(A) Congruency effects in the P3b latency and in reaction time in subjects accepted for EEG analysis. Conditions are represented on the X axis: Ne: neutral. Co: Congruent. IC: Incongruent. (B) Facilitation and interference effects on the reaction time (RT) and on the latency of the P3b ERP component in grade 3 (G3), grade 5 (G5), and in adults (Ad). The RT of all 46 subjects and of the 30 of subjects accepted for EEG analysis is shown separately. Facilitation and interference values were computed as Congruent minus Neutral, and Incongruent minus Neutral values. The deviation of the difference values from zero was tested by two-tailed one-sample t-tests against zero. Results of these tests are represented by "*", "+" and "#" signs (see legend). Double-headed arrows denote the cases when interference effects on the latency of the P3b and the on RT were significantly different (see text for details). The insert shows the difference between the RT and P3b latency in milliseconds (with standard errors). X axis of the insert: "N,Co": the average of the neutral and congruent conditions. "N,IC": the average of the neutral and incongruent conditions.
