Mechanisms for agent-specific health decision-making in FRED. Agents can query the information layer to assess, for example, the current incidence, resulting in a perception (“how susceptible am I to the disease?”). Perceptions can be used by a behavior change model that determines whether to change the agent’s intention to perform the health-related behavior. These features permits the FRED developer to investigate a wide variety of alternative health behavior change models, including the Health Belief Model [36, 37].
