120 students participated in this experiment. The experimental results show that the subjects who have learned a series of words and images through retrieval practice have no obvious memory damage after experiencing important pressure. However, participants who remember by reading materials repeatedly can only remember less, especially after stress.
Ayabe Thomas, an associate professor of psychology at Tufts University in Massachusetts, said: "Stress has a negative effect on memory. Usually, people under pressure don't take the initiative to extract information from their memories. This new study shows that certain learning methods can offset this influence. After directly testing the memory state, the influence of stress can be offset. When subjects learn new materials through exams, a very effective learning method, their memory will not be negatively affected by stress. "
The researchers asked participants to learn a set of 30 words and 30 pictures. These contents are entered into the computer and displayed every few seconds. In order to imitate note-taking, participants are given 10 seconds, and they can see the content immediately after entering keywords on the computer. A group of subjects used the method of retrieval practice, that is, the time test method, and let them recall as much content as possible freely through the simulation test. The other group adopts the way of repeated review, that is, the conventional way. These participants watched the contents of the computer repeatedly, and the participants were given multiple time periods for research.
After a 24-hour break, some members of each group were placed in a tense scene. These participants must give impromptu speeches or solve complex math problems in front of two judges, three companions and a camera. Participants need to test what they learned the day before under pressure and after pressure to test the impact on memory. Other participants who are not under pressure also take the test. Under pressure, subjects who study through retrieval practice can remember 1 1 in 30 words and images, while students who are not under pressure can remember10; In the other group, participants who studied through repeated revisions could remember an average of 7 items, while participants who had no pressure could remember 9 items.
The researchers said that even if the previous research showed: "Of course, our research can't draw the conclusion that retrieval practice under pressure affects memory, but it is still very suitable for some students who still need to remember complex information under high pressure, especially educators. Students are under great test pressure, so they hope to add more mock exams in their usual teaching. Our research also proves that the length of study time and the content of study are not the most important, but the most important thing is the learning method. "
Examination is one of the best learning strategies, but they are still surprised that it is still so effective under pressure, just as stress has no effect on memory. Learning through exams has a great influence on the maintenance of long-term memory. (Science fiction Galaxy Constantine/Wen)
