When Naïve Pedagogy Breaks Down: Adults Rationally Decide How to Teach, but Misrepresent Learners’ Beliefs

Abstract From early in childhood, humans exhibit sophisticated intuitions about how to share knowledge efficiently in simple controlled studies. Yet, untrained adults often fail to teach effectively in real-world situations. Here, we explored what causes adults to struggle in informal pedagogical exchanges.

Elevated platelet count hampers brain-cognitive link in mild cognitive impairment patients

Imagine you have a limited amount of money to spend on shopping, but your credit card keeps getting declined. Similarly, in patients with mild cognitive impairment (MCI), an elevated platelet count inhibits the connection between brain functional changes and cognitive function. A recent study used resting-state functional magnetic resonance imaging (fMRI) to explore how blood […]
