- W755237801 abstract "Two analyses were carried out. The first grand averaged ERP analysis asked whether word-in-context differed from word-before-context. ERPs showed negativity (170-450 ms, central-posterior) more negative for word-in-context than for word-before-context. The onset of the negativity was 170 ms, suggesting some context effect at the initial stage of semantic construction. The second EEG classification analysis asked that, within word-in-context, whether EEG patterns differed between affective (positive/negative) context and ontological (animal/human) context. Signals were segmented in 100-ms interval post word onset. Using single-trial multivariate analysis, Support Vector Machine (Vapnik, 2000) classifier was trained to do the binary classification. In word-before-context condition, percentage of correctly classified trials stayed at chance for all intervals (50%), as expected. Remarkably, classification accuracy in word-in-context condition was above the chance across 30 participants in 200-300 ms (54%, p=0.0006, against chance-level). This suggests that semantic representations for the same word in the same brain already differed between “word-in-affectivecontext” and “word-in-ontological-context”, initially. Context effects are detectable at the earliest semantic stage during word processing, evidenced by both grand-averaged ERPs and single-trial EEG. These findings support a view in which default/invariant word meanings are not accessed from a mental lexicon and later modified by context. Rather, from their inception semantic representations are codetermined by word and its context." @default.
