Ultrasonic vocalisations (USVs) emitted by altricial rodent pups are whistle-like sounds with frequencies between 30 and 90 kHz. These signals play an important communicative role in mother-offspring interaction since they elicit in the dam a prompt response concerning caregiving behaviours. Both physical and social parameters modulate the USV emission in ...

Auditory event-related brain potentials (ERPs) were recorded in response to an emotional (a baby's cry) and a neutral (a word) stimulus in a group of mothers 2-5 days after childbirth (n = 20) and in control women (n = 18) who were not in the state of early motherhood. For ...
Wood R M - - 2001
These studies assessed adults' latencies to signal that they would respond to infant crying as functions of (1) the degree of infant distress they perceived in the cry, and (2) contextual information relevant to caregiving. In the first study (N = 34), listeners waited longer to respond to cries that ...
Moore G A - - 2001
This study investigated (a) stability and change in infant affective responses to the still-face interaction, (b) whether maternal depression affected infant responses, and (c) whether responses to the still-face interaction predicted toddler problem behaviors. Infants (63 girls and 66 boys) of European American mothers (67 depressed and 62 nondepressed) were ...

Failure to thrive (FTT) is a syndrome of growth failure that results in an infant who is behaviorally difficult. The current thinking is that FTT results from a problematic infant-mother interaction, with the infant making a significant contribution to the interactional process. It is possible that the behavioral characteristics of ...

Opiate withdrawal behaviors in the infant differ from those of the adult. The neural circuitry underlying opioid withdrawal in the adult rat is well defined and includes the locus coeruleus (LC) and periaqueductal gray (PAG), with a minor role of the amygdala. Because the different behaviors that constitute the infant ...

The administration of sucrose with and without non-nutritive sucking (NNS) has been examined for relieving procedural pain in newborn infants. The calming and pain-relieving effects of sucrose are thought to be mediated by endogenous opioid pathways activated by sweet taste. The orogustatory effects of sucrose have been demonstrated in animal ...

During prenatal development, the central nervous system is transformed from a thin layer of unspecified tissue into a complex system that can process information and organize actions. There are 8 general mechanisms that permit this transformation: neural induction, neurulation, proliferation, migration, axonal outgrowth, synaptogenesis, differentiation, and apoptosis. These processes as ...

BACKGROUND: Management of pain in very low birth weight infants is limited by a lack of empiric knowledge about the multiple determinants of biobehavioral reactivity in infants receiving neonatal intensive care. OBJECTIVE: To examine relationship of early neonatal factors and previous medication exposure to subsequent biobehavioral reactivity to acute pain ...
Gormally S - - 2001
To understand how the 'caregiving context' could affect responses to procedural pain, the authors sought to determine whether (1) the combined effects of sweet taste and holding (caregiving contact) were greater than the effects of either alone, (2) any combined effects were additive or interactive, and (3) the interventions had ...

This study focuses on the early temperamental (TTQ = toddler temperament questionnaire), behavioral (IBR = infant behavior record), and cognitive precursors of impaired language functioning in preschool-age pre-terms infants. The study group consisted of 63 pre-term infants with a mean birth weight of 1246 +/- 437 g born in 1989-1991 ...
Watson J S - - 2001
A theoretical analysis is presented in which the four major attachment patterns (A, B, C, and D) are viewed as adaptations to particular forms of early contingency experience. The author proposes that human infants analyze contingency experience on the basis of two computations of conditional probability, one prospective and one ...
Koós O - - 2001
The authors present a new approach to the etiology of disorganized attachment based on contingency detection theory. According to this view, the relevant common factor in parental maltreatment and unresolved loss that leads to disorganized attachment has to do with the type of "deviant contingency environment" that both of these ...
Stevens B - - 2001
Management of pain for neonates is less than optimal. The administration of sucrose with and without non-nutritive sucking (pacifiers) has been the most frequently studied non-pharmacological intervention for relief of procedural pain in neonates. To determine the efficacy, effect of dose, and safety of sucrose for relieving procedural pain as ...

This study was designed to compare the behavioural pain responses of 2-month-old Canadian-born Chinese babies receiving a routine immunization to those of non-Chinese infants in similar situations. Two groups of 26 infants were obtained from a pediatric clinic held by a Chinese pediatrician and a suburban pediatric practice of a ...
Woodward S A - - 2000
Previously, we proposed a theoretical framework that classified infants into qualitative categories of reactivity, rather than on a continuous dimension. The present research used an objective statistical procedure (maximum covariance analysis, or MAXCOV) to determine if a qualitative latent structure, consistent with our theoretical conjectures, would be found to underlie ...
Clarke-Stewart K A - - 2000
In this study, the authors introduce a new measure of infant temperament, the Pictorial Assessment of Temperament (PAT), and provide information about its psychometric qualities based on findings from a study of 132 mothers and infants. The PAT is a 10-item measure of "difficult" temperament that is quick and easy ...
