Fearful and self-conscious subtypes of shyness have received little attention in
the empirical literature. Study aims included: 1) determining if fearful shyness
predicted self-conscious shyness, 2) describing development of self-conscious
shyness, and 3) examining genetic and environmental contributions to fearful and
self-conscious shyness. Observed self-conscious shyness was examined at 19, 22,
25, and 28 months in same-sex twins (MZ = 102, DZ = 111, missing zygosity = 3
pairs). Self-conscious shyness increased across toddlerhood, but onset was
earlier than predicted by theory. Fearful shyness (observed [6 and 12 months] and
parents' reports [12 and 22 months]) was not predictive of self-conscious
shyness. Independent genetic factors made strong contributions to parent-reported
(but not observed) fearful shyness (additive genetic influence = .69 and .72 at
12 and 22 months, respectively) and self-conscious shyness (additive genetic
influence = .90 for the growth model intercept). Results encourage future
investigation of patterns of change and interrelations in shyness subtypes.
