Refers to the over-reaction to symptoms exhibited by people who are suffering a panic attack (ie; thinking they're having a heart attack) and the subsequent increase in anxiety levels.
Note: Positive feedback is actually an electrical term meaning "feedback that results in the amplification or growth of the output signal." In terms of anxiety, this means the feedback (the symptoms) amplifies (worrying unnecessarily about symptoms) the output signal (increased anxiety).

How is a positive feedback stopped?
The positive feedback loop is terminated by the end of childbirth...
What is a vicious cycle?
positive feedback loop
What is sometimes called a''vicious cycle''?
positive feedback loop
What are four conditions in the cell that must be kept in the homeostatic balance?
- temperature - negative feedback loop - positive feedback loop - water balance
What happens during positive feedback loop?
During a positive feedback loop, the output of a process amplifies or reinforces the initial stimulus, leading to an increase in the response. This can result in rapid changes or escalation of a particular process. Positive feedback loops are important in biological systems for processes that require quick and decisive responses.
What makes closed-loop op amp unstable?
A: It does not. The loop becomes unstable ONLY if there is positive feedback either voltage or phase. For a close loop to be stable negative feedback is required.
Is the war on drugs a positive feedback loop?
Yes. Have fun proving it.
How might the emergence of a positive feedback loop affect a system in homeostasis?
A positive feedback loop can disrupt a system in homeostasis by amplifying an initial change away from the set point, leading to an escalation of the deviation. This can push the system further out of balance and prevent it from returning to its original state. In extreme cases, a positive feedback loop can result in system failure or collapse.
What are the component of oscillator?
It can contain active and passive components with a positive feedback loop.
Ozone layer depletion is an example of what kind of feedback loop?
Ozone layer depletion is an example of a positive feedback loop, where the thinning of the ozone layer allows more harmful UV radiation to reach the Earth's surface, leading to further ozone depletion.
Is the ADH feedback loop an example of positive or negative feedback?
The ADH feedback loop is an example of a negative feedback loop. Negative feedback loops occur when the output of a system acts to oppose the changes to the input of the system. This is the case with ADH because when there is not enough water, the hypothalamus and pituitary gland work to release ADH so that the body can retain more water.
A self-amplifying chain of physiological events is called?
Positive feedback loop. This is a process in which a change in a physiological parameter triggers responses that amplify the initial change, leading to a continuous increase in the parameter until a specific endpoint is reached.
