Single alternation behavior was studied in a Pavlovian aversive shuttleresponse situation using goldfish. Independent groups of fish were given either a fixed interval between alternating reinforced (R) and nonreinforced (N) trials or were given differential temporal information between trials. Although all groups exhibited higher response probabilities on reinforced than on nonreinforced trials, goldfish receiving a short interval (10 s) following R trials and a long interval (60 s) following N trials (R'oN60d) emonstrated significantly superior alternation performance compared with subjects receiving a fixed intertrial interval (R"5N35o)r a long interval following R trials and a short interval following N trials (R6ONLoT)h. e alternation performance exhibited by the R'0N60 group was shown to be equivalent to that of subjects receiving standard color discrimination training. However, the alternation performance in group R35N3s5h owed a great deal of withinsubject variability and raises questions concerning the elusive nature of alternation using Pavlovian conditioning procedures.
