Background. Instructor enthusiasm has been shown to enhance a range of positive student outcomes including recall, but the underlying mechanisms for the favourable effects of teacher enthusiasm are still largely unknown.Aims. We hypothesized that attention paid to the instructor is one mechanism and that the positive effects of enthusiasm will disappear when attention is captured by another task.Samples. In a series of three studies, we involved fourth and fifth graders in listening to texts read aloud with high or low levels of displayed enthusiasm.
Methods.In Study 1, we obtained self-reported and observed behavioural indicators of attention while students were read texts with high versus low enthusiasm. In Study 2, we additionally manipulated attention by comparing a group who performed a concurrent attentional task while listening to the texts read with high or low enthusiasm to a group who only listened to the texts. In Study 3, we compared the attention-catching concurrent task used in Study 2 to a non-attention-catching dual task.Results and Conclusions. Our results confirm that displayed enthusiasm captures attention and that attention partially explains the positive effect of displayed enthusiasm on recall.In psychological literature, enthusiasm has been defined either as the result of a pleasant affective state stemming from experiences of enjoyment and interest (e.g., Burić & Moè, 2020;Frenzel, Goetz, Lüdtke, Pekrun, & Sutton, 2009), or as an effective instructional strategy acted out to support student achievement and interest (see Keller, Hoy, Goetz, &Frenzel, 2016 and Rosenshine, 1970 for reviews). Whatever its origin, enthusiasm gives rise to a pattern of expressive behaviours, suggesting energy, interest, and involvement. We refer to this as 'displayed enthusiasm', which is easily perceptible to others (Keller, Becker, Frenzel, & Taxer, 2018).Enthusiasm has been shown to positively influence a range of student outcomes:
