Is it better to reread my session notes or to try to remember them without looking?

In a meta-analysis of 159 comparisons, trying to recall something on your own outperformed reading it again for later retention, by a moderate amount. Both have a place, but if the goal is holding on to what you learned, active recall was the stronger tool.

How often should I check back in with what I learned in a session?

The research on the testing effect suggests short, spaced attempts beat one long review. A minute or two, a few times across the week, tracked with better retention than a single sit-down at the end. Consistency mattered more than length.

What if I cannot remember much from my last session?

That is common, and the research still points in a helpful direction. In these studies, effort during retrieval was itself part of what strengthened memory, even when people did not remember everything. Feedback afterwards helped, which is one reason bringing what you did remember to your next session is useful.

The Wait

How do I hold on to what I learned between sessions?

Short answer

To hold on to what you learned between sessions, do not just look over your notes. Bring what you learned to mind on your own, out loud or on paper, in short moments across the week. In memory research, that kind of active retrieval is what makes learning last.

Sample 159 effect sizes from published testing-effect experiments

Published 2014

Journal Psychological Bulletin

Christopher Rowland pulled together 159 comparisons from published experiments on the testing effect, the finding that trying to recall something sticks better than reading it again. Across those studies, being tested on what you had learned beat re-reading it, with a pooled effect size of about 0.50 in Hedges's g, and a 95 percent confidence interval from 0.42 to 0.58. That number is a moderate effect, which means a clear and useful difference, not a tiny one and not a miracle. The pattern held up across a wide range of study designs. The effect was larger when the material was more complex, when the retrieval took real effort, and when the person got feedback on how they did. Rowland's read was steady. On average, calling something back to mind is a stronger way to keep it than reading it again.

What does this mean for you?

The finding here is not about school or exams. It is about how memory works. The hour you spend in a session opens something up. In the days that follow, most of what you do with that new understanding is quietly deciding whether it fades or holds. Reading your notes again feels like the honest way to keep the work close, but the research suggests it is a weaker signal to memory than calling the material to mind on your own.

Be clear about what this study can and cannot say. It looked at learning verbal material in controlled experiments, not therapy specifically. Whether the same size of effect shows up when the material is a moment of insight, rather than a list of facts, is not something this paper tested. What it does support is a simple principle: the act of trying to bring something back is itself part of how it stays. Read it as a useful direction, not a promise about your own path.

What matters for you is the plain part. You do not need a new practice or a big system. You need small moments across the week where you close the notebook, or the app, and try to say back what your last session was about. If it will not come at first, that is normal. The trying is doing the work, even when the memory feels blurry.

The takeaway

Try to recall, not just reread. Close the notebook for a moment and say back one thing from your last session.
Little and often beats one long review. A minute here and there across the week is enough to help it hold.
Let feedback in. Bring what you remembered to your next session, so your care team can help fill in what shifted.
