Software, Affordance, and our Collective Nature

Friday, January 23rd, 2009

Here is an interesting project . Computers are introduced into the wild (a rather romantic notion). Slum kids (who?) in India are exposed to computers without the benefit of any further guidance. No adults. No instructions. In an experiment repeated several times now, they go through several ...

Abstraction and concreteness, complexity and simplicity

Wednesday, April 30th, 2008

In a now classic article from 1977, Sverker Runeson observed that variables which we scientists consider to be basic, such as length, duration, etc, may or may not be basic from the point of view of opportunistic, evolved perceptual systems.  He suggests that perception may consist of "smart mechanism" which ...

In treats of people with body dysmorphic disorder, in which sufferers perceive themselves as flawed based on very little evidence. Functional MRI has ...

Enaction and the PMF

Monday, February 25th, 2008

More and more, I find that the vision of being I am outlining here and in the sister site is one that aligns well with the enactive approach in Cognitive Science.  I try not to read too much ahead of me, but when I do read in this area, things ...
