TABLE II
Mean durations (with SD) of approach (s) to each of nine test stimuli, T1—T9, for birds with anterior (Al), posterior lesions (Pl) and
sham controls (C). The C group does not approach for as long as the two Iesioned groups following T2 (slow trill); The means are
also shown for the two homogeneous groups T1 T3, Ts, and T4, T,, T8, where the Pl group approaches for longer than the Al or C
groups
