Thinking out of the box

Abstract Metaphor production is a creative process of thinking out of the box, which can be of great communicative value to language users. In this study, we explored how metaphor production can be stimulated by different types of cues in an internet environment. Participants (N = 318) were invited to co-create a metaphorical campaign slogan in a social media setting with randomly selected sets of real campaign slogans. We measured how linguistic (metaphor markers) and social media cues (likes) prompt direct metaphor. Results show that the metaphor marker ‘so’ stimulated metaphor production. Likes for previously posted metaphorical slogans did not affect the creation of a metaphor. We found a correlation between the actual and self-perceived creativity of the co-created slogans. Besides, the co-created metaphors both echoed and deviated from previously posted campaign slogans, leading to different degrees of creativity. Co-creation in a social media setting seems a fruitful environment for metaphor production.
