Computational Modeling Approaches For Task Analysis In Robotic-Assisted Surgery
… to perform certain difficult or complex surgical tasks in an autonomous manner. The feasibility of current robotic surgery systems to record quantitative motion and video data motivates developing descriptive mathematical models to recognize, classify and analyze surgical tasks. Recent advances in …

A task analysis of the withdrawer re-engagement event in emotionally focused couples therapy
A discovery-oriented task analysis was conducted to delineate what therapist interventions, behaviors, and responses and client emotional processes are involved in successful withdrawer re-engagement in Emotionally Focused Couples Therapy (EFT). EFT is an empirically validated approach to treating …

Development and validation of a methodology for comprehensive performance assessment of complex tasks
A new task analysis methodology was developed to provide objective information on complex tasks. A complex task was broken down into observable elements and unobservable elements that were inferred to have taken place in support of the observable actions. Subject matter experts (SMEs) were used to …
