Table 2.

Proportion of variance accounted for and parameters of Equation 1 for the 1-hr and 23- hr deprivation phases for each pigeon in Experiment 2. R_k² indicates the proportion of variance accounted for by Equation 1 with s = 1.0, and R_k,s² indicates the proportion of variance accounted for by Equation 1 with s as a free parameter in cases where s was significantly different from 1.0 (Pigeon 81 in the 1-hr deprivation phase and Pigeon 82 in the 23-hr deprivation phase).
