Description: Fits hierarchical signal detection theory (SDT) models to
        paired direct and indirect measures, the design used to test
        for unconscious processing. Continuous indirect measures
        (typically response times) are dichotomized with the
        within-subject median split of Meyen et al. (2022)
        <doi:10.1037/xge0001065> so that both tasks are placed on a
        common sensitivity scale. The package estimates a binomial
        probit mixed model in which the two sensitivities are
        correlated random effects, and tests the three hypotheses of
        interest: the group-level difference between sensitivities,
        their latent correlation, and the latent regression of the
        indirect on the direct measure, whose intercept is the test for
        unconscious processing. Frequentist estimation uses 'lme4'.
