Stimulus Materials for Social and Behavioral Research
The following stimulus sets are made available for academic research purposes. All stimulus sets were originally prepared for research on the Project Implicit demonstration and research websites.
Stimulus sets are stored as .zip files and images are in either .jpg or .gif format. All images are small and designed for use in rapid judgment tasks. Text stimuli are not available here. Please see Nosek (2005) or the citations below for stimulus words used in Project Implicit research.
