About

This document is a web-book that describes in detail how the PLAY project team is collecting, curating, analyzing, and sharing data.

Themes

The Play & Learning Across a Year (PLAY) Project has three major priorities or themes.

Behavior

We believe that developmental science can and must focus on behavior (Adolph 2020).

Video

We believe that video is a uniquely powerful and inexpensive tool for capturing behavior and analyzing it. And we also believe that video has unheralded and under-exploited power as a means of documenting research procedures (Adolph, K.E., Gilmore, R.O., & Kennedy, J.L. 2017; Gilmore and Adolph 2017).

Openness and transparency

We believe that psychological science will be more robust and reproducible, make important advances more quickly, and have a greater impact on society if we embrace openness and transparency throughout our work.

PLAY is committed to open science. We are developing our protocol in the open and publishing it publicly. We will be sharing all of the collected data with the research community using the Databrary data library at the end of the grant period. Our analysis code is shared on GitHub, and we use free and open source software tools as much as possible.
