Although there is much research on infants' ability to orient in space, little is known regarding the information they use to do so. This research uses a rotating room to evaluate the relative contribution of visual and vestibular information to location of a target following bodily rotation. Adults responded precisely on the basis of visual flow…

Pigeons responded in a perceptual categorization task with six different stimuli (shades of gray), three of which were to be classified as "light" or "dark", respectively. Reinforcement probability for correct responses was varied from 0.2 to 0.6 across blocks of sessions and was unequal for correct light and dark responses. Introduction of a new…

Perceptual narrowing--a phenomenon in which perception is broad from birth, but narrows as a function of experience--has previously been tested with primate faces. In the first 6 months of life, infants can discriminate among individual human and monkey faces. Though the ability to discriminate monkey faces is lost after about 9 months, infants…

Bhatt and Quinn (2011) review the substantial evidence that learning constrains perceptual organization in infants. With those findings as a foundation, they discuss five kinds of experiences that engender learning in infants and propose that attention and unitization mediate infant learning. Bhatt and Quinn's article is informative--the ideas…

How do infants use their knowledge of native language sound patterns when learning words? There is ample evidence of infants' precocious acquisition of native language sound structure during the first year of life, but much less evidence concerning how they apply this knowledge to the task of associating sounds with meanings in word learning. To…

Past research has shown that variation in the target objects depicting a given spatial relation disrupts the formation of a category representation for that relation. In the current research, we asked whether changing the orientation of the referent frame depicting the spatial relation would also disrupt the formation of a category representation…

This article describes the role of a Court Appointed Special Advocate (CASA). CASA volunteers are appointed by judges to represent the best interests of children who have been removed from their homes because of abuse or neglect. CASA volunteers are everyday citizens who have undergone screening and training with their local CASA program (National…

The transition to parenthood marks an important developmental stage in adult life, associated with unique challenges to the partners' conflict dialogue in the formation of the family unit. Utilizing a biobehavioral experimental design, we examined the potential positive effects of the infant on the couple's conflict discussion. One…

Theory and evidence suggest the potential value of prodromal intervention for infants at risk of developing autism. We report an initial case series (n = 8) of a parent-mediated, video-aided and interaction-focused intervention with infant siblings of autistic probands, beginning at 8-10 months of age. We outline the theory and evidence base…

In primates and adult humans direct understanding of others' action is provided by mirror mechanisms matching action observation and action execution (e.g. Casile, Caggiano & Ferrari, 2011). Despite the growing body of evidence detailing the existence of these mechanisms in the adult human brain, their origins and early development are…

Although prominent models emphasize that maternal, child, and situational variables are associated with parenting stress, previous research has often neglected to examine associations between maternal and infant temperament characteristics and stress experienced in the parenting role. Additionally, while predictors of global parenting stress have…

The purpose of this study was to compare early speech and language development of children with and without cleft lip and/or palate (CLP) in the US and Slovakia from 6 to 24 months of age. Thirty-two children from the US (eight with CLP and eight noncleft) and Slovakia (eight with CLP and eight noncleft) participated in this study. The children…

Data from 508 Caucasian children in the NICHD Study of Early Child Care and Youth Development shows that the DRD4 (but not 5-HTTLPR) polymorphism moderates the effect of child-care quality (but not quantity or type) on caregiver-reported externalizing problems at 54 months and in kindergarten and teacher-reported social skills at kindergarten and…

Background: Accumulating data from animal and human studies indicate that the prenatal environment plays a significant role in shaping children's neurocognitive development. Clinical, epidemiologic, and basic science research suggests that two experiences relatively common in pregnancy--an unhealthy maternal diet and psychosocial…

Early identification of autism spectrum disorders (ASDs) is facilitated by the use of standardized screening scales that assess the social emotional behaviors associated with ASD. Authors examined accuracy of Brief Infant-Toddler Social and Emotional Assessment (BITSEA) subscales in detecting Modified Checklist for Autism in Toddlers (M-CHAT) risk…
