“…For example, Zoo Atlanta's research program focuses on studying a breadth of cognitive skills in gorillas and orangutans (Diamond et al, ; Tarou, Kuhar, Adcock, Bloomsmith, & Maple, ), whereas Marwell Zoo's Macaque Cognition Project focuses its work primarily on the function of social communication in its multiple macaque species ( Macaca spp. ; Micheletta, Whitehouse, Parr, & Waller, ; Waller, Peirce, Mitchell, & Micheletta, ; Whitehouse et al, , ). There has also been growth in more applied science in zoos using touchscreens, with researchers exploring welfare implications of cognitive testing (Tarou et al, ; Wagner et al, ), preferences (Hopper et al, in press; Perdue, ), personality (Altschul, Wallace, Sonnweber, Tomonaga, & Weiss, ), and mood (Allritz et al, ; Cronin et al, ; Kret, Jaasma, Bionda, & Wijnen, ) in several species.…”
