ABSTRACT
Stimulus array invariants are information for ecological perception (Gibson, 1966). Michaels and Carello (1981) assert two classes of invariants: “… Structural invariants … specify the object or collection participating in the event … A transformational invariant… specifies the change occurring in or to the object” (p. 26). Some patterns of change, however, are common across events involving different structural and different transformational invariants. Meta-invariant describes a pattern of change common to disparate events, independent of either structural or transformational invariants.
