Type A behavior, 1 of the risk factors for heart disease, is characterized by impatience and competitive achievement striving. An opposing type B pattern is characterized by patience and a lack of competitive achievement striving. Previous observations of mother-child interactions revealed that mothers gave type A and type B children different frequencies of pushing and positive task evaluation. To isolate the effects of type A and B children on caregivers, the present study examined the caregiver behavior of female strangers elicited by boys' type A and B behavior. In addition, it examined whether the child effects differed according to the caregivers' behavior pattern. Results indicated that, relative to type B children, type A children elicited more pushing and positive task evaluation from type B caregivers. However, type A caregivers did not respond to the differences in the children's behavior pattern. The caregiver behavior of type A's and type B's is discussed in light of previous experimental findings of their general responsiveness to variations in their environment.
