The Society of
Experimental
Psychologists

The Society of Experimentalists was founded by Edward Bradford Titchener in 1904. Titchener’s design for his “Experimentalists” was that it be an ongoing workshop, with “members visiting labs, studying apparatus, and hearing and commenting on reports of ongoing research.”

History of SEP
The first meeting of the Society of Experimental Psychologists – then called “The Experimental Psychologists”, or “The Experimentalists” for short – was held at Cornell University in Ithaca, New York, on April 4 – 5, 1904. The meetings then, and for many years thereafter, were presided over by Edward Bradford Titchener. Researchers from universities including Cornell, Yale, Clark, Michigan, and Princeton attended these early meetings, with Chicago and Iowa soon joining. Research papers were read and discussed by established researchers and tyros alike.
As the number of practicing experimental psychologists grew nationally, along grew discussions concerning the limits that should be placed on membership in the group: Should it be kept small to ensure a manageable series of conferences; or should it be open to all interested, practicing experimental psychologists? The decision was made to keep it small-to follow the so-called Academy model-and eventually Fellows of the society were instrumental in the founding of an alternative organization, called The Psychonomic Society, to serve the needs of broader representation and communication (see Dewsbury & Bolles, 1995 for details). During these early years, the total membership in the Experimentalists ranged around 35 individuals. Learn More
About Us
The Society of Experimentalists was founded by Edward Bradford Titchener in 1904. Titchener’s design for his “Experimentalists” was that it be an ongoing workshop, with “members visiting labs, studying apparatus, and hearing and commenting on reports of ongoing research.”
The Society has continued to meet annually in the years since, except for the war year 1918 and the COVID pandemic years 2020 and 2021. Upon Titchener’s death in 1927 the club was reorganized into The Society of Experimental Psychologists. The Society typically holds meetings in the spring, scheduled and organized by a member, who serves on the Executive Committee of the Society for that year. The meetings are open to all members of the Society, and to students and faculty from the host university as invited by the organizer.
The meetings are plenary and involve papers from various members of the society. The society currently admits at least 6 new members annually from among the leading experimentalists in North America. It has a current membership of 281 individuals, about 5 – 10% of the practicing experimental psychologists. The mission of the society is “To advance psychology by arranging informal conferences on experimental psychology.”
