👉 In science, a psychophysiologist is a scientist who studies human behavior and mental processes. They study how people perceive, interpret, and respond to stimuli, as well as how these experiences influence their behavior in various situations. Psychophysiologists use a variety of methods, including experiments, observational research, and theory-based analysis, to gain insights into the mechanisms that underlie human behavior. The field encompasses a wide range of fields such as psychology, neuroscience, and cognitive science.
