q3 i3 For instructors, the correlation between self-reported session joy and the class-average mimicry index was clearly positive (r = 0.82, p < 0.001). → Frenzel 2024 q3 i? For students, the correlation between dyad-specific mimicry index and self-reported session joy was not significant (r = -0.033, p = 0.845). → Frenzel 2024 (2)

Evidence¶

Frenzel 2024¶

Frenzel, A. C., Dindar, M., Pekrun, R., Reck, C., & Marx, A. K. G. (2024). Joy is reciprocally transmitted between teachers and students: Evidence on facial mimicry in the classroom. Learning and Instruction, 91, 101896. https://doi.org/10.1016/j.learninstruc.2024.101896

q3 · i3 · associational · r1

Correlational analysis linking instructors' post-session self-reported joy to the class-average mimicry index across 13 instructors. The article reports "r = 0.82, p < 0.001" and notes the correlation held when controlling for instructors' levels of joy expression (partial correlation = 0.70, p = 0.011).

"In contrast, for instructors, the correlation was clearly positive (r = 0.82, p < 0.001), indicating that instructors subjectively experienced teaching as more enjoyable when their own joy expression co-occurred more frequently with their students' joy expression."

Frenzel 2024 (2)¶

Frenzel, A. C., Dindar, M., Pekrun, R., Reck, C., & Marx, A. K. G. (2024). Joy is reciprocally transmitted between teachers and students: Evidence on facial mimicry in the classroom. Learning and Instruction, 91, 101896. https://doi.org/10.1016/j.learninstruc.2024.101896

q3 · i? · associational · r1

Correlational analysis of 69 students nested within instructors, treating self-reported session joy as ordinal. Table 3 reports the student mimicry index correlation as r = -0.033 [CI -0.368; 0.301], p = 0.845, which was not significant; equivalence was not tested.

"For students, we used the dyad-specific mimicry index and their individual self-reported session joy. We considered the nestedness of students within instructors using the command TYPE = COMPLEX in Mplus."

Discussion¶

Related Claims¶

• Instructors' and students' facial expressions of joy cross-recurred substantially above chance during a critical time window of about -2 to +3 seconds relative to instructors' expressions — related
• Facially expressed joy during class correlated positively with post-session self-reported session joy for both students and instructors, though the instructor correlation did not reach significance — related
• Instructor–student joy mimicry was predominantly dyad-specific: only 16.4% of variance in the mimicry index was attributable to instructors — related
• Instructor-led facial joy mimicry predominated: 58% of dyads were instructor-led and the critical lag window's midpoint was around +500 msec after the instructor's expression — related
• Automated facial joy coding showed high sensitivity and specificity against human coding for both instructor and student videos — related
