Prior to target presentation, the directional word cues 'left' or 'right' were presented auditorily or visually from the centre of the display at cue-target stimulus onset asynchronies (SOAs) of 200, 400, or 600 ms.
Prior to target presentation, neurons in both LPFCv and LPFCd encoded the choice outcome in goods space.
Similarly, transient activity prior to target presentation can prompt an increase in ITPC when it is time-locked to temporally predictable stimuli.
It is a well-established neural correlate of attentional allocation34,35 derived from difference waves of the electrodes from the hemisphere ipsilateral and contralateral to target presentation, using the PO7 and PO8 occipito-parietal electrodes (Luck, 2012, offers an extensive review in support of this difference wave analysis approach to the N2pc36).
For statistical analyses, only the vigilance stages that occurred 1 sec prior to target presentation were evaluated.
VIGALL classifies 1-sec-segments of the EEG data prior to target presentation separately for each trial and subject.
Study-relevant EEG-segments were cut out including two 1-sec-segements before and after the relevant segments prior to target presentation.
Targeted presentations will provide a forum for discussing the research process, data analysis, and interpretation of results.
One possible explanation for different sensitivity to errors of commission versus omission is the low target presentation rate in the NES2 CPT; that is, the target is presented infrequently.
In the gap condition, the central fixation point was presented for 800 ms and extinguished 200 ms before peripheral target presentation.
Thus, within a standard distractor-present redundant-target task, the RT gains produced by redundant target presentation were smaller than predicted by statistical facilitation in a UCIP model.
