a Temporo-spatial evolution of the normalized CNV in trials with the long foreperiod across cueing conditions. In this analysis, we evaluated the explicit temporal orienting given (1) the averaged amplitude of the CNV within the 400-1000 ms time interval and (2) the slope of the CNV representing the amplitude difference between 1000 ms and 400 ms. In trials with the neutral (b) and temporal (c) cues, the amplitude of the CNV was not significantly reduced in VGPs (N = 22) relative to NVGPs (N = 23). Gray areas represent the time intervals used to calculate the slope of the CNV. d Independently of the group, the amplitude of the CNV was reduced in the temporal cue condition relative to the neutral cue condition. e All CNV slopes were negative, except in VGPs in the temporal cue condition. f Correlation analysis indicated that participants benefiting from the temporal cue in trials with the long FP exhibited a more negative CNV slope in the temporal rather than in the neutral cue condition. Colored shaded areas represent ±one SEM. Error bars represent ±one confidence interval of the mean. *p < 0.5, **p < 0.01.
