Continuous indirect measures\n(typically response times) are dichotomized with the\nwithin-subject median split of Meyen et al. (2022)\n so that both tasks are placed on a\ncommon sensitivity scale. The package estimates a binomial\nprobit mixed model in which the two sensitivities are\ncorrelated random effects, and tests the three hypotheses of\ninterest: the group-level difference between sensitivities,\ntheir latent correlation, and the latent regression of the\nindirect on the direct measure, whose intercept is the test for\nunconscious processing. Frequentist estimation uses 'lme4'.", "License": "GPL-3", "Encoding": "UTF-8", "LazyData": "true", "LazyDataCompression": "xz", "VignetteBuilder": "knitr", "Roxygen": "list(markdown = TRUE)",
