Symmetric core-cohesive blockmodel in preschool children's interaction networks

Area of Science:

• Social network analysis
• Developmental psychology
• Sociology

Background:

• Extensive research exists on social mechanisms driving preschool children's network formation.
• Limited focus has been placed on global network structures using blockmodels.
• Previous work suggested mechanisms leading to asymmetric blockmodels but lacked empirical validation.

Purpose of the Study:

• To propose and empirically validate a symmetric core-cohesive blockmodel.
• To investigate the appearance of this blockmodel in preschool children's interactional networks.
• To confirm if common social network mechanisms generate the proposed symmetric blockmodel.

Main Methods:

• Definition of a symmetric core-cohesive blockmodel with distinct group structures.
• Empirical data collection of interactional networks among preschool children.
• Monte Carlo simulations to test network formation mechanisms.

Main Results:

• The proposed symmetric core-cohesive blockmodel was identified in empirical preschooler networks.
• Simulations demonstrated that mutuality, popularity, and transitivity can generate this structure.
• The model's validity was confirmed without considering unit attributes.

Conclusions:

• The symmetric core-cohesive blockmodel is an empirically observable network structure in young children.
• Standard social mechanisms are sufficient to produce this specific global network architecture.
• This research bridges theoretical blockmodeling with empirical social network data in early childhood.
