“Adults are able to distinguish between choices and are oftentimes more likely to select the first one. This is called primacy bias,” says the study’s lead author, Emily Sumner, a doctoral candidate in cognitive sciences at the University of California, Irvine. “But kids, particularly toddlers under three, who may not know language as well, demonstrate a recency bias when responding to questions verbally, meaning the last choice presented is more often selected. This area hasn’t been studied in children before, so this is fascinating to pinpoint.”
