title: Object permanence in cats: Analysis in locomotor space.
abstract: Stages IV and V object permanence were studied with 38-40-week-old cats. A constraining apparatus preventing animals from pursuing the bowl containing meat before it was concealed was used. Either the bowl was seen moving and disappeared from view behind a screen (stage IV trials), or after this sequence, it reappeared from behind the first screen and disappeared behind a second screen (stage V trials). In both situations cats performed significantly above chance but the paths taken to reach the food were different according to the stage. In stage V trials, cats expressed a preference for the path leading to the end of the second screen where the food was last seen disappearing.
