“…In each model, we used temperature, humidity, and contrast-coding for the two emotion conditions (awe-contrast: awe = 2/3, amusement = − 1/3, neutral = − 1/3; amusement-contrast: awe = − 1/3, amusement = 2/3, neutral = − 1/3) as fixed effects with one random intercept for participants 9 . Regarding the physiological measurements, we examined whether there were effects of other emotions, habituation, or demographic heterogeneity because some previous studies have suggested that these factors may moderate the effects of awe 38 – 41 . We considered three models in addition to the simple models: control models, which controlled for the main effects of emotions other than awe that were elicited from the video (i.e., amusement and fear as general positive and negative emotions, respectively); order models, which included the interaction effects between the contrasts and the order in which the videos were presented within each emotion condition (first = − 1/2, second = 1/2); and demographic models with the interaction effects between awe-contrast and age and gender (the values of age were centered).…”
