Examines the motivational or affective message and impact of infants' cries on nonparents, primiparous parents, and multiparous parents. Cries were organized into three levels (difficult, average, easy) by temperament ratings and spectographic analysis. Physiological and self-report responses to audiotapes of infants' cries were obtained from 36…

Purpose of this experiemnt was to systematically investigate the behavioral effects of vertical rocking at different frequencies up to 1.5 Hz. (Authors/CB)

Notes that 4-month olds who show a low threshold to become distressed and motorically aroused to unfamiliar stimuli are more likely than others to become fearful and subdued during early childhood, while infants who show a high arousal threshold are more likely to become bold and sociable. Considers implications for psychopathology and relation…

A total of 14 infants participated in this study of the recovery of visual orienting by crossmodal stimulation when no new visual information was present. The locus of the crossmodal stimulation (auditory stimulation) was discriminable to the subject. Infants in three age groups were tested on three occasions each separated by 30 days. No…

Investigates intersensory interaction between auditory and visual stimulation in newborn infants. Following auditory stimulation, newborns' visual preferences for light patches of different intensity were examined. Results indicate that newborns attend to quantitative variations in stimulation and that these variations reflect both the objective…

In a study of 24 preterm and 24 full-term infants at 8 months, infants who reacted to a novel stimulus with increased vagal tone showed more focused examination and exhibited greater exploratory play range than those whose vagal tone decreased with the stimulus. (LB)

This paper presents a study of the looking and looking away or gaze alternation behavior of both full term and preterm infants in the presence of varying degrees of facial animation. The faces used in the study included, in increasing order of animation, a Raggedy Ann doll's face, a moving and talking doll's face, a mother's less animated face…

This study explored questions concerning the specificity of facial expression of emotions in infants. A sample of 27 infants (nine each at ages 10, 11, and 12 months) were tested in six experimental and six control conditions. Two of the experimental conditions were designed to elicit fear, two happiness, and two surprise. Videotapes of the…

INFANT SCRIBBLING ACTIVITY IS NOT SIMPLY PLAY. IT CONTRIBUTES TO THE DEVELOPMENT OF VISUAL ATTENTION AND PERCEPTION. YET, SCRIBBLING, UNLIKE WRITING IN THE COMMUNICATION SENSE, IS NOT MOTIVATED BY THE DESIRE TO INFORM, NOR TO SET DOWN THOUGHTS AND FEELINGS. THE EXPERIMENTAL HYPOTHESIS OF THIS STUDY WAS THAT THE MOTIVATIONS FOR SCRIBBLING ARE (1)…

The purpose of the observational system presented here is to record the behavioral interactions between infant and mother, focusing on the sequential and contextual features of the social communication patterns accessible through direct home observation of mothers and their 3- to 4-month-old infants. The present system of continuous data recording…

The Perception of Baby Temperament Scales (PBT) were used to elicit parental perceptions of infant temperament, with the results rated for internal consistency and congruence between parents. Data was obtained from 26 families, with both father and mother describing their first-born infants at five months of age. The PBT Scales deal with a range…

This report includes five documents, three on child care research, and two concerning individual differences and discriminative abilities in newborn and young infants. "The Organization of Infant Day Care Environments: Feedback-Produced Improvements in Staff Job Performance" reports on the effectiveness of monitoring procedures as…
