Fig. 6: Predictors of cognitive performance across tasks and time points.

a, Ranking of predictors based on the projection predictive inference model for the five tasks in the two phases. The order (left to right) is based on average rank across phases. Solid points indicate predictors selected as relevant. The colour of the points shows the category of the predictor. Line type denotes the phase. b, Posterior model estimates for group for tasks for which it was selected as relevant. c, Posterior model estimates for the remaining selected predictors for each task based on data from n = 43 participants. Points show means with 95% CrI. Colour denotes phase. For categorical predictors, the estimate gives the difference compared to the reference level (Bonobo for group, no observer for observer, hand-reared for rearing, male for sex).
