Focus on some of the problems of culturally different groups is the purpose of this paper; also, some implications are drawn for the adult educator. These problems are basically problems of communication caused by the apartness of these groups from the dominant society. The communication process is defined as involving an exchange of meaning between the sender (Encoder) of a message and the receiver (Decoder). In three studies, researchers set out to identify personality traits common to culturally different groups and to describe relationships between them and the dominant society. Bases of difference include different value systems and attitudes springing from social, economic and other forces operating in the environment. Other impediments to communication arise from differences in language. Some implications of these communication problems for the adult educator are: (1) The adult educator must involve these groups in the program planning process; (2) He must learn to respect the difference in language; and (3) The adult educator must enlist the aid of sophisticated members of the different groups in the planning process of any program.
