Teaching memory-impaired people to touch type: the acquisition of a useful complex perceptual-motor skill.

This study provides ecological validity for laboratory findings that people with memory difficulties following brain injury can learn new skills. This was done by testing the acquisition of a useful real-world perceptual-motor skill. Using a conventional computer software training package supplemented by one-to-one coaching, a woman with severely impaired memory and a man with poor memory learned to touch type. They achieved the initial criterion of 20 wpm with over 90% accuracy; reached a top speed of 30 wpm and retained their skill a year later. The memory-impaired participants received short sessions of distributed practice and as far as possible were taught under error-free learning conditions. Their performance was broadly comparable with that of two non-memory-impaired comparison participants in terms of acquisition, consolidation and transfer, speed and accuracy, and retention.
