This study examines cognitive reserve theory by investigating the relationship between education and cognitive performance across developed and developing countries. Using numeracy and verbal fluency measures, it finds that higher education consistently improves cognition. However, cognitive performance is largely similar across countries once education level is considered, challenging assumptions about educational quality differences.

Large unstructured lecture breaks often disrupt learning, causing distraction and poor recall. This research tests structured “consolidation pauses” where students spend 2–5 minutes reviewing material before break. Results show improved retention, better peer relationships, and up to a full letter-grade boost, demonstrating that small instructional changes markedly improve learning outcomes.

This research examines the cultural practice of burying umbilical cords in Nigeria’s Middle Belt, a region shaped by conflict and ecological crisis. Unlike Western views that treat the cord as waste, local traditions see land as a living repository of memory and identity, reframing human–land relationships as reciprocal and deeply interconnected.

This research compares three experimental models of anxiety — threat of shock, CO₂-induced panic, and speech-induced social anxiety — to reveal how each affects cognition. Findings show distinct patterns in attention, memory, and loss aversion, offering insights that could improve and better tailor treatments for anxiety disorders.
