Two experiments examined the processes by which positive mood influences attitude change under high and low message elaboration conditions. To examine elaboration, Experiment I included individuals who differed in their need for cognition, and Experiment 2 manipulated the relevance of the message. In each study, Ss were exposed to a persuasive communication following a positive or neutral mood induction. In both studies, positive mood produced more positive attitudes toward the advocacy, but positive mood influenced the positivity of Ss' thoughts only under high-elaboration conditions. Path analyses showed that positive mood had a direct effect on attitudes in the low-elaboration conditions but influenced attitudes indirectly by modifying the positivity of thoughts in the high-elaboration conditions.
