Background: Postpartum period is associated with higher rates for depression, blues and psychosis. Anxiety is also significant. These disorders may have serious implications in the cognitive development of the infant. There is relative lack of data in this area. So we tried to estimate postpartum anxiety and depression in a group of women and…

We compared the cognitive and language development at 4, 14, 24, 36, 54 months, and 7 years of siblings of children with autism (SIBS-A) to that of siblings of children with typical development (SIBS-TD) using growth curve analyses. At 7 years, 40% of the SIBS-A, compared to 16% of SIBS-TD, were identified with cognitive, language and/or academic…

Evidence indicates that the newborn infant must first develop cognitive systems, through his experience with various stimuli, to differentiate each modality separately before he can integrate any two modalities in classical conditioning. (Author/NH)

Two experiments investigated infants' ability to localize tactile sensations in peripersonal space. Infants aged 10 months (Experiment 1) and 6.5 months (Experiment 2) were presented with vibrotactile stimuli unpredictably to either hand while they adopted either a crossed- or uncrossed-hands posture. At 6.5 months, infants' responses were…

The other-race effect in face processing develops within the first year of life in Caucasian infants. It is currently unknown whether the developmental trajectory observed in Caucasian infants can be extended to other cultures. This is an important issue to investigate because recent findings from cross-cultural psychology have suggested that…

Background: The quality of very preterm infants' spontaneous movements at 11 to 16 weeks post-term age is a powerful predictor of their later neurological status. This study investigated whether early spontaneous movements also have predictive value for the intellectual and behavioural problems that children born very preterm often experience.…

Developmental rates and standard scores are examined for 56 infants in four gestational age groups by repeated measurements on the mental scale of the Bayley Scales of Infant Development. (Author/JMB)

Proposes, as an alternative to Sokolovian models, a model of early habituation based on selective adaptation of feature detectors. The model suggests that early habituation is attributable to the organization and immaturity of the young infant's visual system. (RH)

Maintains author's interpretation of 6-month-olds' behavior is consistent with task requirements in the 2000 study and previous work showing that infants use explanatory inferences to make sense of their world. Asserts that ability to understand that people communicate with persons but act on objects is precursor to infants' understanding at 9 to…

Aim: Very-low-birthweight (VLBW; birthweight less than 1500g and/or gestational age less than 32wks) children are at risk for speech problems. However, there are few studies on speech development in VLBW children at an early age. The aim of this study was to investigate phonological development in 2-year-old VLBW children. Method: Twenty VLBW…

In four experiments, we investigated whether 9-month-old infants are sensitive to the relationship between gaze direction and object location and whether this sensitivity depends on the presence of communicative cues like eye contact. Infants observed a face, which repeatedly shifted its eyes either toward, or away from, unpredictably appearing…

Using data from a longitudinal study of preterms and full-terms, the present study examined the structure of infant cognition at 12 months, the extent to which five 12-month abilities (attention, processing speed, recognition, recall, and representational competence) mediated the relation from prematurity to mental development at 2-3 years, and…

Visual events are defined by a number of dimensions--their location in space, content (color, shape, etc.), and time tags (onset, duration, etc.). The role of time in infants' performance in the Visual Expectation Paradigm (VExP) was studied to evaluate whether infants encode in their expectation representation the timing of events in addition to…

Far from egocentric, infants and toddlers advance significantly in their understanding of others' feelings, desires, goals, intentions, preferences, and views during the first 2 years of life. In so doing, they establish the foundation for later social and emotional understanding. This article surveys those accomplishments, speculates about how…

Mirror neurons are increasingly recognized as a crucial substrate for many developmental processes, including imitation and social learning. Although there has been considerable progress in describing their function and localization in the primate and adult human brain, we still know little about their ontogeny. The idea that mirror neurons result…
