We evaluated the extent to which access duration during stimulus preference assessments affects preschool-age children's preferences for leisure items. Results demonstrated that rankings for highly preferred items remained similar across both short- and long-access durations; however, overall preference hierarchies remained more similar across administrations of long-access-duration assessments than short-access-duration assessments.
我们评估了在刺激偏好评估期间的接触时长对学前儿童对休闲物品的偏好的影响程度。结果表明，高度偏好项目的排名在短时间和长时间接触时长下相似；然而，长时间接触时长评估的总体偏好等级比短时间接触时长评估更相似。
