  1. Note. The label of each hypothesis stipulates the constraints on mean parameter estimates. c is the number of free parameters in each hypothesis; RSS is the residual sum of squares from model fitting. For all hypotheses, the number of observations was n = 90. See Equation 2 and text for computation of ΔAICc. Hypotheses are arranged according to ΔAICc within each epoch. Hypotheses with ΔAIC = 0 were selected for parameter estimation.
