Document Summary

Network makes mistakes misreads and misinterprets. To maximize accuracy read very slowly. To maximize efficiency read some letters and make inferences about the rest. A mechanism through which detectors can inhibit one another, so that the activation of one detector can decrease the activation in other detectors. Better able to id well-formed strings than irregular strings. More efficient in identifying characters in context as opposed to isolated. Connections that allow one detector to activate its neighbors. Ex. detection of t excites trip detector. The activation of one node decreases the activation of another node. Ex. detection of g inhibits trip detector. Higher-level detectors (word detectors) influence lower-level detectors and detectors at any level can also influence other detectors at the same level. Trip is briefly shown but only r, i, and p are identified. Letter detectors fire activate trip detector. Inhibit other word detectors like trap or take. Less likely to arise as distractions or competitors with the target word.
