Robinson and colleagues (2018) make important first steps in highlighting the shortcomings of laboratory studies of human eating behaviour, and providing some general suggestions to increase methodological and reporting quality. In this commentary, we present additional important theoretical considerations and practical suggestions. First, we discuss the role of situational cues in eating behaviour and highlight the implications for designing ecologically valid laboratory experiments. Next, we discuss food intake in laboratory settings in the context of the distinction between implicit and explicit measures used widely in social psychology, and provide practical recommendations to keep intake a relatively implicit measure. Finally, we recognise that designing optimal experiments requires significant resources so we present a practical procedure to recruit the smallest informative sample via Bayesian sequential hypothesis testing.
罗宾逊等人（2018 年）在强调实验室研究人类进食行为的不足之处方面迈出了重要的第一步，并提供了一些提高方法和报告质量的一般性建议。在这篇评论中，我们提出了其他一些重要的理论考虑和实际建议。首先，我们讨论了情境线索在进食行为中的作用，并强调了这对设计具有生态效度的实验室实验的影响。接下来，我们在社会心理学中广泛使用的内隐和外显测量的区别的背景下讨论了实验室环境中的食物摄入量，并提供了保持摄入量相对内隐测量的实用建议。最后，我们认识到设计最佳实验需要大量资源，因此我们提出了一种通过贝叶斯序贯假设检验来招募最小信息量样本的实用程序。
