A: bias measures from empirical data (right, left, and bimanual) and predictions (Bi50, BiMLE, BiMLEcorr, SwitchRand, SwitchWeight, and UniMin). ***Reliably different means (all of which were reliable with P < 0.001). B: acuity measures from empirical data (right, left, and bimanual) and predictions (Bi50, BiMLE, BiMLEcorr, SwitchRand, SwitchWeight, and UniMin). *Reliable difference (P < 0.05).
