Econ. Perspect., 19, 25), how to override it, and its relation to executive functioning. Based on the original bat/ball problem, we designed two additional isomorphic items. In Experiment 1, for four age groups, including 7-, 11-, and 15-year-olds and adults, we determined that the bias is related to the System 1 intervention; the performance in this item was not a matter of mathematical ability and it could be facilitated by changing the order in which the problems were presented. In Experiment 2, we determined that for 15-year-olds, good and bad performances in the item were related to executive functioning, particularly response-distractor inhibition, updating information in working memory, and the regulation of attention; however, subtle differences were identified when the problem was performed in a facilitative context compared with a non-facilitative context. The results indicated that cognitive abilities are a necessary but non-sufficient condition to resolve the problem.esAtribución-NoComercial-SinDerivadas 4.0 Internacional61 Psicologíaartículobat/ball problemcognitive developmentcognitive reflection testexecutive functioning
