Latent Cognitive Conflict’s Impact on Effort-Related Cardiac Response: First Evidence

The impact of latent cognitive conflict—conflict unrelated to an instrumental task—on effort mobilization is still understudied. Administering either conflict-related (i.e. incongruent) or non-conflict-related (i.e. congruent) Stroop primes in an attention task corroborated our prediction that latent cognitive conflict should increase effort-related cardiac reactivity.
