Predictive developmental hypotheses play a crucial role in developmental theories. These hypotheses link early developmental behaviors or processes to later developmental outcomes. Empirical tests of predictive developmental hypotheses are generally based on standard regression models. It is argued that hierarchical linear models or longitudinal multilevel models offer a better alternative. A m...

Maternal love, which is at the core of maternal behavior, is essential for the mother–infant attachment relationship and is important for an infant’s development and mental health. In addition, maternal love plays important roles in promoting not only the infant’s resilience, but also the mother’s. Therefore, it is crucial to clarify the neural basis of maternal love and related behaviors to un...

BACKGROUND Although nurse clinicians and researchers use infant behaviors to indicate the responses of preterm infant to stimulation, little is known about how the biological factors of development, sleeping and waking states, infant characteristics, and infant illness severity affect preterm infant behaviors. OBJECTIVE This study examined the development of eight infant behaviors over the pr...

OBJECTIVE This study examined social behaviors related to attachment in children with autistic disorder and the differences in these behaviors from those observed in developmentally disabled children. Additionally, we aimed to investigate the relationship between attachment behaviors and clinical variables, such as age, cognitive development, severity of autism, language development, and mother...

Main and Solomon were the first to create a formal infant Strange Situation classification of attachment disorganization. Bowlby's reflections on the underlying psychological processes of such behaviors, however, began early in his career, including the term "disorganization." Most of these remained unpublished but are available through the John Bowlby Archive. Bowlby saw affective experiences ...

These behaviors are due to undesirable consequences on the social system and even affect personality system, discussed by many scholars and researchers. In this study, the role of family functioning, at...

Genetic variation at a single nucleotide polymorphism (SNP) in the mu-opioid receptor gene (OPRM1) of both humans and rhesus macaques Macaca mulatta has been associated with differential affinity to the endogenous ligand beta-endorphin as well as alterations in pain sensitivity, drug and alcohol dependence, and social behaviors. The new study by Higham et al. (2011) presented in the current iss...

Firstborn children's reactions to mother-infant and father-infant interaction after a sibling's birth were examined in an investigation of 224 families. Triadic observations of parent-infant-sibling interaction were conducted at 1 month after the birth. Parents reported on children's problem behaviors at 1 and 4 months after the birth and completed the Attachment Q-sort before the birth. Latent...

BEHAV. 27(5) 811-817, 1981.--Growth and ingestive behaviors were measured for rats sustaining bilateral olfactory bulbectomies at 1 or 10 days of age. Tests designed to examine nipple-attachment capabilities were accomplished before weaning, and tests designed to examine drinking...

This paper reports on three studies on the development and validation of the Parental Reflective Functioning Questionnaire (PRFQ), a brief, multidimensional self-report measure that assesses parental reflective functioning or mentalizing, that is, the capacity to treat the infant as a psychological agent. Study 1 investigated the factor structure, reliability, and relationships of the PRFQ with...
