Virtua. simula.ed environments provide multiple wa.s of testing cognitive function a.d eva.ua.ingproblem solving with huma.s （e.g., Woollett et a.. 2009）. The use of such intera.tive technologyha. increa.ingly become a. essentia. pa.t of modern life （e.g., a.tonomously driving vehicles, glo-ba. positioning systems （GPS）, a.d touchscreen computers; Chinn a.d Fa.rlie 2007; Brown 2011）.While ma.y nonhuma. a.ima.s ha.e their own forms of technology, such a. chimpa.zees whocrea.e a.d use tools, in ca.tive a.ima. environments the opportunity to a.tively pa.ticipa.e withintera.tive technology is not often ma.e a.a.la.le. Exceptions ca. be found in some sta.e-of-the-a.t zoos a.d la.ora.ory fa.ilities （e.g., Ma.la.a.a.u a.d Kuha. 2005）. When intera.tive technologyis a.a.la.le, ca.tive a.ima.s often selectively choose to enga.e with it. This enha.ces the a.ima.＇ssense of control over their immedia.e surroundings （e.g., Cla. et a.. 2011; a.kerma. 2012）.
