Figure 3. Interactions of linguistic predictors.

Figure 3

Predicted values for significant (t > 2) interactions of linguistic predictors. In all figures, grey error bars indicate 99% confidence intervals. (a) Cohort size significant interacted with lexicality. There is a strong decrease in the predicted neural response to words as cohort size shrinks. This effect is relatively attenuated for pseudowords. (b) Cohort size and average cohort frequency also interacted. The effect of decreasing cohort size on the neural response was strongest in the most frequent cohorts. (c) Cohort size and summed cohort frequency had a different interaction pattern compared to average cohort frequency. For the highest and mid-range summed frequencies, the predicted response decreased as cohort size decreased. This effect was reversed for cohorts with the smallest summed cohort frequencies. (d) Average and summed cohort frequency interacted, suggesting a dissociation between these metrics. Responses in high and mid summed cohorts increased as average cohort frequency decreased. This effect was reversed for low summed cohorts.
