Abstract
This study used a semantic-category visual search task
to investigate skill acquisition and automatic process
development in a severe closed-head injured (CHI) population.
Eighteen severe CHI participants (> 1 year post injury)
and 18 matched controls completed over 3600 trials of training
in both consistent mapping (CM) and varied mapping (VM)
training situations. Transfer conditions were also used
to test for development of an automatic attention response
(AAR) that was independent of general, task-related learning.
For both the severe CHI and control group, CM training,
where individuals always responded in the same way to a
specific class of stimuli, resulted in dramatic performance
improvements and the development of an AAR. In the VM training
condition, where individuals could not respond in the same
way to a class of stimuli from one stimulus exposure to
the next, there was little performance improvement and
continued reliance on controlled processes. The visual
search rates of the CHI participants also remained slower
than those of controls following extended VM but not extended
CM practice. These results indicate that skill acquisition
training guidelines can be used to teach severe CHI patients
to develop a new automatic skill. (JINS, 2001,
