The programme is built from submitted symposia (80-minute sessions of three to four speakers integrating diverse perspectives on a common topic), 15-minute submitted talks, 5-minute flash talks, standard posters, pilot-project posters sharing initial findings or research plans, and teaching posters on methods for teaching psychology. New for 2027, submissions are typed as empirical research, systematic reviews, meta-analyses and meta-syntheses, or methods and applications contributions (measurement, experimental design, statistical modelling, computational approaches); pre-registered research is especially encouraged, and each submission is assigned to a program theme from its subject area and keywords. All presenters present on site in Seattle.
