A new study conducted by researchers from Tufts University in the US has said that learning by taking practice tests can protect memory against the negative effects of stress.
Speaking about this, the researchers said, Typically, people under stress are less effective at retrieving information from memory. We now show for the first time that the right learning strategy, in this case retrieval practice or taking practice tests, results in such strong memory representations that even under high levels of stress, subjects are still able to access their memories. Our results suggest that it is not necessarily a matter of how much or how long someone studies, but how they study.
Results of the study showed that participants who learned through study practice remembered fewer words overall, with an average of 7 items for stressed individuals and an average of a little under 9 items for those who were not stressed. The study appears in the journal Science.
