Background: The present study was designed to investigate the association between visual exploratory behaviour in early infancy, novelty seeking in adolescence, and the dopamine D4 receptor (DRD4) genotype. Methods: Visual attention was measured in 232 three-month-old infants (114 males, 118 females) from a prospective longitudinal study using a…

This set of checklists in separate English- and Spanish-language versions, is designed to help parents and childcare providers determine through observations a child's developmental progress from birth to age 5. The checklists are excerpted from the "Slow and Steady, Get Me Ready" guidebook, written by a retired kindergarten teacher with 25 years…

As part of a longitudinal study of postpartum adjustment and infant development, this study examined whether securely attached 12-month-old infants show greater object mastery motivation and social-object mastery motivation than do insecurely attached infants. Object mastery relates to infants' goal-directed behavior that is oriented toward…

The increase in the number of infants and toddlers experiencing nonparental care creates an urgent need for the insights of theorists, clinicians, and researchers. These insights can help caretakers promote the mental health of infants and toddlers. Although caregivers usually provide sufficient support of babies' cognitive development, they may…

This publication deals with the present crisis in infant/toddler care. It presents information on infant/toddler development and optimal caregiving paractices, citing recent research on appropriate practices and the impact of poor versus quality care. The book is divided into two sections. In the first section, "Development and Program…

This study investigated the contributions of parent, infant, and contextual variables to the prediction of maternal ratings of infant temperament. Between the time when they gave birth and six months after the birth, 104 mothers completed measures of parenting attitudes, maternal anxiety and depression, family social support, demographic…

A newborn child can identify impressions by means of the sense organs with the help of "non-visible" sensory impressions such as tactile and kinesthetic. A communication arises early between different modalities and muscle activities, which make possible an early synchronization, and identity between the infant and its surroundings.…

Maternal and infant behaviors of 30 American and 52 Japanese mother/infant dyads from middle-class homes were compared. The major differences in caretaker behavior were (1) the Japanese mothers spent more time with or in the presence of their babies than did the American mothers, and (2) the American mothers were more active in positioning the…

The primary purpose of this study was to describe the linguistic behavior exhibited by a female subject (age 2 years, 4 months) during naturally occurring social interaction with children of different ages. Verbal and nonverbal behavior were studied; of additional interest were variables influencing the emergence of linguistic behavior. Data were…

This paper briefly reviews studies pertaining to the imitation of facial gestures in early infancy. It is suggested that imitation provides for the initiation of a reciprocal exchange between mother and infant, but does not sustain such an interaction, since this requires a continually varied and changing pattern of gestures. Thus there is an…

This paper discusses a series of three studies investigating the influence of infants' characteristics and signaling behavior on parents. Videotapes of either smiling/cooing/gurgling or crying infants were used to elicit parents' physiological and affective responses. Measured physiological responses included skin conductance, heart rate, and…

SEVERAL STUDIES ON SENSORIMOTOR FUNCTIONS IN INFANTS WERE REPORTED. DAY-TO-DAY OBSERVATIONS WERE MADE OF INSTITUTIONALIZED INFANTS IN AN ATTEMPT TO COLLECT BASELINE DATA ON ADAPTIVE ABILITIES IN CHILDREN. THE EVOLUTION OF FUNDAMENTAL SENSORIMOTOR SKILLS WAS TRACED TO PROVIDE CLUES FOR THE STUDY OF ENVIRONMENTAL EFFECTS ON THE DEVELOPMENTAL…

A study was undertaken on the effects of a specific parent administered infant language stimulation program, beginning at birth, on the longitudinal development of 60 normal first born infants. All infants and their environments were tested in their homes at 6 weeks and at 6 months utilizing the Bayley Scales of Infant Development and the HOME…

The purpose of the present study was to determine whether infants categorized as demonstrating good or poor neuromuscular integrity (voluntary motor abilities reflecting movement coordination) would show differences in use of sensory motor schemas. Subjects were 26 full-term (10 males, 16 females) and 10 premature infants (6 males, 4 females)…

This study examined (1) the level of symbolic capability as revealed in play, (2) the use of spontaneous vocal imitation, and (3) the nature of certain classes of words occurring in spontaneous infant language. Facets of child behavior were examined during the period of single-word utterances and early multiword combinations with a view to…
