The coping characteristics of a large sample of disabled and nondisabled children under three years old are assessed across three categories of behavioral patterns: sensorimotor organization, reactive behavior, and self-initiated behavior. The influence of family income, gender, age, and ethnicity are examined and the implications for early intervention discussed.
