Shifting attention
The Internal Dominance over External Attention (IDEA) hypothesis (I referred to earlier) asserts, contrary to the traditional view of attention as being primarily externally oriented, that attention is inherently biased toward internal information. A related work on attention switching has been published: “Shifting attention between perception and working memory“ Most everyday tasks require shifting the…

42 and 5
Today, 42 years ago, we had the great pleasure of discovering the reality of 5-fold crystals. On the morning of 8 April 1982, an image counter to the laws of nature appeared in Dan Shechtman’s electron microscope. In all solid matter, atoms were believed to be packed inside crystals in symmetrical patterns that were repeated…

Limitarism – A bliss
Ingrid Robeyns’s Limitarianism: The Case Against Extreme Wealth, a powerful case for limitarianism–the idea that we should set a maximum on how much resources one individual can appropriate. A must-read! (so says Thomas Piketty). Ingrid Robeyns’ Limitarianism is a recent addition in a long line of critiques – such as Thomas Piketty’s Capital and Branko Milanovic’s Visions of Inequality – of the…

Bayesian model: prior–cost
Sohna and Jazayeri discuss in “Validating model-based Bayesian integration using prior–cost metamers” the two competing views on how humans make decisions under uncertainty. Bayesian decision theory (BDT) posits that humans optimize their behavior by establishing and integrating internal models of past sensory experiences (priors) and decision outcomes (cost functions). An alternative hypothesis posits that decisions…

Representation of priors and decisions
The PLOS article by Marshall, Ruesseler, Hunt, O’Reilly “representation of priors and decisions in the human parietal cortex” discusses how both humans and animals actively sample the environment using their sensory organs, far from being passive recipients of sensory information. In rodents, active sampling processes include whisking and sniffing; in primates, the most important and…

It Takes Two To Think
The title refers to the recent article by Yanai & Lercher. (Itai Yanai is a Professor at the NYU School of Medicine. Martin Lercher is Professor at Heinrich Heine University Düsseldorf at both the Institute for Computer Science and the Department of Biology. ) At the heart of science is a creative ‘night science‘ process,…
