This study was designed to empirically examine equipment and system monitoring task features of the new MultiAttribute Task Battery-I I (MATB-II) and the original version (MATB). It also was intended to examine the effects of adaptive task allocation on system monitoring performance, as found in previous studies. In addition, two different computer displays (CRT and LCD) were used to test performance differences between the two systems in order to add historical fidelity to the study results. Sixty participants were randomly assigned to one of four experimental groups (MATB or MATB-II both on CRT or LCD), all receiving a return to manual control of the system monitoring task at mid experiment. A fifth group using the MATB on CRT with no task allocation was the control. Measures used to compare the two systems included percent of automation failures detected by participants in the system monitoring task and subjective workload. Results failed to show significance for the adaptive task allocation manipulation. However, significant differences in monitoring performance were found between the two systems. Implications for design of display and equipment features and future research are discussed.
While driver distraction has become one of the most studied topics in safety and in human factors, the focus has remained on the traditional elements of driver distraction. In this study, we manipulated the difficulty level of riddles to determine whether the cognitive processing associated with solving them would affect driving performance. Twenty-eight participants completed a series of eighteen short drives while undistracted or listening to a hard or easy riddles. Frequency of pressing the brake pedal, deviation in lane position, and average speed were analyzed. The results indicated that there was a main effect of riddle difficulty on how often the brake pedal was pressed. No main effects of measures on speed maintenance and lane position were found. While these results indicate there may be some differences related to difficulty of solving a problem while driving, further work is required to better quantify the effect.
This panel is comprised of current and prior student chapter officers, who will be discussing five selected themes influencing the success of Human Factors and Ergonomics Society (HFES) student chapters. These themes include: 1) administrative support, 2) chapter branding and funds, 3) chapter collaboration, 4) social activities, and 5) educational activities for chapters. We believe that these five pillars are necessary in providing a solid foundation for a successful and engaged chapter. Within each section, we discuss challenges and successes that our chapters have experienced. Additionally, we end with recommendations and suggestions that we hope other student chapters – HFES and otherwise – can use to bolster their group. We hope that these recommendations can foster the future success of aspiring Human Factors and Ergonomics Society student chapters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
