Signal detection theory can be used to better understand cognitive fatigue
A team of New Jersey researchers has shown that changes in perceptual certainty and response bias, two central metrics of signal detection theory (SDT), correlate with changes in cognitive fatigue. They also show that SDT measures change as a function of changes in brain activation. This finding was reported in
Frontiers in Psychology on January 15, 2021, in the open access article Using Signal Detection Theory to Better Understand Cognitive Fatigue (doi:10.3389/fpsyg.2020.579188).

Study Seeks to Better Understand How MS Affects Memory 4.5 (19)
A new research project will seek to better understand the biological processes that drive memory problems in people with multiple sclerosis (MS), as a better understanding of these processes may open new avenues for intervention.
The four-year study is titled “Neuroimaging of Hippocampally Mediated Memory Dysfunction in Multiple Sclerosis,” and received funding totaling $651,997 from the National Multiple Sclerosis Society.
Its principal investigator is Joshua Sandry, PhD, assistant professor of psychology at Montclair State University. Also collaborating on the study is Ekaterina Dobryakova, PhD, a research scientist in the Center for Traumatic Brain Injury Research at Kessler Foundation. She will oversee the clinical project, including advanced neuroimaging studies conducted at the Rocco Ortenzio Center for Neuroimaging at Kessler Foundation.
Researchers receive $651,997 funding to study memory dysfunction in MS
Researchers at Montclair State University and Kessler Foundation have received funding totaling $651,997 from the National Multiple Sclerosis Society to measure memory-related abilities in individuals with and without multiple sclerosis (MS) for clues to how such cognitive processes are altered by MS. Joshua Sandry, PhD, assistant professor of psychology at Montclair State and Ekaterina Dobryakova, PhD, research scientist in the Center for Traumatic Brain Injury Research at Kessler Foundation, collaborate on the 4-year study, titled Neuroimaging of Hippocampally Mediated Memory Dysfunction in Multiple Sclerosis.
