abstract：:Day-old chickens trained in pairs on an aversive discrimination task yielded a retention function with two points of reduced retention, at 15 and 55 min after learning. These points of temporary reduction in retention were interpreted as reflecting change-over of recall from three successive phases in memory formation...
