“…About a dozen experiments have been published in which red and one of these comparison colors has been presented via printed paper, projected light, a painted wall, a participant number or jersey, or a computer screen; strength has typically been assessed by maximum handgrip force, but occasionally by maximum leg extension force. Both betweenand within-subjects designs have been used with sample sizes ranging from 14 (Hasson, Williams, Gadberry, & Henrich, 1989) to 48 (Ingram & Lieberman, 1985) total participants. Some experiments have found support for the premise that viewing red is linked to enhanced strength relative to blue or green (Dreiskaemper et al, 2013;Elliot & Aarts, 2011;Green et al, 1982;Hasson et al, 1989;O'Connell, Harper, & McAndrew, 1985), but other studies have found no support (Crane, Hensarling, Jung, Sands, & Petrella, 2008;Ingram & Lieberman, 1985;Payen et al, 2011;Rezaeian, Motealleh, & Etemadi, 2015) or mixed support (Dunwoody, 1998).…”
