“…Thereby, greater right relative to left frontal activity has been linked to withdrawal‐oriented emotions, to an avoidance motivation, and to the experience of negative affect (e.g., Davidson, Ekman, Saron, Senulis, & Friesen, ; Fox, ; Fox, Henderson, Rubin, Calkins, & Schmidt, ; Harmon‐Jones, Gable, & Peterson, ; Jones & Fox, ; Saby & Marshall, ; Shankman et al, , ; Sutton & Davidson, ). Furthermore, greater relative left frontal activity has been associated with approach‐oriented emotions, to an approach motivation, and the experience of positive affect (e.g., Davidson & Fox, ; Fox, ; Fox et al, ; Harmon‐Jones et al, ; Licata, Paulus, Kühn‐Popp, Meinhardt, & Sodian, ; Paulus, Kühn‐Popp, Licata, Sodian, & Meinhardt, ; Pizzagalli, Sherwood, Henriques, & Davidson, ; Shankman et al, , ; Sutton & Davidson, ; Tomarken & Keener, ). For example, video clips that evoke fear or disgust resulted in greater relative right frontal brain activity (Davidson et al, ; Jones & Fox, ), while 10‐month‐old infants displayed increased left frontal activation after watching film clips of a woman with a happy facial expression as compared with a sad expression (Davidson & Fox, ).…”
