Language change has recently come to be seen as a complex dynamical system, along the lines of evolutionary biology and economics, as opposed to previous conceptions as a linear or cyclical system. We model the change of a particular phenomenon, vowel harmony, and look at the conditions under which the trajectory of change matches theoretical and empirical predictions. Our experimental work shows that there are certain conditions under which the desired trajectories do not occur, implying that absence of these conditions is necessary for accurate modeling of language change.
