老鼠按下诺伊斯颗粒的杠杆或按多个时间表提供的甜炼乳强化剂的钥匙。两个实验中的会话长度和基线强化率有所不同。在课程的早期阶段，反应率增加，然后反应和强化物以及所有受试者和自变量值的反应率下降。会议期间响应率的变化有时会超过 500%。当受试者按照多变量间隔 1 分钟可变间隔 1 分钟时间表进行响应时，无论会话持续时间长短，响应率在会话开始后约 20 分钟达到峰值。较长会话的函数比较短会话更平坦。与较高强化率相比，较低强化率的函数更平坦、更对称，并且达到峰值较晚。该功能在训练初期就出现了，进一步的经验移动并降低了其峰值。与强化相关的变量比与响应相关的变量对该功能的某些方面施加了更多的控制。这些会话内的响应模式可能对实验设计和理论化产生根本性的影响。
Rats pressed levers for Noyes pellets or keys for sweetened condensed milk reinforcers delivered by multiple schedules. Session length and baseline rates of reinforcement were varied in two experiments. Rates of responding increased during the early part of the session and then decreased for both responses and reinforcers, as well as for all subjects and values of the independent variables. Changes in response rates across the session sometimes exceeded 500%. Response rates peaked approximately 20 min after the beginning of the session, regardless of session duration, when subjects responded on a multiple variable interval 1-min variable interval 1-min schedule. The function was flatter for longer sessions than it was for shorter sessions. The function was flatter, more symmetrical, and peaked later for lower rates of reinforcement than for higher rates of reinforcement. The function appeared early in training, and further experience moved and reduced its peak. Variables related to reinforcement exerted more control over some aspects of this function than did variables related to responding. These within-session patterns of responding may have fundamental implications for experimental design and theorizing.
