Abstract:
Studies have shown that explicit strategies make a significant contribution to visuomotor adaptation. However, little attention has been given to potential unconscious cognitive biases in these strategies, despite that they involve a sequence of cognitive decision-making processes. To reveal the possible cultural biases involved in motor learning, we compared Norwegian and Japanese participants in a visuomotor adaptation task using a verbal report paradigm. The results showed that Japanese participants aimed at locations more deviant from the target to account for rotated visual feedback. Additionally, a greater proportion of Japanese participants changed their aiming direction more frequently than Norwegian participants, even after successfully hitting the target. However, both groups showed similar behavioral performance, with comparable reaching accuracy and aftereffect amplitudes. These results suggest that the explicit component, which is estimated based on verbal reports, includes cognitive biases. The present study challenges the assumption of universality of motor learning among cultures.

行動実験でデータを集める方なら誰しも,実験対象者(個体)の「課題の取り組み方・課題への姿勢」について思いを巡らせたことがあるのではないでしょうか。この研究では,運動学習実験における「意識的戦略」の定量化手法に着目しました。従来,運動学習に関与する潜在学習と意識的戦略はいずれもヒト普遍的であると考えられてきました。本研究で日本人およびノルウェー人の大学生を対象に視覚運動順応課題を実施したところ,実際の運動成績には群間で差がみられなかった一方で,課題中の戦略のとり方は群間で異なることが示されました。これらの結果は,運動学習プロセスにおける意識的戦略に文化差がないことを前提とした議論の再検討を促します。
