A presentation is made of the cultural assumptions which it is believed underlie a great deal of the role playing in the Mexican family. Examples are given to demonstrate the effect of the assumptions in actual role playing. Remarks are made regarding (1) the areas where neurotic difficulty would be expected from the assumptions and the role playing, and ( 2) some evidence which seems to verify such expectations. It is proposed that opinion polls may serve the purpose of identifying the degree of variation of a given group from the dominant pattern.Abstract Teaser
