Cognitive theory uses a hierarchical series of "schemes" to describe mental functioning. A scheme is an organized series of operations serving to regulate and structure experience and behavior. For example, Reciprocal Role Procedures (RRP's) are schemes governing a person's interactions with others, and they incorporate the capacity to predict and adapt to the reciprocating acts of others. The language, terminology, and formulations of this cognitive theory may be used to describe theories and concepts which originated in psychoanalysis, such as object relations theory, resistance, transference, splitting, and projection. Ryle gives examples using the concept of RRP's to explain these psychoanalytic concepts. This approach is said to 1) overcome the confusing, isolated, idiosyncratic, inconsistent, arcane, metaphorical language of psychoanalysis and 2) state the clinical concepts of psychoanalysis in a clear, scientific language for the purpose of science.
