Before reading any further, try a simple experiment. Think of a teacher from your school days. Not necessarily the best teacher you ever had. Not necessarily your favourite. Just the first one who comes into your mind.
I have no doubt that somebody came to you almost immediately. You may be able to picture the classroom. You may remember the sound of their voice, the clothes they wore or a particular phrase they repeated endlessly. You might even recall a specific lesson, despite the fact that years or even decades have passed since you last sat in front of them.
Now, try remembering what you ate for lunch three days ago. Chances are, you’re finding that rather more difficult. This curious imbalance lies at the heart of one of the most fascinating questions in psychology. Why do so many of us retain vivid memories from our school days while forgetting vast stretches of our adult lives?
As a tutor, I am frequently reminded of just how powerful these memories can be. Mention Latin and people often respond not with a discussion about language but with stories about school. Sometimes they remember an inspirational teacher. More often, they recall a terrifying one. They may remember little about the subject (most usually Caecilius est in horto) but they do remember the smell of the classroom and the location of the windows. Such memories remain remarkably persistent.
The human brain is not a recording device. Most of us intuitively imagine memory as something like a video archive, faithfully storing the events of our lives for later retrieval. In reality, memory is selective, reconstructive and deeply influenced by emotion. Not only is the brain constantly making decisions about what information is worth keeping and what can safely be discarded, it reconstructs those memories each time it brings them to mind. From an evolutionary perspective, the process makes perfect sense. A memory system that preserved every detail of every day would quickly become overwhelmed. Forgetting is not a flaw in the system, it is one of its most important features. The interesting question, therefore, is not why we forget so much but why we remember certain things so clearly.
One answer lies in emotion. Psychologists have long known that emotionally significant experiences are more likely to be remembered. This does not necessarily mean dramatic or traumatic events (although those are often disturbingly persistent). Embarrassment, excitement, pride, anxiety, surprise and even mild humiliation can all strengthen memory formation. School provides a quite remarkable number of opportunities for such emotions. The first time a child answers a difficult question correctly or incorrectly in front of their peers. The panic of forgetting a line in a school play. The pride and embarrassment of winning a prize. The horror of realising that homework has been left at home. The embarrassment of calling your teacher “Mum” in front of a class (actually, I’ve even been called “Dad”, which was interesting). Such experiences may seem trivial to an outside observer, yet they provoke heightened emotions at the time and hence become deeply embedded in our memory.
Teachers frequently become part of this process. The teachers we remember are not always the most effective educators. More often, for better or for worse, they are the ones who made us feel something: who inspired us, frightened us, encouraged us, challenged us or infuriated us. Emotion acts like a preservative, signalling to the brain that a particular experience may be worth keeping long-term. Even now, my oldest friend and I can remember how terrified we were of our needlework teacher when we were 13. Her favourite method of crowd control was ritual humiliation. “Everyone gather round to see how badly Ros is doing this,” is a classroom memory we will both take to the grave. To this day, I genuinely wish I had found the courage to defend my friend and told that teacher exactly where she could shove it. Exclusion would have been 100% worth it.
School provides us with a series of novel firsts. Much of adult life is surprisingly repetitive and the very predictability that makes adult life manageable can make it difficult to remember. One Tuesday begins to resemble another. Childhood is different, since everything is happening for the first time. Our first day at secondary school. Our first examination. Our first close friendship, the loss of which can be our first taste of heartbreak. Our first major disappointment. Such experiences define our narrative. All of this helps to explain why our memories of school often feel so vivid. It was not necessarily that school itself was more memorable than adult life. Rather, our experiences in school were a plethora of firsts, which our growing brains identified as key events in our evolving self-definition.
In addition to the inescapable fact that our school days introduce us to a series of first-time experiences, it is also important to remember the profound effect that experiences have on us when they happen during our younger years. Psychologists have identified a phenomenon known as the “reminiscence bump”, one of the most intriguing findings in memory research. When older adults are asked to recall events from their lives, they tend to remember a disproportionate number from childhood, adolescence and very early adulthood. Memories from these years appear unusually durable. I have witnessed this first-hand as I have watched my parents age: both of them, now in their 80s, talk more about their childhood and their youth than they have ever done before. Researchers continue to debate exactly why this occurs, but it is a recognised side-effect of ageing and several explanations have been proposed. Our younger years are often characterised by major life transitions and significant personal development; we form identities, establish relationships, make important decisions and experience many of life’s defining moments. That period also coincides with a time when the brain is laying down new neural pathways and thus appears to be particularly sensitive to memory formation. I find this the most interesting part of current theory: many neurologists believe that the changes that the brain is going through during adolescence and our early 20s are as significant as those that happen during our first two to three years of our lives.
For all of us, education is not simply something we experience, it is the environment within which much of our identity is formed. For some people, the experience is something they never quite recover from, and a significant challenge faced by schools is managing the feelings and prejudices projected by some parents for whom school was a thoroughly traumatic experience. For some, school was such a place of struggle and of negative comparison of oneself to others that it becomes associated with entirely negative experiences. School is where many people first encounter challenge and failure and it can be difficult for some adults to let go of the powerfully negative associations they may have towards education as a result.
All adults inevitably revisit their own experiences of school when their own children join the classroom. This sparks memories and every time a memory is reconstructed, it is updated and made more vivid. The past remains alive because we keep returning to it. This process can sometimes create the illusion that we remember school more accurately than we actually do. Every act of remembering involves a degree of reconstruction and we do not retrieve memories so much as rebuild them. This helps to explain why siblings who attended the same school often remember it so differently. They are not recalling a shared objective reality: they are reconstructing experiences through the lens of their own emotions, personalities and subsequent lives.
As somebody who has spent much of my professional life working in schools, I find all of this both fascinating and sobering. Teachers rarely know which moments students will remember. The lesson that took hours to prepare may vanish entirely from memory, whereas a careless throwaway comment may still be remembered forty years later. I am painfully aware of this. Our school experiences occur at precisely the moment when our identities are taking shape, when all of our experiences are new and our emotions feel most intense. The result is a collection of memories that can remain astonishingly vivid for the rest of our lives.
