Abstract excerpt

Anxious temperament (AT) is a nonhuman primate phenotype that models childhood behavioral inhibition, a prominent risk factor for anxiety disorders and stress-related psychopathology. To understand its earliest antecedents, we characterized AT's developmental trajectory over the first year of life. Infant monkeys (n = 35, 24 females) were longitudinally phenotyped for AT by assessing threat-related increases in...
