The Individual Differences in Performance Technical Group. The Individual differences technical group was established to serve HFES members who share an interest in any of the wide range of individual differences or variables that are believed to mediate human performance. Members of this TG share a common view that the study of these differences as related to human performance is not only useful but also may lead to better design of equipment, prediction of human task performance, operational environments, and training and selection. The domain of research and applied topics shared within this technical group includes a broad range of individual differences such as performance ability, gender, intelligence, education, training level, personality traits, and anthropometric variables. The Individual differences TG domain also includes investigating a wide range of social, cognitive, and biological origins of individual differences. The crucial unifying principle of the TG is the importance of such variables for the advancement of human factors theory, research, and application. The motto adopted as a guide for the group is “Prevent injury and improve performance and human-technology interaction by recognizing individual differences in human capabilities and limitations.” To find out more about HFES and their technical groups, visit HFES.org.
