I've generally heard the two concepts discussed as abstraction vs generalization.

Abstraction hides unnecessary detail. Generalization finds/surfaces commonality among items.

Creating a procedure/method is a form of abstraction. Allowing it to accept parameters is a form of generalization (by allowing it to be used for a number of similar inputs).

Simply creating an integer data type is a very simple form of generalization. Allowing operations to work against generically against any integer.
