DIRECTED FORGETTING IN PIGEONS RESULTING FROM THE REALLOCATION OF MEMORY-MAINTAINING PROCESSES ON FORGET-CUE TRIALS

When procedural artifacts are controlled, it has been difficult to dem onstrate directed forgetting in pigeons. However, previous research wi th pigeons has not allowed for the reallocation of working memory (fro m forget items to remember items) on forget-cued trials as is possible in human directed forgetting experiments. In the present experiment, directed forgetting was found while controlling for procedural artifac ts and allowing the pigeons to reallocate memory resources on forget t rials. The results indicate that under these conditions, pigeons have active control over memory processing.
