    Investigating the effects of cognitive overload in a simulated manufactoring task

    If traditional ergonomics optimizes jobs with a focus on the body, cognitive ergonomics optimizes jobs based on the mind. Since interaction with technology has been increasing, understanding the mental workload of a task becomes a critical factor when analyzing performance and safety. Cognitive overload can be described as a situation where the mental demands of a task are greater than the individual’s ability to successfully complete the given task. It is known that this stressful state impedes task performance and can even increase muscle activity. This indicates that a job requiring a higher cognitive demand could lead to more injuries; however, the literature is limited when observing this effect in simulated manufacturing tasks. It is also known that blink rate and pupil size change during workloads in stationary tasks, suggesting ocular metrics could be a viable measure of mental workload. This relationship, however, has not been studied in a task requiring full body movement. Therefore, the goals of this study are threefold: 1) further understand the relationship between cognitive overload and task performance/safety; 2) determine if ocular metrics are a viable measure of mental workload during a task requiring full body movement; and 3) analyze any potential relationship between muscular activity and ocular metrics

    Preventing response-based inhibition processing retrieval: SNP disengagement

    Reactions to the position of a new target stimulus are slower when it appears at a former distractor-occupied, rather than a new, location (i.e., spatial negative priming [SNP] effect). The SNP effect represents maladaptive processing. Accordingly, its observed prevention pursuant to certain motivational factors is helpful, although the disengagement mechanism is undefined. Here, we tested the possibility that SNP prevention is achieved by blocking a response-based retrieval route that normally accesses stored response inhibition information that causes SNP. We incorporated many: 1 location-response mappings into a traditional SNP design, which allowed the use of an earlier (inhibited) distractor response but not its location (distractor-response repeat [DRR] trial). Uncued, latency for the DRR trials exceeded those of control trials, signifying the presence of a response-based retrieval route. When the DRR was validly cued, this latency difference was eliminated, indicating that this route had been blocked as a means of disengagement
