Exploring the perceptual inabilities of Eurasian jays (Garrulus glandarius) using magic effects
Abstract
While we know that humans are often deceived by magic effects, little is known concerning how nonhuman animals perceive these intricate techniques of deception. Here, we tested the susceptibility to be misled by three different magic effects on a sample of six Eurasian jays (Garrulus glandarius). We demonstrate that, similar to humans, Eurasian jays are susceptible to magic effects that utilize fast movements. However, unlike humans, Eurasian jays do not appear to be misled by magic effects that rely on the observer's intrinsic expectations in human object manipulation. Magic effects can provide an insightful methodology to investigate perception and attentional shortcomings in human and nonhuman animals and offer unique opportunities to highlight cognitive constraints in diverse animal minds.
