Objectives. We hypothesized that simulated malingerers would show a we
aker priming effect and a longer response latency than control patient
s and patients with a brain injury on a priming test. Design. Particip
ants were compared on their performance on the Colorado Priming Test t
o replicate and extend the original validation study. Methods. Of 33 p
articipants, 16 were people with a brain injury and 17 were non-head i
njured control patients who were also instructed to feign cognitive im
pairment (simulators N = 17). Results. Up to 88 per cent of simulating
malingerers and 75 per cent of head-injured participants were correct
ly classified. Conclusions. The Colorado Priming Test may be useful in
identifying patients feigning memory impairment.
