Object Permanence In The Dwarf Goat (Capra Aegagrus Hircus): Perseveration Errors And The Tracking Of Complex Movements Of Hidden Objects, Christian Nawroth, Eberhard Von Borell, Jan Langbein
Christian Nawroth, PhD
Object permanence is the notion that objects continue to exist even when they are out of an observer’s sight. In mammals, the highest stage of object permanence (Stage 6) has been observed only in primates, whereas other species have shown difficulty in following once-hidden objects, particularly when complex movements are involved. We conducted four experiments to examine the ability of dwarf goats to mentally represent once-hidden objects. In Experiment 1, we investigated whether dwarf goats are prone to commit the A-not-B or perseveration error which is commonly used as a measure for self-control. Subjects here continue to search for an …
