Joint attention (JA) is the purposeful coordination of an individual's focus of attention with that of another and begins to develop within the first year of life. Delayed, or atypically developing, JA is an early behavioural sign of many developmental disabilities and so assessing JA in infancy can improve our understanding of trajectories of…

This study investigated transfer effects of gaze-interactive attention training to more complex social and cognitive skills in infancy. Seventy 9-month-olds were assigned to a training group (n = 35) or an active control group (n = 35). Before, after, and at 6-week follow-up both groups completed an assessment battery assessing transfer to…

The purpose of this study was to replicate and extend previous findings on spontaneous movement and rhythmic engagement with music in infancy. Using the identical stimuli and procedures from the original study, I investigated spontaneous rhythmic movements in response to music, infant-directed speech, and contrasting rhythmic patterns in 30…

Infants imitate others' individual actions, but do they also replicate others' joint activities? To examine whether observing joint action influences infants' initiation of joint action, forty-eight 18-month-old infants observed object demonstrations by 2 models acting together (joint action), 2 models acting individually (individual action), or 1…

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…

Screening studies of a population in primary health care are sparsely reported. The aim was to describe observed atypical behaviours that may be associated with autism spectrum conditions, in a population (n?=?4,329) of infants at eight months. Observations were performed by paediatric nurses. An observational instrument, named SEEK developed for…

This qualitative multicase study explored the process through which three student caregivers engaged in relationships with key infants in the context of an infant practicum course as a foundation for learning about infant development and practice. Focusing on caregiver-infant dyads, data sources included videotaped observations of caregiver-child…

As part of a longitudinal study, infant/toddler pretend play development and maternal play modelling were investigated in dyadic context. A total of 21 children were videotaped in monthly play sessions with their mothers, from age 8 to 17 months. Child and mother pretend play frequencies and levels were measured using Brown's Pretend Play…

Research suggests that early self-regulatory difficulties among high-risk newborns can lead to poor interactional difficulties and negative long-term cognitive and social-emotional outcomes if not identified and treated early. This article describes why an individualized, developmentally supportive, relationship-based program, such as the Newborn…

Self-produced locomotion is regarded as a setting event for other developmental transitions in infancy with important implications for socioemotional development and parent-child interaction. Using an age-held-constant design, this study examined changes in reported infant behaviour and maternal proactive/reactive control and compared them with…

Three children were observed in their homes approximately once a month for one year, from their 11th through 22nd month of life. Based on observation of the children's changing nonverbal behaviors, a five-level developmental sequence documenting the evolution of the cognitive notion of agent was developed. (Author)

The main purpose of this paper is to delineate methods of data collection and coding currently being used in a longitudinal observational study of toddlers in 25 black families in Oakland, California. Data collection activities, accomplished through monthly three-hour visits to each home, focused on five types of data: (1) videotaped and…

Some of the findings of a longitudinal study of three infants between their 11th and 22nd months to document development of linguistic expression of the agent concept indicated that first vocalizations were inconsistently associated with nonverbal agentive behaviors and later mature utterances coded agent-action-recipient events. (MC)

A research project was aimed at measuring the relationship between infant vocalizations and linguistic development and determining the feasibility of using infant vocalizations as a predictor of later psychological and intellectual status. However, a method was needed to analyze the vocalizations of infants. This report describes a method used to…

This study evaluated the effects of completing infant development questionnaires on mothers whose ability to provide an appropriate caregiving environment for their infants was suspect. The 18 mothers who completed the questionnaire were found to be more accurate observers of their infants than 18 control mothers who had not completed the…
