“…Only a few of these experiments have yielded support for a link between viewing red and general physiological arousal (Al-Ayash et al, 2016; Ali, 1972; Deutsch, 1937; Dreiskaemper Strauss, Hagemann, & Büsch, 2013; Shen et al, 1999; Stefanescu-Goanga, 1911; Wilson, 1966). The majority of experiments have found no support (Briki, Rinaldi, Riera, Trong, & Hue, 2015; Brown, 1966; Caldwell & Jones, 1985; Choi, Kim, Kim, Kim, & Choi, 2011; Doust & Melville, 1956; Hatta, Yoshida, Kawakami, & Okamoto, 2002; Kaiser, 1984; Kido, 2000; Kuzinas et al, 2016; Pressey, 1921; Rajae-Joordens, 2011; Sakuragi & Sugiyama, 2011; Seidler, 1995; Wilms & Oberfeld, 2018; Wolfson & Case, 2000; Yoto et al, 2007; Zieliński, 2016) or mixed support (Erwin, Lerner, Wilson, & Wilson, 1961; Jacobs & Hustmyer, 1974; Mikellides, 1990; Schäfer & Kratky, 2006; Schulte-Holierhoek et al, 2017; Ueda et al, 2004). This is the case whether red is compared to blue (which is most common), green (also common), violet, or its own baseline, and regardless of the physiological indicator used.…”
