Results of a study involving 30 infants of 14, 20, or 26 weeks confirm the existence of distinct developmental phases of attention during the visual preference procedure. Findings suggest a refinement of the use of fixation duration as the major dependent variable in the procedure. (RH)

Investigated the distinctiveness and recognizability of taste-elicited facial expressions in 12 newborns two hours of age. Findings demonstrated that newborns differentiate sour and bitter from each other and from salty, and discriminate between sweet and nonsweet. Judges accurately identified newborns' responses to sucrose, but systematically…

The interrater reliability of three interaction scales--the Maternal Behavior Rating Scale, the Rating Scales of Mother-Child Interaction, and the Teaching Skills Inventory--were estimated with four statistical techniques. The estimates varied widely, both within and across the three interaction scales. Suggestions are offered to help researchers…

Actual and theoretical cases are presented in which the Battelle Developmental Inventory was used in infant assessment. Age-related discontinuities reveal that, for children whose chronological age abuts one of the cut-off points between age categories, radically different summary scores can be obtained from one day to the next despite identical…

Evaluates the validity of extrapolating research findings from the Monadic Phases Coding System (MP) to the Maximally Discriminative Facial Movement Coding System by coding videotapes of 12 4-month-old infants engaged in mother-infant interaction. (RJC)

Examined a sample of 177 infants (age 9 through 12 months) with iron deficiency anemia (IDA) from low-income French, African, and North African Muslim families in Paris. Found a higher than normal incidence of otitis media and respiratory diseases such as bronchitis among the infants. Also examined the relationship between infant IDA and child…

Event-related potentials (ERPs) were recorded from infants shown sets of familiar faces presented frequently and infrequently, and a set of novel faces presented infrequently, and correlated with infant emotional behavior and cortisol levels. Found that infants scoring higher on the normative ERP factor were more distressed during parent…

Discusses the term concept and claims that the use of certain strategies to overcome the loss of multiplication facts due to brain damage is evidence of conceptual knowledge and that infants have rudimentary arithmetical knowledge. (MKR)

Provides overview, background, vision, and goals of a report from the Advisory Committee on Services for Families with Infants and Toddlers. Department of Health and Human Services Secretary Donna Shalala pledged to use the guidelines presented to help establish "Early Head Start," a new support and services program for families with…

Three experiments examined whether the perception and retention of feature relations, thought to be critical for object recognition in adults, are evident in early infancy. Three month olds' 24-hour retention was disrupted when features of a 6-item mobile were recombined, indicating that they not only encode feature relations but also remember…

Four experiments investigated conceptual categorization in 7- to 11-month-old infants. Data revealed global differentiation of animals and vehicles, with lack of differentiation of basic level categories within the animal domain, in contrast to data from other studies designed to assess perceptual categorization. Results suggest that infants may…

This study of early word learning focused on the status of object words in early vocabularies. Fourteen children were followed from nine months to two years of age, and monthly vocabulary growth was analyzed. Results indicated that object words represented approximately one-third, on average, of the different words the children learned. (TJQ)

Four studies examined aspects of expressive behavior development in face-to-face mother-infant interactions. Found evidence of the morphological stability of discrete emotion expressions and that young infants respond differentially to positive conditions based on mother's interest and joy expressions and negative conditions based on sadness and…

Event-related brain potentials (ERPs) were recorded from 6-month-old infants with and without Down syndrome presented with a visual recognition memory task. The ERP morphology was the same for both groups. The chronometry of information processing by infants with Down syndrome was similar to or faster than "normal" infants' processing.…

Within a small bounded space, the location of a hidden object can be coded in terms of distance information, general area of hiding, or the boundary of the space. The use of these three coding strategies by infants was examined using a visual search task. Results indicated boundary information and the nature of the change influenced coding of…
