The functional and developmental organization of cognitive developmental sequences.

Area of Science:

• Cognitive Psychology
• Developmental Psychology
• Educational Psychology

Background:

• Adolescent cognitive development involves complex reasoning skills.
• Assessing the validity and reliability of reasoning tests is crucial for developmental research.
• Understanding the organization of reasoning domains informs educational and psychological theories.

Purpose of the Study:

• To examine the organization and development of five reasoning domains (categorical, quantitative, spatial, causal, propositional) in adolescents.
• To establish the construct validity of a test measuring reasoning development from early adolescence to early adulthood.
• To identify developmental stages within reasoning abilities.

Main Methods:

• Confirmatory factor analysis to validate the five reasoning domains and identify a common factor.
• Rasch modeling to scale items, assess reliability, and test measurement invariance across demographic groups.
• Cluster analysis and the saltus model to uncover developmental stage-like levels of difficulty.

Main Results:

• The confirmatory factor analysis validated the five domains of reasoning and a significant common factor.
• The Rasch model demonstrated high reliability and measurement invariance of the test across gender and school type.
• Five distinct developmental stage-like levels of reasoning difficulty were identified.

Conclusions:

• The developed test effectively measures five domains of reasoning and their developmental progression.
• The findings support a multi-domain model of reasoning with an underlying general factor.
• The identified developmental levels offer insights into cognitive progression during adolescence and early adulthood.
