Happiness Coding Definitions and Anchors from “Help and you shall be happy!”: A longitudinal analysis of preschool-aged children’s happiness after prosocial action

Note. The coding scheme was inspired by the work conducted by Aknin et al. (2012) and Cole and colleagues (2007). The target emotion of happiness includes behaviours characterised as joyful, excited, enthused, delighted, gleeful, and pleasantly surprised. Vocal cues (i.e., light, high pitch, laughing, giggling) as well as facial (smiling, corners of mouth turn up, cheek area rounds up, crinkling around the eyes) and posture/gesture (warm-glow, raise up arms, squeeze shoulders to ears, jumping) cues where incorporated in the coding scheme. C = Child; E1 = Main Experimenter.
