When we are talking about pragmatics, we just have a communication regardless dealing with interaction. My question is on the difference between "interaction" and "communication". For example, in case of integrative and pragmatics tests, "communication" has an important role while on functional tests the most important thing is having "interaction". Can you please help me out?
As I read in "testing language skills from theory to practice" by Farhady, pragmatics and integrative tests have both communication but lack of interaction. Reading about Functional testing, I see an "interaction" term. Actually he mentions that both pragmatics and integrative tests have just communation, on the other hand, "functional testing" has both interaction and communication.
The difference between the two is simple: communication is when one person informs another: interaction needs the person to respond. I would suggest that "Hi there" is possibly too informal a start.
I don't really understand the initial question. I don't know what 'integrative' and 'functional' tests are. For me, though, communication is defined as follows:
Information exists encoded at one place;
It is decoded;
It is then transmitted from the place it exists;
It is received at another place;
The information is then encoded at the place it was received.
In this way, communication doesn't really exist without interaction. I doubt interaction exists without communication - there is always some sort of contingency: one person does something that leads to another person doing something as a result. That is what interaction is. That is what communication is.
Yes, you are right; however, in that book I refer to before on pragmatics, integrative and functional tests, the author mentioned that the two first examples coud have communicated without having interaction so the later, funtional tests, came and played roles of both communication and interaction at that time. Funtional tests have done very rarely and they spend most time as well as cost to make a real situation for giving a test.
