Age spacing in firstborns and symbiotic dependence
Insights
Firstborns with siblings less than 3 years younger exhibit higher affiliation and succorance needs. This "symbiotic dependence" is linked to the individuation-separation process completion around age 3.
Area of Science:
- Psychology
- Developmental Psychology
- Birth Order Studies
Background:
- Conflicting research exists on the personality traits of firstborns and later-borns.
- The timing of a sibling's birth relative to the firstborn's developmental milestones is crucial.
- The individuation-separation process, typically completed by age 3, is a key factor.
Purpose of the Study:
- To investigate how the age gap between siblings influences firstborns' affiliative and succorance needs.
- To explore the concept of "symbiotic dependence" in relation to birth order and sibling spacing.
- To reconcile conflicting findings in birth order research.
Main Methods:
- Comparative analysis of firstborns (17-19 years old) with varying sibling age gaps.
- Utilized the Edwards Personal Preference Schedule (EPPS) to assess personality traits.
- Compared 32 pairs of firstborns based on sibling proximity.
Main Results:
- Firstborns with siblings under 3 years younger demonstrated significantly higher affiliation needs.
- Firstborns with siblings under 3 years younger showed greater succorance needs.
- Close sibling spacing (less than 3 years) correlated with increased "symbiotic dependence".
Conclusions:
- The age spacing between siblings, particularly the first 3 years of life, significantly impacts firstborns' affiliative and succorance needs.
- "Symbiotic dependence" is a relevant concept for understanding these effects.
- Birth order research must account for sibling proximity to resolve inconsistencies.
Abstract:
Conflicting results concerning the affiliative personality of firstborns and later borns can be explained by considering the importance of the birth of a sibling and the age spacing between the siblings. It is particularly important to determine whether the sibling was born before or after the firstborn was 3 years old, since this age represents the period during which his individuation-separation process is completed. The birth of a sibling before this age would give rise to affiliation and succorance needs, which we propose to consider together under the name of "symbiotic dependence." Comparisons between the responses to the Edwards Personal Preference Schedule given by 32 pairs of firstborns, 17-19 years old, revealed that firstborns having siblings less than 3 years younger show greater affiliation and succorance needs than firstborns not having close siblings.
