The model simulates a laboratory situation in which subjects receive a set of instructions for moving "objects" into (two) relationships with other (fixed) objects, "targets." While instructions are given the targets cannot be accessed, but objects can undergo preliminary movements, to promote memory. Such movements determine a "Strategy." More effective Strategies encode more of the instructions' contents and render final placements more "Accurate." A good Strategy, e.g., might place the objects relative to the target (e.g., aligning the two); a better encodes the relationship as well. Experimental data, collected by N. Bray and colleagues, is related to model predictions, so that, reports for goodness of fit are given for averages of data for Strategy and Accuracy.
USER INPUT: The user chooses a random number for each model run (up to 10 runs at a time).
SYSTEM OUTPUT: Summary Information (which will be stored in a file)
LATER: 1) more input choices (i.e., model parameters); 2) improving verbosity levels; and MOST IMPORTANT 3) providing models for all 3 groups (NOW, the user gets the same answer for all choices.)
