Eliminating Direction Specificity in Visuomotor Learning.
UNLABELLED The generalization of learning offers a unique window for investigating the nature of motor learning. Error-based motor learning reportedly cannot generalize to distant directions because the aftereffects are direction specific. This direction specificity is often regarded as evidence that motor adaptation is model-based learning, and is constrained by neuronal tuning characteristics...
متن کاملTuning curves for movement direction in the human visuomotor system.
Neurons in macaque primary motor cortex (M1) are broadly tuned to arm movement direction. Recent evidence suggests that human M1 contains directionally tuned neurons, but it is unclear which other areas are part of the network coding movement direction and what characterizes the responses of neuronal populations in those areas. Such information would be highly relevant for the implementation of...
متن کاملVisuomotor Learning Using Image Manifolds
Vision provides us with much information about distal spaces, and enables us to formulate expectations about how objects move. In this work, we consider how images, together with motor and performance data, can be used to form ”maps” or a holistic view of any motion. For example if the learner knows how to throw a ball, it may be able to use the map to see that it also applies to kicking, or ca...
متن کاملIdentifying Learning in a Visuomotor Skill
—We develop a framework for model selection, using structured and unstructured linear time invariant control models, to describe human motor behavior for individual trials of a compensatory tracking experiment. We develop new metrics for quantifying performance and learning across trials using state space model parameters. Changes in metric parameter values obtained from the control model estim...
متن کاملLocation and direction specificity in motion direction learning associated with a single-level method of constant stimuli
Recent studies reported significantly less location specificity in motion direction learning than in previous classical studies. The latter performed training with the method of constant stimuli containing a single level of direction difference. In contrast the former used staircase methods that varied the direction difference trial by trial. We suspect that extensive practice with a single dir...
