I recently remembered this post about retrieval practice and stress<\/a>. I was talking to one of my students about retrieval practice and stress, and went back to the blog to help me remember some aspects of the research. Upon seeing the original publish date, June 25, 2020, I remembered how stressful that time was for so many of us, and the extra stressors that my family experienced that summer. (In fact, looking at that date, I know I must have written this a few months earlier and had it ready to go for the summer becuase I definitely wasn\u2019t writing at that time.)<\/p>\n

Things feel different now, and yet 2026 feels pretty stressful as well. I know I\u2019m not alone in this. In fact, I think my students might be more stressed now than they were six years ago! So, for this week\u2019s post, I\u2019m reposting this piece.<\/p>\n

Megan, circa 2015, stuck at an airport. I\u2019m definitely not in airports this spring, but this is reminiscent of how I feel some days in 2020!!<\/p>\n<\/figcaption><\/figure>\n

School can be stressful, and 2020 has been a particularly stressful year for many of us. So, for this week\u2019s blog, I thought I would write about retrieval practice and stress. Fortunately, I get to share some good news!\u00a0<\/p>\n

Prior research has shown that acute stress can hinder our ability to retrieve information. Acute stress is stress that comes from a specific event.<\/p>\n

(Note: Acute stress is different from chronic stress, where our exposure to stress hormones is repeated and relatively constant. For more information on acute and chronic stress, see <\/em>this page through the Centre for Studies on Human Stress<\/em><\/a>. I also really like this <\/em>3-minute video with Robert Sapolsky on psychology and stress<\/em><\/a>. And, if you really want to commit to learning more about stress and health, Robert Sapolsky has a book called <\/em>Why Zebras Don\u2019t Get Ulcers: Stress and Health<\/em><\/a>, and a <\/em>90-minute lecture on YouTube about the topic<\/em><\/a>. He is extremely knowledgeable, engaging, and funny!)<\/em><\/p>\n

Acute stress getting in the way of retrieving information can be pretty bad for student learning. If we are experiencing stress before an important test, either due to the test or because of something else, we might be less likely to be able to retrieve what we have learned thus decreasing our performance on the important test!\u00a0<\/p>\n

Fortunately, there is some evidence to suggest that retrieval practice might be able to protect against memory inhibition that we might experience while stressed (1)<\/em>. In a study published in Science<\/em><\/a>, a very high-profile peer-reviewed publication, Amy Smith and colleagues (2016) investigated retrieval practice and stress. They had four groups of participants:<\/p>\n

    \n
  1. \n

    retrieval practice plus not stressful activity<\/p>\n<\/li>\n

  2. \n

    retrieval practice plus a stressful activity<\/p>\n<\/li>\n

  3. \n

    restudying plus a not stressful activity<\/p>\n<\/li>\n

  4. \n

    restudying plus a stressful activity<\/p>\n<\/li>\n<\/ol>\n

    To start, they had all participants study nouns and images. While these are considered basic materials, they help the researchers determine cause and effect relationships in the lab to classroom model (2)<\/em>. Then, some of the participants engaged in retrieval practice where they recalled as many as they could remember across a couple of trials, while the other participants restudied the items across a couple of trials. (There was some nuance to the way they had participants study and either restudy or practice retrieval, but it is not central to the main point here.) After this learning phase, they left the lab.<\/p>\n

    Twenty-four hours later, everyone returned. The participants that were assigned to the stressful activity conditions were asked to give speeches and solve math problems in front of two judges and three of their peers. This sounds incredibly stressful to me, and a lot of other research confirms people find this stressful. Smith and colleagues took some physiological measures to confirm that the participants were stressed. The other participants just completed a simple not stressful activity instead. The participants\u2019 memory was tested immediately after the start of activities, and after 25 minutes.<\/p>\n

    Here are the main takeaways from the results:<\/p>\n

      \n
    1. \n

      Overall, retrieval practice led to greater performance than restudying.<\/p>\n<\/li>\n

    2. \n

      For the group that restudied, stress did reduce memory performance. The acute stress did not affect the participants\u2019 ability to retrieve what they learned instantaneously. However, within 25 minutes their performance declined if they were stressed compared to when they were not stressed.<\/p>\n<\/li>\n

    3. \n

      For the group that practiced retrieval, stress did not reduce memory performance, even 25 minutes later.<\/p>\n<\/li>\n<\/ol>\n

      In other words, acute stress can inhibit our ability to retrieve what we learned, but if we practice retrieval it seems to protect against this effect. This work has practical implications for students taking high-stakes tests that are stressful. Often students may feel stress in the hours before the exam and during the exam. If students are going to take a test or exam that is particularly stressful, then practicing retrieval in preparation for this test should improve their overall learning and<\/em> help them overcome performance issues related to the stress that they might experience right before and during the exam.<\/p>\n

      On the flip side, there is some research suggesting that higher levels of performance pressure and anxiety, which could be seen as a form of acute stress, during<\/em> retrieval practice may reduce the positive benefits of retrieval practice (3)<\/em>. \u00a0This makes sense; if acute stress harms our ability to retrieve then stress during retrieval practice ought to make retrieval as a learning activity less effective. So, taken together, it seems that low-stakes or no-stakes retrieval practice activities may work best to improve learning, and then subsequently may protect against forgetting that could occur during higher stakes stressful tests, large examinations, or higher stakes situations during which students will need to use their learned information (like in a job interview or job performance).<\/p>\n

      Of course, as always, the results are likely nuanced. It is possible that different types of stress, or the way students experience stress could alter these findings. There is definitely more work to be done in this area!<\/p>\n
