“…Thirdly, the type of tasks differs, spanning classical search tasks (e.g., Tuch et al, 2009; Van Schaik & Ling, 2009), creative tasks (e.g., Bonnardel, Piolat & Le Bigot, 2011) or learning tasks (e.g., Heidig, Müller & Reichelt, 2015; Miller, 2011; Um et al, 2012). Fourth, the existing studies have been conducted with a variety of different products and interfaces for example ATM applications (e.g., Tractinsky, Katz & Ikar, 2000), Browser-based applications and websites (e.g., Douneva, Haines & Thielsch, 2015; Douneva, Jaron & Thielsch, 2016; Katz, 2010; Ling & van Schaik, 2006; Van Schaik & Ling, 2009), software (e.g., Reinecke & Bernstein, 2011), mobile phones (e.g., Quinn & Tran, 2010; Sauer & Sonderegger, 2011; Sonderegger & Sauer, 2010; Sonderegger et al, 2014), or portable digital audio players (e.g., Minge & Thüring, 2018; Thüring & Mahlke, 2007). Despite these many different starting-points, possibilities of manipulation, and perspectives, a systematic pattern of whether and how aesthetics impacts performance has not appeared yet and systematic research on proposed theories is lacking (Thielsch & Niesenhaus, 2017).…”
