Attachment01:20

Attachment

300
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...

Theory of Romantic Attachment in Adulthood03:34

Theory of Romantic Attachment in Adulthood

47.5K
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.

Relationship with Parents: Attachment01:28

Relationship with Parents: Attachment

111
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...

Attachment Styles01:24

Attachment Styles

92
Jeffrey Simpson's attachment theory suggests that early caregiver relationships shape lasting patterns of behavior and emotional regulation, known as attachment styles. These patterns are organized along two key dimensions: self-esteem and interpersonal trust. The intersection of these dimensions produces four primary attachment styles that typically persist throughout life and significantly influence how individuals form and maintain relationships.Secure Attachment StyleIndividuals with a...

Piaget's Stage 1 of Cognitive Development01:14

Piaget's Stage 1 of Cognitive Development

1.2K
The sensorimotor stage, the initial phase of Jean Piaget's theory of cognitive development, spans the first two years of a child's life. During this period, infants actively engage with their surroundings, building cognitive awareness through direct interaction with the world. This interaction is primarily based on sensory perception and motor actions, allowing infants to gradually understand basic physical properties and predict how objects interact within their environment.

Socioemotional Development during Infancy01:30

Socioemotional Development during Infancy

244
Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Child Psychiatry

Background:

  • Attachment security, established in early childhood, reflects internal relationship models.
  • The striatum is crucial for attachment behaviors, reward processing, and approach behaviors.
  • Previous research on striatal roles in attachment differences has limitations, especially in intrinsic brain connectivity of typically developing children.

Purpose of the Study:

  • To investigate the association between attachment security and striatal functional connectivity in typically developing children.
  • To explore how inter-individual differences in attachment security relate to brain connectivity patterns.

Main Methods:

  • Resting-state functional magnetic resonance imaging (fMRI) was employed.
  • The study included 68 nine-year-old children (39 secure, 29 insecure attachment).
  • Striatal functional connectivity was analyzed in relation to attachment security.

Main Results:

  • Securely attached children showed increased functional connectivity in the temporo-limbic region compared to insecurely attached children.
  • Child-reported attachment security scores correlated negatively with caudate-prefrontal connectivity.
  • Attachment security scores correlated positively with putamen-visual area connectivity.

Conclusions:

  • Inter-individual differences in attachment security are observable in the functional connectivity organization of the striatum.
  • Findings highlight the striatum's role in the neural underpinnings of childhood attachment security.
  • This study provides insights into the neurobiological basis of attachment in typical brain development.
