I do not distinguish between positive and negative feedback. Positive means that I do follow in the correct direction and I should keep going that theme. Negative is an indicator that I should make adjustments to keep myself on the path.
To illustrate it. I obtain negative feedback about my essay. My tutor provides me with about 40 comments and annotations about the quality of my work. I can perceive this feedback as critic and as a matter of fact, it is. But it is also perfect feedback to evaluate and improve my writing skills. My tutor provides me with massive feedback. My essay weight 2000 words and I have got 1800 words of feedback. Should I treat it as something wrong? No. I treat it as a post showing me how poor my writing skill is. It was a perfect opportunity to improve what of course I have done.
Positive feedback. Is something that feeds my internal monster with serotonin. On the other hand, serotonin does not provide neuroplasticity. It congruent feeling of relaxation and sedation. To be honest, even I got positive regards I always ask what I can do better. It is to account for the adrenaline/norepinephrine substance required to start the learning process. To learn something we must fail. To summarise something that the general public calls; negative feedback, have me positive outcome. Furthermore, perception always depends on our internal camera settings.
