Abstract

This project is designed to develop an objective test to identify sleepiness in people with jobs where errors can be dangerous; for example, factory workers, pilots, or soldiers. My role in the project was to collect and analyze data from cognitive tests to search for factors associated with sleepiness. I tested for correlations between a variety of factors in several tests, including the PVT (Psychomotor Vigilance Task, testing reaction time) and the LOT (Line Orientation Test, testing the subject’s spatial orientation skills). So far, I have considered: correlations between two metrics in the same test (ex: errors on a test vs mean reaction time on the same test), differences between subjects of different genders, differences based on cognitive test order, and whether there is a learning effect over the course of the study. The LOT seems shows inconsistent effects in different metrics over the course of the study, and requires further analyses. The PVT does not demonstrate any learning effect.
