“…In addition to interindividual variations in facial affect sensitivity, differences may be seen within the same individual over time. Factors that have been shown to affect facial affect sensitivity include cognitive load (Patterson & Stockbridge, 1998; Tracy & Robins, 2008), mood congruence (Niedenthal, Brauer, Halberstadt, & Innes-Ker, 2001; Niedenthal, Halberstadt, Margolin, & Innes-Ker, 2000), the use of benzodiazepine medication (Blair & Curran, 1999; Coupland, Singh, Sustrik, Ting, & Blair, 2003; Zangara, Blair, & Curran, 2002), and even the use of Botox (Havas, Glenberg, Gutowski, Lucarelli, & Davidson, 2010). Additionally, individuals may display varied sensitivities to different emotions (Adolphs, 2002; Sprengelmeyer, Rausch, Eysel, & Przuntek, 1998) and in different situations.…”
