Quizplus · Accepted Answer

Reversibility is the ability to mentally reverse a sequence of steps, which is exactly what Ryan is doing. Conservation refers to the understanding that physical quantities remain the same even if their appearance changes, decentration involves the ability to focus on multiple aspects of a situation, and seriation involves the ability to arrange objects in a logical order. None of these concepts are directly related to Ryan's ability to mentally reverse his steps.
