Step 1: Understanding the Concept:
Sociometry is a quantitative method developed by Jacob L. Moreno to measure, evaluate, and map social relationships and structures within a group.
Step 2: Detailed Explanation:
- In developmental research and educational settings, sociometry is used to study peer groups.
- Children are asked to nominate peers they prefer to play with, work with, or avoid. This data is mapped as a "sociogram" to identify popular children (popular stars), average children, neglected children, and rejected children.
- Sociometry specifically measures peer acceptance, rejection, and overall social networks within a group. It does not measure cognitive intelligence, clinical behavioral issues, or parent-child attachments.
Step 3: Final Answer
The primary application of sociometry in child development is to evaluate relationships with peers.
