The key components of experiments are stimuli of an outstanding quality. They are to be selected with meticulous care, as they are the cornerstone of experiments and often the primary target of critics. Nevertheless, creating stimuli, pictures in particular, requires time - sometimes up to several months. This work can be avoided by purchasing pictures from existing photo banks (which may not necessarily have been developed for scientific purposes). In research however, scientists do not only need pictures; these pictures also require very specific features. For instance, a scientist developing a project on memory may require pictures of both familiar and unfamiliar objects. Simultaneously, the same scientist will try to avoid the influence of confounding features which influence memory performance. Consequently, neglecting to control for confounding features significantly undermines the results’ validity.  


In 2009, the first stimuli of the Bank of Standardized stimuli (BOSS) were created and normalized in order to provide scientists with normative high quality visual stimuli to be used in cognitive and psycholinguistic research. In 2010, the first paper describing the project was published in PLoS ONE (Brodeur et al., 2010). Our goal was to develop a normative set, offering features that satisfy most research needs. For this reason, the BOSS is continually growing with the addition of pictures and norms. However, this work cannot solely be undertaken by our team; in part due to the lack of financial support. Therefore, we hope that BOSS users will join us in our effort to develop the BOSS and make it an incontrovertible tool in cognitive and psycholinguistic research.   


The present website was built to centralize and disseminate information and data related to the BOSS. The information will be provided from both our team and other teams who may have an interest in sharing new material. This website will present the latest updates, the description of the norms, unpublished information about the images and the objects, and tips on how to conduct a normative study. All data can be downloaded. You can contribute to this site by sending your comments or by contacting Dr. Mathieu Brodeur (mathieu.brodeur@gmail.com).
