A Metatheory for Cognitive Development (or "Piaget is Dead" Revisited)

Area of Science:

• Developmental Psychology
• Cognitive Development
• Evolutionary Developmental Psychology
• Developmental Biology

Background:

• The field of cognitive development lacked a unifying metatheory after the decline of Piaget's theory.
• Developmental biology, especially evolutionary theory, was proposed as a potential unifying framework in 1997.
• Over the past two decades, biological perspectives have gained prominence in cognitive development research.

Purpose of the Study:

• To examine the growing influence of biology on cognitive development research over the last 20 years.
• To explore the emergence and impact of evolutionary developmental psychology.
• To assess the role of proximal and distal biological causation in the field.

Main Methods:

• Review of research trends and theoretical shifts in cognitive development.
• Analysis of the integration of biological concepts, including evolutionary theory.
• Examination of case studies highlighting biological causation in development.

Main Results:

• Significant increase in the emphasis on biological factors in cognitive development research.
• Establishment and growth of evolutionary developmental psychology as a subfield.
• Demonstrated influence of both proximal (immediate) and distal (evolutionary) biological factors.

Conclusions:

• Developmental biology is poised to become increasingly influential in cognitive development.
• Evolutionary theory is emerging as a strong candidate for a general metatheory in developmental psychology.
• The integration of biology offers a path toward unifying disparate areas of cognitive development research.
