The study investigated the development of children's concepts of autho
rity at home and at school. Subjects (35 m, 35 f) in grades 1-6 were a
sked to evaluate persons issuing two types of commands to children: on
e which resolves a turn-taking dispute and one which Enforces a conven
tional rule. Persons of varying ages and with varying positions in the
family, (parent, older/younger sibling, neighbor! were presented issu
ing commands at home and a parent was presented issuing commands at sc
hool. Results show that children's judgments of authority in the home
are based more on authority position than adult status; younger siblin
gs with delegated authority positions are accepted as authorities by m
ore children than knowledgeable adults without delegated authority. Ch
ildren's authority concepts become increasingly, more differentiated w
ith respect to the social-organizational positions and functions of pe
rsons in authority across grades one to six.
