An educational experiment concerning second language acquisition is described in this report. It is hypothesized that low ethnocentrism, positive attitudes toward the other group, and an integrative orientation toward language comprise high motivation, with the opposite criteria controlling low motivation. Puerto Rican children involved in the experiment completed attitudinal questionnaires concerning American culture. The questionnaire covered these areas: (1) plans for residence in the United States, (2) attitudes toward Americans, (3) expectations, (4) goals for children, (5) language, (6) social distance, and (7) political party affiliations.
