To pass the time one day, Keisha multiplies 2 by 2 by 2 by 2 ... and so on, on her calculator. She observes that the products increase in size more dramatically with each calculation. A few weeks later, when her math teacher explains what it means for something to increase exponentially, Keisha realizes that she has already discovered this idea on her own, and she remembers it better as a result. Which one of the following concepts best characterizes Keisha's enhanced understanding of an exponential increase?
A) The generation effect

The generation effect refers to the fact that we are more likely to remember information that we have generated ourselves, as opposed to information that is simply presented to us. Keisha's act of multiplying 2 by 2 repeatedly on her calculator is an example of self-generated information, which she remembered weeks later when learning about exponential growth.
