The interaction was further analysed with two-tailed paired t tests comparing congruent and incongruent trials separately for each SOA, showing that a congruency effect did not emerge at the two shorter SOAs ( p s > 0.717), as well as at the longest SOA ( p = 0.075), although the means showed an increasing trend in the magnitude of the attention-orienting response (see also Fig. 2 A).
