Is motor adaptation a form of associative learning? In a new paper, now published in @eLife, we show that we can create associations between movement errors and arbitrary cues! With @IPALab, @AssafBreska, @ivryrich and @smickdougle elifesciences.org/articles/7… #tweeprint👇

Contextual effects in sensorimotor adaptation adhere to associative learning rules

Core associative learning phenomena that are observed in studies of eyeblink conditioning are also observed in sensorimotor adaptation, pointing to a common framework for these distinct cerebellar-...

Interference Underlies Attenuation upon Relearning in Sensorimotor Adaptation

Savings refers to the gain in performance upon relearning. In sensorimotor adaptation, savings is tested by having participants adapt to perturbed feedback and, following a washout block during which...

In Exp 5 we show that prolonged experience with baseline feedback produces attenuated adaptation. This is strikingly similar to latent inhibition, and consistent with our other evidence suggesting that motor adaptation is a form of associative learning. elifesciences.org/articles/7…

🚨 New preprint alert! Attention isn’t always helpful. We found that dividing attention can boost implicit adaptation—if timed right. A twist on the idea that distraction always impairs performance. w @benmillermills @TimCarroll_UQ biorxiv.org/content/10.1101/… #biorxiv_neursci

Benefits of dual-tasking on implicit sensorimotor adaptation

Attention plays a crucial role in maintaining precision and effectiveness in goal-directed actions. Although there is evidence that dividing attention across tasks impairs performance in various...

How does the motor system enable dexterous finger movement, and how does it recover after a stroke? Many questions remain, but in this ANN model designed to "mimic" physiological insights from humans and NHPs, we identified novel predictions: iopscience.iop.org/article/1…
