Hand asymmetries in interresponse intervals during rapid repetitive finger tapping.
Interresponse intervals (IRIs) were recorded as 8 right-handed male subjects tapped a key separately with the index finger of each hand as fast as possible for twenty 10-s runs. Frequency distributions of the IRIs produced by each hand showed that the shorter mean IRI that is usually reported for preferred-hand tapping is a result of a systematic production of shorter IRIs by the preferred hand. It is not secondary to inflation of the mean IRI of the non-preferred hand by the sporadic occurrence of long IRIs.
