“mundane behaviours resembles a drug”
The problem extends across the globe. Researchers have studied compulsive shopping in many countries, including the United States, Turkey, Poland, Germany, India, Brazil, South Korea and Pakistan — where almost one-third of university students were classified as compulsive buyers in both physical stores and online.Heping He, a marketing researcher at Shenzhen University in China, is…

Explanation in Biology
The most recent publication from the series “Philisophy of Biology” is “Explanation in Biology“, available for free download at the site. The book introduces and elaborates scientific explanations in biology and the life sciences. Explanations are viewed as a “primary” objective of science – theyoffer deep understanding and knowledge of the world, as opposed to…

The unbearable slowness of being …
The unbearable slowness of being: Why do we live at 10 bits/s? This article is about the neural conundrum behind the slowness of human behavior. The information throughput of a human being is about 10 bits/s. In comparison, our sensory systems gather data at ∼109 bits/s. The stark contrast between these numbers remains unexplained and touches…

Affect-centered account of motivated behavior
“The affective gradient hypothesis: an affect-centered account of motivated behavior“: everyone agrees that feelings and actions are intertwined, but cannot agree how. According to dominant models, actions are directed by estimates of value and these values shape or are shaped by affect. The article proposes instead that affect is the only form of value that…

regulation of motivated behavior
in “A unified theoretical framework underlying the regulation of motivated behavior“, Yu-Been Kim, Young Hee Lee, Shee-June Park and Hyung Jin Choi explain that multiple psychological components have evolved in order to orchestrate behaviors for survival. Despite several theories regarding behavior regulation, these theories do not clearly distinguish distinct components and do not explain the…

exploring One Health
The eco-epidemiology of zoonoses is often oversimplified to host-pathogen interactions while findings derived from global datasets are rarely directly transferable to smaller-scale contexts. Through a systematic literature search, we compiled a dataset of naturally occurring zoonotic interactions in Austria, spanning 1975–2022. We introduce the concept of zoonotic web to describe the complex relationships between zoonotic…

energetic cost of allostasis and allostatic load – do not stress
Chronic psychosocial stress increases disease risk and mortality, but the underlying mechanisms remain largely unclear. This article in Psychoneuroendocrinology outlines an energy-based model for the transduction of chronic stress into disease over time. The energetic model of allostatic load (EMAL) emphasizes the energetic cost of allostasis and allostatic load, where the “load” is the additional…

Fast walkers have higher IQ and larger brains than slow walkers.
These findings are from a 5-decade cohort study of 904 participants in New Zealand published in @JAMANetworkOpen which tested the hypothesis that slow gait speed reflects accelerated biological aging at midlife. Slow gait was associated with multiple indices of compromised structural brain integrity, including smaller total brain volume, global cortical thinning, and reduced total surface…
