Split attention is a ‘feature’

Split attention is a ‘feature’

“neuroscientists have determined that humans lose focus on whatever task they’re participating in four times a second in order to take stock of their environment. Since a similar study with macaques (short-tailed monkeys found in regions of Asia and Africa) achieved the same result, researchers believe that this shift in focus is an evolutionary tool primates use to react to an ever-shifting environment and avoid threats from predators. On one level, this is an excellent example of embodied cognition in…

Winter 2020 discussion prompts

What is humanity’s situation with respect to surviving long-term with a good quality of life? (Frame the core opportunities and obstacles.) What attributes of our evolved, experientially programmed brains contribute to this situation? (What are the potential leverage points for positive change within our body-brain-mind system?) What courses of research and action (including currently available systems, tools, and practices and current and possible lines of R&D) have the potential to improve our (and the planetary life system’s) near- and long-term…

Kin and multilevel selection in social evolution

Kin and multilevel selection in social evolution

In the “development and evolution” thread on Thompson, Paul dismissed and contrasted him with “people who actually study organisms.”  Hence my latest referenced articles are by exactly those people that do. And even among the experts in the know there are differences and disagreements. Another such article confirming this is “Kin and multilevel selection in social evolution: A never ending controversy?” (The abstract is below.) Some adamantly choose one side of the debate, others like this article seeks some semblance…

Multilevel selection theory and economics

Multilevel selection theory and economics

Article by evolutionary biologist David Sloan Wilson. Some excerpts: “Evolutionary theory’s individualistic turn coincided with individualistic turns in other areas of thought. Economics in the postwar decades was dominated by rational choice theory, which used individual self-interest as a grand explanatory principle. The social sciences were dominated by a position known as methodological individualism, which treated all social phenomena as reducible to individual-level phenomena, as if groups were not legitimate units of analysis in their own right (Campbell 1990). And…
