You can define a behavior state that includes two or more of the behaviors detected automatically. For example, to calculate the overall frequency of Rearing = Rearing supported + Rearing unsupported.
How to specify Merged behavior
1.Click the Add button next to Merged Behavior.
2.Under Select behaviors to merge, select which behaviors you would like to merge for analysis.
For example, select Rearing supported and Rearing unsupported to analyze the total occurrences of Rearing.
3.Under Behavior probability threshold, select:
▪Default: Statistics will be calculated by using all samples scored as that behavior (no filtering based on the state’s probability).
▪Probability greater than: Statistics will be calculated by using only the samples for which the probability of one of the merged behaviors is higher than a specific value. Select this value from the list. See a note below.
4.Under Behavior duration threshold, next to Exclude behavior instances shorter than, enter the minimal duration of the merged behavior to be considered for analysis.
note The threshold is applied to the merged behavior, not the instances of single behaviors. For example, two instances of behaviors Rearing unsupported and Rearing supported follow each other in the time line. The first lasts one second, the other two seconds. When you merge the two behaviors and select a duration threshold of 3 seconds, the two behaviors are considered for analysis.
5.Complete the procedure to add the variable. See Calculate statistics: procedure.
Note
The Frequency of Merged behavior may not always be equal to the sum of the frequencies of the single behaviors. This can happen, for example, when an instance of Rearing supported is immediately followed by an instance of Rearing unsupported. Then the frequency of Merged behavior is 1, not 2.
