“…N2pc onset latencies were measured on the basis of difference waveforms obtained by subtracting ipsilateral from contralateral ERPs at PO7/8. Onset latencies were determined with a jackknife-based procedure (Miller, Patterson, & Ulrich, 1998;Ulrich & Miller, 2001). Sixteen grand-average difference waves were computed for each experimental condition (horizontal target in the first or second display in single-or dualtarget trials), each excluding one different participant from the original sample.…”

“…This absolute threshold was defined as 50% of the peak amplitude of the smallest N2pc component in any of the trial conditions (the N2pc for H1 dual-target trials; see Figure 2). F-and t-values of the statistical comparisons were corrected according to the formulas described by Ulrich and Miller (2001) and Miller et al (1998), respectively. The corrected values are indicated with the labels 'F c ' and 't c '.…”

“…2a. We used the time when the waveform reached 50 % of the peak amplitude as a measure of the onset of stimulus-locked LRPs (Miller et al 1998). The mean amplitude was measured in the time window of 150-250 ms for the positive-going Gratton-dip and 200-300 ms (congruent condition) and 350-450 ms (incongruent condition) for the following negative-going deflections.…”

The Simon effect indicates that the reaction time (RT) is shorter when the stimulus and response locations are congruent than when they are not. This study used a priming-target paradigm to explore the emotion-priming Simon effect with event-related potential techniques. The technique of residue iteration decomposition was employed to analyze the lateralized readiness potential (LRP) component, which contributed to disentangling the overlap between LRP and N2 central contralateral in the Simon task with horizontal stimulus-response arrangements. The behavioral result revealed significant Simon effect in RT. In the neural process, the Simon effect was reflected by both the stimulus-locked LRP (S-LRP) and the response-locked LRP (R-LRP), with the incongruent condition showing longer onset latency, larger Gratton-dip, and smaller negative-going deflection of S-LRP and smaller negative-going deflection of R-LRP. These findings suggest that the interference of irrelevant location information is located at the perceptual-encoding (indicated by S-LRP) and response-execution stages (indicated by R-LRP), providing evidence for both the perceptual-interference and response-interference accounts. However, the further linear regression result signaled that the Simon effect might be more closely related to the response-execution stage than the perceptual-encoding stage. In addition, the influence of emotion on the Simon effect was salient only in the incongruent condition, showing longer onset latency of S-LRP and larger Gratton-dip of R-LRP in the negative emotion-priming condition than in the neutral emotion-priming condition, which revealed that the emotional interference effect arose from the stages of perceptual encoding and early response execution only when the locations of a stimulus and the corresponding response were incongruent.

“…A jackknife-based scoring method with a relative criterion of 50% of the peak LRP amplitude was chosen for measuring S-LRP and LRP-R onset latencies, respectively (cf., Miller et al 1998). This scoring technique has been developed to increase the low signal-to-noise ratio commonly observed with LRP data before onset detection.…”

“…1. As the applied jackknife procedure strongly reduces SEM, obtained t values and SEM were corrected according to a procedure described by Miller et al (1998). Pergolide markedly decreased S-LRP latencies compared to placebo [t(11)=6.5, p<0.001]; S-LRP latencies were 289 and 332 ms under pergolide and placebo, respectively.…”

The results indicate that dopaminergic neurotransmission effectively modulates early perceptual and cognitive stages of information processing as suggested by neural network models of the functional role of prefrontal DA. The lack of an effect on aspects of motor processing may be due to a higher capacity of the nigrostriatal compared to the mesocortical DA system to compensate pharmacologically induced changes in dopaminergic activity.
