Document Summary

Edge detecion brain segregate objects based on the edges percepion of the world. How well the outside world is interpreted by us. Connecionist models: use neuron-like components to do things. Faster to read an underlined word when it appears within the context of a word than a non-word. For it to be a word, we have to know the leters. Model predicts word superiority efect due to top down processing. Property of rules: no rules, only mathemaical connecions. Thinking and percepion are related to one another. Even if some units don"t work, informaion sill preserved. Progressive difereniaion: as kids get older, more disincion between things (conceptual development) Model of memory on how things relate: taxonomic hierarchy. Learns over ime to difereniate concepts and their properies. Change the strength of the connecion between the nodes. Change connecions so it gets closer to the right answer. Brain when learning: establishing/ weakening neural connecions (strength of connecions)
