Study Materials

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. 

The following citation is appropriate for referencing the use of the stimuli provided for download:

Nosek, B. A., Smyth, F. L., Hansen, J. J., Devos, T., Lindner, N. M., Ratliff (Ranganath), K. A., Smith, C. T., Olson, K. R., Chugh, D., Greenwald, A. G., & Banaji, M. R. (2007). Pervasiveness and correlates of implicit attitudes and stereotypes. European Review of Social Psychology,18, 36-88.

The anonymous data collected on the Project Implicit Demonstration website is made 
publicly available so that scientists journalists, educators, and others can use it to better understand attitudes and stereotypes. Project Implicit also maintains a list of published research papers that utilize data from the Project Implicit Demonstration website.

Age faces

6 young (3 male, 3 female) and 6 old (3 male, 3 female) morphed white faces cropped at forehead and chin. From the “age attitude" task.

Asian/white faces and American/foreign landmarks

6 asian (3 male, 3 female) and 6 white (3 male, 3 female) head-shot sketches of faces. 6 American and 6 foreign landmarks (e.g., Statute of Liberty and the pyramids). From the “Asian American stereotype" task.

Nationalism task stimuli sets.

Tasks use a similar set of images and words – in most of these there are 3 images per country – the flag, an outline of the country, and an image of the current leader, famous figure, or prominent landmark. From the international “Nationalism" tasks.


8 images (4 abled and 4 disabled) representing abilities in the form of street signs or related representational forms. From the “disability" task.

Kids faces

8 black (4 male, 4 female) and 8 white (4 male, 4 female) morphed head shots. From the “child race" task.

Native/white faces and American/foreign landmarks

Update currently in progress.


6 head shots of U.S. presidents: Bush, Clinton, Jefferson, Kennedy, Lincoln, Nixon, Reagan, Roosevelt. Also, two of 5 recent presidents (Clinton, Reagan, Carter, Ford, Nixon). From the “Presidental approval" task.

Race faces

6 black (3 male, 3 female) and 6 white (3 male, 3 female) morphed young faces cropped at forehead and chin. From the “race attitude" task.

Religion items

5 Jewish and 5 other religious images (e.g., menorah and cross). From the “religion" task.


2 gay (male), 2 lesbian, and 2 heterosexual image representations in as restroom and cake-topper figurines. From the “sexuality attitude" task.

Dark skin and light skin faces

12 dark-skinned (8 male, 4 female) and 12 light-skinned (8 male, 4 female) sketched faces. The same face is represented in light and dark skin. From the “skin-tone attitude" task.

Weapons and faces

Same race faces as above. 7 weapons and 7 harmless objects. In the old version of the task, weapons are ‘classical’ weapons that are not seen or used frequently in modern life (e.g., battle axe, mace, classical revolver). In the new version of the task, weapons are contemporary weapons (e.g., handgun, shotgun, brass knuckles).

Weight faces

10 fat (5 male, 5 female) and 10 thin (5 male, 5 female) morphed faces of multiple ethnicities. The same face is represented as thin and fat. From the “weight attitude" task.
