Document Summary
3 pegs and 4 disks (small, medium, large, extra large: results: : psychoanalysis would not work if memory was not organized: we wish to examine and formalize. People do better and better after each trial. Two network models: hierarchical network model, spreading activation model. Knowledge consists of sets of features: bird = wings, feathers, beaks, flies. Features weighed on n-dimensional space: small ------------------------------------------------ large, defining: important. How people would decide that something is something else. Encoding: features for bird retrieved and for robin. Stage 1: first decision stage, comparison of all features associated with robin and bird, generate index of similarity/overlap (x) So high that the index would be greater than some upper criterion (cupper) If there is a really large amount of overlap, you say yes a robin is a bird! If it doesn"t even meet the lowest criterion, then just say no. X is lower than upper criterion, but higher than lowest criterion.
