Using Lexical coding
The coding mode Lexical coding (post-hoc) was designed to create an exhaustive and exclusive stream of Events.
▪For details on this coding mode, read the section Coding Mode: Lexical (post-hoc).
Using Mutually Exclusive Codes
With valid exclusion lists, as described in Define Mutually Exclusive Codes, you only need to log the START of each behavior:
▪To activate the observation mode, click 
.
▪Click a ‘Gaze’ Code that corresponds with the situation at the start of your session (for example, Monitor) to log the start of the gaze being on the monitor.
▪Click an ‘Attention’ Code that describes the start of the session.
▪To start the video, click Play 
.
▪Click the Code Moderator, the moment the gaze shifts from the monitor to the moderator.
▪Click the Code Room, if the gaze wavers through the room, etc.
▪Click another ‘Attention’ code the moment you notice a change in the attention
Each Code automatically closes the Event of its predecessor, from the same Exclusion list.
IMPORTANT: Sequential Events in INTERACT begin and end at different frames!
For truly successive Events each successive start time = previous Offset + 1.
Note: For a continuous coding rhythm, you need a Code for every situation. This means that some additional Codes (like 'NILL' or 'neutral') that cover the uninteresting parts simplify and speed up the logging process. Because switching between logging only the start for most Events and then sometimes needing to code the end separately is confusing and therefore a source of error.
