Below is the project-wide workflow. The PLAY team will provide training, quality assurance, transcription, reliability coding, and collating data for the final PLAY database. The collaborating sites will perform data collection and various levels of data coding.
The collaborating sites in PLAY perform a variety of roles (see [people](people.html) for details). Each site that performs a **collecting** role is pre-assigned to complete all of the collecting functions (see in blue below). This page contains detailed help for the recruitment of participants.

PLAY aims to set new standards for conducting open, transparent, and reproducible behavioral science by i) publishing the protocol, and ii) making extensive use of video exemplars to demonstrate phenomena and illustrate behavioral codes. For confidentiality reasons, access to video exemplars is restricted to researchers with authorized access to [Databrary](http://databrary.org). To register for access, visit <http://databrary.org/register>.

PLAY will produce a widely varied and rich set of data, most of which will be openly shared with the research community at the end of the five-year NIH grant period in late 2023. Infants' natural play in the home is characterized by tremendous variability including variations in: geographic location, climate, SES, maternal/paternal employment, childcare experiences, infants’ and mothers’ ages, language environment, physical layout and characteristics of the home, availability of media, toys for play, and so on. Researchers will be able to explore the effects of any/all such factors.
