The Society for Experimental Social Psychology (SESP) is one of the leading associations of social psychologists in North America. SESP is in many respects a different type of organization to EAESP. Membership is more selective, and there are no graduate student members. The primary activity of SESP is the organization of an annual meeting, which usually takes place in October.

In an attempt to foster greater awareness of and communication between SESP and EAESP, there have so far been three joint meetings, one unofficial and two official. The objective of these joint meetings is to strengthen the ties between social psychologists in Europe and North America, and to expose each set of members to the research being conducted on the 'other' continent.The first was a small, informal affair, which took place in Paris in 1977. The second, much larger meeting was the first formal joint meeting. It took place in Leuven/Louvain-la-Neuve, Belgium, in July 1992. The third was the first joint meeting to take place in North America. It took the form of an 'expanded' SESP meeting and it was held in Washington, DC, in September 1995.

Unlike other meetings sponsored or co-sponsored by the EAESP, there is no fixed 'cycle' of joint EAESP-SESP meetings. Rather, the Executive Committee responds to proposals to host such a joint meeting, and liaises with the SESP committee in deciding whether to proceed with such a proposal.
