Traces encounters between mother and child that occur around nursing and feeding, which result in a powerful attachment. Identifies approaching solid foods and subsequent weaning as the place where detachment begins. Discusses locomotion as another way incremental steps toward independence are reached: crawling, walking, and pulling up with hands…

Four experiments investigating the effects of physical and social variables on the production of pointing in infants 10 to 18 months old are described. In the first two experiments, which were primarily concerned with the relation between reaching and index finger pointing, physical dimensions such as distance between baby and target objects were…

This study was designed to explore the effects of vestibular stimulation on the developmental behavior, respiratory functioning, weight and length gains, and morbidity and mortality rates of premature infants. A total of 20 infants participated in this study in 4 groups of 5 infants each. Group A infants were placed in a motorized hammock within…

This study focused on the identification of specific neonatal temperamental characteristics which may act as early modifiers of mother-infant interaction. Two hypotheses were investigated: (1) certain infant behaviors might be distinguished by the mothers and these characteristics might selectively contribute to the mother's self-image; and (2) an…

This study investigates three types of reciprocal interactions among members of the family unit (father, mother and infant): father-infant interaction affecting child's development, father-infant interaction affecting mother's behavior, and husband-wife interaction affecting mother's behavior. Data from a sample of 39 healthy first-born infants…

This study examined how change occurs in infant gestural communication. Five infants were videotaped once a week from 10 to 12 months and twice a week from 12 to 15 months during play sessions with their mothers in a laboratory playroom. These sessions consisted of 10 minutes of a structured play context in which infants were seated at a table at…

This study investigated pregnant teenagers' knowledge about infant development during the period of their pregnancy. The sample consisted of 98 teenagers between 14 and 19 years old who were pregnant with their first child; all were planning to keep their babies. The group was approximately 50% black and 50% white, 50% middle class and 50% working…

This document presents an analysis of the early attending responses and orienting reactions of infants which can be observed at birth and shortly thereafter. Focus is on one specific orienting reaction, the early direction and maintenance of one's eyes and head toward certain stimuli instead of others. The physical properties of stimuli that…

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 paper offers some ideas on the types of behavior that can be considered precursors to language and that also lay the foundations for logic, mathematics, physics, etc. The paper posits the problem of whether a theory of language must be formulated before one can formulate a theory of language acquisition, or whether the reverse is true. The…

This longitudinal study of 10 infants in a day care nursery traces the development of recognition and attachment to a primary caregiver from approximately 3 1/2 months of age (shortly after enrollment in the program) through the end of the first year. Monthly assessments of about 10 minutes each, on two successive days, were made of the infant's…

This exploratory study investigated whether the Brazelton Neonatal Behavioral Assessment Scale (NBAS) can predict an infant's behavior on mastery motivation tasks at 1 and 2 years of age. Subjects were 31 normal, full-term infants from white, mostly middle class families. Infants were assessed using the NBAS with Kansas Supplements (NBAS-K) at a…

An investigation was made of the behavioral effects of caffeine in a sample of 313 newborns and their mothers. A weighted measure of caffeine based on daily ingestion of coffee, tea, and cola was derived from a maternal interview. The majority of mothers consumed the equivalent of about 1.3 cups of coffee per day. Infant outcome measures included…

This paper describes a series of longitudinal experiments which dealt with the development of object awareness in infants, ages 6-18 months. The experiments were designed to document and evaluate Piaget's account of this development. The studies focused on two types of phenomena: (1) when infants first find an object hidden in one place, they will…

This paper attempts to refute the assumption that early motor development is determined genetically and is not influenced by environmental factors. The paper re-examines three studies which are consistently cited as providing evidence for a maturational theory of motor development: the "early training study" by Gesell and Thompson, the "swaddling…
