The intention superiority effect in motor skill learning.

Three experiments were conducted to determine if the intention to perform motor sequences in the future results in similar patterns of activation and inhibition as observed for verbal scripts. In Experiments 1 and 2, intention was induced by informing one group that they would be tested on the tasks following acquisition; the other group was not informed of the retention test. Recognition tests administered prior to and after the retention test indicated a strong intention superiority effect. However, intention instructions provided either at the end of acquisition (Experiment 1) or before acquisition (Experiment 2) failed to impact acquisition or retention performance of the motor sequences, but did influence the latency of responding on the retention test. Experiment 3 was designed to replicate the results of Experiments 1 and 2 using a within-subjects design and extend these findings to observation. The results indicated that intention instructions resulted in a strong intention superiority effect for both the physical and observational practice participants, but the performance on the intentional tasks was enhanced only for the observational practice group.
