N2 - This study explores the relation between variations in the serotonin transporter gene (5-HTTLPR; long vs. short allele), the child's attachment representation (assessed with the Attachment Story Completion Task, reflecting the security of the parent-child relationship), and electrodermal reactivity during a public speaking task, the Trier Social Stress Test for Children (TSST-C) in a sample of 92 7-year-old. Electrodermal reactivity during the TSST-C was not directly associated with variations in 5-HTT However there was a significant gene-environment interaction effect of 5-HTT and attachment security on electrodermal reactivity. Results are interpreted in terms of cumulative protection: Children with a secure attachment representation as well as long 5-HTTa alleles appeared to be less stressed during the TSST-C.
