Interpreting and predicting direction of preference in infant research has been a thorny issue for decades. Several factors have been proposed to account for familiarity versus novelty preferences, including age, length of exposure, and task complexity. The current study explores an additional dimension: experience with the experimental paradigm. We reanalyzed the data from 4 experiments on artificial grammar learning in 12-month-old infants run using the head-turn preference procedure (HPP). Participants in these studies varied substantially in their number of laboratory visits. Results show that the number of HPP studies is related to direction of preference: Infants with limited experience with the HPP setting were more likely to show familiarity preferences than infants who had amassed more experience with this paradigm. This evidence has important implications for the interpretation of experimental results: Experience with a given method or, more broadly, with the laboratory environment may affect infants' patterns of preferences.
几十年来，解读和预测婴儿研究中的偏好方向一直是一个棘手的问题。已经提出了几个因素来解释熟悉度与新颖性偏好，包括年龄、暴露时间和任务复杂性。本研究探讨了另一个维度：对实验范式的经验。我们重新分析了使用头转偏好程序（HPP）进行的 4 项 12 个月大婴儿人工语法学习实验的数据。这些研究中的参与者在实验室访问次数上有很大差异。结果表明，HPP 研究的数量与偏好方向有关：与那些积累了更多该范式经验的婴儿相比，对 HPP 环境经验有限的婴儿更有可能表现出熟悉度偏好。这一证据对实验结果的解释具有重要意义：对给定方法的经验，或者更广泛地说，对实验室环境的经验，可能会影响婴儿的偏好模式。
