Results of three experiments support the generalization that early perception of object unity depends on perceived motion, and that the class of effective motions includes, at least, the rigid translations of an object in three-dimensional space. Effective motions may be specified by very different sources of stimulus information. (RH)

Swimming classes that use forced infant submersion may post health hazards, including hyponatremia (infantile water intoxication), intestinal parasites, and dental enamel erosion. (MT)

Two experiments tested whether three- and five-month-old infants could discriminate between upright and inverted versions of point-light displays moving as if attached to the major joints of a walking person. Experiment one investigated discrimination between upright and inverted versions of walker in moving and static displays; experiment two…

Describes a relactation technique mainly based on intense psychological help and counseling, frequent and repeated suctions of the nipple to stimulate the production of prolactin, and complementary feeding to reinforce suction. (RH)

The apparatus described in this paper automatically records and signals criterion head-turns, thereby eliminating errors of judgment or determinations of interobserver reliability. (JH)

Examined speech segmentation in 9-month-old infants, studying phonotactic regularity and prosodic pattern in four experiments involving 96 infants. Discusses implications of the results in light of an integrated multiple-cue approach to speech segmentation in infancy. Contains 92 references. (SLD)

Recent research documents that for infants just beginning to produce words on their own, novel words highlight commonalities among named objects and, in this way, serve as invitations to form categories. The current experiment identifies more precisely the source of this invitation. We asked whether applying a consistent name to a set of distinct…

Symmetry is an important concept in biology, being related to mate selection strategies, health, and survival of species. In human faces, the relevance of left-right symmetry to attractiveness and health is not well understood. We compared the appearance of facial attractiveness, health, and symmetry in three separate experiments. Participants…

A theory of education requires a theory of the mind that is to be educated. Modules are the central feature of the mind of the infant. Innate learning devices, modules, prepare the infant with the following competences: language, number, theory of mind, spatial navigation, music, etc. We propose that the child be taught what evolution has prepared…

Preterm birth is associated with greater difficulty with transitions from childhood to adolescence to adulthood. Adolescents and young adults born preterm have higher rates of cerebral palsy, intellectual disability, cognitive impairment, learning disability, executive dysfunction, attention deficit disorder, and social-emotional difficulties than…

This meta-analysis of 69 studies (1,483 effect sizes) used random effects models to examine maternal employment during infancy/early childhood in relation to 2 major domains of child functioning: achievement and behavior problems. Analyses of studies that spanned 5 decades indicated that, with a few exceptions, early employment was not…

Background: Socially disadvantaged children with academic difficulties at school entry are at increased risk for poor health and psychosocial outcomes. Our objective is to test the possibility that participation in childcare--at the population level--could attenuate the gap in academic readiness and achievement between children with and without a…

An exploratory case study was undertaken to investigate the perspectives and experiences of six early intervention providers as they adopted and implemented a collaborative consultation approach to home visiting in urban neighborhoods. Survey, semistructured interview, and focus group methods were used over a 2-year period to obtain data about…

The increased prevalence of autism spectrum disorder (ASD) and its detection during the first 3 years of life have substantial relevance for early intervention. The purpose of this article is to summarize current scientific and policy information on early identification and early intervention for infants and toddlers with ASD and their families.…
