“…Some studies used test batteries such as Ekman and Friesen’s facial affect battery ( Airdrie et al, 2018 ; Rinke et al, 2017 ), the Child Affective Facial Expression Set ( Buongiorno et al, 2020 ), the facial emotion task from the Amsterdam Neuropsychological Tasks ( Waddington et al, 2018 ), the faces submodule of the Frankfurt Test and Training of Facial Affect Recognition second edition (FEFA2) ( Löytömäki et al, 2020 ), the National Institute of Mental Health Child Emotional Faces Picture Set ( Staff et al, 2022 ), and the Bochum Emotional Stimulus Set ( Thoma et al, 2020 ). Other studies used facial emotion pictures from databases such as The Karolinska Directed Emotional Faces database ( Helfer et al, 2021 ), the Cohn Kanade database ( Tehrani-Doost et al, 2017 ), and the Dartmouth database ( Wells et al, 2019 ). Finally, some authors employed morphing programs ( Greco et al, 2021 ; Jusyte et al, 2017 ; Maire et al, 2019 ; Staff et al, 2022 ) in FER tasks.…”
