Non-substantive response

A nonsubstantive segment is defined as a continuer, a repetition, an agreement, or off-task remarks . For example, to the Tutor explanation shown below the Tutee has responded with “alright,” which would be coded as a nonsubstantive response:

Example (1):

 -Tutor: See this equation is true for constant acceleration.
       Now the acceleration is constant here.
       Forces are not changing on the weight so the acceleration is constant.
 -Tutee: alright.

Example (2):

-Explainer: ["So essentially, the way I'd apply negative harmony", 'would be this idea of polarity, you know,', 'between the overtone series and the undertone series,', 'or you know, the one side and the other side.', 'The perfect and the play goal.', 'The feeling of a minor perfect--', '(keyboard music)', "Resolving, it's so moving, you know?", "And it's a good alternative to something like,", '(keyboard music)']
-Explainee: ["It's funny, you know, you doing that", 'makes something in a major key', 'sound like kind of a wistful sad song.']
-Explainer: [Right.]
-Explainee: ['You know, you changed the feeling of it,', 'what otherwise would, you know, if you were to tell a kid', 'that this is a major song, we should be happy.']
-Explainer: ['Exactly, yeah.', 'No, for sure.', 'And, you know, F major can be something you arrive in from,', 'if you arrive in F major from D flat,', "then it's like the sun's come up."]
-Explainee: [Right.] ----> Non-substantive response
-Explainer: ['But if you arrive in F major from A major,', "then it's like the sun's gone in."]
-Explainee: [Interesting.] ----> Non-substantive response
-Explainer: ["So, there's a lot about context, I think.", "Once you have a language, it's about using it", 'and applying it in those emotional ways.', "I think that's what makes the difference."]
-Explainee: [All right.] ----> Non-substantive response
