Why cramming for an exam doesn’t work
“Based on our data, it seems like synapses that have recently been strengthened are peculiarly vulnerable — more stimulation can actually wipe out the effects of learning.
“Psychologists know that for long-lasting memory, spaced training — like studying for your classes after every lecture, all semester long — is superior to cramming all night before the exam,” Barth said. “This study shows why. Right after plasticity, synapses are almost fragile — more training during this labile phases is actually counterproductive.”
