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…

How Occam’s razor guides human decision-making
A rather complex but very interesting article was published @PennLibraries and (somewhat more recent) @bioRXiv But for those who want to understand by a lecture, I can recommend the Simons Faoundation lecture from Joshua Gold (also available on Youtube: How Occam’s Razor Guides Human and Machine Decision-Making) Occam’s razor is the principle stating that, all…

Ten tips for facilitating emergent processes
I just discovered a nice medium article/blog entry from Sonja Blignaut on working towards emergent solutions for wicked situations. I just summarise, but details are in the article. Facilitating emergent group processes requires a different kind of facilitation. When you’re not working towards a predetermined outcome, following a pre-designed agenda, the following principles are helpful…

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…

The evolution of universal cooperation
Humans work together in groups to tackle shared problems and contribute to local club goods that benefit other group members. Whereas benefits from club goods remain group bound, groups are often nested in overarching collectives that face shared problems like pandemics or climate change. Such challenges require individuals to cooperate across group boundaries, raising the…

Brain-Behavior relationships
“Improving the study of brain-behavior relationships by revisiting basic assumptions” discusses how scientific communities tacitly agree on assumptions about what exists (called ontological commitments), what questions to ask, and what methods to use. All assumptions are firmly rooted in a philosophy of science that need not be acknowledged or discussed but is practiced nonetheless. In…

The Art of Abduction
Abductive reasoning typically begins with an incomplete set of observations and proceeds to the likeliest possible explanation for the set. Abductive reasoning yields the kind of daily decision-making that does its best with the information at hand, which often is incomplete. A medical diagnosis is an application of abductive reasoning: given this set of symptoms,…

Beware the “lure of models”
Scientists cannot help but use models says Mark Buchanan. Models help to clarify the consequences of theoretical assumptions, or to draw out complex lines of cause and effect … Without simplified conceptual models, scientific communication itself would be largely impossible.Of course, mathematical models also underlie some of the sciences’ most impressive achievements, like e.g. today’s…

How mathematics invented new realities
Although Euclid’s ideas about geometry in 300 BC were rooted in physical reality, the field became ever more abstract throughout the twentieth century.In her new book, historian Alma Steingart reveals how this push for abstraction was mirrored by, and often triggered, parallel trends in economics, sociology, psychology and political science. (Axiomatics: Mathematical Thought and High Modernism…
