What Does Test Anxiety Really Signal?

Test anxiety afflicts nearly half of all students, yet Peter Brown, Henry Roediger, and Mark McDaniel reveal a counterintuitive truth: anxiety explains only three to seven percent of exam score variance.

Self-testing builds stress-resistant recall that cortisol cannot crack.
