Participants completed military vehicle identification training and testing, along with card-sorting and similarity-rating tasks. The data enabled us to predict up to 84% of identification confusion errors and to understand the mental representation underlying these errors. These methods have potential to improve training and reduce identification errors leading to fratricide.

Recommendations were provided to the case study food pantry for enhancing safety and productivity. Further research is needed to assess the generalizability of our findings to other food pantries.

The purpose of this study was to conduct a human factors and ergonomics exploratory evaluation of an American international coffee shop located in the developing country of Honduras. Task analysis and ethnography techniques were utilized, observing and interviewing workers to determine basic tasks, task performance, and any issues encountered in the workplace. Analyses revealed aspects that may potentially affect task performance including multitasking, overload, and environmental factors (e.g., lighting, workspace layout, and signage). Recommendations are then provided to enhance the interaction between workers and coffee shop environments in the developing world.
