This manual provides information on preventive treatment and improving the health and food of infants, young children, and their mothers in developing nations. The nutrition needs of women during and following pregnancy are outlined, as well as the benefits and problems of breast feeding and weaning techniques. A discussion is presented on the…

THE PURPOSE OF THIS STUDY WAS TO FIND OUT WHETHER SOCIAL CLASS DIFFERENCES IN INTELLECTUAL DEVELOPMENT ARE PRESENT IF (1) CHILDREN FROM SOCIALLY DISORGANIZED SLUM FAMILIES ARE COMPARED WITH CHILDREN FROM STABLE, LOW INCOME AND MIDDLE INCOME FAMILIES, (2) THE PIAGET OBJECT SCALE, A NEW MEASURE OF COGNITIVE DEVELOPMENT BASED ON PIAGET'S SENSORIMOTOR…

A research project was aimed at measuring the relationship between infant vocalizations and linguistic development and determining the feasibility of using infant vocalizations as a predictor of later psychological and intellectual status. However, a method was needed to analyze the vocalizations of infants. This report describes a method used to…

In order to determine if infants possessed contingency awareness and if it were related to a temporal unit, two hypotheses were constructed. (1) Reinforcement of a response would probably lead to emission of that response only if the infant's next response occurred within a period of time during which he could remember the preceding…

This study used the behavioral contrast paradigm to assess the excitatory and inhibitory capabilities of young infants. Behavioral contrast is described as the phenomenon whereby the rates of responding in the presence of two stimuli, both of which were previously associated with reinforcement, change in opposite directions when only one of them…

This study examined the reactions of 45, 10-month-old infants to peer strangers. The infants were observed in two conditions: with a stranger of the identical age (10 months) and with one who was younger (5 months). In additon, each infant's behavior when he was alone with his mother was compared to his behavior when he was in the presence of…

This paper reports a study which investigated 2-month-old infants' auditory discrimination of tone quality in the male voice, extending a previous study which found that voice quality changes (soft versus harsh) in a female voice were discriminable by infants at this age. Subjects were 20 infants, tested at 8 and 9 weeks of age. Each infant was…

This bibliography contains over 1400 references on child development, assessment, and intervention. References pertain to any condition that might be expected to interfere with a child's normal progress in school; the age range of concern is birth to five years. The entries are categorized into seven groups: (1) the development and use of…

This interim report is part of a longitudinal study of developmental behavior designed to determine whether infants from culturally disadvantaged homes have different developmental patterns than infants from advantaged homes. Twenty six culturally disadvantaged infants were individually evaluated on the Bayley Scale of Infant Mental and Motor…

A program of infant home visiting was established in Denmark as a result of concern about the rate of infant mortality. The objectives, problems, and promise of the infant Home Visiting Program are summarized and evaluated in terms of their implications for the United States. Although the results of the program have been overwhelmingly favorable…

A total of 48 8- to 14-week-old infants were presented with a non-contingently moving visual stimulus and the infants' visual attention was measured. Infants who exhibited decrements in attention to the non-contingent stimulus showed recovery in attention when the same stimulus was made to move contingent upon a motor response. Moreover, wisual…

A study was conducted to measure the degree to which groups of infants could generalize color across objects of different forms and sizes and generalize from across objects of different color and sizes and to see whether color or form would dominate in their generalizations. Ss were 8-13-month-old Caucasian infants. All tests had 16 Ss except the…

Presents a study of the early home experiences of a group of 2-week-old infants, equally divided according to social class, birth order and sex. (JMB)

Presents a study of decalage between object permanence and person permanence. Decalage was influenced by environmental as well as stimulus factors with infants tested between 6- and 81/4-months/of-age. (BD)

The extent to which two trained observers agreed in coding infant communicative cues was examined in a study of 15 mothers and their 11-month-old infants whose handicaps ranged from mild to severe. Observers agreed on the occurrence of an infant cue less often when coding their more severely handicapped infants. (Author/JW)
