N2 - We investigated intermanual transfer and longterm retention of practice-related perceptual learning in the domain of tactile hyperacuity. Subjects discriminated a row of three dots in which the central dot was offset laterally from a row without such offset. Performance at the right index fingerpad improved with practice. Practice effects transferred essentially completely to the left index fingerpad. When tested some months later at the right index fingerpad, long-term retention of learning was limited and further practice was required to stabilize discrimination thresholds. Intermanual transfer of tactile learning appears to be a general phenomenon, while long-term retention appears to be limited in hyperacuity tasks.
