Is human language an innate biological blueprint or a learned behavior?
In short: This video explores the fundamental mechanics of how children acquire language, tracing the universal stages of development from first babbles to complex speech. It examines the core tension in psychology: whether we are born with a 'hardwired' grammar or learn to speak through environmental reinforcement.
Language development follows four universal stages: cooing and babbling (starting around 2 months), the one-word holophrastic stage (around 12 months), the two-word stage (18-24 months), and telegraphic speech (2-3 years). These milestones occur regardless of a child's specific culture or native tongue.
The debate over how this happens pits B.F. Skinner’s behaviorist view—which emphasizes operant conditioning and reinforcement—against Noam Chomsky’s nativist view. Chomsky proposes an innate 'Language Acquisition Device' and a universal grammar. The video also covers the Critical Period Hypothesis, which suggests an optimal window for learning language before puberty, citing the tragic case of Genie as a primary, though debated, example.
