Fig. 2: Results from the five cognitive tasks across time points.

Black crosses show mean performance at each time point across all individuals in the sample at that time point (with 95% confidence interval). The sample size varied between time points and can be found in Supplementary Fig. 1. Coloured dots show mean performance by group. Light dots show individual means per time point. Dashed lines show chance level whenever applicable. The vertical black line marks the transition between phases 1 and 2.
