q2 i? In one reviewed study, group silence correlated negatively with performance when only audio data was used, but silence combined with shared-screen activity showed a positive correlation with performance when visual data was added. → Rachelle Esterhazy 2025

q2 · i? · review · r2

The review reports, citing Vrzakova et al. (2020), a study combining visual screen recordings and semantic audio data in remote collaborative problem-solving. "group silence correlates negatively with performance when only audio data is used", while visual data reversed the pattern. No effect sizes are printed.

"The authors find that group silence correlates negatively with performance when only audio data is used. However, when utilizing visual data, silence combined with activity on the shared screen shows a positive correlation with performance."
