Design overview
We designed a between-subject experiment. The
participants were randomly assigned to one of two
conditions (happy and sad). We primed them with the
mood assigned by using different movie clips. 27
participants were assigned to the happy condition, and
31 to the sad condition. After watching a short movie
clip, they completed a mood manipulation check
questionnaire, which asked them to indicate the level of
agreement with words describing the mood they just
experienced. They then received a searching task,
searched for some information over the Web, and
responded to a questionnaire on the searching process,
task, and their background.
