, measures of depression and state anxiety were not meaningfully associated with cognitive estimation. The ability to recall stories accounted for the greatest portion of the variance for both the CET and Luria. Specifically, the 30-minute Logical Memory subtest from the Wechsler Memory Scale-Revised accounted for 38% of the variance in the CET, while the Logical Memory 30-minute savings score accounted for 47% of the variance in the Luria. Intellectual and affective variables explained only negligible amounts of variance on cognitive estimation tasks.
