Perceptual competition between targets and distractors determines working memory access and produces intrusion errors in RSVP tasks

The two files reflect the full behavioural results from 4 experiments and main ERP results from one experiment. Each sheet reflects one experiment. The ERP recording information was as follows: A 500-Hz sampling rate with a 40 Hz low-pass filter was applied. Channels were referenced online to a left-earlobe electrode, and re-referenced offline to an average of both earlobes. Trials with eye blinks (exceeding ±60 µV at Fpz), horizontal eye movements (exceeding ±30 µV in the HEOG channels), and muscle movement artifacts (exceeding ±80 µV at all other channels) were removed as artifacts. In one analysis (one-item versus two-item trials) EEG was segmented into epochs from from 100 ms before to 800 ms after the onset of the target frame, relative to a 100 ms pre-stimulus baseline. In a second analysis (target 1st versus intrusion 1st) EEG was segmented into epochs from from 100 ms before to 500 ms after the onset of the target frame, relative to a 100 ms pre-stimulus baseline. The ERP results file average LRP difference wave (contralateral minus ipsilateral) at PO7 and PO8 electrodes. Averaged ERP waveforms were computed for trials with a target in the left or right RSVP stream, and LRPs triggered by the target frame were computed by comparing ERPs at electrodes PO7/PO8 contralateral and ipsilateral to the location of the target. Each column reflects the average results of a single participant, as a function of their response. In the first sheet: single item reports (target or distractor) vs. two item reports (target and distractor). In the second sheet: target first vs. intrusion first. For both cases, two additional sheets are included with an application of an additional 10 hz filter to segments.
