Psychological investigations involving the study of learning; memory, sensation, perception, cognition, motivation and emotion belong to experimental psychology. Experimental psychologists try to explain related phenomena in the way we apprehend and translate information into action. Experimental psychology dictates that all psychological processes can be explained through experimentation, such experimental methods consist of observation, manipulation of variables, predictions and the study of factors that can modify the result. Professionals who adopt this method want to know the behavior of a subject by manipulating variables in controlled environments. This branch of psychology has had a great contribution to the human understanding of the relationships between cognition and behavior.
