Intelligence II: Prediction (04/03/09)
Document Sample Understanding the world through abstract neurological representations (as discussed in the previous post) is a wonderfully flexible adaptive strategy which makes all kinds of learning possible. However, in order for the strategy to be viable it must somehow produce information that is accessible in real time, or at least at biologically relevant speeds. According to Christof Koch, experimental psychology suggests that the amount of time necessary to consciously resolve a visual percept is on the order of a quarter-second (the pre-conscious processing of intelligence begins to react on much shorter time frames, and lies behind such concepts as "subliminal marketing, " but is also by definition non-conscious). How then can the representational platform of intelligence make it possible for humans to execute cognitively complex tasks in real time, like hunting a deer, driving a car, or performing Dvorák's magnificent cello concerto?
The answer has to do with architecture. The reason intelligence is able to effect conscious control of events on short time scales is that it confers the ability to plan ahead, thus overcoming its own inherent neurobiological speed limits, by making predictions of future events based on information already received. Very roughly

Basic Computer Software -- Thinking of purchasing a new computer? Think twice before you fork over the funds for a bunch of extra software. There are some great alternatives to the name brand software programs. The most notable is OpenOffice, the open-source alternative to those other guys. It's completely free and files can be exported in compatible formats.
Your Credit Report -- You don't have to pay for your credit report. You could sign up for one of the free credit monitoring services online to get a quick look at your credit report. You just have to remember to cancel the service before the end of the free trial. Or you could do one better and visit the only truly free place to see all three of your credit reports for free once a year.
Cell Phone -- The service plan...
