Motivation is key to the generation of creative ideas, intrinsic motivation is the core driving force of creativity. Researchers believe that individuals with higher intrinsic motivation will produce higher novelty and flexibility. Creativity may also be influenced by environmental cues, which are objects in the environment that individuals can use to solve problems. This study investigated the influence of intrinsic motivation and environmental cues on social creativity and whether there is an interaction effect of intrinsic motivation and environmental cues on the process of electronic brainstorming (EBS). The results showed that individuals generated more ideas (both in quantity and type) when presented with more cues. In this process, the influence of the number of cues on the fluency and flexibility of social creativity was regulated by intrinsic motivation. The more novel the cues, the higher the overall level of originality of the ideas generated by participants. In this process, the influence of the novelty of cues on the effectiveness and fluency of social creativity was regulated by intrinsic motivation. This study offers a fresh theoretical perspective on the complicated relationship between intrinsic motivation and creativity. Furthermore, it provides empirical evidence to inform training on social creativity for university students.
