Examines the development of normative sleep-wake state characteristics in full-term infants, and atypical state characteristics as presented in several clinical populations including preterm and autistic children. Reviews and critiques the literature on the usefulness of infant state parameters in predicting developmental outcomes of infants at…

Assessed infants' attachment behaviors toward nonparental adults, including grandparents, other relatives, and family friends. Found that the extent of infants' attachment behavior to nonparental adults was related to infant-mother attachment behavior and to the nonparental adult's responsiveness in teaching and position in the mother's social…

This study established content validity and reliability for the Infant Behavioral Summarized Evaluation, a rating scale for young children with autism. Analysis of videotapes for 89 children (ages 6-48 months) revealed a significant group of 19 items, including characteristic early autistic behaviors and some less commonly described (such as…

Used event-related potentials (ERPs) and fixation duration to examine infants' responses to events. Found that ERPs, but not looking time, distinguished between familiar events presented frequently rather than infrequently, and between familiar and novel events presented infrequently. Proposed that ERPs reflected updating of working memory or…

Infants' orienting of attention undergoes marked development in the first six months of life. Changes in attentional control appear to be related to infants' susceptibility to distress. (Author)

This paper reviews, first, experimental studies of perceptual-cognitive development and related work directed to the assessment of infant intelligence and, second, naturalistic observation of the exploratory patterns of infants during free play. Techniques used, such as the Fagan Test of Infant Intelligence, offer the potential to identify…

Temperament of nine-month olds was assessed by means of questionnaires and two laboratory visits. Mothers' and fathers' agreement on questionnaire scales was low, and their factor structures differed. In laboratory measures, fearfulness and pleasure showed cross-situation generality, short-term stability, and convergence with questionnaire scales.…

This article proposes that intuitive behaviors may be used to detect and resolve potential conflict in mother-infant relationships. Previewing, in which the caregiver introduces the infant to the physical sensations and interpersonal meaning of a new developmental skill, is suggested as a way of moving the mother-infant relationship in the…

Three experiments demonstrated that increasing the length of a mobile serial list impaired 6-month olds' memory for serial order. Findings indicated that the primacy effect was absent on a 24-hour delayed recognition test and was exhibited on a reactivation test, adding to growing evidence that young infants possess two functionally distinct…

Examines the relationship and predictive power of the Early Language Milestone Scale-2 (ELM-2)and the Bayley Scales of Infant Development-II (BSID-II). Both scales were administered to 90 infants at risk for developmental delay due to prematurity and low birth weight. Results of the ELM-2 correlated with BSID-II scores of infants 12 months of age.…

Observed face-to-face interactions between 39 mothers and their first and second-born two-month olds to evaluate within-family differences in maternal affective behavior toward siblings. Found that mothers were more positive with second-borns than firstborns, and second-borns were more positive than firstborns. Siblings' affective behaviors were…

Studied cross-cultural differences using still-face paradigm with 3- to 6-month-old Chinese infants. Found that infants looked and smiled less to both parents' still face; experimental group showed similar still-face effects to both mothers and a stranger. Comparison to archival data from Canadian infants showed that, although Chinese infants took…

Examines evidence that the research community studying infants' object concept and the community concerned with adult object-based attention have been studying the same natural kind. Maintains that the discovery that the object representations of young infants are the same as the object files of mid-level visual cognition has implications for both…

Two experiments used Visual Expectations Procedure to investigate development of expectations in infants up to 12 months old. Reaction time improved and the percentage of anticipations increased between 6 and 9 months using an alternation pattern or a complex pivot pattern, and between 4 and 8 months when using a left-right alternation or a…

Three experiments investigated 4-, 6-, and 8-month-olds' perception of the audible, visible, and combined attributes of bimodally specified syllables. Results suggested that at 4 months, infants attended primarily to the featural information, at 6 months primarily to the asynchrony, and at 8 months to both features independently. (Author/KB)
