--Have recently learned of this phenom. Can someone describe a method one relatively unversed in electronics might use to measure change in capacitance? Not necessary to have the cap in the circuit when measuring..

use a meter with a cap function on it., subject it to freezing spray and then with a hair dryer. log down the change in value.
The high-K ceramic types have both effects. Electrolytic caps can also have a slow loss of capacitance over time, as the electrolyte escapes.
Here is a good tutorial on the many differences of capacitor types:
