Fig. 5: Relation between lexical parafoveal processing difference and individual reading speed.

The coherence-difference with respect to target lexical frequency during fixations on pre-target words were derived per participant (see Fig. 4b). The reading speed was quantified as the number of words read per second. Each dot represents a participant. A Spearman correlation demonstrated a significant relation (n = 26, two-sided). The solid gray line represents the linear regression fit with a 95% confidence interval (shaded area). Histograms of individual reading speed and pre-target coherence differences are shown on the top and to the right. Source data are provided as a Source Data file.
