Abstract Introduction The effects of training content consisting of examples and/or non-examples was studied on the acquisition of safety-related skills. Method Participants (N =160) were randomly assigned to first receive computer-based training on office ergonomics that included either no examples of safe or at-risk postures, safe examples only, at-risk examples only, or both safe and at-risk examples. Participants then attempted to classify as safe or at-risk various postures depicted in short video clips and demonstrate with their own posture the range of safe postures. Results Groups that were trained with both safe and at-risk examples showed greater classification accuracy and less error in their demonstration of safe postures. Training with only safe or at-risk examples resulted in a moderate amount of error and a consistent underestimation of risk. Conclusion Training content consisting of both examples and non-examples improved acquisition of safety-related skills. Practical applications The strategic selection of training content may improve identification of risks and safe work practices.
Highlights Training safety skills with safe and/or at-risk examples differentially impacts accuracy of learning and performance. Training with both safe and at-risk examples resulted in the greatest accuracy of safety skills. Training with only safe examples resulted in a consistent underestimation of risk. Learning transferred from the verbal skill to the physical performance skill.
