Description

Hunt recommends sequential ordinal scales, inspired by Piaget's observations, as an alternative to norm-referenced mental-age and IQ metrics. Because such scales "mak[e] no assumption of automatic developmental progress with time," they disentangle psychological development from age, permitting age to be used as a dependent variable for assessing the development-fostering impact of environmental conditions. Hunt presents them as tools for investigating plasticity, the experiential bases of each developmental line, and cognitive-affective relations.

Design Implications

Context

Requirements

  • Behavioral landmarks arranged in a hypothetically sequential order that observers can agree on, with cross-sectional evidence of ordinality

Constraints

  • Hunt notes the scales' present form rests on only cross-sectional data, and whether the observed sequences hold across diverse rearing conditions remains to be seen

Target Learners

  • infants and very young children

Target Learning Objectives

  • sensorimotor and cognitive development, including object permanence, means-end behavior, imitation, causality, and spatial relations
