That learning and memory deficits persist many years following mild traumatic brain injury (mTBI) is controversial due
to inconsistent objective evidence supporting subjective complaints. Our prior work demonstrated significant reductions
in performance on the initial trial of a verbal learning task and overall slower rate of learning in well-motivated mTBI
participants relative to demographically matched controls. In our previous work, we speculated that differences in strategy
use could explain the differences in rate of learning. The current study serves to test this hypothesis by examining strategy
use on the California Verbal Learning Test-Second Edition. Our present findings support the primary hypothesis that
mTBI participants under-utilize semantic clustering strategies during list-learning relative to control participants. Despite
achieving comparable total learning scores, we posit that the persisting learning and memory difficulties reported by some
mTBI patients may be related to reduced usage of efficient internally driven strategies that facilitate learning. Given that
strategy training has demonstrated improvements in learning and memory in educational and occupational settings, we
offer that these findings have translational value in offering an additional approach in remediation of learning and memory
complaints reported by some following mTBI.
