Research suggests that repetitive reinforcers wane in their ability to maintain operant behavior in a manner consistent with habituation. Weaker reinforcers, including sensory stimuli common in human work, may be most impacted by repetition. The present research examined within-session operant responding patterns for visual stimuli in humans from two experiments assessing multiple characteristics of habituation. In Experiment 1, declines in reinforced responding were assessed and stimulus specificity was evaluated to test habituation's contribution to these declines. Seventy-three participants completed two visits, both including a reinforcement paradigm using pictures. With repetition, operant responding declined. The stimulus specificity manipulation did not enhance responding, suggesting that habituation did not contribute to response declines. Several methodological concerns may have contributed to the absence of a stimulus specificity effect. Experiment 2 assessed a separate habituation characteristic, rate of stimulation, to address these methodological concerns and further evaluate habituation. Twenty-eight participants completed the reinforcement paradigm over three visits. Decline in responding was partially supported, but the rate of stimulation did not alter declines. In sum, habituation's contribution to within-session declines for sensory reinforcers was not evident in either experiment. These results suggest that assessment of habituation of sensory reinforcers in humans may require parametric evaluation.

人类对感觉刺激的操作性反应习惯的初步评估

研究表明,重复性强化物以与习惯一致的方式维持操作性行为的能力减弱。较弱的强化物,包括人类工作中常见的感官刺激,可能受重复影响最大。本研究从两个评估习惯的多种特征的实验中检查了人类视觉刺激的会话内操作性反应模式。在实验 1 中,评估了强化反应的下降,并评估了刺激特异性以测试习惯对这些下降的贡献。73 名参与者完成了两次访问,都包括使用图片的强化范式。随着重复,操作性反应下降。刺激特异性操作并没有增强反应,表明习惯不会导致反应下降。几种方法学问题可能导致缺乏刺激特异性效应。实验 2 评估了一个单独的习惯特征,即刺激率,以解决这些方法问题并进一步评估习惯。28 名参与者在 3 次访问中完成了强化范式。反应下降得到部分支持,但刺激率并未改变下降。总之,习惯对感觉强化剂的会话内下降的贡献在这两个实验中都不明显。这些结果表明,评估人类感觉强化剂的习惯可能需要参数评估。几种方法学问题可能导致缺乏刺激特异性效应。实验 2 评估了一个单独的习惯特征,即刺激率,以解决这些方法问题并进一步评估习惯。28 名参与者在 3 次访问中完成了强化范式。反应下降得到部分支持,但刺激率并未改变下降。总之,习惯对感觉强化剂的会话内下降的贡献在这两个实验中都不明显。这些结果表明,评估人类感觉强化剂的习惯可能需要参数评估。几种方法学问题可能导致缺乏刺激特异性效应。实验 2 评估了一个单独的习惯特征,即刺激率,以解决这些方法问题并进一步评估习惯。28 名参与者在 3 次访问中完成了强化范式。反应下降得到部分支持,但刺激率并未改变下降。总之,习惯对感觉强化剂的会话内下降的贡献在这两个实验中都不明显。这些结果表明,评估人类感觉强化剂的习惯可能需要参数评估。28 名参与者在 3 次访问中完成了强化范式。反应下降得到部分支持,但刺激率并未改变下降。总之,习惯对感觉强化剂的会话内下降的贡献在这两个实验中都不明显。这些结果表明,评估人类感觉强化剂的习惯可能需要参数评估。28 名参与者在 3 次访问中完成了强化范式。反应下降得到部分支持,但刺激率并未改变下降。总之,习惯对感觉强化剂的会话内下降的贡献在这两个实验中都不明显。这些结果表明,评估人类感觉强化剂的习惯可能需要参数评估。
