Metrics for modelling conflict behaviour. When accounting for an aggressor’s next blast level, we are interested in their previous behaviour, as well as the target’s previous behaviour. We introduce three variables to model previous behaviour in each member of a pair: (A) Level refers to aggression (i.e., blast selection) in the most recent round; (B) Velocity is the change in aggression (i.e., level) across the two most recent rounds; and (C) Acceleration is the change in velocity across the three most recent rounds. We examined each pairs behaviour, over all successive rounds, using a Cross-Lagged Coupled Linear Oscillator Model to produce a stationary account that shows the relationship between current behaviour and each individual’s previous aggression (i.e., level), trajectory (i.e., velocity), and volitivity (i.e., acceleration).
