Psychostimulants act on monoamine systems including the dopamine transporter (DAT), a key regulator of dopamine reuptake following synaptic release. While these compounds can enhance energy, cognition, and sociability, their clinical utility is often limited by their abuse...

This paper proposes that a fundamental organizational trend in biological, cognitive, cultural, and technological evolution is the emergence of progressively more capable representation–interpretation systems. Across these domains, evolution has repeatedly generated systems in...

Modern AI systems are increasingly being evaluated for their ability to reason, code, prove theorems, use tools, and long-horizon research tasks. These are powerful capabilities, but they share a structural limitation: the representational frame within which the model operates,...

What does it mean to understand the world? Contemporary world models often operationalize understanding as accurate future prediction in latent or observation space. Developmental cognitive science, however, suggests a different view: human understanding emerges through the...

A growing body of work points to the great promise of AI systems that can continually expand their capabilities as they operate in an open-ended environment. But yet there is no coherent definition of open-endedness or theory about how an agent ought to explore an open-ended...
