Abstract

This study aimed to clarify whether infants and preschool children show susceptibility to contagious yawning, a well-known effect that has been demonstrated experimentally in older children and adults by exposing them to video sequences showing yawns. In a first study, parents kept a log of their child's yawns for a one week period. None of the log entries reported any contagious yawns by the children. Although less frequent than in older children and adults, spontaneous yawning by infants and preschoolers showed the typical morning, post-wakening peak, and an increase before bedtime in the evening. In an experimental study, infants and preschoolers watched a presentation that included many images of yawning and a repeated video clip of their own mother yawning, but there was no evidence of contagious yawning. The results suggest that, even when witnessing yawns by someone with whom they have a strong and positive emotional relationship, very young children do not show contagious yawning.

Imitation, Memory, and the Representation of Persons.

Aimee Moore, Andrew Meltzoff (1994)

Imitation was tested both immediately and after a 24-hr retention interval in 6-week-old infants. The results showed immediate imitation, which replicates past research, and also imitation from memory, which is new. The latter finding implicates recall memory and establishes that 6-week-olds can generate actions on the basis of stored representations. The motor organization involved in imitation was investigated through a microanalysis of the matching response. Results revealed that infants gradually modified their behavior towards more accurate matches over successive trials. It is proposed that early imitation serves a social identity function. Infants are motivated to imitate after a 24-hr delay as a means of clarifying whether the person they see before them is the same one they previously encountered. They use the reenactment of a person's behavior to probe whether this is the same person. In the domain of inanimate objects, infants use physical manipulations (e.g., shaking) to perform this function. Imitation is to understanding people as physical manipulation is to understanding things. Motor imitation, the behavioral reenactment of things people do, is a primitive means of understanding and communicating with people.
