“…Empirical evidence supports this claim. For instance, when neutral affect, defined as feeling neutral or indifferent, was directly measured, it was not highly correlated with positive and negative affective states (Gallegos & Gasper, 2017; Gasper & Danube, 2016; Gasper et al, 2018; Gasper & Hackenbracht, 2015), it formed a third factor in various factor and cluster analyses (Daly et al, 1983; Gasper & Danube, 2016; Gasper et al, 2018; Gasper & Hackenbracht, 2015; Sonneville, Schapp, & Elshout, 1981, as cited in Frijda, 1986; Storm & Storm, 1987), and it arose even when respondents reported the presence of positive and negative affect (Gasper & Danube, 2016). Neutral affect also exerted unique effects, in that it predicted making neutral judgments even when positive, negative, and ambivalent affects were taken into account (Gasper & Danube, 2016).…”
