The effects of erroneous knowledge of results on transfer of anticipation timing.

Previous research has shown that erroneous knowledge of results (KR) biased subjects' performance during retention trials for an anticipation timing task (Buekers, Magill, & Hall, 1992). The present experiment extended that work by investigating effects on novel transfer. During acquisition, three groups received either correct KR, erroneous KR, or 50 trials of correct KR followed by 25 trials of erroneous KR, where KR was the anticipation timing error in milliseconds. Erroneous KR was the actual timing error + 100 ms. One day later, subjects performed 15 trials without KR at each of two novel trackway speeds. Results showed that the bias acquired by the All-Erroneous KR condition during acquisition generalized across novel trackway speeds while the Mixed-Correct and Erroneous KR condition yielded a nonsignificant trend toward a response bias.
