The objectives were to characterize behavioral signs of autism spectrum disorder (ASD) in younger siblings of diagnosed children (high-risk; HR) and examine classification features of the Autism Observation Scale for Infants (AOSI). Participants (501 HR and 180 low-risk [LR]) were assessed between 6 and 18 months using the AOSI and at age 3 for…

This study examined whether a novel parent-report questionnaire, the Autism Parent Screen for Infants, could differentiate infants subsequently diagnosed with autism spectrum disorder from a high-risk cohort (siblings of children diagnosed with autism spectrum disorder (n = 66)) from high-risk and low-risk comparison infants (no family history of…

Case study research methodology was used to describe the play behaviors of three infants at 12 months of age, who were later diagnosed with an autism spectrum disorder. Data included standardized test scores, and analyses of video footage of semi-structured play sessions from infants identified as high risk for autism, because of having a sibling…

In this study designed to compare the relative pacifying properties of horizontal and vertical rocking, 13 infants (mean age--58 days) were each tested on two subsequent days. The rocking device was a cradle that could be manipulated to produce side-to-side rocking similar to a commercial cradle or up-and-down rocking. In its up-and-down mode, the…

A total of 192 high-risk infants and 85 full-term healthy newborn infants were administered the Bayley Scales of Infant Development. A principal component analysis was performed separately for the high-risk and control infants. Results suggest that the high-risk infant is similar to the normal infant in behavioral development, especially when…

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…

This study compared three ways of analyzing individual mother-infant attachment behaviors in order to test the hypothesis that success in the search for stable individual differences in attachment behavior is in part a function of the level at which behavior individuality is assessed. Fifty infants were videotaped in the Ainsworth and Wittig…

This study of five month olds compared global maternal opinion with reports on direct observation by mothers and observers. A common set of behaviors thought to index temperament was evaluated. Observers recorded infant behaviors on two home visits. Mother-observer agreement for assessments based on home visits was significant. (SH)

This study established content validity and reliability for the Infant Behavioral Summarized Evaluation, a rating scale for young children with autism. Analysis of videotapes for 89 children (ages 6-48 months) revealed a significant group of 19 items, including characteristic early autistic behaviors and some less commonly described (such as…

Despite previous research indicating that early negative child behavior and the quality of parent-child relationships are predictive of later externalizing problems, few investigators have attempted to trace these antecedents back to infancy. In a sample of 100 infants from low-income families, infant persistence and maternal responsiveness were…

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…

This paper discusses issues connected with the reliability of the Neonatal Behavioral Assessment Scale (NBAS) in terms of behavior prediction, neonatal behavioral organization and stability, and consequent implications for study of newborns. Discussion focuses on: (1) reliability, and (2) prediction and neonatal assessment. The NBAS is seen as a…

In this study, twenty 3-day-old Caucasian neonates were observed before and during feeding in an attempt to demonstrate that individual characteristics of infants, such as alertness and social behaviors, are related to the interaction of mothers and infants during feeding situations. Ten of the infants were males, 10 were females; approximately 70…

This paper describes a cross cultural study of face to face interactions between American and Gusii mothers and their infants. Observations of the Gusii people of Western Kenya suggest that the direct expression of intense affect is de-emphasized through an avoidance of direct face to face interactions. The present study investigated (1) how and…
