Subclaims¶

q2 i? Aerobic fitness and diet affect hippocampal volume and predict individual differences in episodic memory, and these health-factor effects may be magnified during childhood when hippocampal structure and function are still developing. → Fandakova 2016

Evidence¶

Fandakova 2016¶

Fandakova, Yana; Bunge, Silvia A. (2016). What Connections Can We Draw Between Research on Long-Term Memory and Student Learning? Mind, Brain and Education, 10(3). https://doi.org/10.1111/mbe.12123

q2 · i? · review · r2

Review article (Hassevoort, Khan, Hillman, & Cohen) on lifestyle factors, hippocampal health, memory, and academic performance, as summarized in this introduction. The review attributes memory and academic performance differences at least in part to effects on hippocampal structure and function.

"The authors review evidence that aerobic fitness and diet affect hippocampal volume and predict individual differencesinepisodicmemory."

Discussion¶

Learner Variables¶

• Physical Well-Being — predictor: learners who differ on it differ in outcomes

Related Claims¶

• Exercise Increases Hippocampal Volume — related
• Hippocampal volume relates to episodic memory differently across development: adults show head/body associations, children show tail associations — related
• Hippocampal microstructure continues maturing after early childhood: anterior hippocampus loses mass and posterior hippocampus gains mass from age 4 to 25 — related
• Physical well-being — exercise, sleep, and nutrition — impacts learning — a broader claim this one bears on
• The anterior hippocampus becomes functionally specialized for episodic memory around the transition to adolescence — related
• The authors propose aerobic fitness as a possible predictor of developmental cortical thinning and a pathway to enhanced cognition and scholastic performance — related
