Children's Social Understanding Scale
Datavyu (http://datavyu.org) is a complete software package for visualizing and coding behavioral observations from video data sources, developed by and for developmental scientists. Datavyu supports multiple data streams—video, audio, physiology, motion tracking, eye tracking—and links them together with a flexible, extensible coding spreadsheet that enables time-locked coding and visualization. Keyboard shortcuts and user-defined scripts let users navigate quickly and iteratively through data streams, adding comments, codes, and interpretations.
Datavyu is free, and open source, runs under both Windows and Mac OS, and there is an online user guide (http://datavyu.org/user-guide/) and support forum (https://github.com/databrary/datavyu/issues).
Datavyu is part of the Databrary (http://databrary.org) project, led by Karen Adolph (NYU) and Rick Gilmore (Penn State) and supported by the U.S. National Science Foundation (NSF) under BCS-1238599 and the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) under U01-HD-076595.

Using Numerus, you can make and export arrays of objects (rectangles, squares, triangles, and circles) in which variables such as area, perimeter, density, and item size are systematically manipulated by the user. You can also obtain and export the arrays’ specific stimuli dimensions in a .csv file.
To use Numerus, you must be running a Macintosh OS, have access to a web browser, and have the free Python programming language downloaded onto your computer (find it at python.org). No programming experience is needed to run Numerus. You can find instructions for installing and running Numerus inside the Numerusapp folder (Numerusapp —> Installation.pdf: SEE NOTE BELOW FOR UPDATES TO THESE INSTRUCTIONS), and instructions for creating stimuli in the Numerus Introduction video, also in the Numerusapp folder (Numerusapp –> bcdc –> numerus –> static –> video –> Numerus.Introduction.mv4).
**Important Note** Recent updates to Mac OS security have resulted in the program needing to be launched after download in a slightly different way than indicated in the instructions. To launch Numerus, instead of clicking on Startnumerus, you must right click on launch.py and open with the Python launcher manually. You can then select numerus.webloc to start the program.
Thank you for your interest, and we hope you find this program useful.
