Behavioral Classes

Class column (e.g. eye movement) without any special characteristics, to log Observation Codes.

Numeric Classes
!Class name

Class column named with a leading exclamation mark (e.g. !Eye-blinks). This way, INTERACT presumes that such a Class contains numerical information that e.g. will be summarized in statistics and graphically represented in the Time Line Chart.
Use numeric Classes if you want to count any number of occurrence of a certain fact (e.g. the number of eye-blinks of an observed person). This kind of Class behaves completely different from ‘behavioral' Classes in various statistics and enables you to do specific numeric analysis.
IMPORTANT: only use numbers as Observation Codes in numerical Classes! (e.g. number of objects/actions  counted)

Rating Classes

Class_NUM

Class columns named with '_Num' at the end of its name (e.g. Emotion_Num) can be analyzed with the command Additional - Extensions - Functions >Numerical Scale Statistics. with the . INTERACT offers a special analysis report for the values present in such a Class.

IMPORTANT: use only numbers as Observation Codes in those Classes! (e.g. scale 0-5 to describe an emotional state.)

Comment Classes

(Class name)

Class column name in brackets (e.g. "(persons in room)") to collect additional information, which might be interesting to search for or does have a documentary function,  but should not be included in statistical calculations. This type of Class will not be taken into account in the various statistical operations nor will its Codes be included in the Code Archive.

TIP: Do not use those Classes to collect larger textual entries. It is better to place those comments in the transcript field.

Invisible Classes

?Class name

If you enter a questions mark ? infront of a Class column name, all logged Codes in that column are hidden. Removing the ? shows the Codes again.
