How to read this

Every construct on the map is compared with every other by the meaning of its definitions, and the closest one is surfaced here. The nearest construct to stage is development.

Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

Geology and stratigraphy

A body of rock formed during an age

A body of rock laid down during one age of Earth's history, the basic working unit of the chronostratigraphic scale that geologists use to line up rocks of the same age around the world. Alcide d'Orbigny introduced the idea of the stage, the French étage, in his 1849 to 1852 Cours élémentaire de paléontologie et de géologie stratigraphiques, naming units such as the Toarcian and the Bajocian after localities; Gradstein and Ogg's 2020 account of the chronostratigraphic scale gives the modern definitions and boundaries. The referent is the actual rock formed in a span of time, not the span itself, and it is distinct from a stage for performance, a rocket section, or a step in cognitive growth.[1][2]

Unit
One body of rock representing a single age, bounded by defined lower and upper limits
Recovery means
Not applicable
Measured by
Fixed by a defined boundary point in a reference rock section and correlated by fossils and isotope dating

Developmental psychology

a qualitatively distinct period in one ordered series of thinking stages that every child passes through.

A qualitatively distinct period in the growth of thinking, one of an ordered series that every child passes through in the same order, each marked by a characteristic way of reasoning. Jean Piaget's 1936 La naissance de l'intelligence chez l'enfant traced the earliest of these stages, in which intelligence grows out of sensing and moving; David Feldman's 2004 reassessment revisits how sharp and how universal those stages really are. The referent is a phase of a person's cognitive development, measured by what a child can and cannot yet do, and it is unrelated to a platform for actors, a rocket module, or a layer of rock.[3][4]

Unit
One developmental period, defined by the reasoning a child in it can perform
Recovery means
Not applicable
Measured by
Assessed by standardised reasoning and conservation tasks and by observation of how children solve problems
