How Does Our Attention Shape Our World?

Perception, the Nervous System, and Our Everyday Experiences

"What we focus our attention on tends to grow."

In recent weeks, this sentence has been appearing in different contexts and sources around me. I encounter it while studying how the nervous system works in my course notes. I hear it as a line in a film. I recently became curious about quantum physics, and it appears there as well. While working on my master’s thesis—where I explore the physiological, psychological, and social psychological aspects of emotional dysregulation—I realized that I was actually encountering different reflections of the same idea.

If we begin from the field of psychology, this phenomenon is often explained through the concept of selective perception. The human mind does not perceive the world exactly as it is. Instead, it highlights certain aspects and pushes others into the background based on past experiences, learned patterns, and the needs of our inner world.

In psychoanalytic theory, two important mechanisms are often mentioned in this context: repression and projection. A person may repress emotions or desires that feel difficult or threatening. Later, traces of these unresolved elements can begin to appear in the outside world. In other words, if there is an unresolved issue within us, we often start noticing it repeatedly in our surroundings.

There is also a proverb: “People tend to assume that others are like themselves.” In a sense, we are talking about something similar here. As a simple example, imagine going through a period in which you feel that you are not valued enough. During such times, you may notice yourself interpreting even small behaviors from others as signs of being undervalued. A sensitive point inside us can become more visible in the outside world.

When we look at this from a neurophysiological perspective, the autonomic nervous system comes into play. The autonomic nervous system is a powerful mechanism that helps us survive, shaped by our lived experiences, social learning, and even intergenerational transmission. However, this system does not operate with complex concepts such as time, interpretation, or contextual meaning. For it, the primary concern is whether something supports or threatens survival.

In everyday life, this mechanism works as follows: when a threat is perceived, the defensive system is activated and produces a response designed to neutralize the threat. But if a person cannot produce the response their body needs in that moment—if the defensive cycle cannot be completed—the nervous system may fail to recognize that the threat has passed. In such cases, a person may remain in a defensive state for a prolonged period.

When this happens, emotional regulation becomes more difficult. Emotions such as anger, fear, insecurity, or disappointment may arise more frequently and more intensely. We begin responding to situations through these emotional filters, interpreting people through these emotions, and trying to solve problems from within that same emotional state. In other words, once the nervous system begins operating from a threat-focused perspective, we may start perceiving the world through that same lens.

More recently, while exploring quantum physics, I came across an interesting idea related to attention and observation. Some experiments on the behavior of subatomic particles suggest that the presence of an observer may influence the outcome of an experiment. I do not interpret this as a literal physical claim about reality, but I do find it thought-provoking in terms of how attention can shape experience. What we pay attention to tends to become more visible in our experiential field.

I observe something similar in what are sometimes called “knowing field” practices. In family constellation work, ancestral healing circles, or sharing circles, there is often a specific theme that brings people together. And quite often we notice that the participants gathered there have experiences closely related to that theme. We say, “What a beautiful coincidence.” In these spaces—where I believe synchronicity often operates—when we focus our attention on a certain topic, the participants’ stories tend to illuminate that theme from different angles.

We can also observe a similar phenomenon in our everyday interactions with the internet algorithms. Social media platforms, music or audiobook apps, and streaming services gradually learn our preferences and start recommending similar content. Sometimes we enjoy this feature because it helps us discover new things that match our tastes. At other times, it can feel limiting, as if we are being placed into a narrow category or algorithmic bubble.

I notice this very clearly in one area of my own life: detective stories. Since childhood, I have loved crime novels, detective series, and mystery films. When I read a few books or watch a couple of shows in this genre, suddenly all my platforms start recommending similar content. However, most of these stories share a similar atmosphere: a melancholic detective, a dark crime narrative, often more than one victim. Even if the story eventually reaches a resolution, the narrative is often filled with emotions such as despair, horror, and defeat.

When I watch too many of these series in a row, I notice that these emotional tones begin appearing more frequently in my everyday life as well. It feels as if my mind continues to wander within the same atmosphere.

At such times, I try to make a small shift. I start listening to concert recordings that uplift me, or I turn toward content with a more vibrant and lively energy. After a while, I notice that both the algorithm and my own emotional state begin to move in a different direction.

This raises an interesting question:

Can we consciously use this same mechanism in our own emotional lives? How can we move from a defensive state focused purely on survival toward a more balanced and life-supporting way of being?

From what I have learned in my training and observed in my sessions, I believe that healing and growth begin precisely in this space where we learn to guide our attention.

The first step is awareness. Noticing the patterns we struggle with—the situations that seem to repeat themselves and that we believe we have no choice but to endure. Instead of immediately trying to analyze who is responsible, what happened, or when it began, we start simply by observing. Without blaming others—and most importantly without blaming ourselves—we allow ourselves to see the pattern.

The next step is a healthier response. Rather than automatically repeating the same habitual reaction, we begin to create space for the response that our nervous system actually needs in that moment. Sometimes this may mean expressing an emotion that was never voiced. Sometimes it may mean setting a boundary. Sometimes it may mean allowing ourselves to grieve a loss we never fully processed.

In other words, instead of repeating the same cycle, we allow the unfinished defensive response to be completed. This makes it possible not only to hold on to an experience, but to truly complete it—and eventually let it go.

Ultimately, this opens the possibility of growing our sense of well-being. As space opens in our minds, nervous systems, and hearts, we become more able to imagine, see, and experience what is good and beautiful. Our attention begins to move toward new possibilities. We form different kinds of relationships and gravitate toward experiences that nourish us. We start seeing the world from a broader perspective—not only noticing what we need to be cautious about, but also recognizing what is good, supportive, and meaningful. In doing so, we also begin to grow the best parts of ourselves.

This does not mean that we will never encounter difficult situations again. The autonomic nervous system and selective perception may still generate constricting reactions at times.

But once we have successfully navigated such an experience—once we have discovered new responses—it becomes much easier to find our way back toward what is life-supporting and good.

May you experience moments of joy that warm your heart, bring a smile to your face, and spread outward to others.
