This study examined the differential effects of sex of parent, sex of child, and sex of stranger on infant behavior in a stranger-separation situation. Year-old infants (16 males and 19 females) from middle-class families were observed and videotaped twice, at one-week intervals, in a modification of Ainsworth's laboratory stranger and separation…

An exploration of the clinical usefulness of the Brazelton Neonatal Behavioral Scale was made. A specific pediatric problem was studied, i.e., a baby born to a heroin-addicted mother taking methadone. The control sample was a population of 41 babies who were part of a larger study. Both methadone and control infants were tested between 48 and 72…

Presents a developmental study of changes in infant attachment behaviors. Five groups of female infants, 8, 11, 14, 19, and 24 months of age, were observed during varying types of separation experiences. Changes in proximity behaviors and contact behaviors were analyzed. (BD)

Selected vocal and gestural imitation items were presented to twenty-four 8-, 14- and 20-month-old boys and girls in an elicited task situation. Both vocal and gestural imitation increased with age, although for each age group there was significantly more gestural than vocal imitation. (BD)

Using the Ainsworth Strange Situation Procedure, a study examined the interrelations between dimensions of emotion and social interactive behaviors to explore the regulatory role of each in mother-infant interaction and how these roles may change in the second year. (HOD)

The Carolina Record of Infant Behavior was used to assess the stability from 3 months to 1 year of such characteristics as activity level, irritability, and social responsiveness in 39 preterm infants at risk for developmental disorders. The most stability was observed on such developmentally based items as social orientation. (Author/JW)

The responses of 18 Down's syndrome infants in a modified "strange" situation were recorded. The results indicated that these infants were aware of the exits and entrances of both mother and stranger. (Author)

Sixty infants (ages 11 to 26 weeks) were divided into 3 groups (healthy, preterm healthy, and preterm sick). Ten minutes of infant-parent interaction were videotaped, and mothers viewed the tapes and identified infant behaviors they interpreted. Differences in behavioral interpretations among mothers are identified, as are correlations among…

The booklet provides background information on the diagnosis and characteristics of autism. A chart portrays the signs and symptoms, followed by the definition of the syndrome by the National Society For Children and Adults with Autism. Associated features are noted along with information on age of onset, etiology, incidence and sex ratio,…

The influence of age, sex, representational detail of objects (prototypicality) and adult play suggestions on children's progression of pretend behaviors was studied. A checklist was developed and utilized for coding the responses of 20 children (10 males, 10 females), to objects judged to be high and low prototypical by 12 adults. Children ranged…

This paper presents arguments for greater use of sophisticated research strategies and statistical analyses of data in dealing with the real-life complexity of social interaction. Three possible procedures are proposed and illustrated in a study of interactions between mothers and their 8- to 18-month-old children. The first strategy is to…

Theories and descriptions of various infant fear behaviors are presented in this paper. Five examples of fear are given: (1) learned fear, in which the infant associates some unpleasant action with an agent, (2) unlearned fear, in which the infant experiences an intense sensory phenomena such as a loud noise, (3) stranger anxiety, (4) fear caused…

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…

Examines the validity of a maternal rating scale for pacifier-attachment in a laboratory setting. Once mothers' abilities to assess their children's attachment behavior were ascertained, a second study was designed to contrast the patterns of attachment to pacifiers, blankets, and hard objects in children between 1.5 and 63 months.
