接缝效应是小组调查的产物，在小组调查中，每隔几个月（例如）对受访者进行一次采访，并要求他们提供中间每个月的数据。这种效应的定义是，在一个参考期内（即在一次访谈中）相邻月份之间的反应变化较小，相对于在不同参考期内（即在不同访谈中）相邻月份之间的变化较大。在本研究中，我们使用实验方法来检验关于美元金额的定量问题的接缝效应。这些研究产生了强大的接缝效应，在参考期内，伴随着正确数量的遗忘和持续的反应（月份之间没有变化）。研究结果还显示，当同一话题的问题出现在面试的不同部分时，“接缝效应”会减弱。在某些情况下，依赖访谈（向受访者提供他们先前的答案）也减少了接缝效应的大小。然而，这两种操作都没有提高反应的总体准确性。依赖反馈可能会鼓励受访者在接缝处做出不那么剧烈的改变。但是，由于早期的答案本身可能包含错误，依赖性访谈也可能使同样的错误回答从一个参考时期延续到下一个参考时期。
The seam effect is an artifact of panel surveys in which respondents are interviewed every few months (for example) and asked for data about each of the intervening months. The effect is defined by small changes in responses between adjacent months within a reference period (i.e., within an interview) relative to large changes between adjacent months across reference periods (i.e., across interviews). In the present studies, we used an experimental method to examine the seam effect for quantitative questions about dollar amounts. The studies produced robust seam effects, accompanied by forgetting of correct amounts and constant responding (no change between months) within the reference periods. The results also showed decreases in the seam effect when questions about the same topic appeared in different parts of the interview. In some conditions, dependent interviewing (providing respondents with their earlier answers) also reduced the size of the seam effect. Neither manipulation, however, improved the overall accuracy of responses. Dependent feedback may encourage respondents to make less drastic changes at the seam. But since the earlier answers may themselves contain error, dependent interviewing can also perpetuate the same incorrect response from one reference period to the next.
