New preprint!!!. @TianHWang shows that attention influences sensorimotor adaption by defining the context for learning. Check it out! 👇.
biorxiv.org
Movement errors are used to continuously recalibrate the sensorimotor map, a process known as sensorimotor adaptation. Here we examined how attention influences this automatic and obligatory learning...
🚨 New Preprint Alert! 🚨Here we've revealed a novel mechanism of how attention shapes sensorimotor learning across 8 experiments. Key findings:.

New review paper now published in @eLife!. @tsay_jonathan and colleagues propose a new framework for strategy use in motor learning. Check it out! 👇.
elifesciences.org
The 3R framework outlines three fundamental processes in motor learning and provides a novel perspective on understanding how we acquire, adapt, and retain complex motor skills.
Our paper on "Fundamental processes in sensorimotor learning: Reasoning, refinement, and retrieval" has been posted on @eLife. I am thankful for our team/reviewers/editors for their feedback in refining our 3R framework. Let us know what you think!.

Second preprint this week, and no less exciting!!!. Elizabeth Cisneros and colleagues provide a comprehensive examination of aging and motor learning. Check it out! 👇.
biorxiv.org
Deterioration in motor control is a hallmark of aging, significantly contributing to a decline in quality of life. More controversial is the question of whether and how aging impacts sensorimotor...
Question: How does #aging impact #motor #learning? . Answer: Aging enhances implicit learning, but reduces explicit motor learning. New @biorxivpreprint: Amazing work led by Elizabeth Cisneros! . S. Karny, @ivrylab @BerkeleyPsych @cmupsych @cmuneurosci.

New preprint!!!. @yifeichen2023 and colleagues examined the role of symbolic feedback in motor adaptation. Check it out! 👇.
biorxiv.org
Motor adaptation – the process of reducing motor errors through feedback and practice – is an essential feature of human competence, allowing us to move accurately in dynamic and novel environments....
In a series of experiments involving over 400 human participants, we found that motor adaptation was reduced by symbolic compared to sensory feedback. 🧵.@yifeichen2023 @sabrinabram @ivrylab.

The human cerebellum shows fMRI activity for many tasks – however, the inputs from the neocortex are upregulated in a task-dependent manner when cerebellar computation is required.

New preprint!!!. @avraham_guy & @ivryrich address the question of why implicit motor adaptation shows attenuation upon relearning (anti-savings). Check it out! 👇.
biorxiv.org
Savings refers to the gain in performance upon relearning a task. In sensorimotor adaptation, savings is tested by having participants adapt to perturbed feedback and, following a washout block...
In a new preprint, @ivryrich and I dive into the mechanism underlying attenuation upon relearning in sensorimotor adaptation. TLDR: Interference. But you should read - there is a surprising twist 🙂. Details 👇. 1/13.

New paper in @PLOSCompBiol!!!. Prevailing models of motor adaptation state that an increase in environmental (or perturbation) variability attenuates implicit learning. @TianHWang and colleagues provide multiple lines of evidence challenging this view. Check it out! 👇.
Thrilled to share our latest paper published in @PLOSCompBiol! Our work challenges prevailing theories in motor learning. Through various sensorimotor experiments, the implicit system is NOT modulated by error consistency.

New paper published in @JOCN_Journal!!!. @tsay_jonathan and colleagues examined how the relevance of the feedback in a motor task influences implicit changes in movements. Check it out!.

Abstract. Given that informative and relevant feedback in the real world is often intertwined with distracting and irrelevant feedback, we asked how the relevancy of visual feedback impacts implicit...
Question: Does the relevance of visual feedback influence how we subconsciously correct for errors in our movement?. Answer: Yes! . In our paper in @JOCN_Journal, we showed that *implicit* motor adaptation is modulated by the relevance of visual feedback.

New preprint!!!. @TianHWang and colleagues dive into movement biases. Check it out!.
Where does the motor bias originate? In this new preprint with @tsay_jonathan @rmhead @ivrylab, we show motor biases arise from the transformation of eye-centered visual information (where is the target) into hand-centric proprioceptive space during motor planning.

New paper in @CurrentBiology!!!. @TianHWang and colleagues identified the optimal timing of the feedback to drive motor adaptation, and it is not necessarily what you thought. Check it out!.

Delayed visual feedback is known to disrupt sensorimotor adaptation. Wang et al. show that temporally advancing feedback relative to movement position enhances adaptation. Thus, learning is maximized...
Check out our latest @CurrentBiology paper on how to optimize the feedback for motor learning! Providing participants with their hypothetical movement endpoint, before completing the action, boosts learning outcomes over traditional feedback.
