Items that produced ambiguous results in an approach-based preference assessment were reassessed using a duration-based assessment. The reinforcing effects of three items on free-operant responding were subsequently tested. The results suggested that the duration-based assessment produced slightly more differentiated results and that predictions about reinforcer value, based on this assessment, were accurate.
在基于方法的偏好评估中产生模糊结果的项目,使用基于时长的评估进行重新评估。随后测试了三个项目对自由操作反应的强化效果。结果表明,基于时长的评估产生的区分结果略多一些,并且基于该评估对强化物价值的预测是准确的。
