Abstract Infants’ smiling is considered an expression of affection, and an index of cognitive and socio-emotional development. Despite research advances in this area, there is much to explore on the ontogeny of smiling, its meaning and the context in which it is manifested early in life. This study aimed at: (a) investigating smiling patterns in these different developmental moments in early infancy, (b) analyzing patterns of association between babies’ smiles and their mothers’ affective… 
Infant Emotion Development and Temperament
Caregivers of young infants are often well practiced in detecting and interpreting the presence or absence of infant emotion. This is particularly true in the case of negative emotions, motivating
Happiness and Joy
Happiness and joy involve feelings of positive engagement which are prototypically expressed through the face, voice, and body. Joyful smiles tend to be strong and involve both eye constriction (the

ABSTRACT This study used an ethological approach to explore the baby-caregiver dyadic exchanges (Attempted interactions, Triggers, Interactions) of nineteen infants during their first weeks in
Bathing routines in different infant placement settings: an ethological study
ABSTRACT This study used an ethological approach to explore the behavioural adaptation of nineteen infants during their first six weeks in Residential Care (RC), or a Foster Family (FF) or an
Disentangling the Dyadic Dance: Theoretical, Methodological and Outcomes Systematic Review of Mother-Infant Dyadic Processes
This work aims at disentangling the different theoretical and methodological definitions of 9 dyadic constructs and highlighting their effects on infants' and children developmental outcomes and provides an original research-grounded framework to consider the different nature of mother-infant dyadic processes within a unified dyadic eco-system.
Video-feedback intervention in mother-baby dyads with depressive symptomatology and relationship difficulties
Post-partum depression (PPD) is one of the most common complications associated to maternal suffering, negative effects for the baby, and difficulties in the relationship. Video-feedback is a
On Laughter of Human Beings: From the Perspectives of Evolution and Social Interaction

Action in Development
Infant motor skill acquisition is so rapid and dramatic that a century of researchers—and eons of parents—have marveled at the scope of developmental change. At birth, infants are essentially

What's in a smile?
This study compared Duchenne and non-Duchenne smiles in early infancy for clues to their emotional significance, suggesting infant smiling does not fit adult models of emotional functioning.
Do Different Infant Smiles Reflect Different Positive Emotions
Different types of infant smiles in the family of positive emotions were investigated during two mother-infant games: peekaboo and tickle. There were 27 6-month-old infants and 28 12-month-olds.
Parental Ethnotheories, Social Practice and the Culture-Specific Development of Social Smiling in Infants
In this article we argue that current theories on socioemotional development during infancy need to be reconceptualized in order to account for cross-cultural variation in caregiver–infant

Developmental changes in the relationship between the infant's attention and emotion during early face-to-face communication: the 2-month transition.
Developmental trajectories for each dyad of the duration of infant facial expressions showed a change from the dominance of Simple Attention to active and emotionally positive forms of attention to the mother toward the end of the 2nd month, supporting an overlapping waves model, rather than a stage model, of developmental change.
Mother-infant interaction during the first 3 months: the emergence of culture-specific contingency patterns.
German and Nso mothers' auditory, proximal, and visual contingent responses to their infants' nondistress vocalizations in postnatal Weeks 4, 6, 8, 10, and 12 suggest culture-specific differences in the modal patterns of contingent responsiveness emerge during the 2nd and 3rd months of life.
What's in a Smile? Maternal Brain Responses to Infant Facial Cues
When first-time mothers see their own infant's face, an extensive brain network seems to be activated, wherein affective and cognitive information may be integrated and directed toward motor/behavioral outputs.
Infant Smiling Dynamics and Perceived Positive Emotion
The findings indicate the potential of automated and fine-grained manual measurements of facial actions to describe the course of emotional expressions over time and to predict perceptions of emotional intensity.
