One might imagine that if energy generation by nuclear fusion were to increase in a star, this would heat the gas, which would i
n turn increase the rate of nuclear fusion, and so forth in a runaway cycle of increasing temperature. What process acts in a normal main-sequence star to prevent this behavior?
Increased energy generation will cause a temperature increase which will eventually cause expansion and hence cooling of the gas. This slows down the nuclear fusion.
The self-reference effect is the tendency an individual to have better memory for information that relates to oneself than information that is not personally relevant.
