Prefrontal Analysis (PFA) is a type of active constructive imagination that allows humans to mentally reduce an object into parts. For example, humans can recall a kettle and then mentally break a handle. The imaginary kettle with the broken handle, a horse without the tail, or a cow without the ear are novel objects since they were never before observed physically. The process of generating these objects in the mind is the process of image decomposition or analysis, as opposed to Prefrontal Synthesis that involves combining two or more objects together.
