Compared to previous generations, young children today hear music that differs not only in its content but also in its source of production, mode of transmission, and integration with other activities or social contexts (Young, 2009). In fact, Young (2009) argues that digital technologies allow the home, as opposed to community sites, to be the…

This study examined changes in infants' performance in detecting tones as a funtion of time. Stimuli were presented in blocks of fixed frequency and intensity, rather than in random order. The findings of earlier studies that an observer can reliably tell from a 1-month-old's behavior when a pure tone is being presented, and that reinforcement of…

Two studies were conducted to examine (1) 1- to 3-day-old infants' imitation of their mothers, and (2) mothers' imitation of their newborn infants. For the infant imitation study, 30 mothers and their infants served as subjects. Two observers stood behind the mother to view the infant's face while the mother presented one of the following…

This study examined mother/child interactions during feedings for full-term, healthy premature, and sick premature newborns. Ten first-born infants in each of these categories were observed with their parents once in the hospital, twice at home, and once in the laboratory during the first 4 months of life. Observations focused on the position in…

Mothers' imitation of their infants during the first 3 days of life is examined in this study. Twenty-four newborn infants (12 males, 12 females) and their mothers participated in the study. On each of the first 3 days following delivery, mother-infant pairs were videotaped in a non-feeding interaction for approximately 5 minutes while the infants…

The main purpose of this paper is to delineate methods of data collection and coding currently being used in a longitudinal observational study of toddlers in 25 black families in Oakland, California. Data collection activities, accomplished through monthly three-hour visits to each home, focused on five types of data: (1) videotaped and…

The study compared maternal and trained observer evaluations of infant temperamental characteristics, to determine how closely the ratings correspond, and to analyze the impact of maternal drug abuse habits on maternal ratings of infant temperament. In relating observer to maternal ratings of infant temperament, seven dimensions were compared:…

Findings from three studies that used a laboratory procedure to assess individual differences in various dimensions of infant temperament in relation to later Brazelton scores are presented. Participants included 59 healthy, full-term and sick, preterm infants. The sick, preterm infants included infants who developed respiratory or neurological…

This study tests the proposition that selective behaviors of both mother and infant during feeding are predictors of weight gain during the first month of life. Forty normal mother-neonate pairs were studied, and the target behaviors were examined using an adaptation of the techniques developed by Brown and Bakeman (in which approximately 60…

This paper reports on a followup study of the long-term effects of infant care patterns among the Logoli people of East Africa. In the original study, 12 infants, ages 7-13 months, were observed to obtain a measure of the frequency with which the infant was held by the mother and others, latency of response to the infant's crying, and the number…

The Mental Development Scales: Birth to Three Years are instruments designed to assess developmental levels of young children within a setting familiar to the child. They (1) provide a greater understanding of child behavior and development, (2) serve as a basis for planning an individualized curriculum for each child, and (3) furnish the means…

Papers and discussants' comments from a symposium on issues concerning infants' reactions to strangers are presented. Researchers agreed that there is a developmental shift in infant behavior at 7 to 9 months of age when the infant becomes more cautious in approaching strangers. However, investigators hypothesize that the presence of the mother,…

This study examines the influence of maternal predispositions toward sex-appropriate behavior and the mother's response to "feminine" or "masculine" cues in infant behavior. In the investigation, one 6-month-old male infant was presented to 11 mothers who served as subjects. The infant was dressed as either boy (blue clothes) and named Adam, or…

In this study an attempt was made to measure variables which were expected to be related to individual differences in infants' social responsiveness toward strangers. The subjects were 48 infants (24 boys and 24 girls) between 8 and 13 months of age. Most were children of Cornell University faculty or graduate students, but a broad range of…

The major objective of this series of studies was to clarify the concept of mastery motivation and to develop measures of this concept applicable to 1-year-old children. Three studies were made with 44 infants, aged 12 to 13 months. The first study, "Aspects of Mastery Motivation and Cognitive Functioning," utilized structured situations…
