How expressing one’s likes and dislikes affects enjoyment: a replication
复制了He等人2019年的研究，发现要求消费者做评价任务比非评价任务带来更多享受，但该效应在MTurk样本中仅间接成立，在未接触过实验范式的样本中则完全成立。
Abstract A recent article by He, Melumad, and Pham (Journal of Consumer Research 46(3):545–563, 2019) showed that consumers experienced greater enjoyment when they were asked to perform an evaluative task relative to a non-evaluative task. In this research, we intend to replicate this finding and to examine to what extent the strength of the effect is contingent on the sample employed. Using a sample from Amazon MTurk, study 1 replicates the indirect effect but not the total experimental effect. Study 2 draws on a sample that is unacquainted with the experimental paradigm and replicates the indirect as well as the total experimental effect. These findings suggest that the sampling population of MTurk may have become desensitized to the basic experimental paradigm.
