Development of appropriate sensorimotor recalibration for a de novo skill

After up to a month of training on novel sensorimotor mappings, implicit recalibration flexibly reconfigures to match each mapping, including mirror reversals and large rotations.

• Why it matters: Prior work suggested implicit recalibration is inflexible and can remain maladaptive when new mappings are required for a de novo skill.
• What they did: Participants trained for up to a month across tasks with novel mappings; emphasizing feedforward planning rather than feedback control was sufficient to induce reconfiguration of sensory predictions and error correction policy.
• The result: Implicit recalibration became context-specific, with minimal interference when switching mappings, demonstrating flexible adaptation during skill acquisition.
