通过一系列实验考察了竞争对视频格式任务绩效的影响。两只恒河猴（Macaca mulatta）被训练操纵操纵杆射击计算机屏幕上的移动目标。通过要求两只动物向同一目标射击，并在每次试验中只奖励首先击中目标的动物，使任务具有竞争性。竞争性的任务产生了显着的和强大的速度-精度权衡性能。猴子在有争议的试验中击中目标的时间明显少于无争议的试验。然而，在有争议的审判中，与无争议的审判相比，他们需要更多的子弹才能击中目标。在无争议的审判中采用各种增援时间表时，这种效果没有改变。这支持了竞争对表现的影响，这一点得到了这里提出的行为对比的其他发现的进一步支持。
The effects of competition on performance of a video-formatted task were examined in a series of experiments. Two rhesus monkeys (Macaca mulatta) were trained to manipulate a joystick to shoot at moving targets on a computer screen. The task was made competitive by requiring both animals to shoot at the same target and by rewarding only the animal that hit the target first each trial. The competitive task produced a significant and robust speed-accuracy trade-off in performance. The monkeys hit the target in significantly less time on contested than on uncontested trials. However, they required significantly more shots to hit the target on contested trials in relation to uncontested trials. This effect was unchanged when various schedules of reinforcement were introduced in the uncontested trials. This supports the influence of competition qua competition on performance, a point further bolstered by other findings of of behavioral contrast presented here.
