The component model of human parenting has been extensively used to study parents' interactions with their offspring and to examine variation across cultural contexts. The current study applies this model to nonhuman primates to investigate which forms of parenting humans share with other primates and how these interactions change over infants'…

The author considers the biological basis of the arts in human evolution, which she holds to be grounded in ethology and interpersonal neurobiology. In the arts, she argues, ordinary reality becomes extraordinary by attention-getting, emotionally salient devices that also appear in ritualized animal behaviors, many kinds of play, and the playful…

Red colobus monkeys are playful primates, making them an important species in which to study animal play. The author examines play behaviors and responses in the species for its play initiation events, age differences in initiating frequency and initiating behavior, and the types of social play that result from specific initiating behaviors. Out…

Recent research suggests that witnessing events of fission (e.g., the splitting of a solid object) impairs human infants', human adults', and non-human primates' object representations. The present studies investigated the reactions of gorillas and orangutans to cohesion violation across different types of fission events implementing a behavioral…

This article presents a tentatively "balanced" view (i.e., midway between lean and rich interpretations) of pointing behavior in infants and apes, based upon the notion of intentional reading of behavior without simultaneous attribution of unobservable mental states. This can account for the complexity of infant pointing without attributing…

Brain damage due to an episode of hypoxia remains a major problem in infants causing deficit in motor and sensory function. Hypoxia leads to neuronal functional failure, cerebral palsy and neuro-developmental delay with characteristic biochemical and molecular alterations resulting in permanent or transitory neurological sequelae or even death.…

Examined the development of pattern recognition in infant pigtailed macaques using the familiarization novelty technique. Results indicate that by at least 200 days postconception subjects show a consistently reliable visual response to novelty. (Author/RH)

Three groups of macaque mother/infant dyads were observed while each lived in ecological settings that differed in level of foraging demand and, hence, the amount of work each mother was required to perform to obtain her daily rations. Findings suggest that in monkeys, as in humans, when mothers are psychologically unavailable to their infants,…

Examines the influence of hormonal factors during pregnancy on maternal responsiveness in infrahuman animals and human beings. Argues that it is likely that maternal behavior in humans has a physiological basis. (PCB)

Four-month-old rhesus monkeys were removed from their social group under three different conditions of perceptual isolation from their mothers and peers. Infant behavior was recorded and blood samples were obtained for analysis of plasma cortisol. Infants never showed signs of depression; their responses following separation were seen as attempts…

Links infrahuman and human research in an examination of sensory and experiential factors that regulate early mothering behavior. (PCB)

Capacity of infant monkeys to mount an antibody response to viral challenge was evaluated after monkeys' removal from their mothers in several social and physical environments. Results indicated that trauma of separation was reduced when infants were familiar with the separation environment or familiar social companions were available. (PCB)

This article outlines a strategy for studying early social relationships in relatively simple animal model systems. It describes some of the differences in approach between neuroscientists and human developmentalists in dealing with the same research problems. (BN)

Discusses ways in which Myron Hofer's work (1987), which draws on studies of rodents and primates, alters the traditional perspective on human attachment. Emphasizes the importance of the component of attachment that does not develop in explaining attachment in the first six months of life. (PCB)

Critically reviews the concept of "bonding," exploring its empirical basis and the implications that follow from its application in practice. Among the conclusions reached are that there is a tendency to oversimplify attachment phenomena and that the notion of a sensitive period for attachment has no direct empirical support. (RH)
