Positive Feedback

Positive Feedback can be generated in answer to the previous utterance. It could be a statement or a short answer. For instance, the speaker confirms the previous utterance by using remarks such as “that’s true”, ‘absolutely”, “exactly”, etc., or the speaker might respond by generating a simple positive word/phrase such as “yes”, “yes, I do”.

Example(1):
-Explainee: ['Well, dogs are very playful, I think, more than cats.', 'Cats lick themselves more than dogs, I think.']
-Explainer: [That's true., 'Do you think, if we look at these pictures,', 'do you think maybe we could say,', 'Well, they both have pointy ears,', 'but the dogs have a different kind of body', 'and the cats like to stand up a little different.?', 'Do you think that makes sense?']--> Positive Feedback

Example(2):
-Explainer: ['And so we get the power with a lot less energy', "'cause its power is energy per unit time.", "So we aren't depositing much energy in comparison.", "Can I just ask, 'cause you are using", 'the thermal process of it heating up,', 'but have you ever had the opportunity', 'to use laser tweezers?'] 
-Explainee: [I have, yeah., 'We use optical tweezers to trap particles in solution.']--> Positive Feedback

Example(3):
-Explainer: ['So it is amazing, the parallels.', 'And optics is used everywhere.', "We're gonna possibly take over from CERN,", "we'll just do high energy physics with lasers,", "we're looking at gravity waves with lasers,", 'we wanna do black holes with lasers,', 'we wanna machine with lasers,', 'we wanna do medicine with lasers.', "It's everywhere.", 'And now, with the Nobel prize, people are hearing', 'more about it so they know lasers are everywhere.'] 
-Explainee: [I couldn't agree with you more]--> Positive Feedback
