Original Research


BDataPro is a Microsoft Windows®-based program that allows for real-time data collection of multiple frequency- and duration-based behaviors, summary of behavioral data (in terms of average responses per min, percentage of 10-s intervals, and cumulative responses within 10-s bins), and calculation of reliability coefficients. The current article describes the functionality of the program. BDataPro is freely available for download from the authors’ institution websites.
