ECOS database

ECOS (Ecological Congruity Object-Scene) database is a collection of natural scenes optimized for standard visual tasks but that can easily be accommodated for other paradigms. A key aspect of this database is that it includes semantically matching and mismatching object-scene combinations which can be used to study many cognitive processes such as object-scene integration and segregation, object detection and identification and even visual search. The images included in this data set have already been used in attention and memory studies.

Our aim is to offer a ever-updating site for researchers from all around the world to find sets of ecological stimuli for research purposes. In addition, we aim at providing a few examples of scripts of very common cognitive tasks with natural scenes for early-career scientists who want to initiate in programing with languages such as MatLab's Psychtoolbox and Python's Psychopy.
