Ego-depletion-dependent performance decreases over the course of time.
P0 and P1: Logits of the changing item-solving probabilities over the course of testing (Item Position 1–45) for students assigned to the ego-depletion group in reference to the no depletion group (solid line). The 95% confidence intervals (dashed lines) indicate that the probability of solving item 28 and any following item was significantly lower for the ego-depletion group. P1a and P1b: Decomposed effects of P1, separated for high trait self-control (TSC) students (P1a) and low-trait self-control students (P1b).
