All dietary assessment methods engage the cognitive processes of respondents, requiring them to retrieve and report information from memory. I first discuss the distinction between daily and frequency methods of dietary assessment: from a psychological perspective, the essential distinction between these classes of methods is in the cues that are provided for retrieval of information rather than the length of the reference period or the specificity of the information to be retrieved. I then review selectively psychological research on aspects of cognition that are central to dietary reporting; chief among these are the nature of the representation of dietary information in memory and the fidelity of frequency judgments. I conclude by describing several potential areas for collaborative research between cognitive psychologists and nutritional epidemiologists. The ability of respondents to provide data must be considered in the design and selection of dietary assessment methods.
所有饮食评估方法都涉及受访者的认知过程，要求他们从记忆中检索并报告信息。我首先讨论饮食评估的日常方法和频率方法之间的区别：从心理学角度来看，这些方法类别之间的本质区别在于为信息检索提供的线索，而非参考期的长短或要检索信息的具体程度。然后，我将有选择地回顾关于饮食报告核心认知方面的心理学研究；其中主要包括饮食信息在记忆中的表征性质以及频率判断的准确性。最后，我将描述认知心理学家和营养流行病学家之间几个潜在的合作研究领域。在饮食评估方法的设计和选择中，必须考虑受访者提供数据的能力。
