Description: DMC model simulation detailed in Ulrich, R., Schroeter,
        H., Leuthold, H., & Birngruber, T. (2015). Automatic and
        controlled stimulus processing in conflict tasks: Superimposed
        diffusion processes and delta functions. Cognitive Psychology,
        78, 148-174. Ulrich et al. (2015)
        <doi:10.1016/j.cogpsych.2015.02.005>. Decision processes within
        choice reaction-time (CRT) tasks are often modelled using
        evidence accumulation models (EAMs), a variation of which is
        the Diffusion Decision Model (DDM, for a review, see Ratcliff &
        McKoon, 2008). Ulrich et al. (2015) introduced a Diffusion
        Model for Conflict tasks (DMC). The DMC model combines common
        features from within standard diffusion models with the
        addition of superimposed controlled and automatic activation.
        The DMC model is used to explain distributional reaction time
        (and error rate) patterns in common behavioural conflict-like
        tasks (e.g., Flanker task, Simon task). This R-package
        implements the DMC model and provides functionality to fit the
        model to observed data. Further details are provided in the
        following paper: Mackenzie, I.G., & Dudschig, C. (2021).
