Abstract

Research Objectives: Fast learning of a novel motor sequence occurs across trials for a given motor task (Karni et al., 1998). Furthermore, two similar motor sequences can interfere with each other when executed within a short delay because motor memories are unstable initially (e.g. Shadmehr & Brashers-Krug, 1997). With a longer delay, interference decreases because motor memory consolidation occurs. This study investigated whether fast learning and interference would occur with two consecutive different motor tasks. It was hypothesised that fast learning would be evident for both tasks across counterbalanced and blocked trials, and that there would be interference between the two tasks executed consecutively within a short delay only.

Design/Method:The tasks consisted of drawing a square pyramid and doing a simple addition on a Chinese abacus, with three trials in each. The time taken to perform each trial was measured. One group of participants performed both tasks together in alternate trials (short delay). Another group completed each task separately on different days (longer delay).

Results/Conclusion:Fast learning was elicited as a decreased execution time across trials for both tasks in both groups. Interference from the memory for the first task was observed only in group one.
