The focus of experimental psychology is on discovering the underlying processes behind behavior and the specific nature of mental life. This is in contrast to applied psychology, which employs psychological knowledge to solve real-world problems, and clinical psychology, which aims to treat mental illness with therapy and medication. Experimental psychology is a methodological approach rather than a subject and encompasses varied fields within psychology more broadly, many of which are studied using other methodologies like hermeneutics. Experimental psychologists have traditionally conducted research, published articles, and taught classes on neuroscience, developmental psychology, sensation, perception, consciousness, learning, memory, thinking, and language. Recently, however, the experimental approach has extended to motivation, emotion, and social psychology.

Other early experimental psychologists, including Hermann Ebbinghaus and Edward Titchener, included introspection among their experimental methods. 20th Century In the first half of the twentieth century, behaviourism became a dominant paradigm within psychology, especially in the United States. This led to some neglect of mental phenomena within experimental psychology. In Europe this was less the case, as European psychology was influenced by psychologists such as Sir Frederic Bartlett, Kenneth Craik, W. E. Hick and Donald Broadbent, who focused on topics such as thinking, memory and attention. This laid the foundations for the subsequent development of cognitive psychology. In the latter half of the twentieth century, the phrase experimental psychology has shifted in meaning due to the expansion of psychology as a discipline and the growth in the size and number of its sub-disciplines. Experimental psychologists use a range of methods and do not confine themselves to a strictly experimental approach, partly because developments in the philosophy of science have had an impact on the exclusive prestige of experimentation. In contrast, an experimental method is now widely used in fields such as developmental and social psychology, which were not previously part of experimental psychology. The phrase continues in use, however, in the titles of a number of well-established, high prestige learned societies and scientific journals, as well as some university courses of study in psychology. Methodology Experiments The complexity of human behaviour and mental processes, the ambiguity with which they can be interpreted and the unconscious processes to which they are subject gives rise to an emphasis on sound methodology within experimental psychology. Control of extraneous variables, minimizing the potential for experimenter bias, counterbalancing the order of experimental tasks, adequate sample size, and the use of operational definitions which are both reliable and valid, and proper statistical analysis are central to experimental methods in psychology. As such, most undergraduate programmes in psychology include mandatory courses in Research Methods and Statistics. Other Methods While other methods of research - case study, correlational, interview, and naturalistic observation - are practiced within fields typically investigated by experimental psychologists, experimental evidence remains the gold standard for knowledge in psychology. Many experimental psychologists have gone further, and have treated all methods of investigation other than experimentation as suspect. In particular, experimental psychologists have been inclined to discount the case study and interview methods as they have been used in clinicalcitation needed. Criticism Critical and postmodernist psychologists conceive of humans and human nature as inseparably tied to the world around them, and claim that experimental psychology approaches human nature and the individual as entities independent of the cultural, economic, and historical context in which they exist. At most, they argue, experimental psychology treats these contexts simply as variables effecting a universal model of human mental processes and behaviour rather than the means by which these processes and behaviours are constructed. In so doing, critics assert, experimental psychologists paint an inaccurate portrait of human nature while lending tacit support to the prevailing social order.citation needed Three days before his death, radical behaviourist B.F. Skinner criticized experimental psychology in a speech to the American Psychological Association for becoming increasingly mentalistic - that is, focusing research on internal mental processes instead of observable behaviours. This criticism was levelled in the wake of the cognitive revolution wherein behaviourism fell from dominance within psychology and functions of the mind were given more credence.citation needed Notes ^ a b Omar Khaleefa Summer 1999.
