Participants read sentences\nword-by-word (RSVP, 2 words per second) that contained indefinite articles\n(a/an) preceding either highly expected or unexpected nouns (based on cloze\nprobability), while EEG was recorded.\n\nNine laboratories in the UK collected data following a pre-registered\nreplication protocol (https://osf.io/eyzaq). The original study by DeLong et\nal. reported N400-like effects on the indefinite articles (larger negativity\nfor unexpected articles). Nieuwland et al. found reliable N400 effects on the\ntarget nouns but no statistically significant effect on the preceding\narticles, challenging strong prediction accounts.\n\nParticipants\n------------\n- 356 total participants (222 women / 134 men)\n- All right-handed, native English speakers\n- Age 18–35 years (mean 19.8)\n- Normal or corrected-to-normal vision\n- Free from known language or learning disorders\n- 89 reported a left-handed parent or sibling\n\nAfter applying the paper's quality threshold (<60/80 article or noun trials),\n334 subjects were retained in the statistical analyses.
