Effects of regulation on heart rate changes as compared to trial baseline level during negative (a, b, and c) and positive (d, e, and f) trials. Are considered the interaction between Time and Suppression (a and d), the interaction between Time and Situation selection (b and e), and the contrast between the Unregulated condition and the use of either one or the other strategy and to the Double regulation condition, in the period spanning between 3 s (c) or 4 s (e) and 8 s after image onset. The error bars are SEM. Ns = not significant, *p < .05, * in c and f represent significance of contrasts with each of the three other conditions
