... The validity of these cardiovascular markers has been supported by dozens of studies, which assessed or manipulated challenge/threat states in various ways (e.g., Moore, Vine, Wilson, & Freeman, 2012; Moore, Vine, Wilson, & Freeman, 2014;Moore, Wilson, Vine, Coussens, & Freeman, 2013;Scheepers, de Wit, Ellemers, & Sassenberg, 2012;Shimizu, Seery, Weisbuch, & Lupien, 2011;Tomaka, Blascovich, Kelsey, & Leitten, 1993;Tomaka, Blascovich, Kibler, & Ernst, 1997;Turner, Jones, Sheffield, Barker, & Coffee, 2014;Weisbuch-Remington, Mendes, Seery, & Blascovich, 2005; for reviews, see Blascovich, 2008;Seery, 2013). Not only has past work directly manipulated resource-demand evaluations to examine cardiovascular markers of challenge/threat (Moore et al., 2012O'Connor, Arnold, & Maurizio, 2010), but correlational studies have examined these associations using self-report resource-demand pre-task evaluations (Moore, Young, Freeman, & Sarkar, 2018;Tomaka et al., 1993;Tomaka et al., 1997;Turner et al., 2013;Vine, Freeman, Moore, Chandra-Ramanan, & Wilson, 2013;Zanstra, Johnston, & Rasbash, 2010). Past work has also assessed or manipulated other psychological constructs that should affect resources-demand evaluations, including self-esteem, social anxiety, task framing, and social power (e.g., Scheepers et al., 2012;Shimizu et al., 2011;Seery, Blascovich, Weisbuch, & Vick, 2004;Weisbuch-Remington et al., 2005). ...
