The present study examined comprehensibility of a set of safety pictorials, and then employed a training procedure (providing short verbal descriptions of the pictorials) to enhance comprehension and retention. Comprehension was tested for all participants prior to training, and after 1 week. Additionally, comprehension was also tested for some participants immediately following training, and 6 months after training. Also manipulated was the content of instruction (supplying either the pictorial's associated verbal label or verbal label plus a more detailed explanatory statement), and difficulty level (‘easy’ versus ‘difficult’ to understand pictorials, as determined by prior research). The results showed that training led to a significant increase in pictorial comprehension.
