Event-related brain potentials (ERPs) were recorded in two experiments to examine whether the time course of the orthographic priming effect depends on the emotional valence of the orthographic neighbor and on prime duration. Neutral target words (e.g., GICLER [squirt], TINTER [ring]) had only one higherfrequency orthographic neighbor. This orthographic neighbor was negative for half of the targets (e.g., gifler [slap]) and neutral for the other half (e.g., tenter [tempt]). Target words were presented in a primed lexical decision task, preceded either by their orthographic neighbor or by a non-alphabetic control prime. Two prime durations of 66 ms (Experiment 1) and 166 ms (Experiment 2) were used. In Experiment 1, results showed an orthographic priming effect on three ERP components (P150, N200 and N400) that was modulated by the negative emotional valence of orthographic neighbors. In Experiment 2, the same components were influenced by the orthographic priming effect, although their appearance latency was brought forward and their amplitude increased. However, the emotional valence of the neighbor no longer influenced the time course of the orthographic priming effect. The results are discussed in terms of early activation of the emotional content of the orthographic neighbor during word processing.
