The “Not Letting Go” phenomenon: accuracy instructions can impair behavioral and metacognitive effects of implicit learning processes

摘要

One major assumption in the field of implicit learning is that implicit learning processes directly affect performance without further top-down control (e.g., Destrebecqz and Cleeremans 2003). In three related experiments, the authors tested the so-called “Not Letting Go Phenomenon” (Schneider and Fisk in J Exp Psychol Learn Mem Cogn 8:261–278, 1982); that is, the assumption that accuracy instructions might impair the effect of implicit learning processes during skill acquisition. Results of Experiment 1 show that accuracy instructions can impair both, the behavioral and metacognitive effects of implicit learning. Experiments 2 and 3 indicate that this impairment is due more to an impairment of the performance effects of implicit learning processes than to a direct impairment of the learning processes, per se. While these results are in accordance with recent findings in skill acquisition showing that monitoring processes impede experts’ performance, they seem to contradict the above mentioned assumption that implicit learning processes directly affect performance.
