Can somebody explain Positive Feedback to me?

Question

and PLEASE don't just give me a link to wikepedia or copy and paste something from them!

Examples are REALLY needed!

THANKS!

Answer 1

okay..let's try again..LOL

In positive feedback (physiology) an event A leads to response B which leads to re-initiation and intensification of the event A which leads to a stronger response B…and so on, until a treshold is reached or the final goal is accomplished, when everything goes abruptly back to normal.

A good example is: The blood clotting mechanism is a cascade of biochemical reactions that operates acording to this principle. An injury stimulates production of a molecule that triggers production of another molecule which triggers production of another molecule as well as production of more of the first molecule, and so on, until the injury has completely closed.

Childbirth is another example of the positive feedback loop. When the baby is ready to go out (and there’s no stopping it at this point!), it releases a hormone that triggers the first contraction of the uterus. The contraction of the uterus pushes the baby out a little. That movement of the baby stretches the wall of the uterus. The wall of the uterus contains stretch receptors which send signals to the brain. In response to the signal, the brain (actually the posterior portion of the pituitary gland, which is an outgrowth of the brain) releases hormone oxytocin. Oxytocin gets into the bloodstream and reaches the uterus triggering the next contraction which, in turn, moves the baby which further stretches the wall of the uterus, which results in more release of oxytocin…and so on, until the baby is expelled, when everything returns to normal.

that help more?  ;)

Answer 2

Explaining the things you thought were good about someone's writing, performance, etc, so they can continue doing those things in the future. This way they don't feel bad about themselves and they still learn something about what good things to emphasize in their work. ie: if someone wrote a poem and you told them you really liked their use of metaphors, they would be aware that it's one of their strengths.

Answer 3

do you need to know what positive feedback means?
