The target paper proposes six solutions to increase the reliability of infant research, with expected benefits for robustness and replicability. In this commentary, I highlight that signal detection theory can help the framing of reliability issues, and that reliability does not address the core problem of internal validity. The relative merits and challenges of the six solutions are reviewed. A seventh solution is proposed to address the validity issue that remained overlooked. The lack of general theories about the infant mind is probably the biggest obstacle to progress in the field. Instead of whether questions, asking how questions should be at the forefront of future research.

第七个解决方案：对拜尔斯-海因莱因、伯格曼和萨瓦莱的评论（2022）

目标论文提出了六种解决方案来提高婴儿研究的可靠性，并有望带来稳健性和可复制性的好处。在这篇评论中，我强调信号检测理论可以帮助构建可靠性问题，而可靠性并没有解决内部有效性的核心问题。回顾了六种解决方案的相对优点和挑战。提出了第七个解决方案来解决仍然被忽视的有效性问题。缺乏关于婴儿心智的一般理论可能是该领域取得进展的最大障碍。与其问是否问题，不如问问题应该如何成为未来研究的前沿。
