Behavioral research has shown that 12- but not 9-month-olds imitate an unusual and inefficient action (turning on a lamp with one's forehead) more when the model's hands are free. Rational-imitation accounts suggest that infants evaluate actions based on the rationality principle, that is, they expect people to choose efficient means to achieve a…

The elicited imitation task (EIT), in which language learners listen to a series of spoken sentences and repeat each one verbatim, is a commonly used measure of language proficiency in second language acquisition research. The "TOEFL® Essentials"™ test includes an EIT as a holistic measure of speaking proficiency, referred to as the…

Studies investigating imitation are usually conducted with adult models in Western contexts; therefore, the influence of cultural context and the model's age on infants' imitation is largely unknown. This study assessed deferred imitation in 9-month-old infants from the German middle-class ("N" = 44) and the ethnic group of Nso in rural…

This study investigates the role of perception and sensory motor learning on speech production in L2. Compared to natural language learning, acoustic input in formal adult instruction is deprived of multiple sensory motor cues and lacks the imitation component. Consequently, it is possible that inaccurate pronunciation results from training.…
