cross-lagged, coupled oscillatory model of women’s aggression. A model of aggression with only trials where the aggressor is a woman, allowing us to examine how women behave depending on whether the target is a man or another woman. The model can be read and interpreted as described in Fig. a3. In addition, all predictor paths (and the intercept) include two estimates. Values shown in grey represent women-women pairs, acting as the reference pair absorbed into the intercept. Values in black represent women-man pairs, representing the difference between woman-woman and woman-man pairs (i.e., how the predictors change, rather than an absolute value of the estimate for woman-man pairs). For example, when all predictors are zero and we have a woman-woman pair, the predicted blast level is 1.28. The predicted blast for a woman-man pair (all else being zero) is the base estimate (1.28) plus the difference for woman-man pairs (1.55), resulting in a blast of 2.83. The same addition rules hold for estimates of the influence of predictor variables. For example, a one unit increase in aggressor velocity predicts a 1.03 unit increase in blast level for woman-woman pairs (bringing the estimated blast to 2.31). For woman-man pairs, there is an additional predicted increase of 0.03, such that the estimated blast is 3.89 (i.e., 1.28 + 1.55 + 1.03 + 0.03). Significant predictors are indicated using ** for p < 0.01; *** for p < 0.001 and the model explains ~ 75% of variance in the aggressor’s next blast level selection.
