Patterns of generalization after single- and double-gain training in experiment 1. Plotted is gain in TEST block as a function of target direction (generalization pattern [GP]). A: observed gain (Go) vs. target direction (relative to training direction) in adaptation to single imposed gain of 1.5. B: observed gain vs. relative target direction after adaptation to single gain of 0.8. C: observed gain vs. standardized target direction (see methods) in double-gain condition (solid black trace with squares) imposed gain 1.5 in direction −150° and 0.8 in direction 60°. Horizontal axis range is >360° to better illustrate shape of double-gain GP. Thin traces indicate double-gain GPs for individual subjects. Dashed traces with triangles and circles show single-gain GPs for gains 1.5 and 0.8, respectively (same traces as in A and B, replotted against standardized target direction). In all panels: vertical dashed lines, training directions; gray shading, ±1SD.
