Why does the iconicity of gestures decrease during rapid, multi-party conversations?

💡 Explanation

Iconicity relies on cognitive resources to map gestural forms onto meanings. Increased cognitive load in multi-party conversations causes competition for these resources, therefore decreasing gestural iconicity, rather than increasing semantic prediction or sensorimotor synchronization, because those are differently affected by attentional limits.

• A noisy communication channel uses convolutional coding. What happens to the effective channel capacity as the constraint length of the convolutional code increases, assuming a fixed code rate?
• A deep space probe transmits telemetry using 64-QAM. What happens to the information throughput when sporadic solar flares increase background noise substantially?
• Why does semantic satiation occur when someone repeats a word?
• Why does spatial frame of reference significantly impact the perceived temporal sequence of events more for speakers of some languages than others?
• If a language experiences decreased usage in scientific publications and academic discourse, which consequence follows regarding its social status?
• If a poet intentionally violates a consistent iambic pentameter with a spondee in an English sonnet, which consequence is most likely?
