title: The informational impact of mood on effort mobilization: a study of cardiovascular and electrodermal responses.
abstract: The impact of mood on effort quantified as autonomic adjustments was investigated in an experiment. The authors induced positive versus negative moods with either 1 of 2 mood induction procedures (music vs. autobiographical recollection) that differed in the extent of required effort. Then participants performed an achievement task after demand appraisals were made. Results were as predicted. During the mood inductions, autonomic reactivity (systolic blood pressure [SBP], diastolic blood pressure, heart rate, skin conductance responses) was stronger in the relatively effortful recollection conditions than in the relatively effortless music conditions. Mood valence had no impact here. But in the context of task performance, the authors found (a) mood congruency effects on the demand appraisals that reflected subjectively higher demand in a negative than in a positive mood, and (b) stronger SBP reactivity in a negative mood compared with a positive mood. Furthermore, SBP reactivity during task performance was correlated with achievement.
