Generalization from Left or Right to Center. The fields are translation invariant in both hand and joint coordinates.A, Subjects practiced in the null field, then learned field B₁ at Right, and were then tested at Center (C) in field B₁(bin size = 64 movements; mean ± SEM). Performance at Center was significantly better than that of naive controls. B, Subjects learned field B₂ at Left and were tested at Center on B₂. Performance at Center was significantly better than that of naive controls.
