The current research examined whether life sciences vs. engineering/physical sciences vary in the visibility and value of communality and agency. Overall, we find an emphasis on agency in engineering/physical sciences and a greater balance between communality and agency in the life sciences. We examine motivational culture as represented in environmental structures (Study 1), in signals sent and received in academic displays (Studies 2A-B), and in individual-level motives and cognitions (Studies 3-4). Study 1 analyzed archival course data to find that courses (N=11,222) in engineering/physical sciences included fewer collaborative assignments than courses in life sciences. Study 2A's content analysis documented that bulletin boards (N=68) in engineering/physical sciences academic buildings conveyed less communal purpose, and Study 2B found that participants (N=44) perceived greater communal purpose when viewing novel bulletin boards experimentally manipulated to include the cues identified in Study 2A. In Studies 3 (N=326) and 4 (N=110), engineering/physical science majors reported a strong agentic focus, compared to life science majors' more balanced focus. Further, the strong agentic focus of engineering/physical science students waned over time. This investigation of motivational cultures highlights the daily practices and institutional contexts that can shape individual-level motives and cognition related to engagement in STEM, both within and across different STEM pathways.
