Using the method of emotional design, this study investigates whether external emotional
induction、internal emotional design and different emotional types have influence on creative problem
solving and the differences between these influences in multimedia learning. Experiments using 3
(external emotions evoked: positive emotions induced + negative emotions induced+ neutral emotions
induced) × 3 (internal emotional design: positive emotions design + negative sentiment+ neutral
emotional design) of the three factors between subjects experimental design. At the same time, in the
experiment, the unconventional use test was selected as the creative problem solving topic (the use of a
newspaper and the use of a water bottle), and the fluency, flexibility, uniqueness of creative thinking and
the emotional changes of the participants during the experiment were taken as the dependent variables.
The results showed that (1) in the external-emotion-induced emotions, positive emotions can promote
the production of thinking fluency, uniqueness and flexibility. Negative emotions can promote the fluency
and uniqueness of thinking. There was no significant difference between positive emotions and negative
emotions in the fluency and uniqueness of thinking.(2) In the condition of internal emotional design,
only internal positive emotions can promote the output of thinking fluency and flexibility.(3) In terms of
thinking flexibility, the interaction between external emotional induction and internal emotional design is
