Abstract

INVESTIGATIONS OF SUCCESSIVE ACQUISITIONS AND EXTINCTIONS (SAE) SUGGEST THAT WITH MASSED TRIALS EXTINCTION RATE INCREASES AND WITH SPACED TRIALS IT DECREASES OR REMAINS CONSTANT. BOTH INCREASED AND DECREASED EXTINCTION RATES WERE OBTAINED USING EITHER MASSED OR SPACED TRIALS WITH 30 MALE HOLTZMAN RATS. RATHER THAN BEING RELATED TO INTERTRIAL INTERVAL (ITI), EXTINCTION RATE APPEARS TO BE RELATED TO THE DIFFERENCE BETWEEN 2 ITIS, THAT BETWEEN SUCCESSIVE NONREWARDED TRIALS (ITI-NN) AND THAT BETWEEN LAST NONREWARD OF EXTINCTION AND INITIAL REWARD OF NEXT ACQUISITION SESSION (ITI-NR). AS ITI-NR WAS MADE LONGER OR SHORTER THAN ITI-NN, EXTINCTION RATE INCREASED. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
