Abstract
A moment of insight is the experience of sudden comprehension when, for example, solving a puzzle. Insight in the brain is often studied using functional magnetic resonance imaging (fMRI), which has the disadvantage of not recording a continuous data stream. Electroencephalography (EEG), which is recorded continuously, could be a useful alternative to fMRI when looking at insight in the brain. EEG data from twenty-five participants was used to analyse whether there are patterns in electrical activity in the brain when one experiences insight. Possibly, this can be useful to investigate the use of EEG data for studying insight in the brain. Participants were experienced chess players who were asked to solve 100 chess puzzles. On EEG data, an Event-Related Potential (ERP) analysis was applied, in which data was averaged over all trials and all participants. Results confirmed an N200 component and a P300 component found in previous studies investigating ERPs and insight. However, no response-locked ERP components were found preceding preparedness to answer, and no previously reported stimulus-locked ERP components could be attributed to insight prior to a response.
