Perceived time & heartbeat
This blog entry about the Current Biology article “Perceived time expands and contracts within each heartbeat” relates perfectly to my previous blog on “cardiac activity: its role in perception and action“ Perception of passing time can be distorted. Emotional experiences, particularly arousal, can contract or expand experienced duration via their interactions with attentional and sensory…

Cardiac activity: its role in perception and action
Patterns of cardiac activity continuously vary with environmentaldemands, accelerating or decelerating depending on circumstances. Simultaneously, cardiac cycle affects a host of higher-order processes, where systolic baroreceptor activation largely impairs processing. However, a unified functional perspective on the role of cardiac signal in perception and action has been lacking. — Patterns of cardiac activity continuously vary…

Human innovation depends on our collective brains
A recent study investigates hunters’ causal understandings of bow design and mechanics among the Hadza, one of the last remaining foraging populations. The results suggest that sophisticated technology can evolve without complete causal understanding. Human innovation depends not on our individual brainpower but on our collective brains, on networks of diverse minds sharing information, lucky…

“A New Evolutionary Law”
Revisiting Leigh Van Valen’s “A New Evolutionary Law” (1973) by Ricard Solé, (Biological Theory (2022) 17:120–125) Now, here, you see, it takes all the running you can do, to keep in the same place. Lewis Carroll, Through the Looking-Glass Leigh Van Valen was an American evolutionary biologist who made major contributions to evolutionary theory. He is…

Ecosystems – Mutualism – Synthetic biology
Synthetic Mutualism and the Intervention Dilemma describes how ecosystems are complex networks of interacting individuals co-evolving with their environment. As such, changes to an interaction can influence the whole ecosystem. However, to predict the outcome of these changes, considerable understanding of processes driving the system is required. Synthetic biology provides powerful tools to aid this…

The Niche theory : Compete, Facilitate & Mutualisme
From competition to facilitation and mutualism: a general theory of the niche by Koffel, Daufresne and Klausmeier explores the niche theory. Niche Theory is a central framework in ecology based on the recognition that most interactions between organisms are indirect, mediated by the biotic and abiotic dynamical environment these organisms live in. Despite its potential…

Can Creativity Be Stored? Yes, and It Should Be
For those of us who are not creative, it is difficult to imagine how creative people work.The explanation for the messy creative person and the uncreative brainstorming session can be found in research by Poornika Ananth and Sarah Harvey published in Administrative Science Quarterly. They had a big study of creative individuals in theatre and architecture, and…
