Moreover, the trip itself was much rougher and longer. After undergoing another inspection, the African was purchased and had to face lifetime of bondage in an alien environment. He was stripped of identity, given a new name, and he was taught to envision himself and his African heritage as inferior and barbaric. The White master insisted on total obedience and created a situation of utter dependence. He supplied food, clothing, shelter, discipline, and he was in a position to control the slave's friends and mating. The "Sambo" of literature mirrored reality, this life of dependency created infantile characteristics in many of the slaves and taught them to reject their past while adopting the values of their masters. The American slave system, besides exploiting the Africans labor, possessed and violated his person. Three schools of mass behavior have been suggested as explanations: Freudian psychology, the interpersonal theories of Henry Stack Sullivan, and role psychology. Freudian psychology has put total emphases on early childhood experiences and is the least suited for this purpose. It could be argued that the shock procurement and the total detachment from previous life which it achieved both in the concentration camps and in American slavery emptied the super-ego or conscience of its contents. Then, the creation of total dependence which followed could have resulted in infantile regression. This would account for the childlike behavior of both "Sambo" and the camp inmates. The slave master the camp guard, each in his own way, became a father figure, and the respective victims internalized the value system of this symbolic father. The interpersonal school of psychology states that the determining factor in influencing personality development can be found in the estimation and expectation of "significant others." Those responsible for the physical and emotional security of an individual are his "significant others." For a child these are his parents. As he matures, the number of "significant others" in one's experience increases. This permits one to make decisions of one's own and to develop some individuality. However, the child has already internalized the estimations and expectations of his parents, and this tends to shape his personality for rest of his life. Still, acquiring new "significant others" as adult can be important in reshaping the adult personality. Both the American slaves and the camp prisoners were thrust into situations in which they had a new single "significant other." This was a situation similar to that of childhood, and it could have had the same impact in shaping personality. All previous "significant others" had been made insignificant, and, in each case, the estimations and expectations of this new "significant other" became internalized into the personality of the victims.
