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'.
