Reflections on the meaning and structure of the horizontal/vertical distinction

The commentaries by Aaker (2006), Meyers-Levy (2006), and Oyserman (2006) extend the implications of the horizontal/vertical distinction described in our article (Shavitt, Lalwani, Zhang, & Torelli, 2006) in a number of interesting directions. We join these authors in calling for further research on horizontal and vertical individualism and collectivism constructs. We also highlight conceptual and structural issues that remain to be resolved and evaluate priming and other operational approaches to the study of horizontal and vertical individualism and collectivism.
