A new protocol for investigating visual two-choice discrimination learning in lizards

Abstract: One of the most widely studied abilities in lizards is discrimination learning. The protocols used to test lizards are often novel or adapted from other taxa without proper validation. We need to ensure that tests of discrimination learning are appropriate and properly applied in lizards so that robust inferences can be made about cognitive ability. Here, we present a new protocol for testing lizard discrimination learning that incorporates a target training procedure, uses many daily trials for efficiency and… Show more

“…This lower difficulty may have decreased the lizard’s motivation to change strategy and improve (Ashwood et al, 2022). We also observed that lizards discriminated between different types of prey (in line with reports of complex visual processing abilities (Qi et al, 2018; Szabo et al, 2018; Szabo and Whiting, 2022)), and preferred those found in their regular diet (Figure 4L). However, lizards also performed strikes on novel prey that they did not encounter before (Figure 4L) suggesting lizards can balance between novel and familiar prey choices.…”
