Once Upon a Story: Can a Creative Storyteller Robot Stimulate Creativity in Children?

Creativity is a vital inherent human trait. In an attempt to stimulate children's creativity, we present the design and evaluation of an interaction between a child and a social robot in a storytelling context. Using a software interface, children were asked to collaboratively create a story with the robot. We conducted a study with 38 children in two conditions. In one condition, the children interacted with a robot exhibiting creative behavior while in the other condition, they interacted with a robot exhibiting non creative behavior. The robot's creativity was defined as verbal and performance creativity. The robot's creative and non creative behaviors were extracted from a previously collected data set and were validated in an online survey with 100 participants. Contrary to our initial hypothesis, children's creativity measures were not higher in the creative condition than in the non creative condition. Our results suggest that merely the robot's creative behavior is insufficient to stimulate creativity in children in a child robot interaction. We further discuss other design factors that may facilitate sparking creativity in children in similar settings in the future.
