then, N400 measures revealed ongoing semantic processing even when such analysis was orthogonal to task performance and not evidenced in overt behaviors (e.g., Kuper & Heil 2009). Still, in all these types of studies, participants directed their attention to the stimuli (if not the semantic level of analysis), and that seemed to be important for N400 elicitation. This possibility was examined in a number of studies crossing priming with selective attention (reviewed in Deacon & Shelley-Tremblay 2000).
