Cognitive psychology is a branch of psychology that focuses on studying mental processes such as attention, memory, language, problem-solving, and decision-making. Researchers in this field seek to understand how people perceive, think, and remember information, as well as how these processes influence behavior. Cognitive psychologists use a variety of research methods, including experiments, brain imaging techniques, and computer simulations, to investigate these mental processes and their underlying mechanisms. This research has important implications for understanding factors that influence human behavior, such as learning, decision-making, and problem-solving.
