Press the Start observation

button to start observing. Step 2 - Acquire your data Score the observation by pressing the keys of your keyboard. In the Codes window

you can see which of the elements you should score next, Subject, Behavior or

Modifier. Once you scored the Subject, the tab Behaviors opens. Similarly, once you scored behaviors that have modifiers attached to it, the tab Modifiers opens. You can view your scored data in a Time-Event plot similar to the plot in the Visualization part of the software. The plot "grows" while you are scoring, giving you a good overview of the scored data. To stop the observation, click the Stop observation button.

Free text

For each event line you can enter a comment of up to 1024 characters. For example, to transcribe speech from an audio file. Choose View Settings > Comment. Type or paste the text in the Comment cell in the event log or in the Comment window. Note that free text is not analyzed, however it can be visualized. Step 2 - Acquire your data

Control video playback

To play the video at lower or higher speed, click the Speed down or Speed up button. Press the space bar on your keyboard to pause and play the video. If you missed an event in the video, click the Quick Review button. The video then jumps back a few seconds and plays the event you missed at a lower speed. Click the Quick Review button multiple times to jump back more in time To review a video fragment multiple times, click the Loop button and set the flags that appear to the start and end of the fragment.

Code in runs

If you have a large Coding Scheme, you will probably not be able to code everything at once. It is common that you play the video once for every subject-behavior group combination. For example, score the behavior group Playing for the subject Child in run 1, Verbal behavior for Child in run 2 and Verbal behavior for Parent in run 3. After you finished with one run, do not stop the observation, but go back to the start of your observation. To do so, click the first row,

You can also use keyboard shortcuts to control video playback. See Keyboard

shortcuts in The Observer XT Help for the options. Step 2 - Acquire your data that has time 0.00, and click the play button on the Playback Control window. You can now score the next subject - behavior group combination. If you stopped the observation after a run, you have to click the Start-observation button again to continue with the next run.

Code in runs with multiple subjects

If you defined multiple subjects in the Coding Scheme, use the Auto-record Subject feature. With this feature the subject scored in the last event is automatically scored in the next event. Run through the video one or more times for one subject. Then run through the video for the next subject. Once you pressed the key code for that subject, it is automatically scored for the next events. To switch on Auto-record Subject, choose Setup > Project Settings > Scoring Options. Select Auto-record Subject. Step 3 - Analyze your data
