Retrieval by Accumulating Evidence in an Architecture (RACE/A)
RACE/A is an extension to the ACT-R theory of cognition that models the process of one retrieval from memory. In RACE/A, retrieval of a chunk from declarative memory is thought of as a process in which evidence is accumulated for the likelihood that a chunk will be needed, similar to sequential sampling models of cognitive behavior (e.g., Ratcliff, 1978; Usher & McClelland, 2001). The dynamics of the competition between memory chunks govern the retrieval time from declarative memory. Because RACE/A dynamically updates the activation values of chunks, it can explain interference effects observed in semantic memory retrieval better than existing ACT-R models.
