Sequential responding to arabic numerals with wild cards by the chimpanzee (Pan troglodytes)

  title={Sequential responding to arabic numerals with wild cards by the chimpanzee (Pan troglodytes)},
  author={Masaki Tomonaga and Tetsuro Matsuzawa},
  journal={Animal Cognition},
One adult female chimpanzee (Pan troglodytes) was trained to respond serially to three arabic numerals between 1 and 9, presented on a cathode-ray-tube (CRT) screen. To examine the factors affecting her sequential responding behavior, wild-card items were added to the three-item sequences. When this wild-card item remained until the subject responded to the last numeral (i.e., the terminator condition), her response to the terminator at each point of the sequence was controlled by the ordinal… CONTINUE READING
