    "abstract": "A theory of mnemonic expertise is outlined along\nwith findings from initial tests. The expertise belongs\nto a nonnal adult ( D D ) w h o developed a digit-span of\n104 through extended practice. The theory describes\nh o w mechanisms consistent with the principles of\nskilled m e m o r y (Chase & Ericsson, 1982; Ericsson\n& Staszewski, 1989) and identified by analyses of\nDD's behavior, support his skill. Implemented as a\ncomputational model, the theory assumes that distinct\nknowledge structures mediate both DD's encoding of\nshort segments of trial lists as elaborate, well-\nstructured L T M representations and their retrieval in\nseveral recall tasks. Current testing investigates the\nmodel's ability to generate contextual codes, a class of\npatterned m e m o r y elaborations experimentally shown\nto improve DD's serial recall (Staszewski, 1990).\nGiven the same lists D D received, it successfully\ngenerates over 8 0 % of the contextual codes in his\nverbal reports. Because successful simulation of\ncontextual codes entails accurate simulation of\noperations performed by first-order coding\nmechanisms, results support theoretical assumptions\nabout the knowledge underlying DD's coding\noperations. The model's overly powerful coding\nsuggests that more stringent architectural constraint\nmust be incorporated to rigorouslydemonstrate h o w\nskilled m e m o r y can increase working m e m o r y\ncapacity in a normal cognitive architecture and\nsupport expertise.",
