Response Latency
The delay between input and feedback — measured in seconds for human interaction, milliseconds for AI — and the developmental variable the interactive-media literature never measured.
Response latency is the time interval between a user's action and the system's response. In human interaction, latency is measured in seconds — the pause during which a conversational partner considers, formulates, and speaks. In pre-AI interactive media, latency was measured in hundreds of milliseconds — fast relative to a human tutor but slow relative to cognitive processing. In AI conversational tools, latency has compressed to under two seconds for sophisticated responses, and continues to drop. The critical, unresolved question is whether response latency is itself a developmental variable — whether the seconds of waiting between action and feedback constitute formative cognitive exercise or merely dead time. If latency is developmentally inert, AI's zero-latency responsiveness costs nothing. If latency is formative — if the waiting exercises working memory, tolerance of uncertainty, and the sustaining of cognitive engagement without reinforcement — then compressing it removes an input the developing brain needs.
