Demonstrating Parallel Adaptation: How Switching between Two Virtual Bodies with Different Perspectives Enables Dual Motor Adaptation

We demonstrate a dual-motor adaptation over 2 virtual bodies with opposite visuomotor rotation (+ 15° and − 15°). A related study explored the effect of view perspective (1st person view perspective, 1pp, and 3rd person view perspective, 3pp) on a dual motor adaptation behavior. They showed that (1) in 1pp, the adaptation is explicit, while in 3pp, the adaptation is implicit, and (2) the implicit adaptation led to a better dual adaptation. Here we let the participants experiment with explicit and implicit dual motor adaptation by doing a reaching task in 1pp and then in 3pp. We present an ad-hoc motor adaptation score and discuss which adaptation behavior led to a better dual adaptation.
