Goals of study: Event-related functional magnetic resonance imaging was used to explore the interactions of emotion and (within-task) cognitive load using an affective number Stroop task. Method: In this study, two congruent, or alternatively incongruent, numerical displays were bracketed by negative, neutral, or positive IAPS pictures (e.g., four 5s -> picture of snake -> five 4s -> picture of snake). The participants’ task was to compare the numerosities in the two numerical displays and indicate whether the first or the second numerical display represented the greater numerosity. MRI scanning was performed on a 1.5 Tesla MRI scanner. Results: We found a significant emotion by task-load interaction with emotional content (positive as well as negative) modulating the neural response to the incongruent, but not the easier congruent condition. In addition, brain responses to emotional stimuli were modulated by task load. Conclusion: These results indicate that both positive and negative information can interfere with cognitive processing. However, the extent of this interference is modulated by cognitive task load. In addition, task load modulates cognitive processing. These results are discussed with reference to a computational model of the interaction of affect and number processing/cognition.
