Dialogical Self Theory, co-regulation, and foundational movement analysis are used to present a description of the development of the dialogical self during the first five months of life using observations of two mother-infant dyads. Susan and her mother illustrate normative emergence of the dialogical self. Susan's I-positions emerge through…

A microgenetic research design with a multiple case study method and a combination of quantitative and qualitative analyses was used to investigate interdyad differences in real-time dynamics and developmental change processes in mother-infant face-to-face communication over the first 3 months of life. Weekly observations of 24 mother-infant dyads…

Different types of smiling varying in amplitude of lip corner retraction were investigated during 2 mother-infant games--peekaboo and tickle--at 6 and 12 months and during normally occurring and perturbed games. Using Facial Action Coding System (FACS), infant smiles were coded as simple (lip corner retraction only), Duchenne (simple plus cheek…

To better understand the form and recognizability of neonatal smiling, 32 newborns (14 girls; M = 25.6 hr) were videorecorded in the behavioral states of alertness, drowsiness, active sleep, and quiet sleep. Baby Facial Action Coding System coding of both lip corner raising (simple or non-Duchenne) and lip corner raising with cheek raising…

This study examined how change occurs in infant gestural communication. Five infants were videotaped once a week from 10 to 12 months and twice a week from 12 to 15 months during play sessions with their mothers in a laboratory playroom. These sessions consisted of 10 minutes of a structured play context in which infants were seated at a table at…

Weekly observations documented developmental changes in mother-infant face-to-face communication between birth and 3 months. Developmental trajectories for each dyad of the duration of infant facial expressions showed a change from the dominance of Simple Attention (without other emotion expressions) to active and emotionally positive forms of…

This study examined the relationship between smile type (basic, Duchenne, duplay) and play type (object, physical, vocal, book reading) during parent-infant videotaped interactions at home. Loglinear analyses revealed that different types of smiles occurred during different types of play more often than expected if distributed equally. Different…

Observed infants' manual gestures while playing with mothers. Infants were more likely than mothers to request objects and less likely to respond to requests for objects. Vocalization accompanying requests increased with age. Infant gazing was most likely during offers that infants initiated without preceding maternal request. Unsolicited offers…

Investigated development of face-to-face communication in infants between 1 and 14 weeks old and their mothers. Found a curvilinear development of early face-to-face communication, with increases occurring between weeks 4 and 9. When placed on a sofa, infants' face-to-face communication was longer than when they were held. Girls spent a longer…

Observed the behavior of 37 infants in response to their mothers' normal and still face. Infants reduced their smiling and increased their gazing away from mother during the still face condition compared to normal face condition. Compared to three month olds, six month olds were more likely to use hand activities while gazing away from mother. (MM)

Observed weekly 13 infants from 1 to 6 months of age to determine when they produced different types of smiling and other facial expressions. Found that the cheek-raise and open-mouth dimensions of smiling appear to be associated with, respectively, amplification of processes of sharing positive affect and of visual engagement present to a lesser…

Reviews research on the developmental roots of nurturance in young children. Examines child characteristics (age, sex); characteristics of the nurtured object (infants and their behaviors); and aspects of the nurturing situation (adult involvement and encouragement). Implications for furture research and child care practices are suggested. (BB)

Compared Duchenne and non-Duchenne smiles of 1- to 6-month olds during weekly videotapes of mother/infant interaction for clues regarding emotional significance. Correlated levels of Duchenne and non-Duchenne smiling within sessions; found that they had similar developmental trajectories. Duchenne smiles were typically preceded by non-Duchenne…

Cites research on smiling and laughter to illustrate a dynamic systems approach to emotion communication. Maintains that emotion is relational and not individual; the nonreflexive aspects of emotion involve the connection between a person and a context taken as a whole. Presents findings regarding social processes involved in smiling and laughter…
