While Wilhelm Wundt's work greatly influenced the entire field of psychology, the school of psychology in which he worked was experimental psychology and in 1875 he founded the Institute for Experimental Psychology. Experimental psychology applies experimental methods (e.g. types of experimental studies, reliability, validity, research design, etc.) to study psychological processes. The school of experimental psychology is vast as it applies to the study of psychological concepts in all other schools of psychology (e.g. cognitive psychology, developmental psychology, social psychology, etc.)   _{Your Comment}
