The appropriate-for-gestational-age (AGA) and small-for-gestational-age (SGA) infants from 30 pairs of full-term and 15 pairs of preterm same-sex twins were compared for neonatal temperament. The evaluation of neonatal temperament included ratings of irritability, resistance to soothing, activity level, reactivity, and reinforcement value. Results…

Noting that accidents are the leading cause of death among infants and children today, this book provides comprehensive guideline for preparing a safe home and caregiving environment for children from birth to around 3 years of age. Following an introduction, the chapters are organized by rooms of a house, with topics listed alphabetically within…

A total of 32 3-month-old infants were carried by their mothers in a soft infant carrier designed to place the infants facing either inward or outward. A within-subject comparison found that when infants were carried facing in, they spent significantly more time sleeping, while infants carried facing out were more active. (MDM)

Reports that, even though young infants can discriminate among different facial expressions, there are individual differences in infants' expressivity and ability to produce and discriminate facial expressions. (PCB)

Investigated emotional responses to the still-face paradigm in preterm and full-term black infants. Preterm infants spent less time than full-term infants displaying big smiles in one episode, and showed a less pronounced decrease in big smiles in a second episode. Results confirm the robustness of the still-face paradigm. (HTH)

Examined the effect of maternal soothing to infant inoculation as well as everyday distress on infant cortisol and behavioral responses to stress in two samples of infants between 2 and 6 months of age. Found no evidence that maternal soothing reduced cortisol or behavioral-stress responses, despite evidence for cross-time stability and…

Babies thrive on security. In early months, secure feelings stem from being warm, cuddled closely, and comfortable in their tummies (and in having clean bottoms!). In this article, the author discusses how to soothe infants and toddlers. The strategies to help ease babies' distress are described. Some of the recommended strategies include: (1) to…

Forty infants (mean age 5 months) of depressed mothers and non-depressed mothers were seated in an infant seat and were exposed to four different degrees of animation, including a still-face Raggedy Ann doll (about two-feet tall suspended in front of the infant), the same doll in an animated state talking and head-nodding, an imitative mother and…

When their infants were 6 months of age, mothers were assessed for self-efficacy (low, moderate, and high illusory control) and knowledge of infant development to determine their impact on mothers' behavioral sensitivity and affect during a feeding task at 9 months (N=70). Mothers' sensory sensitivity to digital images of infants' negative and…

Human adults are more accurate at discriminating faces from their own race than faces from another race. This "other-race effect" (ORE) has been characterized as a reflection of face processing specialization arising from differential experience with own-race faces. We examined whether 3.5-month-old infants exhibit ORE using morphed faces on which…

The A-not-B task is a marker task for infant development where an infant searches for an object being hidden twice, in two consecutive places. In two studies N = 70 infants plus 40 controls were tested in this task using two separate, infant-sized tables. In the first study, the separate tables were joined in front of the infant to form one area.…

This paper considers first the concepts of temperament and emotion and then describes some of the genetic and neurochemical correlates of varied temperamental biases and their contribution to emotions. This discussion is followed by a detailed description of the infant temperamental biases called high- and low-reactive to unfamiliarity and their…

Robots and humans receive partial, fragmentary hints about the world's state through their respective sensors. These hints--tiny patches of light intensity, frequency components of sound, etc.--are far removed from the world of objects which we feel and perceive so effortlessly around us. The study of infant development and the construction of…

The aim of this study was to investigate developmental changes in heart rate response to repeated low-intensity (85 dB) sound stimulation in fetuses between 32 and 37 weeks of gestation. We measured amplitude changes in heart rate as our index of fetal response. At 35 to 37 weeks of gestation, the majority of fetuses showed a deceleratory response…

The aim of the present study was to investigate the influence of maternal modeling on the acquisition of fear and avoidance towards fear-relevant and fear-irrelevant, novel stimuli in a sample of 71 toddlers. Children were shown a rubber snake or spider (fear-relevant objects) and a rubber mushroom or flower (fear-irrelevant objects), which were…
