This document consists of seven research proposals for studies undertaken by the Child Development and Research Center at the University of Texas at Austin for 1967-68. Each of the proposals includes a discussion of the rationale, objective, basic design, sample population, data to be gathered, procedure or instruments to be used, relationships of the research to the currentstate of knowledge in the area, and the planned analysis. The proposed studies will explore: (1) the development of bilingual and bicultural testing instruments, (2) dialect development, (3) ethnic group membership of children and their stimulus preference, (4) the relationship of social class and social mobility to differential attitudes of teachers toward school children, (5) teacher experience and its relationship to teachers' attitudes toward culturally deprived children and Project Head Start, (6) dependency, social status, and peer selection among Project Head Start children, and (7) the cooperative trusting behavior of children in relation to ethnicity and reward conditions within the context of game theory.
