Why does degraded video resolution hinder effective co-speech gesture understanding in video conferencing?

💡 Explanation

Degraded resolution reduces the clarity of hand and body movements. Visual iconicity perception, where the form of the gesture resembles its meaning, relies on accurate visual detail; because iconicity is lost, the gesture's contribution to understanding is diminished. Therefore, co-speech gesture understanding is less effective, rather than if only auditory or transcript alignment issues occurred.

• In a distributed database system employing gossip protocols for eventual consistency, why does data entropy (lack of information) decrease more slowly when 'given' data conflicts?
• In a suspense thriller where the protagonist believes they are acting freely, which outcome follows from consistently employing dramatic irony throughout the narrative?
• A subject reads low-frequency sentences, followed by high-frequency sentences; why does saccade length change?
• Why does predictive text on mobile devices sometimes fail to accurately translate 'netspeak' abbreviations?
