Short-term memory in the macaque monkey: cue-reproducing response during delay interval.
The effects of cue-reproducing responses of macaque monkeys during the delay interval of a delayed response task were examined in several situations. The monkeys showed better performance in the cue-reproducing than the nonreproducing condition. When the monkeys were exposed to choices between two keys, responses to either key reproduced the cue, the monkeys selected the cue-reproducing key only when a "mnemonic device" was available. Cue-reproducing responses of the monkeys were suggested to correspond with human rehearsal behaviors. Codes and coding responses in delayed response performance were also discussed.
