Motor Adaptation Decay Data from Reaching Experiments

A collection of experimental data from a motor adaptation study where subjects made reaching movements under force perturbations dependent on limb position or velocity. It includes measurements of feedforward motor output decay from error-clamp trials, used to analyze the relative stability of motion state-dependent learning. The data was generated by Eghbal A. Hosseini and published in 2019.

Use Cases

• Model the temporal decay of feedforward motor output from error-clamp trial data.
• Compare the stability of adaptation memories based on limb position versus velocity motion states.
• Analyze gain-space trajectories for the learning and decay phases of motor adaptation.
• Simulate motor adaptation behavior for different learning goals using position-dependent and velocity-dependent gain parameters.

Strengths

• Data originates from controlled human subject experiments on motor adaptation.
• Includes measurements from error-clamp trials designed to isolate feedforward motor output.
• Published under the permissive CC0 1.0 public domain license.
• Dataset was last updated and made available in 2019.

Limitations

• Specific sample size (number of subjects or trials), column definitions, and data volume are unknown.
• Data scope is limited to a specific laboratory motor adaptation paradigm, limiting generalizability.
• The dataset's structure, file formats, and completeness are not described.
