[…] 19 to 32 channel EEG was recorded at 250 Hz, band passed 0.016 to 100 Hz, and re-referenced off-line to linked mastoids. The pre-processing of the EEG data was performed using EEGLAB (). Fieldtrip () EEG epochs were locked to the onset of the visual target words and manually inspected for non-physiological artefacts. Independent component analysis was then applied to remove eye movement artefacts (). Our classifications of frequency bands into alpha (9–11 Hz), theta (3–5 Hz) and beta (15–20 Hz) were based on prior literature (, , , ) and word-induced changes in power irrespective of the condition or participant group.
