“…Valence (positive/pleasant vs negative/unpleasant) has been regularly included as a rating characteristic for words, pictures, symbols, and icons (Ito, Cacioppo, & Lang, 1998;Libkuman et al, 2007;Moors et al, 2013;Prada et al, 2015;Rodrigues et al, 2018;Söderholm et al, 2013;Warriner et al, 2013). The precise role of valence in determining user performance is unclear, but it is widely implicated in cognition including perception, working memory, and semantic activation (Angrilli et al, 1997;Galindo et al, 2015;Montoya et al, 2017;Pauligk et al, 2019;Storbeck & Clore, 2007;Warrington & Shallice, 1984;Yamaguchi & Chen, 2018;Zdrazilova & Pexman, 2013).…”
