Figure 4.

Parametric modulation of percent signal changes (relative to voxel‐wise baseline) in Inferior prefrontal cortex as a function of participant group (Left set of bars = TD; Right set of bars = ASD), recognition judgement (Remembered triads purple; Known triads green) and the number of relational links in word triads (zero link, one link, and two link triads). The coronal section illustrates the voxel cluster that is sensitive to the inverse association between prefrontal signal changes and relational links in word triads across both groups of participants (P < 0.005; uncorrected with a minimum extent threshold of 10 contiguous voxels). As the barchart shows, however, this inverse relationship in TD participants was only observed for subsequently known but not remembered word triads, whereas in the ASD group the liniar decrease was robust irrespective of subsequent recognition judgement. Error bars represent 1 standard error.
