Results suggest that the human infant's response to visual stimulation undergoes change during the neonatal period. (Authors)

The relation between maternal presence and infant's vocalization depended upon the infant's state: when the infant was in the active awake state, he vocalized less in the presence of the mother than when alone, thus indicating that the majority of early vocalizations are associated with a non-social situation.

Describes the development of a parent-report to assess infant temperament and presents longitudinal findings. Scales were developed to measure activity level, soothability, fear, distress to limitations, smiling/laughter, and duration of orienting. Longitudinal analyses showed that stability in some scales was age-related. (Author/DB)

Addresses questions about infant perceptual ability and the possibility of its decline as a function of development in the absence of specific experience. Compares English-speaking adults, Hindi-speaking adults, and 7-month-old infants on their ability to discriminate two pairs of natural Hindi (non-English) speech contrasts. (Author/RH)

Focuses on definition of sensitivity, developmental changes in sensitivity, and clinical implications of attachment. Maintains that promptness, consistency, and appropriateness are the main components of sensitivity across parenting dimensions. Suggests that studying infant antecedents to attachment security is equally important to that of parent…

Examined validity of Strange Situation attachment classifications for infants with and without extensive child-care experience and the association of early child-care experience with attachment security. Found that infants were less likely to be secure when low maternal sensitivity was combined with poor quality child care, more than minimal…

Sixty-four mother-infant pairs were videotaped during structured episodes in which the mother challenged the infant to use her instrumentally to get access to or to operate a toy. At age 6 months the infants could use their mothers instrumentally in 36% of the episodes, increasing to 67% at 9 months and 78% at 13 months. (MDM)

Examined the visual scanning patterns of infants ages 6, 10, and 13 weeks who viewed static geometric figures. Measures of fixation dwell-times, saccade lengths, and the choices and sequences of saccadic targets revealed that, although younger infants demonstrated salience-guided scanning behavior, older infants increasingly utilized volitional…

Examined the stress vulnerability of infants with disorganized/disoriented attachment patterns by measuring salivatory cortisol levels in 19-month olds following the Ainsworth Strange Situation procedure. Indicates that infants' disorganized attachment behavior reflects a vulnerability to stressful stimulation, suggesting a model of stress…

Observers used two Q-sorts to describe mothers' and infants' behavior at home. Mothers of more difficult children were less sensitive than other mothers. There was a strong relation between maternal sensitivity and infant attachment. Mothers of more secure infants noticed and enjoyed their babies more than mothers of less secure infants. (BC)

Parents completed the Infant Characteristics Questionnaire (ICQ), and their depression and anxiety were measured, during pregnancy and the postpartum period. The ICQ scores formed two components in the mothers' analysis, and one in the fathers'analysis. Predictors of postpartum ICQ scores were the postpartum ICQ components and the anxiety and…

Evaluated respiratory sinus arrhythmia (RSA) and heart period in 5-month-olds during interaction challenges. Found that during object-mediated challenge, RSA increases were uniquely related to positive engagement. During person-mediated challenge, subjects showed more complex integration of autonomic and behavioral responses such that only infants…

This study was designed to provide a general picture of infant vocal-motor coordination and test predictions generated by Iverson and Thelen's (1999) model of the development of the gesture-speech system. Forty-seven 6- to 9-month-old infants were videotaped with a primary caregiver during rattle and toy play. Results indicated an age-related…

Tested were the impact of rejection and acceptance experienced by adolescent mothers during childhood; social support received after their baby's birth; and infant irritability on angry, punitive maternal behavior. Possible links between maternal behavior and indices of child anger, noncompliance, low confidence, and social withdrawal were also…
