Predicted and observed GPs for weighted combination models in experiments 2 and 3. A: observed gain in single-gain (black trace with circles, gain 0.8; black trace with triangles, gain 0.6) and double-gain (black trace with squares; gray shading, ±1SD) conditions in experiment 2; gain predicted by independent spatial weighting model (dotted gray trace); gain predicted by relative spatial weighting model (solid gray trace). Vertical dashed lines, training directions. B: observed gain in single-gain (black trace with circles, gain 0.8; black trace with triangles, gain 1.5) and double-gain (black trace with squares; gray shading, ±1SD) conditions in experiment 3; gain predicted by independent spatial weighting model (dotted gray trace); gain predicted by relative spatial weighting model (solid gray trace).
