“…This effect can be explained by the limitation of learners' cognitive resources, especially the capacity of their working memory and attention channels (Sweller, Ayres, & Kalyuga, 2011); furthermore, irrelevant information may interrupt the development of learning‐relevant schemata (for a meta‐review, see Rey, 2012). Many factors can influence the effect, for instance, of arousal (Schneider, Wirzberger, & Rey, 2019) or low attentional inhibition (González, Saux, & Burin, 2019). Even though some researchers showed that decorative pictures impeded learning, these pictures improve learning when learning‐relevant emotions are simultaneously activated or the pictures are integrated into a learning context (Schneider et al, 2016; Schneider, Dyrna, Meier, Beege, & Rey, 2018; Schneider, Nebel, Beege, & Rey, 2018).…”
