Resources in our repository exist in different languages, for different types of materials, as well as for different categories of material.

Thanks to the use of Standards for the storage and description of these resources, they can all be listed from a single access point, as demonstrated here.

Fribbles Stimulus Sets
Fribble stimuli used in several experiments. Within each Fribble species, the exact shape, color, and texture of the main body and the approximate location and interrelationships between appendage parts are held constant for all exemplars. Colors and textures of appendage parts are also similar (although not identical) across exemplars. The main aspect that changes from exemplar to exemplar in a species is the exact shape of the appendage parts.

Diagnostic Color Objects
Color images of many diagnostic color objects, e.g., a banana. Objects are shown in typical and atypical colors. There are also control sets of neutral color objects. The orignal set were used as stimuli in Naor-Raz, Tarr, & Kersten (2003)

Grayscale pictures of 31 chairs -- Bruno Rossion
Grayscale pictures of 31 chairs garnered from various sources by Bruno Rossion at the Universite Catholique de Louvain. Bruno has scaled all of the images to the same size, orientation, and brightness. Bruno asks that if you are going to use the chairs, please contact him at and let him know what you are up to. The images are STANDARD COLORS grayscale PICTS.

Colorized Snodgrass and Vanderwart pictures -- Rossion & Pourtois (2004)
The authors have created a new set of stimuli based on the widely used line drawings of Snodgrass and Vanderwart (1980). These 260 stimuli contain diagnostic texture and color information. Normative data (naming agreement and latencies, complexity, familiarity, imaginability) for these new stimuli have been collected (Rossion & Pourtois, 2004). Their data shows that surface information, color in particular, greatly facilitates object recognition.

If you download the set and wish to use it in an experimental/clinical study, a donation of $30-$50 to help defray their costs would be most welcome. You can send correspondence about contributing to Bruno Rossion.

Change Blindness Scenes
This set of scenes were used as stimuli in the studies reported in Aginsky & Tarr (2000) set contains many variants of individual scenes. Variants were generated by either moving or changing the color of some element of the scene. The images are color PICT files.

Lexical norms for pictures, Martein (2005)
This work presents the results of a normative data collection study of 216 pictures which can be used in a wide range of cognitive experiments. Black-and-white line drawings of 216 objects, belonging to 20 large semantic categories, were rated by a sample of 300 first-year psychology students at the University of Ghent. These ratings provided data on several variables of central importance to cognitive processing and memory functioning: name agreement, concept agreement, familiarity, visual complexity and image agreement. The following semantic categories were included in the set: 1. Article of clothing, 2. Birds, 3. Electronical appliances, 4. Fish, shells, ..., 5. Flowers, plants, ..., 6. Food, 7. Fruit, 8. Furniture and decoration, 9. Insects, 10. Kitchen-utensils, 11. Mammals, 12. Miscellaneous, 13. Musical instruments, 14. Parts of a building, 15. Parts of the human body, 16. Reptiles and amphibians, 17. Tools, 18. Vegetables, 19. Vehicles, 20. Weapons

Norms for timed picture naming
The UCSD Center for Research in Language is engaged in a large international study to provide norms for timed picture naming in seven different languages (American English, German, Mexican Spanish, Italian, Bulgarian, Hungarian, and the variant of Mandarin Chinese spoken in Taiwan). They currently have data for over 500 pictures.
