Coding
The general procedure for coding data in the lab is the same for all experiments, regardless of the coding method the study requires.

Getting started

To get started, open the coding app on our lab's database website.

Select experiment

From the coding app, select an experiment to code. The numbers indicate runs that need coding (big) and runs that need a second coder (small).

Select a run

After you select an experiment, you'll select a specific run to code from a few options:
  • in progress - shows the run you left off on
  • needs coding - shows a random sample of 5 runs that need coding
Note that you won't be able to select any runs in the new coding section until you've finished coding your run in progress.

Coding protocol

When you select a run, you'll be taken to the coding protocol: a 3 step process that is the same for all experiments in the lab.

1 Create coding sheet

In step 1, you'll click on the link to create a coding sheet for run. The coding app using information from the run (like the participant's data) to generate a unique .csv file for you to fill out as you code the data.

2 Code the data

In step 2, you'll use the coding sheet from step 1 and the study-specific instructions to code the data. If there are video or audio recordings associated with the run, they will appear here. For some runs — usually Lookit — you'll need to take an extra step and import the recordings first.

3 Upload coded data

In step 3 — the last step — you'll upload your coded data. Here, you'll be asked for three pieces of information:
  • Outcome - select the outcome of coding this run
    • complete - you completed the coding
    • partial you coded part of the run (usually because some videos/data were missing)
    • impossible you could not code the run (usually because all videos/data were missing).
  • Notes - Leave additional notes for the study team about the run.
  • Coding sheet - Upload your completed coding sheet. The app will check to make sure you uploaded the sheet for the correct run (file names should match). Once you select a file, you can use the view uploaded data link to see that it matches your coding sheet.
Click submit to finish coding this run!

Import recordings

For some experiments — usually Lookit studies — you'll need to import any recordings before you can view them in the coding app. If this is the case, the step 2 screen will show two additional things:
  • Lookit response UUID - you'll use this to retrieve the videos for this run from the lookit website.
  • Import recordings - a button that allows you to upload videos to our secure cloud storage bucket.

From Toto

You need to be on Toto to do this because you don't want to download participant videos onto your personal computer.
