Also, manipulating implicit changes in the responses to the errors by delaying the feedback did not influence error sensitivity under consistent perturbations.
Unlike participants that deliberately counteract the rotation, participants that are asked to ignore the rotated cursor and move directly to the target (eliminating strategy use) do not exhibit significant changes in error sensitivity between low and high consistency conditions.
Motor learning involves both explicit and implicit processes. Thus, we asked whether the consistency-driven effects on error sensitivity modulations are due to the use of explicit control strategies, implicit changes in behavior, or both.
We first replicated these findings here by comparing learning to visuomotor rotation that is presented in random (low consistency) or random walk (high consistency) sequences: People showed higher error sensitivity for the random walk sequence.
Previous works (e.g., https://t.co/qhd5zfd6wV and https://t.co/AD6kEou0hd) showed that when external perturbations are consistent, the sensorimotor system increases its sensitivity to errors, which enables better learning.

Here is a summary…
Happy New Year! Always great to celebrate with lab members and collaborators - we wish you all a year of discovery, hard work, and many smiles @amitmil@uri_netz@bengurionu@Biomed_BGU
Our paper is out! After playing pong with a delayed paddle, humans exhibit hypermetric blind movements, suggesting a representation of the delay as a spatial gain change in visuomotor mapping. @SfNJournals@RazWazziLeib@shmuelof@smivtweet@NiskyLab https://t.co/U7gSh1Tkwr
Excited to get some pre-anodized RAVEN images from @3dsystems for our customers @homalm at @UVA and @anjalijai@QUT! This is the fifth RAVEN build and its starting to get real. These parts will be involved in great surgical research before we know it!
