Figure 1

(a) WM task diagram. (b) Stop-signal task diagram. (c) WM task, behavioural data from the behavioural experiment. Left panel: WM accuracy by trial type. WM accuracy is reduced following surprising compared with standard tones (paired samples t-test, N=20, t(19)=3.5, P=0.0026 , d=0.78). Right panel: Bayesian surprise values of surprising trials split by WM accuracy. Surprise is increased for tones that interrupted WM (paired samples t-test, N=20, t(19)=2.14, P=0.045, d=0.77). Error bars denote s.e.m. (d) WM task, behavioural data from the scalp-EEG experiment, description as in c (WM accuracy: paired samples t-test, N=20, t(19)=2.3, P=0.033 , d=0.49; increased surprise for failed WM: paired samples t-test, N=20, t(19)=2.6, P=0.019, d=0.91).
