“…Iterative functions, such as those formalized by logistic equations, have proven particularly useful for modeling the dynamics of such phenomena as personality development (Nowak et al, 2005), language development ( van Geert, 1991), cognitive development ( van Geert, 1998), talent development (Den Hartigh et al, 2018Den Hartigh, van Dijk et al, 2016), and social development (Steenbeek & van Geert, 2008). Relatedly, differential equations and difference equations have made it possible to model many psychological phenomena in areas such as motor coordination (Haken et al, 1985), visual perception (Fajen & Warren, 2003;Warren, 2006), emotions (Hoeksma et al, 2007), interpersonal relationships (Gottman et al, 2002;Steele et al, 2013), and learning-teaching interaction (Merlone et al, 2019).…”
