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 Infant-Mother Centre (IMC). Direct observations were conducted once a week at bath time. Observed behaviours were: sleep-wake states, visual exploration, motor…

Parents commonly vocalize to infants to mitigate their distress, especially when holding them is not possible. Here we examined the relative efficacy of parents' speech and singing (familiar and unfamiliar songs) in alleviating the distress of 8- and 10-month-old infants (n = 68 per age group). Parent-infant dyads participated in 3 trials of the…

A talking face provides redundant cues on the mouth that might support language learning and highly salient social cues in the eyes. What drives children's looking toward the mouth versus eyes of a talking face? This study reports data from 292 children who viewed faces speaking English, French, and Russian. We investigated the impact of…

Studies on the relationship between bookreading and language development typically lack data about which books are actually read to children. This paper reports on an Internet survey designed to address this data gap. The resulting dataset (the Infant Bookreading Database or IBDb) includes responses from 1,107 caregivers of children aged 0-36…

There is a need to identify children with potential mental health issues early in order to provide "an ounce of prevention." Unfortunately, there are few instruments available to identify emotional and behavioral issues in infants and many never receive intervention. We developed the Brief Child and Family Intake and Outcomes System for…

Early visual deprivation impairs some, but not all, aspects of face perception. We investigated the possible developmental roots of later abnormalities by using a face detection task to test infants treated for bilateral congenital cataract within 1 hour of their first focused visual input. The seven patients were between 5 and 12 weeks old…

Previous studies have demonstrated that various psychosocial risks are associated with poor cognitive functioning in children, and these risks frequently cluster together. In the current longitudinal study, we tested a model in which it was hypothesized that cumulative psychosocial adversity of mothers would have deleterious effects on children's…

The current study aimed to examine infant sleep duration as a moderator of the relations between maternal sensitivity and child externalizing and internalizing symptoms, in a prospective longitudinal design. Fifty-five Caucasian infants (33 girls) took part in 2 assessments, at 1 and 4 years. Maternal sensitivity was rated at 1 year, based on…

Objective: We sought to determine the incidence, clinical features, and demographic profile of head injury secondary to suspected child maltreatment (abuse or neglect) in Canada to help inform the development and evaluation of prevention programs for abusive head injuries. Methods: From March 1, 2005 to February 28, 2008, an average of 2,545…

Psychometric and utility studies on Social Emotional Assessment Measure (SEAM), an innovative tool for assessing and monitoring social-emotional and behavioral development in infants and toddlers with disabilities, were conducted. The Infant and Toddler SEAM intervals were the study focus, using mixed methods, including item response theory…

In this study, new evidence is presented of marked sex differences in the distribution of insecure attachment patterns in middle childhood. Attachment was assessed with the Manchester Child Attachment Story Task (MCAST) in a sample of 122 Italian 7-year-olds. The four-way distribution of attachment patterns was significantly unbalanced, with…

Research has shown a strong connection between birth weight and future outcomes. We ask how health problems after birth affect outcomes using data from public health insurance records for 50,000 children born between 1979 and 1987 in the Canadian province of Manitoba. We compare children to siblings born an average of three years apart. We find…

Temperament was measured at ages four and eight months on a sample of infants representing the five Holingshead social classes. A typology very similar to the New York Longitudinal Study's "easy/difficult" axis was found in both age groups. No influences of social class and gender differences on temperament were found. (CI)

Investigates infants' scanning of two compound stimuli by presenting features (either squares or faces) inside a frame, the frame alone, and features alone. The apparent disappearance of external bias at about 21 months appears to apply to the scanning of only some compound figures. For schematic face figures, no external bias was found.…

A series of studies focused on (1) the evolution of the notion of identity of objects among infants up to 15 months of age and (2) the changing rules by which this development may be understood. Six identity tasks were presented to 60 infants divided into five age groups: 5, 7, 9, 12, and 15 months. Two objects were used in all tasks. In the first…
