Figure 4.

Interaction between the left temporal (T3) difference measure of word processing and the number of word stimuli reportedly understood by the participant predicting concurrent receptive vocabulary. Word processing values reflect the word–nonword average difference score in microvolts from 200 to 500 ms after stimulus onset. Microvolt values on the x-axis correspond to the minimum, maximum, mean, and 1 SD above and below the mean, in sequential order. Receptive vocabulary is measured by the raw scores from the MacArthur–Bates Communicative Development Inventories (MCDI; Fenson et al., 2007). The gray shaded region reflects the region of significance, which ranges from 4.05 (i.e., 5) to 10 word stimuli understood.
