Recent research shows that while initial learning is dependent on "N"-methyl-D-aspartate receptors (NMDArs), relearning can be NMDAr-independent. In the present study we examined whether this switch also occurs following forgetting. The developing animal exhibits much more rapid rates of forgetting than adults, so infant rats were used. It was…

The current study examines the developmental trajectory of banging movements and its implications for tool use development. Twenty (6- to 15-month-old) infants wore reflective markers while banging a handled cube; movements were recorded at 240 Hz. Results indicated that through the second half-year, banging movements undergo developmental changes…

Do infants, like adults, consider both the probability of falling and the severity of a potential fall when deciding whether to cross a bridge? Crawling and walking infants were encouraged to cross bridges varying in width over a small drop-off, a large drop-off, or no drop-off. Bridge width affects the probability of falling, whereas drop-off…

The goal of this study was to examine developmental change in visual attention to dynamic visual and audiovisual stimuli in 3-, 6-, and 9-month-old infants. Infant look duration was measured during exposure to dynamic geometric patterns and Sesame Street video clips under three different stimulus modality conditions: unimodal visual, synchronous…

How do people make rich inferences from such sparse data? Recent research has explored this inferential ability by investigating probabilistic reasoning in infancy. For example, 8- and 11-month-old infants can make inferences from samples to populations and vice versa (Denison & Xu, 2010a; Xu & Denison, 2009; Xu & Garcia, 2008a). The…

Continuous color changes of an array of elements appear to stop changing if the array undergoes a coherent motion. This "silencing" illusion was demonstrated for adults by Suchow and Alvarez ("Current Biology", 2011, vol. 21, pp. 140-143). The current forced-choice preferential looking study examined 4-month-old infants' sensitivity to the…

The Miami Lighthouse, in its 81 years of service to persons who are visually impaired (that is, those who are blind or have low vision), has adapted to meet the ever-changing needs of clients of all ages. To meet the significant needs of visually impaired children--more than 80% of early learning is visual (Blind Babies Foundation, 2012)--the…

The first years of life are witness to rapid changes in long-term recall ability. In the current research we contributed to an explanation of the changes by testing the absolute and relative contributions to long-term recall of encoding and post-encoding processes. Using elicited imitation, we sampled the status of 16-, 20-, and 24-month-old…

The psychic significance of the figure of the grandmother in psychodynamic psychotherapy has received scant attention. This paper develops the concept of the "grandmaternal transference" in parent-infant psychotherapy and explores its identification, its possible functions and its therapeutic significance. The grandmaternal transference has…

"Children's Budget 2019" is a comprehensive analysis of how kids and families have been faring in the federal budget over the past five years. The book captures and analyzes historical funding data and spending trends across a wide range of policy areas including child welfare, early childhood, education, health, housing, income support,…

The author was wholly unprepared for what he encountered when he entered Fraiberg's Child Development Project at the University of Michigan in 1973, joining five others in a special 2-year training program in infant mental health. He sputtered in astonishment. He resisted the interpretations. But there was no turning back, once he was exposed (on…

While studies report associations between perinatal outcomes and both autism spectrum disorder (ASD) and intellectual disability (ID), there has been little study of ASD with versus without co-occurring ID. We compared perinatal risk factors among 7547 children in the 2006-2010 Autism and Developmental Disability Monitoring Network classified as…

Background: Early identification of Autism Spectrum Disorder (ASD) is currently limited by the absence of reliable biological markers for the disorder, as well as the reliability of screening and assessment tools for children aged between 6 and 18 months. Ongoing research has demonstrated the importance of early social communication skills in…

Background: We evaluated early pragmatic language skills in preschool-age siblings of children with autism spectrum disorder (ASD), and examined correspondence between pragmatic language impairments and general language difficulties, autism symptomatology, and clinical outcomes. Methods: Participants were younger siblings of children with ASD…

Differences in vocabulary that children bring with them to school can be traced back to the gestures they produced at the age of 1;2, which, in turn, can be traced back to the gestures their parents produced at the same age (Rowe & Goldin-Meadow, 2009a). We ask here whether child gesture can be experimentally increased and, if so, whether the…
