Adapting the task-taxon-task methodology to model the impact of chemical protective gear

摘要

The Task-Taxon-Task method (Anno et al. DNA-TR-95-115, 1996) is a statistical modeling approach to predict performance decrements on behavioral tasks in response to various stressors. We describe the basics of the T3 method and our approach to adapting it to handle more acute stressors, which can require decompo sition into task networks via logical or empirical analysis. We provide an illustrative example showing how the method can be used to account for performance decre ments in manual tasks associated with wearing protective gloves. This illustration provides a substantive application in which the current T3 method can be augmented to account for performance decrements in a new sub-domain, while additionally pro viding lessons for extending the method to new stressors, performance domains, and behavior modeling systems.
