Lossy compression of a complex world
What is the relationship between complexity in the world and complexity in the mind? The mind engages in a kind of lossy compression for overly complex stimuli.
simplicity and complexity
in the world and the mind
My name is Zekun (hear my name). I'm a postdoctoral researcher at Yale University, working in ACT Lab. I earned my PhD in Cognitive Psychology at Johns Hopkins University, where I was part of Percaption and Mind Lab.
The world frequently strikes us as being simple or complex. But why do our minds bother to represent complexity in the first place? My research seeks to understand how the mind computes the complexity of information and how the mental representation of complexity shapes our interactions with the world. I’m not only interested in the connections between the complexity of stimuli and the complexity of their representations, but also in the evolution of mental complexity across different cognitive processes to serve various epistemic and pragmatic goals. Lately, the question that keeps me awake at night is how the mind knits a sequence of stimuli and builds coherent representations over time.
Here is my CV.

Some objects look ‘curious’. In this paper, I explore how complexity is a visual feature that automatically guides our attention and engagement.
A plain, blank canvas doesn’t look very beautiful; to make it aesthetically appealing requires adding structure and complexity. But how much structure is best? Is there a ‘sweet spot’ of perceived complexity?
The world contains not only objects and features, but also relations holding between them. How do such relations form in the mind?
Memory rarely replicates exactly what we see; instead, it reconstructs past experiences with distortions and errors. Does memory enhance the complexity of what we see?
How does the mind cope with complexity of the world? How does that matter?
