Maternal beliefs about children's social behavior may be important contribu
tors to socialization and development, but little is known about how such b
eliefs form. Transactional models suggest that children's characteristics m
ay influence parents. At 2 years of age, the shy and aggressive behaviors o
f 65 toddlers (28 females) were observed during interactions with an unfami
liar peer; as well, mothers described the extent to which they advocated pr
otective and authoritarian childrearing attitudes. These variables were use
d to predict mothers emotions, attributions, parenting goals, and socializa
tion strategies in response to vignettes depicting aggressive and withdrawn
child behaviors 2 years later. Most child effects were moderated by matern
al attitudes or gender effects. Authoritarian mothers of aggressive toddler
s were most likely to report high control and anger, to blame their childre
n for aggression, and to focus on obtaining compliance rather than teaching
skills to their children. Protective mothers reported that they would use
warmth and involvement to comfort withdrawn children, especially their daug
hters.
