Sadness and fear, but not happiness, enhance inhibitory behavior, according to a study published in Cognition & Emotion.
Research has shown that emotions play a key role in shaping behavior and cognition, particularly in relation to executive functions like attention, problem-solving, and inhibition. While positive emotions like happiness are generally associated with cognitive flexibility and exploration, the role of negative emotions like fear and sadness in executive control is less understood.
Justin Storbeck and colleagues addressed this gap by exploring the specific effects of discrete emotions on inhibitory processes, building on frameworks such as the emotion and goal compatibility theory, which suggests that emotions enhance executive functions based on their relevance to achieving specific goals.
Experiment 1 included 141 participants who were randomly assigned to one of four emotion conditions (sadness, fear, happiness, or neutral), which were induced using images from the International Affective Picture System (IAPS). The anti-saccade task, which measures oculomotor inhibition, required participants to look away from a visual cue. Accuracy was recorded as the primary measure of inhibitory control. Across all experiments, participants also completed a manipulation check to assess the effectiveness of the emotion induction and were asked to report their emotional states before completing the inhibition tasks.
Those in the sadness and fear conditions showed significantly higher accuracy in the anti-saccade task, successfully resisting reflexive eye movements toward the cue. This result suggests that sadness and fear improve inhibitory control, helping participants focus by minimizing distractions compared to happiness and neutral conditions.
Experiment 2 involved 155 participants. After emotional induction through IAPS images, participants completed a negative priming task. This task measured interference inhibition by requiring participants to identify the larger of two circles, with interference trials placing the larger circle in the same location as a previously irrelevant smaller circle to test their ability to ignore past irrelevant stimuli.
Contrary to expectations, sadness impaired performance on the negative priming task, with participants in this condition demonstrating lower interference inhibition. The happiness, fear, and neutral conditions did not significantly affect performance, indicating that sadness may reduce inhibition when it involves filtering out previously relevant information.
Experiment 3 involved 150 participants, who following emotion induction, performed a backward inhibition task, where they switched between goal sets (e.g., identifying based on shape, size, or orientation). Backward inhibition was measured by comparing reaction times for returning to a previously relevant goal set versus a new one, assessing participants’ cognitive inhibition in suppressing prior cognitive sets.
Sadness and fear conditions showed stronger cognitive inhibition, as participants took longer to respond when switching back to a previous goal set. This suggests that sadness and fear improve cognitive inhibition by helping participants suppress previously relevant information, aiding in goal maintenance during task shifts.
In Experiment 4, 154 participants were again divided into sadness, fear, happiness, and neutral conditions, with an additional anger condition to test whether the approach orientation of anger might affect inhibition. They completed a go/no-go task, requiring rapid responses to a “go” stimulus and inhibition of responses to a “no-go” stimulus. Behavioral inhibition was measured by the accuracy in withholding responses on no-go trials.
Sadness and fear conditions demonstrated higher accuracy on no-go trials, indicating better behavioral inhibition than the happiness and anger conditions. Anger, in particular, impaired inhibition, suggesting that withdrawal-oriented emotions like sadness and fear enhance inhibitory control more effectively than approach-oriented emotions.
One limitation is that the study did not include other negative emotions, such as disgust, that might also influence inhibitory control.
Overall, this research suggests that sadness and fear enhance inhibitory control, helping individuals focus on relevant tasks by suppressing irrelevant distractions or automatic responses. These findings challenge the traditional view that negative emotions always impair cognitive performance.
