Why might negative mood help or hinder inhibitory performance? An exploration of thinking styles using a Navon induction.

Theories of affective influences on cognition posit that negative mood may increase cognitive load, causing a decrement in task performance (Seibert & Ellis, [1991]. Irrelevant thoughts, emotional mood states, and cognitive task performance. , (5), 507-513), or cause a shift to more analytic thinking, which benefits tasks requiring attention to detail (Schwarz & Clore, [1983]. Mood, misattribution, and judgments of well-being: Informative and directive functions of affective states. , (3), 513-523). We previously reported that individuals who are higher in the trait of emotional reactivity performed better on an inhibitory task with increasing negative mood whereas low-reactive individuals showed the converse pattern (Gabel & McAuley, [2018]. Does mood help or hinder executive functions? Reactivity may be the key. , , 94-99; [2020]. React to act: Negative mood, response inhibition, and the moderating role of emotional reactivity. , (6), 862-869). Because high-reactive individuals are more accustomed to negative affect (Nock et al., [2008]. The emotion reactivity scale: Development, evaluation, and relation to self-injurious thoughts and behaviors. , (2), 107-116), we speculated that negative mood engendered analytic thinking but without a task-incongruent increase in cognitive load - thereby facilitating performance. Here, we induced a heuristic or analytic approach to information processing prior to performance of an inhibitory task and expected different results pending the thinking style induced. In the heuristic condition, increasing negative mood was associated with better performance for high-reactive participants but not their low-reactive counterparts. In the analytic condition, increasing negative mood was associated with better performance irrespective of emotional reactivity. Our results are consistent with the notion that negative mood engenders analytic thinking which may benefit response inhibition provided it does not increase task-incongruent cognitive load.
