The "A not B error" refers to a phenomenon observed in developmental psychology where a child, after repeatedly finding a hidden object in one location (A), will continue to search for it in that same location even after observing it being hidden in a different location (B). This error typically occurs in infants around 8 to 12 months old and is thought to reflect the developing understanding of object permanence and memory.
