Figure 4. The outcome of the mediation/moderation models predicting trial-by-trial performance.

Figure 4.

Top Row: The relationships between DLPFC activity and reaction time. Bottom Row: The relationships between amygdala activity and reaction time. Left hand column: The relationships for congruent trials. Right hand column: The relationships for incongruent trials. Trial-by-trial Fits for word and face classifiers, respectively serve as potential mediators in the model. Significant effects that pass the bootstrapping threshold are shown by solid arrows. Those that do not pass the bootstrapping threshold are shown by dotted arrows. Brain regions involved in cognitive control and processing task-relevant information are shown in blue. Brain regions involved in emotional salience and processing task-irrelevant information in orange. The effects of individual differences moderators are shown in green and are depicted by arrows with a double line shaft. Notable findings are that 1) increased DLPFC activation in both incongruent and congruent trials was associated with a reduce fit for the face classifier, consistent with top-down modulation to decrease the influence of the task-irrelevant face, 2) both DLPFC and AMG activation influence RT on incongruent but not congruent trials, with the direct effect only significant for the AMG model, and 3) that individual differences moderates the effect of how much processing of the task-irrelevant face influences RT, being increased for individuals with high negative affect and decreased for individuals with high executive control.
