The effects of different physical-effort requirements on behavioral resistance to change were examined with undergraduate students engaging in a computer task for points exchangeable for money. In Baseline, button pressing was maintained on a multiple variable interval (VI) 45-s VI 45-s schedule of reinforcement with two physical-effort requirements: 10 N in the Low-Effort Component and 50 N in the High-Effort Component. In Test, button pressing was disrupted by a multiple extinction (EXT) EXT schedule plus anagrams as a concurrent task for five participants. For other two participants, button pressing was disrupted only by a multiple EXT EXT in one test, and both disruptors were implemented together in the second test. Baseline and Test conditions were replicated in an ABAB design. Resistance to change was greater in the presence of discriminative stimuli associated with the Low-Effort Component to six participants during the first test and to four participants during the second test. The present findings suggest differences in physical-effort can contribute to differences in resistance to change.

作为人类不同体力需求的函数的对变化的抵抗

研究不同体力要求对改变行为抵抗力的影响，本科生参与计算机任务以换取积分。在 Baseline 中，按钮按压保持在多变量间隔 (VI) 45 秒 VI 45 秒强化计划中，有两个体力要求：低强度部分为 10 N，高强度部分为 50 N。在测试中，按钮按下被多重灭绝 (EXT) EXT 计划加上字谜作为五个参与者的并发任务中断。对于其他两名参与者，在一次测试中，按钮按下仅被多个 EXT EXT 干扰，而在第二次测试中，两个干扰器一起实施。在 ABAB 设计中复制了基线和测试条件。在第一次测试中，六名参与者和第二次测试中的四名参与者在存在与低努力部分相关的歧视性刺激时，对改变的抵抗力更大。目前的研究结果表明，体力劳动的差异可能导致对变化的抵抗力的差异。
