Data for: Asymmetry of affect in verbal irony understanding: What about the N400 and P600 components?

We investigated the neurocognitive processes behind the asymmetry of affect observed in irony understanding, where ironic criticism is more easily understood than ironic praise. We recorded the ERPs of participants while they listened to positive (e.g., “These children are always smiling”) or negative (e.g., “His son is very unfortunate”) remarks pronounced with a sincere or ironic prosody. Participants had to decide whether or not the speaker was sincere. Two ERP components were of interest: the N400 and the P600
