“…Previous studies on the impact of changes in the emotional valence of online reviews on consumer adoption intentions have mostly focused on the impact of the order of presentation of the emotional valence of a single review on consumer adoption intentions (Kim and Lee, 2015;Ruiz-Mafe et al, 2018;Bignea et al, 2022). Meanwhile, there has been a great deal of discussion surrounding the emergence of composite reviews, with particular attention paid to two main points: the impact of additional reviews on their own (Shen et al, 2015;Wang et al, 2020;Zhang et al, 2023) and the interaction between the initial review and the additional review (Zhou and Li, 2017;Wang et al, 2021;Chen et al, 2023). While few research have looked at how consumers' purchase intentions are affected by sequential changes in the emotional valence of composite reviews, and it is difficult to distinguish between the different effects of two changes in emotional valence due to the primacy and proximity effects (Chen et al, 2019).…”
