For each trial, subjects were given a target logogriph followed by three types of base logogriphs: surface similarity logogriphs (SUSL, the base logogriph and target logogriph share some same words), structural similarity logogriphs (STSL, the base and target logogriphs do not have any words in common), and baseline logogriphs (BSL, the base and target logogriphs are all simple character-generation tasks). The results demonstrated a more negative event-related potential deflection during STSL than during SUSL in both the 300-500 and 1,100-1,300ms time windows, most likely reflecting the breaking of mental sets during insight-like problem solving. Moreover, SUSL and STSL demonstrated greater positivity than BSL in a time window between 900 and 1,700ms, possibly reflecting processes such as forming novel associations.
