Collins and Quillian $(1969)$ needed a way to represent knowledge of the world for a computer interface system they were attempting to build. To do so$,$ they adopted a hierarchical structure model that they called the "semantic network model"; Evidence consistent with this model included that, in general, response times on a sentence verification task increased with increased "path lengths" $($number of steps$)$ within the model. The original Colliins and Quillian Model:

did not account for TYPICALITY

did not account for COGNITIVE ECONOMY

did not account for ENCODING SPECIFICITY

did not account for TRANSFER APPROPRIATE PROCESSING
