14. The method as set forth in claim 13 , wherein the links are represented as weight values, and wherein weight values are updated based on the activation levels of the linked items.

15. The method as set forth in claim 13 , wherein recall is a function of the activation level of each item, wherein an item is considered recalled if its activation level rises above the other activations going on at the same time.

16. A computer program product for memory improvement intervention, the computer program product comprising:

computer-readable instructions stored on a non-transitory computer-readable medium that are executable by a computer having one or more processors for causing the processor to perform operations of:
