And will they still engage in problem solving even if it doesn\u2019t lead to a food reward?  We designed a research experiment to find out. <\/p>\n<p>We were startled to discover that raccoons were <a href=\"https:\/\/doi.org\/10.1016\/j.anbehav.2026.123491\" rel=\"nofollow noopener\" target=\"_blank\">intrinsically motivated to solve multiple puzzles within a 20-minute trial<\/a>, even when finding a solution did not directly lead to an irresistible marshmallow.<\/p>\n<p>Innovative brains, like primates<\/p>\n<p>Raccoons often engage in problem-solving when foraging in human-dominated areas, and have several adaptations that allow them to do this. <\/p>\n<p>First, they have a <a href=\"https:\/\/doi.org\/10.3389\/fnana.2017.00118\" rel=\"nofollow noopener\" target=\"_blank\">high number of neurons<\/a> packed into a relatively small brain. Their neuronal density is more similar to that of primates than other carnivores. <\/p>\n<p>They also have <a href=\"https:\/\/doi.org\/10.1016\/S0166-4328(98)00067-9\" rel=\"nofollow noopener\" target=\"_blank\">highly dexterous forepaws<\/a> adapted for foraging in streams, and a generalist diet that allows them to eat nearly everything we throw away. <\/p>\n<p>            <a href=\"https:\/\/images.theconversation.com\/files\/724820\/original\/file-20260318-57-28x7lj.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip\" rel=\"nofollow noopener\" target=\"_blank\"><img decoding=\"async\" alt=\"A raccoon perched on a water fountain, drinking water.\" src=\"https:\/\/www.newsbeep.com\/il\/wp-content\/uploads\/2026\/03\/file-20260318-57-28x7lj.jpg\" class=\"native-lazy\" loading=\"lazy\"  \/><\/a><\/p>\n<p>              Raccoons frequently use human household equipment and technology for their own purposes.<br \/>\n              (Unsplash\/Fr0ggy5)<\/p>\n<p>As researchers, we were curious to discover whether raccoons change their strategies as problems become more difficult. For example, what does a raccoon do if the garbage bin is open, versus if it has a lid or if that lid is locked? <\/p>\n<p>We were also curious whether their problem-solving follows what we call an <a href=\"https:\/\/doi.org\/10.1037\/dec0000033\" rel=\"nofollow noopener\" target=\"_blank\">exploration-exploitation trade-off<\/a>.<\/p>\n<p>An irresistable marshmallow reward<\/p>\n<p>To explore these questions, we gave raccoons a multi-access puzzle box. These boxes are used in animal cognition research to study problem solving and innovation. They have <a href=\"https:\/\/doi.org\/10.4161\/cib.18787\" rel=\"nofollow noopener\" target=\"_blank\">multiple problems to solve<\/a> so the animal can access a single food reward. <\/p>\n<p>Typically, researchers give the animal a multi-access box and let the animal solve a puzzle of their choosing to access the reward. Then, the researcher locks that solution and the animal must innovate a new way into the box. <\/p>\n<p>Instead of locking the solutions on the box we asked a simple question: What would happen if we left the box unlocked and let the raccoons freely interact with it? Would they keep going back to the same solution type that they already knew how to use, or would they explore and open new solution types? <\/p>\n<p>Would they open the box once, get their food reward \u2014 a single marshmallow \u2014 and be done? Or would they keep playing with the box even after the food<br \/>\nreward was gone?<\/p>\n<p>            <img decoding=\"async\" alt=\"A raccoon tries to open a box with turn knobs and padlocks.\" src=\"https:\/\/www.newsbeep.com\/il\/wp-content\/uploads\/2026\/03\/file-20260319-57-7zx2fb.jpeg\" class=\"native-lazy\" loading=\"lazy\"  \/><\/p>\n<p>              A raccoon has successfully opened a turn knob solution on the multi-solution puzzle box and is working on removing an unlocked lock from the hasp latch.<br \/>\n              (Hannah Griebling)<\/p>\n<p>Raccoons solve problems for fun<\/p>\n<p>What the raccoons did was surprising. We expected them to find multiple solutions on the box. We did not expect them to continue looking for solutions after they found the single marshmallow inside the puzzle box. <\/p>\n<p>They seemed to be intrinsically motivated to open multiple solutions within a 20-minute trial, even when solving the puzzle didn\u2019t directly lead to a marshmallow reward. <\/p>\n<p>In fact, the raccoons were discovering multiple solutions on the puzzle box even when the problems got more difficult to solve, and they could see and feel with their forepaws that there wasn\u2019t another marshmallow in the box. <\/p>\n<p>When the going gets tougher<\/p>\n<p>As those problems became more difficult, the raccoons began to quickly hone in on a single solution to keep returning to. <\/p>\n<p>This follows an <a href=\"https:\/\/doi.org\/10.1037\/dec0000033\" rel=\"nofollow noopener\" target=\"_blank\">exploration-exploitation trade off<\/a>, where it\u2019s more beneficial to exploit a single solution when the problems are more difficult, since solving them takes more time and effort from the raccoon. <\/p>\n<p>            <a href=\"https:\/\/images.theconversation.com\/files\/724864\/original\/file-20260319-71-xhookd.jpeg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip\" rel=\"nofollow noopener\" target=\"_blank\"><img decoding=\"async\" alt=\"Racoon stands behind a puzzle box, trying to find a way in.\" src=\"https:\/\/www.newsbeep.com\/il\/wp-content\/uploads\/2026\/03\/file-20260319-71-xhookd.jpeg\" class=\"native-lazy\" loading=\"lazy\"  \/><\/a><\/p>\n<p>              A raccoon works on a medium difficulty solution.<br \/>\n              (Hannah Griebling)<\/p>\n<p>Imagine standing on a city street, feeling hungry.
