“…As a final consideration, we would like to focus on the major role of Violation of expectations which emerged in both studies. In a totally different context, i.e., a cognitive analysis of the reasoning mechanisms underlying problem solving and humor, it has been demonstrated that contrast is key to any exploration of alternative strategies in insight problem solving (Branchini et al, 2015 , 2016 ), as well as in inductive (Gale and Ball, 2012 ) and deductive thinking (Augustinova, 2008 ), and it has also been argued that contrast is fundamental to the incongruity mechanism in humor (Colston, 2002 ; Canestrari and Bianchi, 2012 , in press ; Canestrari et al, 2017 ; see reviews in Keith-Spiegel, 1972 ; Martin, 2007 ; Larkin-Galiñanes, 2017 ). The results discussed in the present paper (in particular with respect to the Violation of expectations) suggest that contrast also represents a link between insight problem solving and humor in terms of the cognitive emotions triggering pleasures of the mind.…”
