Abstract
Following either variable-interval or fixed-interval training. 20 rats received both 0.5 and 2.0 mg/kg of amphetamine. For both schedules, amphetamine decrease response rates of high-rate subjects and increased those of low-rate subjects. Within-subject analysis of fixed-interval rates revealed the same rate-dependent effect. It is suggested that the between-subject and within-subject effects may have the same basis.
摘要
在可变间隔或固定间隔训练后，20只大鼠分别接受了0.5毫克/千克和2.0毫克/千克的苯丙胺。对于这两种训练安排，苯丙胺降低了高反应率受试者的反应率，提高了低反应率受试者的反应率。对固定间隔率的受试者内分析显示了相同的率依赖性效应。研究表明，受试者间和受试者内效应可能具有相同的基础。
