“…Social facilitation of learning has been described for several species ( Bond and Titus, 1983 ; Zion et al, 2007 ; Lipina and Roder, 2013 ; Demolliens et al, 2017 ; Lau et al, 2019 ), including laboratory rats ( Gardner and Engel, 1971 ; Becker and Franks, 1975 ; Varlinskaya and Spear, 2009 ; Gipson et al, 2011 ; Dorfman et al, 2016 ). Hollis and Nowbahari (2013) , Hollis et al (2015) , and Turza et al (2020) investigated conspecific rescue behavior in ants, suggesting that sharing the environment with predators facilitates the expression of these behaviors, although non-rescuer species also seem able to display these. In this study, the presence of a trapped conspecific probably played the role of facilitation.…”
