ABSTRACT
Our understanding of the effects of culture on temperament is in its infancy compared to the rest of the knowledge base on temperament. Of necessity, the original New York Longitudinal Study (NYLS) attempted to control for environmental factors and thus examined a relatively homogeneous cultural group in order to ferret out individual characteristics. Later, however, Chess and Thomas laid the foundation for further research on culture and temperament in the NYLS Puerto Rican study. Super and Harkness and other authors (this volume) have elaborated on this issue, making significant contributions to the field.
