“…With too few observations it is impossible to model faster frequency oscillations, but with too many observations it is easy to mistake random noise for systematic fast oscillations. Second, if emotional oscillations are relevant to the research question, then classic approaches, such as repeated measures regression, temporal multilevel models, growth modeling, or sequential analyses are inadequate (Boker & Nesselroade, 2002; Butner et al, 2005; Hessler, Finan, & Amazeen, 2013). These methods can assess the general emotional tone of an interaction, trajectories of change across time, or within- and between-person concurrent associations (synchrony) and time-lagged associations (transmission), as well as moderators of these associations (Butler, 2011; Randall, Post, Reed, & Butler, 2013; Reed, Randall, Post, & Butler, 2013).…”
