This study asked whether two picture prompts, one depicting a critical incidence, called ‘losing a cellphone’ and the other without a critical incidence, namely ‘using a cellphone’ made a difference to the content of story writing. The study also investigated which picture students preferred, one with or without a critical incidence. High school students (N = 101) participated in a story writing task where one of the two prompts was assigned to each student. A survey for preference was implemented to 185 high school students. The results show that when stories were composed under time constraint, whether the critical incident was present or absent was not a significant factor in the writers’ creation of better or worse content in writing. However, the critical incidence in the picture might be considered an attractive tool for story writing, promoting writers’ positive attitude to the task.
