“…In particular, if the advantage of interest-based text preference during learning is that it only helps the learner to manage the potential negative influence of difficulty (Renninger, Ewen, & Lasher, 2002), then engagement and learning will be equivalent for preferred, easy texts and preferred, difficult texts. However, if there is an added advantage of interest-based text preference for engagement and learning (Fulmer & Frijters, 2011), such that it inspires greater attention, concentration, and deeper processing, we expect that participants will report higher engagement and demonstrate greater learning for difficult texts, compared with easy texts. Based on our operationalization of engagement, this higher engagement will be reflected in more positive-activating affect (positive valence and moderate arousal), less mind wandering, and greater reading time for the difficult compared with the easy texts.…”
