It\u2019s what enables a skittering squirrel, for example, to quickly ascertain which tree offers the most acorns, or a late-to-work motorist to figure out which E-Z Pass lane will get him on his way fastest. Scientists believe we are all born with this ability, and it probably is an evolutionary adaptation that permitted our human and animal ancestors to survive in the wild.<\/p>\n<p>In the study, everyday folks logged onto a website to play a simple game that tested their intuitive number sense by asking them to view screens displaying varying numbers of yellow or blue dots, and deciding rapidly which were more plentiful. (Readers can take the test themselves by logging onto www.panamath.com.) The test subjects also reported in detail about how they did in math class throughout their school years, and on the math portion of the SAT.<\/p>\n<p>Previous research links school math ability with number sense in teenagers, but this study demonstrates that relationship holds fast throughout the lifespan. Halberda and his team, however, were surprised to find that <strong>number sense peaks around the age of 30 \u2013 almost a decade after other cognitive abilities reach their most acute<\/strong>.<\/p>\n<p>\u201cPerhaps most striking to us were the <strong>large developmental improvements that we found in people\u2019s gut number sense precision \u2013 improvements that continued into the thirties<\/strong>,\u201d he said. \u201cEither the\u00a0 maturing brain or the everyday activities people engage in helped improve the precision of their number sense throughout the first three decades of life.\u201d<\/p>\n<p>These results suggest that <strong>a person\u2019s number sense is not set in stone<\/strong>, Halberda says, <strong>and may be improved by the things we do daily<\/strong>, such as deciding which grocery store check-out line has the fewest shoppers, or which airport security line will get us on our way most quickly.<\/p>\n<p>The fact that some people seem to be born with \u2013 or develop \u2013 more acute number sense than others also has important implications educationally. The finding that number sense is, in a sense, malleable leaves open the possibility of developing educational strategies to improve people\u2019s number sense, Halberda says.<\/p>\n<p>This study was funded by the National Science Foundation and the Eunice Kennedy Shriver National Institute of Child Health and Human Development.<\/p>\n<p>&nbsp;<\/p><\/blockquote>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>From the Johns Hopkins University press release: A first-of-its kind study using the World Wide Web to collect data from more than 10,000 study subjects ages 11 to 85 found&#8230; <a class=\"read-more-link\" href=\"https:\/\/therapytoronto.ca\/news\/2012\/06\/study-examines-how-number-sense-evolves-over-lifespan\/\">Read more &raquo;<\/a><!-- AddThis Advanced Settings generic via filter on get_the_excerpt --><!-- AddThis Share Buttons generic via filter on get_the_excerpt --><\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[6],"tags":[18,19,12,124],"_links":{"self":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/4160"}],"collection":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/comments?post=4160"}],"version-history":[{"count":3,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/4160\/revisions"}],"predecessor-version":[{"id":4163,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/4160\/revisions\/4163"}],"wp:attachment":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/media?parent=4160"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/categories?post=4160"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/tags?post=4160"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
