Internet Resources for Experimental Stimuli

We have compiled a list of Internet resources for both auditory and visual stimuli. All links have been tested as of May 2015. If you have stimuli that you would like to add to this list (or if you notice a broken link), please contact us. As always, please cite the appropriate investigator upon publishing any paper using downloaded stimuli.

Verbal Stimuli
Sets of normed word pools

Normed affective word lists

Sound Stimuli

Various sound files including famous spoken quotes

Social and Emotional Stimuli: Faces and Photos

Stirling/ESRC 3D Face Database, a free-to-use database of 2D and 3D faces with varying viewpoints, lighting, distance, and expressions.

Computer generated faces manipulated along 9 trait dimensions, from Alex Todorov’s lab at Princeton.

Classic emotional stimuli (such as the IAP picture set) are available

Open Affective Standardized Image System (OASIS)

Emotional face set from CMU

Information on Face Recognition

A stimulus set including 1,612 PNG-format color images generated along an image morph continuum between the average male face and the average female face from a large database of feature-tagged face images.

Objects and Scenes

Many good images of cars, motorcycles, airplanes, faces, doors and scenes (from Caltech)

Objects and scenes of mixed quality (University of Surrey)

Color-calibrated natural scenes

A good database of objects, scenes, birds, butterflies, textures, with links to other sites (Illinois)

Real objects (from Columbia)

Photographs of people, scenes and objects (from Berkeley)

Computer-generated objects (from Princeton)

Biological Motion

Large set of point-light displays, with both human and nonhuman actors (from Temple)

Change Detection

Free flicker demos (from Ron Rensink)

Websites with links to many stimulus databases

Database of various image types, mostly from computer vision sources (quality is mixed)

An older website with decent visual stimuli


Links to other lists of sound files (some links broken, some not so good)

Create your own stimuli

Morph faces

Make anaglyphs with Photoshop

For Mac users, record and manipulate voices easily using Garageband
