Sources for the components resembling the N400 and P600 responses. SourceĪnalysis of these independent components implicated the right frontal eye field as the cortical source for the frontal negativity and the middle temporal and parietal regions as cortical Negativity concealed s more typical and separate N400 response, which was similarlyĭelayed in the anomalous word neighbour condition, as was the P600 response. Signals not only confirmed the delay of the P600 response but also revealed that the frontal We performed group-level decomposition on the data with ICA (independent component analysis) and analysed the timeĬourse and source structure of the decomposed data. Was delayed in the anomalous word neighbour condition.

From the P600 response of the scalp waveform, we observed that the P600 We thus show that the brain successfully usesĬontext to separate anomalous words from plausible words on a single letter level duringįree reading. Response elicited by the plausible condition. This frontal negativity was larger in both anomalous conditions than in the In the fixation-related potential of the unrelated anomalous words and in the anomalous Similarly, we observed frontal negativity That the anomalous word neighbours of plausible words cause similar first-fixation and gazeĭuration reactions, as do other anomalous words. With an anomalous word neighbour of a plausible word. We also examined whether the representation invoked by the sentence contextĮxtends to the orthographic representation level by replacing the final words of the sentence The detection of such anomalies is typically reflected in the N400 event-related

In this study, we investigated the effects of context-related semantic anomalies on the fixation-related brain potentials of 12–13-year-old Finnish children in grade 6 during sentence
