Digital platforms such as LinkedIn have transformed how organizational leaders present themselves and engage with professional networks. Despite the increasing frequency of emotionally charged content in these environments, the cognitive and emotional processes that affect leaders' responses remain poorly understood. This research proposal aims to investigate how mentalization, the capacity to understand one's own and others' mental states, and emotion regulation interact with cognitive load and digital engagement when leaders face compassionate empathy versus personal distress content online. Leadership tenure and seniority will be examined as key moderating variables. A mixed-methods, within-subjects experimental design will be implemented with a sample of 60 to 100 leaders and managers active on LinkedIn. Participants will view validated LinkedIn-style posts differing in affective tone, with responses measured through established psychometric instruments (MentS, DERS/ERQ, NASA-TLX, PANAS, IRI) and open-ended qualitative questions. Quantitative analysis will test mediation and moderation effects, while thematic analysis will explore leaders' subjective experiences. It is hypothesized that compassionate empathy content will promote higher engagement and lower cognitive load, especially among leaders with greater experience. Findings are expected to advance the theoretical understanding of digital leadership, inform the design of psychologically safer digital environments, and support interventions to enhance executive well-being in the digital age.
