The use of reinforcement is a central mechanism in the development of operant behavior. To reach good results in reinforcement-based interventions in basic, translational or applied research, it is important to identify preferred items to use with patients and participants. One way to accomplish that is through preference assessment methods. Most research on preference assessments employ tangible stimuli presented on a table. Although this method presents several advantages, some items and activities are not easily presented in this more traditional way. A computerized preference assessment test could solve some of these restrictions. Among the advantages is the possibility of keeping a nearly infinite digital stimuli database with pictures, sounds and videos. The objective of this research is therefore to present a computerized preference assessment test developed as an alternative to the table-top formats. This computerized tool was developed to run on any common, well-known browser and allows users to make updates to the database with new stimuli, insert information regarding the tests and create assessments according to specific objectives. More details on the operation of the tool, called "Choice Game", are presented.
