As such it cites some of the same studies and examples I drew on while writing <i>Blindsight<\/i>.  But what especially interested me was the suggestion of <i>mechanism<\/i> behind some of those results.  Both <i>Blindsight<\/i> and Blog cite studies showing that being distracted from a problem actually improves your decision-making skills, or that we are paradoxically better at detecting subtle stimuli in &#8220;noisy&#8221; environments than in &#8220;clean&#8221; ones.  Koch and Tsuchiya cite a paper that describes this as a form of <i>competition between neuron clusters<\/i>:<\/p>\n<blockquote><p>&#8220;attention acts as a winner-takes-all, enhancing one coalition of neurons (representing the attended object) at the expense of others (non-attended stimuli). Paradoxically, reducing attention can enhance awareness and certain behaviors.&#8221; <\/p><\/blockquote>\n<p>I like this.  It&#8217;s almost <i>ecological<\/i>.  Predators increase the diversity of their own prey species by keeping the most productive ones in check;  remove the starfish from a multispecies intertidal assemblage and the whole neighborhood turns to mussels inside a month.  This is the same sort of thing (except it happens within a single brain and therefore tastes more of Lamarck than Darwin).  Different functional clusters (the different prey species) duke it out for attention, each containing legitimate data about the environment&mdash; but only the winner (i.e., the mussels) gets to tell its tale to the pointy-haired boss.  All that other data just gets <i>lost<\/i>.   And the static that paradoxically improves performance in such cases &mdash;  white noise, or irrelevant anagrams that steal one&#8217;s focus &mdash; play the role of the predator, reducing the advantage of the front-runner so that subordinate subroutines can get their voices heard.<\/p>\n<p>I wonder. If we trained ourselves to live in a state of constant self-imposed distraction, could we <i>desentientise<\/i> our own brains&#8230;?<\/p>\n","protected":false},"excerpt":{"rendered":"<p>New to me, old to the lit: a paper in Trends in Cognitive Sciences, which came out last November (just a month after Blindsight was released): &#8220;Attention and consciousness: two distinct brain processes&#8220;.
