AI Article Synopsis
- The study focuses on the role of the CRHR1 gene, which is important for hormone regulation in the brain related to stress and emotional responses, particularly in attachment behaviors.
- Researchers analyzed a group of 604 freshmen to see how specific variations (polymorphisms) in the CRHR1 gene might influence the stability and changes in their attachment styles over time.
- The findings indicate that certain variations (rs110402 and rs242924) are linked to stable attachment, but do not affect the variability of attachment styles among individuals.
Article Abstract
Corticotropin-releasing hormone receptor 1 (CRHR1), a hormone receptor essential to the activation of HPA axis and the subsequent release of cortisol, plays critical roles in emotional and behavioral responses relevant to attachment. However, the specific roles of CRHR1 polymorphisms in attachment remain unclear. To further clarify these genetic effects, this research conducted a three-wave study to investigate whether the CRHR1 polymorphisms (i.e., rs110402 and rs242924) are associated with the stability and variability of attachment by using a sample of freshmen (N = 604; M = 18.57 years, SD = 1.90; 68.8% girls). The results showed that rs110402 and rs242924 were associated with the stability of closeness-dependence. The G alleles of the both polymorphisms were found not to be related to lower attachment stability. However, these polymorphisms were not associated with the variability of attachment. Overall, these findings provide evidence for the contribution of CRHR1 to attachment stability.
