Marmosets were trained on a task involving simultaneous and successive visual discrimination performance where responses were required on all trials. Performance of this task was not affected by low doses of amphetamine. From this it is concluded that amphetamine does not cause a narrowing of attention and that the disruptive effect of amphetamine on the "go-no go" successive discrimination task already reported is due to a loss of response inhibition rather than to difficulties in the recognition of stimuli presented without a comparison stimulus.
狨猴接受了一项任务训练，该任务涉及同时性和继时性视觉辨别表现，所有试验都需要做出反应。低剂量苯丙胺对这项任务的表现没有影响。由此得出结论，苯丙胺不会导致注意力变窄，并且苯丙胺对先前报道的“去 - 不去”继时辨别任务的干扰作用是由于反应抑制的丧失，而不是由于在没有比较刺激的情况下识别呈现的刺激存在困难。
