Figure 6.
ERPs elicited in the 300 ms interval after cue onset in the colour task, size task, and inverted colour tasks of Experiment 2 at posterior electrode sites PO7/8 contralateral (solid lines) and ipsilateral (dashed lines) to the visual hemifield where the colour singleton cue was presented. The bottom panel shows difference waves obtained by subtracting ipsilateral from contralateral ERPs in the colour task (solid black line), size task (dashed line), and inverted colour task (solid grey line).
