Late maturation of semantic control promotes conceptual development

Late development of semantic control in the prefrontal cortex enhances conceptual learning, with simulations showing faster acquisition when control matures after initial knowledge.

• Why it matters: Understanding how delayed maturation of control processes influences learning can shed light on developmental advantages and inform educational strategies, addressing gaps in knowledge about cognitive development.
• What they did: A computational model was used to simulate the effects of late maturation of semantic control and connectivity on concept acquisition, supported by a meta-analysis of children aged 3 to 6 performing triadic matching tasks.
• The result: Findings indicate that delayed semantic control accelerates learning without harming representations, suggesting that protracted PFC development benefits conceptual development during early childhood.
