Stimulus Materials for Social and Behavioral Research - Prepared by Project Implicit and Brian Nosek

The following stimulus sets are made available for academic research purposes. All stimulus sets were originally prepared for research using the Implicit Association Test at Project Implicit demonstration and research websites. Stimulus sets are stored as .zip files and images are in either .jpg or .gif format. Text stimuli are not available here, see Nosek (2005, JEP:General) or the citations below for stimulus words used in Project Implicit research. All images are small and designed for use in rapid judgment tasks.

The following citation is appropriate for referencing use of these stimuli (except for Nationalism stimuli, those data are unpublished so reference the website as the source):
