As a basis for this research program, Morrison and Goldberg 1982 presented a model of the memory structure which underlies procedural task performance. The model assumed that memory for a procedure is hierarchically organized around task goals. In the present study, this model was tested by a proximity analysis of soldiers recall. Proximity analysis is based on the assumption that items grouped together in memory tend to cluster together at recall. To perform this analysis, estimates of temporal or ordinal proximity are obtained on an item-by-item basis. The proximities are then subjected to a hierarchical cluster analysis, the result being a graphical representation of memory structure. This technique was applied to the verbal recall and hands-on performance of armor procedures. It was predicted that soldier responses would cluster about discernible goals.
