This study tested mood effects on product evaluation, varying information type and time pressure. In this experiment, happy or sad moods were induced in participants, then they were asked to evaluate products. The results showed that in the happy mood/non-time-pressure condition, a favorable evaluation was seen when complete information was provided compared to incomplete. However, when time pressure was induced, no such difference was observed. On the other hand, in the sad mood/non-time-pressure condition, there was no difference in evaluation between complete and incomplete information, but when time pressure was induced, a less favorable evaluation of products was seen under incomplete relative to complete. The results provide support for the process in which participants depend on their mood as a source of information when inferring about missing information under reduced cognitive capacity.
