“…Drawing on the GIF ( Spearman, 1928 ; Vernon, 1966 ) and GPF ( Musek, 2007 ; Wu, 2017 ; Wu et al, 2021 ), the current study put forward the concept of the general microexpression recognition ability (GMERA). We assumed that human microexpression recognition ability has a three-layer hierarchical structure: The highest layer is the GMERA, which may be derived from innate heredity and influenced by learning, and manifests the level of individual microexpression recognition ability (the current study); the second layer is the individual’s ability to recognize a type of microexpression under different expression backgrounds, for example, anger microexpression under sadness, fear, disgust, neutral, surprise, and happiness expression backgrounds ( Yin et al, 2020 ; Zhang et al, 2020b ); and the third layer is an individual’s ability to recognize a certain microexpression under a certain expression background, for example, anger microexpression under sadness expression background (please refer to Figure 1 , Zhang et al, 2017 ; Zhu et al, 2017 ; Yin et al, 2019 ).…”
