Abstract
Sixty-tour Ss were required to learn a three-dimensiona, binary choice concept identification task with either (l)a fixed 2-sec postfeedback interval (PFI) or (2) a free-choice PFI. All Ss were allowed to determine their own response interval (RI). The results indicated no differences in RI latencies between these groups. However, RI latencies were longer when the stimuli were more complex. PFI latencies did not vary as a function of stimulus complexity. Both RI and PFI latencies were longer following errors and tended to be shorter during reversal-shift transfer task. The free-choice PFI Ss reached criterion in fewer trials than did the 2-sec PFI Ss. These results were interpreted as supporting a hypothesis that Ss eliminate hypotheses during the PFI and select hypotheses during the RI.
