资源简介:
The two files reflect the full behavioural results from 3 experiments and main ERP results from 2 experiments. Each sheet reflects one experiment. To reproduce the behavioural data presented in the relevant paper, exclude trials from practice blocks (practice = 1) and trials with incorrect duration (Excluded(durations) = 1). 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 ±40 µV in the HEOG channels), and muscle movement artifacts (exceeding ±80 µV at all other channels) were removed as artifacts. 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 the relevant condition and time window. PTD = Post-target distractor PreTD = Pre-target distractor
