- Piaget's theory of cognitive development (history · last edit · rewrite) from several sources. I ran Earwig checks on a few different diffs (see here, here, here) and there are copyright problems dating back to at least 2019. There are many different references that are problematic, and I'm not sure if there are circular reference problems. A more in-depth investigation and clean-up is needed, probably with extensive revdel. Aspening (talk) 20:05, 29 January 2021 (UTC)
