How do our brains create rich, ever-changing social impressions from faces?
When you look at someone’s face, you might instantly get a sense of whether they’re trustworthy or dominant—these quick judgments seem almost instinctive. But beneath that rapid assessment lies a complex web of neural processes that weave together visual cues, personal experiences, and cultural influences. It’s as if your brain is running a dynamic, high-dimensional map, constantly updating and refining your social impressions based on more than just what’s immediately in front of you.
For many years, researchers have thought about social impressions—like trustworthiness or dominance—as emerging from a handful of fixed, simple dimensions. It’s like trying to reduce the rich tapestry of human interaction to just a couple of colors. But recent insights suggest that our perceptions are far more fluid and adaptable, shaped by a vast, high-dimensional space within our neural networks. Imagine walking through an intricate landscape where every step is influenced by countless visual, conceptual, and contextual factors blending seamlessly together. That’s what a high-dimensional model of social impressions proposes.
Why your social perceptions are more like a complex journey than a straight line
Instead of thinking about social impressions as static points on a simple scale, picture them as a trail of evolving impressions—like a river flowing through a vast, multi-layered terrain. Each new visual cue, each interaction, and each cultural context acts as a gentle push or pull, guiding your neural pathways along a dynamic trajectory. This idea is rooted in attractor neural-network models, which describe how our brain’s neural states settle into stable patterns over time, influenced by both immediate visual stimuli and broader social concepts.
This means that your impression of someone isn’t fixed the moment you see their face. Instead, it’s a fluid process, constantly adapting as your brain integrates visual cues with your memories, social knowledge, and cultural norms. If you’ve ever found your opinion shifting after hearing someone’s story or observing their behavior, you’ve experienced this high-dimensional dance happening inside your mind.
How cultural and situational factors shape social perception in surprising ways
Traditional models of social perception often overlook how much your background, environment, and even your current mood influence your impressions. The high-dimensional framework recognizes that social judgments aren’t just about facial features but are shaped by a rich tapestry of contextual factors. Your cultural upbringing, personal experiences, and the situation you’re in all influence how your brain maps social cues onto your internal landscape.
For example, a facial expression that signals trustworthiness in one culture might not have the same meaning elsewhere. The high-dimensional approach accounts for these variations, showing that impressions are not just universal but are flexible, adaptable constructs emerging from complex neural interactions. This perspective helps explain why two people might see the same face differently, based on their unique internal maps.
What does this mean for understanding human connection and communication?
Recognizing that social perception is a high-dimensional, dynamic process opens new pathways for empathy and effective communication. It suggests that judgments are less about fixed traits and more about ongoing neural negotiations influenced by context, history, and individual differences. When we understand that impressions are fluid, we become more tolerant of differing perceptions and better equipped to navigate social complexities.
Furthermore, this model offers promising avenues for developing AI and social technologies that better reflect human nuance. By appreciating the high-dimensional nature of social impressions, designers can create systems that adapt more naturally to diverse cultural and individual differences, fostering more authentic interactions.
In the end, appreciating the richness of how we perceive others enriches our understanding of human connection. Our social impressions are not static labels but vibrant, evolving trajectories shaped by a multitude of factors—each moment offering a new perspective in the ongoing dance of social cognition.

Abstract: People form social impressions from visual cues such as faces, which are argued by various models to arise from some limited set of fixed dimensions (e.g., trustworthiness and dominance). We argue that these dimensions, rather than reflecting intrinsic mechanisms, emerge from adaptive visuo-semantic processes in a high-dimensional neural-state space. Drawing on attractor neural-network models, we propose a framework treating social impressions as dynamic trajectories that stabilize over time, influenced not only by visual cues but also by conceptual associations and higher-order social cognition. Unlike low-dimensional models, this framework can account for cultural, individual, and situational factors that shape impressions. A high-dimensional framework makes several novel predictions and can offer a more accurate and complete understanding of the fluidity and complexity of social perception.
