Statistical approaches to identifying lapses in psychometric response data.

Psychon Bull Rev. 2021 Apr 6. Review. Online ahead of print.

PI: T.K. Clark

Note: From the article: “Utilizing signal-detection theory, psychometric curve fits are widely used to quantify an observer’s performance. Subject lapses caused by loss of attention can cause fit parameters to fall far from actual values. Accurate psychometric curve fits are critical to ensure accurate and appropriate experimental conclusions. We test a novel lapse-identification algorithm that simulations show reduces the impact of lapses across a wide range of underlying lapse rates. Further simulations show the algorithm to be effective across a broad range of experimental conditions.”

Journal Impact Factor: 3.910

Note: The particular spaceflights are not identified in the available English abstract. From the abstract: “The review examines various parties of oxygen-dependent human adaptation to microgravity belonging to different levels of the integral system organization. Particular emphasis has been placed on the cellular sensing systems of immediate and chronic reactions to altered O2 delivery. The authors expound the key oxygen sensors and heterogeneity of the sensing mechanisms. They also concern themselves with the role of O2 active forms and O2-sensing elements developing in the spaceflight environment.”

Note: From the abstract: “Next phase of experiment TEST is aimed to evaluate microbial viability after a prolonged external exposure on the International space station (ISS). Methanogenic archaea isolated from various habitats have been tested in ground facilities for the ability to survive exposure to such open space factors as UV and vacuum. Methanosarcina mazei S-6T (VKM B-1636T) was found to be the most viable and, therefore, suitable for the experiment.”
