Atypical motor development has frequently been reported in infants at elevated likelihood for autism spectrum disorder. However, no previous study has used detailed motion capture technology to compare infant siblings of children with autism spectrum disorder and infant siblings with no familial history of autism spectrum disorder. We investigated…

This research examined whether infants tested longitudinally at 10, 14, and 16 months of age (N = 58) showed evidence of perceptual narrowing based on face gender (better discrimination of female than male faces) and whether changes in caregiving experience longitudinally predicted changes in infants' discrimination of male faces. To test face…

Saccade latency is widely used across infant psychology to investigate infants' understanding of events. Interpreting particular latency values requires knowledge of standard saccadic RTs, but there is no consensus as to typical values. This study provides standard estimates of infants' (n = 194, ages 9 to 15 months) saccadic RTs under a range of…

The present study examined the role of attentional demand on infants' perseverative behavior in a noncommunicative looking version of an A-not-B task. The research aimed at clarifying age-related improvements in the attention process that presumably underlies the development of cognitive control. In a between-subjects design, forty 10-month-olds…

The purpose of the study was to establish dimensions of functioning accounting for interindividual variation in behavior in the later infancy period and to investigate the stability of the dimensional structure during the infancy period. Factor analyses were performed on parent questionnaire data for 357 infants, aged 11 to 15 months. An 8-factor…

The purpose of this study was to apply factor analysis techniques to delineate dimensions of early infant behavior and to establish categories of functioning which can be seen as a source of individuality in early childhood. Data about the behavior of 791 infants in two age groups (11-25 weeks and 26-41 weeks) were obtained using a questionnaire…

Two parental questionnaires were developed for measurement of temperament in one- and two-year old children in Sweden. (MP)

Compares the behavior of mothers to their own infants at three- to four- and nine- to 10-months of age in five of the societies described in previous chapters: Gusii of Kenya, Yucatec Mayan of Mexico, Italian, Swedish, and suburban Bostonian. Reveals differences between agrarian and urban-industrial societies, as well as culture-specific patterns…

This report represents the first ever attempt to draw a comparative picture of the physical abuse of children in the 27 richest nations of the world. UNICEF research estimates that almost 3,500 children under the age of 15 die from physical abuse and neglect every year in the industrialized world. The greatest risk is among younger children. A…

This special issue of the "Courrier," a journal for professionals concerned with issues related to the physical and psychological development of children, provides (1) an overview of 25 years of internationally coordinated research, (2) a selection of papers published by the research teams, and (3) a description of the teams and their…
