Cost of Multitasking
Multitasking is really task-switching — and every switch has a cost. A cognitive enhancement researcher separates the solid science of switch costs from the shaky claims of permanent focus damage, and shows how to switch less.
Working Memory: What It Is and How to Expand It
Working memory is the cognitive function most directly responsible for how intelligent you seem — and how intelligent you feel. Understanding its biological capacity limit (4 ± 1 chunks), why the prefrontal cortex is uniquely vulnerable to stress and sleep deprivation, and the specific interventions with RCT evidence for improvement is the difference between vague advice and a precision protocol. This guide covers the neuroscience, the clinical evidence, and the four-layer optimisation protocol that Peter has refined across 40+ Creyos testing sessions.
Deep Work: The Neuroscience of Distraction-Free Productivity
Deep work isn’t a willpower problem — it’s an attention-protection problem. The real science of sustained focus, why the “23 minutes” myth is wrong, and the exact protocol Peter uses.
