Abstract

Four squirrel monkeys were trained for 88 sessions on a multiple schedule that included two DRL 10 sec. components. In one, timing responses were reinforced by the presentation of sucrose pellets; in the other, by the offset of aversive noise for 20 sec. (1) Timing was better under positive reinforcement. (2) Noise was an effective negative reinforcer. (3) Timing under positive reinforcement did not improve markedly from about the 25th to about the 88th session, but timing under negative reinforcement worsened. (4) The noise-offset contingencies may have opposed the development of accurate timing.
