Mapping number words to approximate magnitudes: associative learning or structure mapping?


How do we link number words to the magnitudes they represent? We investigated the roles of associative learning and structure mapping in linking the Approximate Number System to number words. Four tasks demonstrated that individuals have strong associative links between magnitudes and number words for relatively small sets, but have weak associative links for larger sets. These results point to multiple mechanisms for the mapping of number words to magnitudes.
