Table 1.
Stimulus types.
Figure 1.
RTs (ms; a) and error rates (% incorrect responses; b) for the different stimulus categories (see Table 1 for explanation of abbreviations). Top panel depicts trial level congruency effects, the middle panel depicts sequential trial effects for the different congruency conditions and in the lower panel results of the different feature repetition conditions are shown. Percentage errors are expressed relative to the number of trials within the specific stimulus category.
Figure 2.
ERPs for different congruency conditions.
Average ERPs recorded from Fz, Cz and Pz, superimposed for the congruent (solid lines) and incongruent condition (dotted lines). ERPs are averaged over time on task conditions.
Figure 3.
ERPs for different time on task intervals.
Average ERPs recorded from Fz, Cz and Pz, superimposed for the four time on task intervals. ERPs are averaged over sequence conditions.
Figure 4.
ERPs for different repetition conditions.
Average ERPs recorded from Cz and Pz, for the different repetition conditions in each sequence condition (CC: left upper panel; CI: left lower panel; IC: right upper panel; II: right lower panel).
Figure 5.
RTs (ms) superimposed for the different sequence conditions in the first (0–30 min) and fourth time on task interval (90–120 ms; see Table 1 for explanation of abbreviations).
Figure 6.
ERPs for the CI (solid lines) and II (dotted lines) colour-repeat sequence conditions.
Average ERPs recorded at Fz and Cz.
