Ninety‐seven children aged 4–11 (49 males, 48 females, mostly White) were given the opportunity to improve their problem‐solving performance by devising and implementing a novel cognitive offloading strategy. Across two phases, they searched for hidden rewards using maps that were either aligned or misaligned with the search space. In the second ph...
Many animals manipulate their environments in ways that appear to augment cognitive processing. Adult humans show remarkable flexibility in this domain, typically relying on internal cognitive processing when adequate but turning to external support in situations of high internal demand. We use calendars, calculators, navigational aids and other ex...

Among competing perspectives, social accounts suggest that overimitation satisfies social motivations, be they affiliative or normative, whereas the "copy-all/refine-later" account proposes th...
