By 18 months, we’ve been exposed to many, many interactions. The right orbitofrontal cortex is providing the final adjustment of the output from our limbic system, regulating our arousal level and emotions up or down.
By the end of the second year, we’ve built up an ability to cope with some fear and stress, and to quickly return to exploring when the situation is safe enough. If it’s not safe, we’re able to quickly seek contact with the parent and come back under emotional control so we can re-energise (a process known as refuelling). We learn to tolerate fear without becoming overwhelmed or lost, and to settle quickly if we do become distressed. This is called a secure attachment.
However, an unhelpful pattern can be set up if the parent is unresponsive, or too responsive, or if their behaviour is inconsistent and the infant is never sure what to expect.
If the parent is too quick to soothe, the infant isn’t exposed to any fear and doesn’t learn any tolerance of stress and discomfort. Over time, the infant will develop a tendency to become agitated, restless and over-aroused.
On the other hand, if the infant is looking for reassurance and it is delayed, or not provided, the infant’s distress increases. If the distress continues to rise, the infant can reach its threshold and suddenly shut down, becoming quiet and still. It learns that help and reassurance should not be expected, so it starts to isolate itself and become lethargic (under-aroused).
Both of these patterns – and a situation where there’s no clear pattern – are called insecure attachments, where the infant’s ability to regulate their emotions is impaired. (A word of caution: no parent can be attentive all of the time, and this is not a platform for judging the quality of our parents – or anyone else’s.)
The quality of the parent–child interaction is more important than the circumstances in which a child grows up. People can be emotionally resilient despite a difficult early family life, while emotional fragility can sometimes emerge from what appears to be a solid family environment.
Memory
The signals we receive from our parent and our reactions to them are absorbed into our memory and act as powerful automatic templates or ‘scripts’ for our responses to later events. By the time we’re 18 months old, encoded memory scripts are ingrained in our limbic system and automatically guide how we manage our arousal in new situations.
During our critical first two years, a huge number of nerve cells are produced, which are pruned back to reflect our dominant reactions, good or bad. Our RED reactions become hard-wired. We form memories of automatic procedures that are either healthy and flexible, or rigid and unhelpful.
Our memories can be divided into two main types:
1 Explicit memories, which encode facts and events
2 Implicit memories, which encode procedures for how to do things
An explicit memory records what happened and when, and labels it as either pleasant or unpleasant. To form an explicit memory, we have to consciously focus our attention, which requires our BLUE mind. But explicit memories are not true records of what happened, because they are also encoded with emotion from our RED mind, which makes them more vivid. In addition, they are influenced by the way we are paying attention at the time. We can generally recall a memory more easily when we’re in the same emotional state we were in when the memory was formed.
Implicit memories are unconscious records that show us how to do something, such as writing. As we’ve seen, these are formed from birth through repeated experiences. We don’t consciously have the experience of ‘remembering’: when we are writing, we just do it. Our implicit memories run automatically.
The early scripts that capture how we think, feel and act in response to cues from our environment are examples of powerful implicit memories. We have no sense of recall when they are triggered; we just ‘find’ ourselves functioning in a certain way that feels entirely natural, whether it is helpful for us or not.
But certain implicit memories formed during childhood can modify this early emotional template, and can have a particularly powerful effect on our performance under pressure.
Shame and trauma
Emotionally overwhelming events are stored in the brain as traumatic memories. Because they are processed in extreme conditions, our memory only records fragments of the event. It seems that during the recording, our RED brain emotion disrupts BLUE brain attention.
Sometimes people do not mentally process the scene and only the body-based experience is recorded as an implicit memory, which is why people can re-experience the same feelings as in the original event, even without a visual memory.
But it’s important to make a distinction between big-T trauma – reserved for major events like natural disasters and violent incidents, commonly associated with helplessness and loss of control – and little-t trauma, referring to lesser events that are not life-threatening but still carry some emotional impact.
In big-T trauma situations, some people can develop highly distressing memories that come into their mind out of the blue. Some powerful memories called flashbacks actually take us back into the moment as if we were re-experiencing the trauma; the sense that it happened in the past is lost. People suffering from post-trauma syndromes have symptoms of high arousal (feeling jumpy and on edge, experiencing flashbacks) or low arousal (detachment, numbness), or both, often swinging erratically between the two.
Most of us have a lot of little-t and perhaps a few large-T traumas encoded in our memory systems. And some of our first little-t traumatic memories date from the attachment process during our early years.
When we become mobile and our parent starts setting limits, we’re suddenly confronted by the sight of their face showing disapproval of our behaviour, and our urge is to feel shame. It’s an abrupt, painful reaction that leads to silence, avoidance of eye contact, and feelings of isolation. These emotions can be seen in the face of a child before they learn to talk.
How we manage shame in early life plays a major role in how we learn to regulate our emotions. These moments are absorbed as implicit memories and become automatic procedures when similar moments are encountered later. If moments of shame are managed well, we’ll be able to maintain emotional control while experiencing moderate levels of discomfort. But if the attachment traumas become consistent, we’ll feel like we can’t tolerate and cope with the strength of the feeling and develop a strong tendency towards becoming anxious and agitated (over-arousal), or washed out and flat (under-arousal) when we become uncomfortable.
None of us can recall our earliest traumatic experiences. But most of us can remember moments of shame or embarrassment from our schooldays – whether we tripped on the stage at school, fluffed our lines in the school play, failed an exam or missed an open goal.
Our RED system doesn’t forget these moments, because they’re moments of social threat. The RED brain is brilliant at storing these moments away as implicit memories, even if we can’t recall the moments explicitly, so it can warn us if similar situations reappear. When that happens, our RED memory of the event – apparently asleep for years but in reality only resting with one eye open – springs to life. It reminds us, in an instant, of the social threat, and our RED survival system is reactivated. It doesn’t matter that these days we don’t consciously recall the original threat; the RED system makes us feel it anyway.
This explains why we can find ourselves in a performance situation, thinking (with our BLUE mind) that we have it under control, but feeling anxious without really knowing why. Our subconscious mind is recognising some aspect of the current situation that is symbolic of the old event, and the old feelings come up. Some subtle aspect of the situation – a tone of voice, certain words, even a smell – triggers our deeply stored
