“…Following Hasson et al's pioneering work on shared brain activity during naturalistic movie viewing (Hasson et al, 2004), researchers have made substantial progress in this field. On one hand, researchers have found that shared brain activity can reflect the multifaceted cognitive and emotional information processing properties of the human brain, such as shared understanding, empathy, mathematical ability (Cantlon and Li, 2013), cognitive development (Di and Biswal, 2022), education (Hu et al, 2019;Meshulam et al, 2021), interpersonal relationships (Parkinson et al, 2018), and even brain characteristics of mental illness (Hasson et al, 2009;Zhang et al, 2022;Jin et al, 2023).
