Difference topographies and ERP waveforms of the effects of prime valence in the response-locked analysis at clustered sensors in Experiment 1. (a) Topographic map of the significant effects of positive valence (ERPs to positive primes minus ERPs to neutral primes). (b) Grand-averaged ERP waveforms to responses preceded by neutral, positive and negative emojis.
