Download data: Events structure

The events structure is a list of timed events during a task. It contains events such as a participant interacting with a stimulus, or resizing the screen.

Compatible file types

Events structure data is currently only available in the .log file type. Read more about the log file and how to import it.

Structure

Each event is represented by one row. There are three columns:

• time The time of the event in milliseconds elapsed since January 1, 1970 00:00 UTC
• name The name of the event. See below for examples.
• variables a key/value map with variables, such as the stimulus affected by the user action.
