Fig. 1From: The regulatory properties of anger under different goal orientations: the effects of normative and outcome goalsDescription of the cusp model within the context of the present study. When asymmetry and bifurcation levels are low, the relationship between the focal variables is expected to be linear (Pattern A). When levels in the bifurcation variable increase beyond a specific critical threshold, Pattern B is expected to be associated with non-linearity. HRPM heart rate per minuteBack to article page
