Relevant exploration.
Proportion of relevant exploration time devoted to the honey extraction, corrected for total exploration duration of apparatus. Sumatran females spent more time exploring the relevant parts of the problem solving apparatus than Bornean and males showed less relevant exploration time than females (LM: NSumatra = 19, NBorneo = 13, Pspecies = 0.064, βspecies = 0.139 ± 0.072, Page = 0.210, Psex = 0.029, βsex = −0.183 ± 0.080).
