Connectionism and LOT

2) Fast processing via parallelism
• “100 Step” argument.
Neurons change state very slowly compared with computer
computations. Neurons can only process 100 steps a second
(whereas computers can process a million). But the brain can
solve many complex problems in less than 1 second, e.g.
face recognition ⇒ for these, it can use maximally 100 steps.
• Conventional computer programs do mostly serial processing
and usually require considerably more than 100 processing
steps for problems where brains need less than a second.
So, such computers cannot provide a good model of cognition.
• Connectionist computations are done by parallel processing,
thus much more can be achieved in 100 steps.
