Triggers and Neuroplasticity; Why Can Something Small in the Present Evoke a Strong Reaction from the Past?

One of the brain’s learning mechanisms is the formation of associations between events that occur close together in time. For example, a child who experiences repeated criticism whenever they make a mistake may learn to associate making a mistake with feelings of shame or a threat to their self-worth. In adulthood, even moderate professional feedback may evoke a strong emotional response.

The brain does not have to consciously recall the original experience for the learned association to influence the response. At the same time, not every intense emotional response indicates trauma, and it is not always possible to identify a particular event in which the learning took place.

When an association between a stimulus and a response grows stronger over time, the response may occur quickly and without prolonged conscious thought. This automaticity is an important part of human learning. It allows us to perform familiar actions efficiently, but it may also maintain patterns that are not helpful to us. For example, a person who has learned that expressing disagreement leads to conflict may feel an urge to agree with others, even when they want to express a different view. In such a situation, automatic agreement may be a learned way of reducing discomfort.

A response to an emotionally meaningful stimulus involves the coordinated activity of brain networks responsible for learning, memory, evaluating meaning and regulating behavior. The amygdala is involved in emotional learning and identifying significant stimuli, while areas of the prefrontal cortex participate in assessing the situation and adapting the response to its context. This is not a simple struggle between an “emotional brain” and a “rational brain.” These systems interact and influence one another. When a stimulus evokes a learned response, a person may experience the emotion before they have had time to consciously examine the meaning of the event.

One of the important principles of neuroplasticity is that previous learning is not necessarily irreversible.

When a person encounters a familiar stimulus under different conditions, they may acquire new learning that gradually changes their response. Suppose a person associates criticism with humiliation. When, over time, they experience receiving respectful feedback while also developing new ways of interpreting and responding to it, different emotional learning may emerge. The process does not require the original association to be erased. Sometimes the new learning exists alongside it and gradually has a greater influence on behavior.

New learning depends on various factors, including the intensity of the experience, the degree of attention, the context in which it occurred and the opportunity to repeat it. A single positive experience may be meaningful, but it will not always be enough to change a pattern that has grown stronger over many years. In addition, a response that has weakened in one environment may reappear in another environment or during a period of stress. This does not necessarily indicate that the process has failed. It reflects the fact that emotional learning is influenced by context and that change does not always develop uniformly.

Therapeutic work can combine several learning processes, depending on the nature of the difficulty.

• Identifying a pattern: Understanding the association between a particular stimulus and the response it evokes.
• Examining meaning: Identifying the beliefs and expectations the person attaches to the situation.
• A corrective experience: Creating tailored, safe opportunities to experience a familiar situation differently.
• Practicing a new response: Developing an alternative behavior and strengthening it through repeated experience and feedback.

For example, a person who tends to avoid expressing an opinion for fear of rejection can gradually practice expressing a personal view in a safe environment.

When trauma is involved, the work must be adapted to the person’s condition, and uncontrolled exposure to stimuli that evoke distress must be avoided.

To learn from experience, it is important that a person can engage in the process to a degree that suits their abilities. When distress is too intense, it may impair attention, concentration and the ability to process new information. Conversely, completely avoiding any discomfort may limit opportunities for learning. Therapy therefore requires a balance between the level of challenge and the person’s sense of capability and safety.

The goal is not to create a situation in which there is no difficulty at all, but to allow an experience that the person can tolerate and process.

Life experiences help shape our patterns of responding. Some are helpful and protect us, while others may continue to operate even when conditions have changed.

Neuroplasticity allows the nervous system to adapt to new information and experiences, but it does not mean that every pattern can be changed quickly or completely.

The therapeutic implication is that a response learned in the past does not have to be the only option in the present. Through a tailored process, the range of responses available to a person can gradually be expanded.
