Document Summary
Remarkable ability of humans to recognize distinct sensory stimuli as the same pattern. For example: reading different samples of handwriting -- can read it relatively easily/smoothly. Ex: distinguishing between humans & computers -- identify a distorted word in order to enter a site. This kind of pattern recognition is easy for people, difficult for computer search programs. We don"t have a one-to -one correspondence between the sounds (phonemes) in speech and our recognition of the phonemes. Ex: difference between perception of rider and writer -- difference is duration of vowel before der (context!!) B sound at beginning and end of the word bob is very different -- but we perceive it as the same thing. Human perceptual system can adapt to that almost immediately. Look at what the mouth is doing when it creates a particular sound -- changes as a function of the upcoming word. Getting a different stimulus input dependent on the next word that"s going to occur.
