The present work examines imitation of mouth opening and tongue protrusion in 32 full-terminfants at three different occasions: When the infants are two to three days, three weeks. andthree months old. The analysis focuses (1) on individual differences in imitative behaviourand (2) on how to operationalize the infants' responses. The overall group analysis revealedthat imitation of tongue protrusion was statistically significant for both two- to three-day-oldand three-week-old infants but not when the children had become three months old. Nostatistically significant effect was observed for imitation of mouth opening. Two differentimitation indexes were constructed in order to assess individual differences in early imitativebehaviour. Results show that short-term stability in imitative tendencies cxists between thefirst and second observation. The results further reveal that methodological factors must beseriously considered when studying neonatal imitation: the overall imitation found for tongueprotrusion is demonstrated to be dependent on how the infants' responses are coded.
