It would be helpful if you define with what (thing/person/enviornment, etc.) are these interactions happening? One way to observe interactions is to adopt video ethnography.

Dear Muhammad

I think it is best to narrow down what exactly you wish to study before doing a literature search, which though always useful, can take a lot of time. You mention "effects", which suggest a statistical approach, in which case you could Google terms such as "effects on interaction between pupils in schools"; teacher-pupil interaction, effects, etc. Best wishes Paul

If you are teaching or do your research in math, like I do, this reference may be of help to you to improve your students output in math.
