The Role of Variability in Motor Learning by Dhawale, Ashesh K, Smith, Maurice A, Ölveczky, Bence P

“…Trial-to-trial variability in the execution of movements and motor skills is ubiquitous and widely considered to be the unwanted consequence of a noisy nervous…”

Implicit adaptation compensates for erratic explicit strategy in human motor learning by Miyamoto, Yohsuke R., Wang, Shengxin, Smith, Maurice A.

“…Sports are replete with strategies, yet coaching lore often emphasizes ‘quieting the mind’, ‘trusting the body’ and ‘avoiding overthinking’ in referring to the…”

Error Correction, Sensory Prediction, and Adaptation in Motor Control by SHADMEHR, Reza, SMITH, Maurice A, KRAKAUER, John W

“…Motor control is the study of how organisms make accurate goal-directed movements. Here we consider two problems that the motor system must solve in order to…”

Temporal structure of motor variability is dynamically regulated and predicts motor learning ability by Wu, Howard G, Miyamoto, Yohsuke R, Castro, Luis Nicolas Gonzalez, Ölveczky, Bence P, Smith, Maurice A

“…Here the authors report that higher levels of task-relevant motor variability predict faster learning both across individuals and across tasks in two different…”

Interacting adaptive processes with different timescales underlie short-term motor learning by Smith, Maurice A, Ghazizadeh, Ali, Shadmehr, Reza

“…Multiple processes may contribute to motor skill acquisition, but it is thought that many of these processes require sleep or the passage of long periods of…”

Motor planning under uncertainty by Alhussein, Laith, Smith, Maurice A

“…Actions often require the selection of a specific goal amongst a range of possibilities, like when a softball player must precisely position her glove to field…”

A double dissociation between savings and long-term memory in motor learning by Hadjiosif, Alkis M, Morehead, J Ryan, Smith, Maurice A

“…Memories are easier to relearn than learn from scratch. This advantage, known as savings, has been widely assumed to result from the reemergence of stable…”

Shared Internal Models for Feedforward and Feedback Control by Wagner, Mark J, Smith, Maurice A

“…A child often learns to ride a bicycle in the driveway, free of unforeseen obstacles. Yet when she first rides in the street, we hope that if a car suddenly…”

The Decay of Motor Memories Is Independent of Context Change Detection by Brennan, Andrew E, Smith, Maurice A

“…When the error signals that guide human motor learning are withheld following training, recently-learned motor memories systematically regress toward untrained…”

Motor memory is encoded as a gain-field combination of intrinsic and extrinsic action representations by Brayanov, Jordan B, Press, Daniel Z, Smith, Maurice A

“…Actions can be planned in either an intrinsic (body-based) reference frame or an extrinsic (world-based) frame, and understanding how the internal…”

Environmental Consistency Determines the Rate of Motor Adaptation by Gonzalez Castro, Luis Nicolas, Hadjiosif, Alkis M., Hemphill, Matthew A., Smith, Maurice A.

“…The motor system has the remarkable ability not only to learn but also to learn how fast it should learn. However, the mechanisms behind this ability are not…”

Bayesian and "anti-Bayesian" biases in sensory integration for action and perception in the size-weight illusion by Brayanov, Jordan B, Smith, Maurice A

“…Which is heavier: a pound of lead or a pound of feathers? This classic trick question belies a simple but surprising truth: when lifted, the pound of lead…”

Reduction in learning rates associated with anterograde interference results from interactions between different timescales in motor adaptation by Sing, Gary C, Smith, Maurice A

“…Prior experiences can influence future actions. These experiences can not only drive adaptive changes in motor output, but they can also modulate the rate at…”

Primitives for Motor Adaptation Reflect Correlated Neural Tuning to Position and Velocity by Sing, Gary C., Joiner, Wilsaan M., Nanayakkara, Thrishantha, Brayanov, Jordan B., Smith, Maurice A.

“…The motor commands required to control voluntary movements under various environmental conditions may be formed by adaptively combining a fixed set of motor…”

The binding of learning to action in motor adaptation by Gonzalez Castro, Luis Nicolas, Monsen, Craig Bryant, Smith, Maurice A

“…In motor tasks, errors between planned and actual movements generally result in adaptive changes which reduce the occurrence of similar errors in the future…”

Temporal specificity of the initial adaptive response in motor adaptation by Joiner, Wilsaan M, Sing, Gary C, Smith, Maurice A

“…Repeated exposure to a novel physical environment eventually leads to a mature adaptive response whereby feedforward changes in motor output mirror both the…”
