Notes: 

When creating the ORCA picture database, we mainly relied on freely available material from other researchers (e.g. Brady et al. (2008) or Goh (2010)). 
Some additional objects and scenes were found via Google Image Search and Pixabay (https://pixabay.com). 
However, the copyright situation was unclear with some of the source material (e.g. Brady et al. (2008) wrote that they gathered the material from (commercial) databases and via Google Image Search). 
Moreover, the precise legal situation differs from region to region (e.g., some regions have fair use/dealing principles and/or exceptions for research, others do not).
Therefore, we provide the picture set with the terms of use described below. Exemplary pictures, which can be used for publications are provided on the OSF repository of the ORCA project.
