The number of expected targets modulates access to working memory: a new unified account of lag-1 sparing and distractor intrusions - data from 3 experiments

The two files reflect the full behavioural results from 3 experiments and main ERP results from one experiment. Each sheet reflects one experiment.<br>The ERP recording information was as follows:<br>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 ±40 µV in the HEOG channels), and muscle movement artifacts (exceeding ±80 µV at all other channels) were removed as artifacts. In one analysis (Expect 1 versus Expect 2 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.<br>Each column reflects the average results of a single participant, as a function of the relevant condition. In the first sheet: Expect 1 vs. Expect 2. In the second sheet: response on the first response (T1 first vs. Post-T1 first) and number of targets (1 target vs. 2 targets). For both cases, two additional sheets are included with an application of an additional 10 hz low-pass filter to segments, for purposes of a latency analysis.
