OBJECTIVE Normative values for infant sleep architecture have been established exclusively in the solitary sleeping environment. However, most of the world's cultures practice some form of parent-infant cosleeping. In addition, no previous polysomnographic studies in infants examined the frequency of electroencephalogram (EEG) arousals. This is the first study to assess (a) EEG arousals in infa...

The purpose of this study was to investigate the effect of a handicapping condition on mother-infant interactions and, to investigate the conditions under which coordinated attention to an object and a person is demonstrated. This study provides a unique opportunity to make across-mother and within-mother comparisons of mother-infant interactions in two sets of fraternal twins. In each set, one...

The short-term impact of infant exposure to alcohol in breast milk on mother-infant interactions and infant arousal was examined. Fourteen mother-infant dyads were tested on 2 occasions that consisted of an alcohol administration and a nonalcohol condition. Mother-infant interactions during feeding were videotaped and coded for dyadic reciprocity. maternal noncontingency. and dyadic conflict. I...

Parent-offspring birth weight correlations are presented by sex of parent and infant. They range from .14 to .16, except for the mother-daughter correlation, which is .32. This pattern of parent-offspring correlations varies when the parity of the infant, the size of the mother, and the mother's drinking and smoking status are considered. All parent-offspring correlations are higher when the in...

OBJECTIVE This study assessed adolescent maternal psychopathology and its relation to the quality of mother-infant interactions. METHOD Twenty-one mother-infant pairs recruited from an adolescent medicine clinic were assessed for socio-demographic background, psychosocial adversity, conduct disorder, alcohol or substance dependence, and depression. Dyads were videotaped during free play and t...

Abstract Males may increase their fitness by providing care to offspring or unrelated infants of female “friends” maximise future mating. The potential for paternal depends on paternity certainty, particularly in multi-male, multi-female groups with polygynandrous In crested macaques ( Macaca nigra ), there seems be high certainty and need protection. However, male-mother affiliation (or “frien...

BACKGROUND It is clear that early social interaction follows from mother-infant interaction after pregnancy. Many researchers have illuminated this interaction in the first years of life. Most common mother-infant interaction is the attachment behavior of an infant. The Japan Children's Study (JCS) development psychology group hypothesis is that the early mother-infant interaction will predict ...

Background:Infant mortality is often used as a standard measure of a population’s health. Until cause of Sudden Infant Death Syndrome is unknown (SIDS), the best strategy to decrease SIDS, is programming to decrease facing with risk factors. The aim of this study was to find the SIDS risk factors among families during their child care in Iran. The study is the first in Iran to examine the risk ...
