Social motivation--the psychobiological predisposition for social orienting, seeking social contact, and maintaining social interaction--manifests in early infancy and is hypothesized to be foundational for social communication development in typical and atypical populations. However, the lack of infant social-motivation measures has hindered…

Infants' prelinguistic vocalizations reliably organize vocal turn-taking with social partners, creating opportunities for learning to produce the sound patterns of the ambient language. This social feedback loop supporting early vocal learning is well-documented, but its developmental origins have yet to be addressed. When do infants learn that…

The aim of this study was to determine the effect of sleep quality of postpartum women on perception of insufficient milk and attitude to breastfeeding. The research was designed as a cross-sectional study. It was carried out with 347 mothers in a university hospital between December 2021 and July 2022. Data was collected via a personal…

Frontal asymmetry (FA), the difference in brain activity between the left versus right frontal areas, is thought to reflect approach versus avoidance motivation. This study (2012-2021) used functional near-infrared spectroscopy to investigate if infant (M[subscript age] = 7.63 months; N = 90; n = 48 male; n = 75 White) FA in the dorsolateral…

The ability to perceive approximate numerosity is present in many animal species, and emerges early in human infants. Later in life, it is moderately heritable and associated with mathematical abilities, but the etiology of the Approximate Number System (ANS) and its degree of independence from other cognitive abilities in infancy is unknown.…

Dialogic reading (DR), first described in Whitehurst et al. (1988), is a specific reading technique that encourages parents to involve the child actively in verbal and nonverbal interactions during shared book reading. The well-known acronyms for DR techniques include CROWD (completion, recall, open-ended questions, wh-questions and distancing)…

Cognition research has demonstrated that babies, from birth, can detect numerical correspondences and abstract properties of objects and events. However, this limited existing research is often distant from educational practice, and thus, this information may be inaccessible to early childhood educators; most of whom hold pre-Bachelor level…

Objective: Despite the growing student parent population, many postsecondary institutions in the United States (U.S.) lack sufficient lactation policies for students. The objective of this study was to explore breastfeeding students' perceived awareness and use of on-campus lactation rooms and identify barriers and facilitators to expressing milk…

This study compared the acoustic properties of 26 (100% female, 100% monolingual) Danish caregivers' spontaneous speech addressed to their 11- to 24-month-old infants (infant-directed speech, IDS) and an adult experimenter (adult-directed speech, ADS). The data were collected between 2016 and 2018 in Aarhus, Denmark. Prosodic properties of Danish…

Bilingualism exerts early and pervasive effects on cognition, observable in infancy. Thus far, investigations of infant bilingual cognition have focused on sensitivity to visual memory, executive function, and linguistic sensitivity. Much less research has focused on how bilingualism impacts processing of social cues. The present study sought to…

From their origins, Italian early childhood services paid attention to the transition from family to childcare centre, explicitly referring to attachment theory. In the present study, the "Parent Attachment Diary" was adapted and applied within a childcare centre context to examine the development of infants' relationship with their…

Early mother-infant coordinated interactions play a critical role in infant development. The present study describes the development of the dyadic coordination of vocalization and gaze behavior between mothers and infants over the first year of life. In addition to describing developmental trajectories of behavior, the study contributes to our…

Responses to infant signals are critical to infant development and well-being. However, brain mechanisms underlying paternal responses to infant crying are still largely unknown. Here using EEG, we investigated brain activations in two different groups, 10 fathers and 10 non-fathers, in response to infant-related sounds: typically developing…

The aim of this longitudinal study was to examine the association of infant fussing and crying with self-regulation in toddlerhood and the preschool years, as well as the moderating role of maternal sensitivity therein. When children (n = 149, 53.69% boys) were 6 months old, parents reported on their fussing and crying using a cry diary, and…

In the short span of three years, infants learn to move with confidence and grace, to converse with ease, to investigate and solve problems, and to help others in need--building an exquisite foundation for all learning that follows. Maguire-Fong has updated her groundbreaking book designed to assist pre- and in-service professionals working with…
