Mark’s work across contexts demonstrates how motivational language impacts key outcomes for organizations and individuals. Goal orientations (promotion and prevention) and states of goal pursuit (locomotion and assessment) explain some outcomes in entrepreneurship and innovation. To measure these motivations, he build linguistic measurement tools that measure motivations in conversations, correspondence, webpages, static documents, and other archives. Typically, Mark first measure psychological and motivational variables via a field observational study or archival reference. Then he proceed onto preregistered experiments and replications to pin down causality and identify potential mediators. His work has been published in Organizational Behavior and Human Decision Processes, Basic and Applied Social Psychology, Social Science Research, Academy of Management Journal, and Harvard Business Review.
