Abstract
The Bangor Gambling Task (BGT, Bowman & Turnbull, 2004) is a
simple test of emotion-based decision-making, with contingencies varying
across five blocks of 20 trials. This is the first study to
characterise BGT performance in survivors of traumatic brain injury
(TBI) relative to healthy controls. The study also aimed to explore
sub-groups (cluster analysis), and identify predictors of task
performance (multiple regression). Thirty survivors of TBI and 39
controls completed the BGT and measures of processing speed, premorbid
IQ, working memory, and executive function. Results showed that
survivors of TBI made more gamble choices than controls (total BGT
score), although the groups did not significantly differ when using a
cut-off score for ‘impaired’ performance. Unexpectedly, the groups did
not significantly differ in their performance across the blocks,
however, the cluster analysis revealed three subgroups (with survivors
of TBI and controls represented in each cluster). Findings also
indicated that only age and group were significant predictors of overall
BGT performance. In conclusion, the study findings are consistent with
an individual differences account of emotion-based decision-making, and a
number of issues need to be addressed prior to recommending the
clinical use of the BGT.
