The present study examined whether students' prior knowledge moderated the effects of their motivation compositions on learning performance (ie, retention and transfer) and interaction (ie, interpersonal brain synchronization (IBS) and behavioural pattern) in learning from video lectures. The results confirmed the benefits of the composition of two high motivation students on their knowledge transfer. The results also showed that students' prior knowledge had a moderating effect on interaction. For low prior knowledge students, high motivation composition increased their IBS in the temporoparietal junction‐inferior parietal lobule (TPJ‐IPL), temporoparietal junction‐supplementary motor area (TPJ‐SMA), inferior parietal lobule‐supplementary motor area (IPL‐SMA) and anterior prefrontal‐anterior prefrontal cortex (aPFC‐aPFC) regions during co‐explaining and enhanced their regulating‐related behavioural sequences and decreased disagree‐related behavioural sequences. However, for high prior knowledge students, a high motivation dyad composition decreased their IBS in the supramarginal gyrus‐anterior prefrontal cortex (SMG‐aPFC) while co‐viewing the video lecture, and in the TPJ‐IPL, TPJ‐SMA, IPL‐SMA and SMG‐aPFC during co‐explaining, cognitive communication, argumentation‐related and regulating‐related behavioural sequences but enhanced off‐task‐related behavioural sequences. Our findings suggest that instructors should encourage high motivation students to co‐view video lectures, and scaffold students with low prior knowledge to enhance regulating‐related behavioural sequences and scaffold students with high prior knowledge and high motivation to enhance cognitive communication, argumentation‐related and regulating‐related behavioural sequences and decrease off‐task‐related behavioural sequences. Practitioner notesWhat is already known about this topic Co‐viewing video lectures is a common form of learning across a wide range of ages and topics. Students' motivation is essential for optimal learning in various settings (eg, face‐to‐face classroom and online learning). Students' prior knowledge moderates the effects of their motivations on learning from video lectures from the individual perspective. What this paper adds The composition of two high motivation students benefits their knowledge transfer. For low prior knowledge students, the composition of two high motivation students increased their IBS in the TPJ‐IPL, TPJ‐SMA, IPL‐SMA and aPFC‐aPFC regions, enhanced their regulating‐related behavioural sequences and decreased their disagree‐related behavioural sequences. For high prior knowledge students, the composition of two high motivation students decreased their IBS in multiple brain regions, as well as their cognitive communication, argumentation‐related and regulating‐related behavioural sequences, but enhanced their off‐task‐related behavioural sequences. Implications for practice and/or policy High motivation students are encouraged to co‐view video lectures. Instructors should scaffold students with low prior knowledge to enhance regulating‐related behavioural sequences. Instructors should scaffold students with high prior knowledge and high motivation to enhance cognitive communication, argumentation‐related and regulating‐related behavioural sequences and decrease off‐task‐related behavioural sequences.

The enfacement illusion refers to the illusory perception that features of another face that moves in synchrony with one's own facial movements become part of one's own body. Here, we tested whether males whose facial movements are synchronized with a virtual female face exhibit a less pronounced implicit gender-science stereotype than males whose movements are not synchronized. Results show that illusory ownership and agency of the face with opposite gender was successfully induced, and that synchrony significantly reduced the implicit gender-science stereotype as compared with nonsynchrony. Our findings are in line with previous demonstrations about being synchronized with other individuals facilitates feature migration-that is, the integration of their features into one's self-representation.
