MEG sensor data. The average evoked response to the critical noun is displayed for each condition: A, two-word composition; B, one-word composition; C, two-word list; D, one-word list. Canonical visual response peaks and field patterns (M100 and M170) (Tarkiainen et al., 1999; Pylkkänen and Marantz, 2003) are visible at ∼100 and 150 ms in all four conditions. Subsequent M250 and M350 peaks and field patterns (Pylkkänen et al., 2002; Pylkkänen and Marantz, 2003) are also present across all four conditions. A typical anterior midline field pattern (Pylkkänen and McElree, 2007) can be seen accompanying a sustained increase in activity from 300 to 500 ms within the two-word composition condition. This field pattern is absent from the other three conditions.
