# Welcome to BITTSy The **Behavioral Infant and Toddler Testing System (BITTSy)** was developed at the University of Maryland College Park. It is designed to run classic infant and toddler testing paradigms such as headturn preference procedure, preferential looking procedure, visual fixation/habituation procedures, and conditioned headturn procedure, all within a single freely-available program, interfacing with standard off-the-shelf hardware to allow for standardization and consistency across testing sites and research groups. In the following sections, you will find more information and guidance on using BITTSy for your own research. *The development of BITTSy was funded by **NSF BCS1152109**, "New Tools for New Questions: A Multi-Site Approach to Studying the Development of Selective Attention".* --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
