Figure 2. ERPs for the first presentation of targets.

Figure 2

ERPs are shown for targets presented for the first time as well as for the words immediately preceding these targets. A ERPs for targets preceded by unrelated words and for the unrelated words. B ERPs for targets preceded by primes and for the primes. C Overlay of all four conditions at electrode Cz. Primed targets (P. Targets) are those that followed primes. Unprimed targets (U. Targets) are those that followed unrelated words. ERPs were matched except for primed targets, which showed positive N400 shifts. D The topography of ERP difference between primed targets and their primes is shown for the N400 interval, with difference amplitude values indicated by coloration.
