Whose Signals Are Being Amplified? Toward a More Equitable Clinical Psychophysiology

Abstract

Research using psychophysiological methods holds great promise for refining clinical assessment, identifying risk factors, and informing treatment. Unfortunately, unique methodological features of existing approaches limit inclusive research participation and, consequently, generalizability. In this brief overview and commentary, we provide a snapshot of the current state of representation in clinical psychophysiology with a focus on the forms and consequences of ongoing exclusion of Black participants. We illustrate issues of inequity and exclusion that are unique to clinical psychophysiology and consider intersections among social constructions of Blackness and biased design of current technology used to measure electroencephalography, skin conductance, and other signals. We then highlight work by groups dedicated to quantifying and addressing these limitations. We discuss the need for reflection and input from a wider variety of affected individuals to develop and refine new technologies given the risk of further widening disparities. Finally, we provide broad recommendations for clinical-psychophysiology research.
