Three approaches to the study of children's reactions to the unfamiliar are
reviewed with an emphasis on how the approaches differ in terms of measure
ment and interpretation of individual differences. Studies are reviewed whi
ch have particular relevance for the understanding of the role of temperame
nt in predicting children's academic, social, and personal adaptation. Over
all, it appears that differences in children's reactions to the unfamiliar
may be more directly related to social and emotional adjustment than to aca
demic adjustment per se. However, it is hypothesized that differences in ch
ildren's reactions to the unfamiliar may indirectly influence adjustment in
school through their influences on social and emotional adjustment. Sugges
tions are made for school psychologists and educators regarding approaches
for assessment and modifications to the classroom environment to meet the n
eeds of temperamentally diverse students.
