Mental processes refer to the internal, cognitive activities that encompass a wide range of functions including perception, attention, memory, language, problem solving, reasoning, decision making, and understanding emotions. This research area seeks to understand how these processes operate, interact, and influence behavior and mental health. Researchers in this field may use various methodologies such as experimental psychology, neuroimaging, computational modeling, and behavioral studies to investigate mental processes and their underlying mechanisms. Ultimately, the goal of this research is to gain a deeper understanding of the human mind and behavior.
