The purpose of this study was to determine the impact of infant restraint on dyadic interactions and maternal foraging patterns. Five bonnet macaque (Macaca radiata) mother-infant dyads were observed under three conditions: high foraging demand for the mothers with nonrestrained contact between mothers and infants (HFD-NRC), high foraging demand with restrained contact (HFD-RC), and low foraging demand with restrained contact (LFD-RC). In the restrained contact conditions the infants lived in a nursery within the group pen that allowed dyadic nursing, contact, proximity, and grooming, but prevented the infants from being with their mothers in the remaining portions of the pen, including the foraging area. Observations began when the infants were a mean of 5.4 months old. HFD-RC resulted in decreased dyadic contact relative to HFD-NRC, but did not significantly affect foraging task engagement; there were, however, marked individual differences in the response patterns of the mothers. Dyadic contact was also decreased during the LFD-RC condition, but maternal patterns under low demand resulted in lower levels of infant contact initiation. This study demonstrated the feasibility of a nursery-restrained rearing paradigm in exploring the strategic patterns of coping with conflicting environmental and maternal demands in bonnet macaque mothers. © 1993 Wiley-Liss, Inc.

Relationship with Parents: Attachment01:28

Relationship with Parents: Attachment

Parent-child interactions lay the foundation for how we understand relationships throughout life. These interactions are not uniform across families; instead, they are shaped by a range of environmental, emotional, and behavioral factors unique to each caregiver-child dynamic. Social psychologists study these early relationships to understand how patterns formed in infancy influence social functioning and interpersonal behavior in adulthood.Attachment Theory and Early Relational ModelsJohn...

Attachment01:20

Attachment

Attachment is vital for infant development, as warm social interactions support growth and well-being. In a classic 1958 study by Harry Harlow, the significance of warmth and comfort in forming attachments was examined. Harlow separated newborn monkeys from their mothers and provided two artificial "mothers": one made of cold wire and the other covered in soft cloth. Despite the wire mother offering food, the infant monkeys preferred the comfort of the cloth mother, demonstrating that...

Parental Care00:55

Parental Care

Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.

Relationship Growth01:27

Relationship Growth

Interpersonal relationships progress through stages, beginning with awareness and moving toward mutuality, where emotional connections deepen. While many relationships remain at moderate levels of mutuality, deeper connections form through self-disclosure, trust, and interdependence.Self-DisclosureSelf-disclosure involves revealing personal information, starting with surface-level details and gradually progressing to more intimate content. As trust grows, individuals feel more comfortable...

Close Relationships and Culture

Culture shapes how people approach attraction, choose partners, and build long-term relationships. While some preferences in mate selection appear consistent across cultures, such as men valuing physical attractiveness and women emphasizing financial resources, cultural contexts influence how these preferences are expressed and prioritized. Marriage extends beyond romantic ideals in many societies and is deeply embedded in social, economic, and religious frameworks.The Role of Culture in Mate...

Theory of Romantic Attachment in Adulthood

Attachment is a long-standing connection or bond with others. While Attachment Theory was conceived in developmental psychology to describe infant-caregiver bonding, it's been extended into adulthood to include romantic relationships.
