Exploratory research was conducted to generate hypotheses regarding behaviors of a 2-year-old subject during social interaction with multi-age partners. The subject of the study was a female child age 2 years and 4 months. Interactions observed were limited to those occurring with a number of partners who were members of the subject's social…

The early acquisition of the interrogative system, with data from Serbo-Croatian, is investigated. The subject is approached from the angle of adult-child interaction. A first-born pair of dizygotic twins were observed, beginning a month prior to the time when they first began to produce questions. (Author/RM)

Describes characteristics of the attachment behavior of 10 infants blind from birth. Behaviors studied were smiling, discriminating tactile behaviors, stranger avoidance and distress, and separation and reunion behaviors. (BRT)

This study was designed to investigate whether depressed mothers would show a predominantly negative affect or fail to provide a positive frame of experience for their babies. Two field studies of depressed mothers and their infants were conducted. A subgroup of 13 subjects and their babies from a larger project conducted in Cambridge…

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:…

Prior to expressing language, infants have mastered many means for engaging in referential communication with others. This contention can be supported by reference to (1) developmental changes in the attentional structure of communication and (2) infants' use of affective expressions as they begin to master referential communication. In an effort…

A longitudinal study was made of women and their first-born children who have different employment and day care experiences during the child's first three years of life. Specific aims of the study were (1) to gain full account of the history and experience of women who return to full-time employment while their first child is still young and of…

Reports an analyses of ratings on Bayley's Infant Behavior Record and test scores from the Bayley Mental Scale for 60 female and 50 male infants at 6, 12, 18 and 24 months of age. Results are discussed in terms of rank-order correlations, behavioral composite scores and study implications. (Author/SDH)

Visual orientation toward a peripheral stimulus by newborns and 7-week-old infants was examined with both a central stimulus present and absent. General conclusion is that, contrary to previous assessments, the neonate appears to exercise internal control over his sampling of the stimulus array rather than being passively captured by it.…

The acquisition of imitative responses without reinforcement was investigated with infants by eliminating contingent reinforcement through the use of videotaped models. Twenty-nine male and female infants were randomly assigned to one of two groups, a Rhythmic Vocalization Group or a Conversation Control Group. Infants in the first group were…

This study compares the face-to-face interaction of infants with fathers to their interaction with mothers and with strangers. Five infants were videotaped in individual interaction with their mothers, fathers, and unfamiliar adults at weekly intervals from the second week until the infants were 6 months old. Infants were seated in a laboratory…

IT IS GENERALLY RECOGNIZED THAT COMPATIBILITY IN ADOPTION DEPENDS ON A SOUND EVALUATION OF THE ADOPTIVE PARENTS AND OF THE INFANT AND THAT THE BEST INTERESTS OF THE CHILD ARE SERVED BY EARLY PLACEMENT IN A PERMANENT HOME. EARLY ASSESSMENT OF THE INFANT, ON WHICH PROPER PLACEMENT IS DEPENDENT, MUST BE PRIMARILY PREDICTIVE. HOWEVER, EXISTING INFANT…

A MAIN PROBLEM ARISING IN THE STUDY OF CATEGORIZING BEHAVIOR IN PRESCHOOL CHILDREN BY MEANS OF SORTING PROCEDURES WAS THAT PERFORMANCE APPEARED TO BE VERY MUCH A FUNCTION OF THE CHILD'S COMPREHENSION OF THE PARTICULAR VERBAL INSTRUCTIONS EMPLOYED BY THE EXPERIMENTER IN PRESENTING THE TASK. THE SPECIFIC AIMS OF THE FIRST STUDY WERE TO INVESTIGATE…

The purpose of this study was to determine the relationship between high risk infants' sensorimotor development and their use of intentional communications. Twenty-six 20-month-old infants, selected at birth by use of High Risk Index, were studied. At 15 months of age each infant was administered five scales from the Uzgiris-Hunt Ordinal Scales of…

This paper reports the effects of one hour of extra post-partum contact between mother and infant on the quality of the attachment observed when the infant was one year old. It was hypothesized that infants in the extra contact condition would be classified as securely attached while regular contact infants would be less frequently classified as…
