The best analytical tools to test\nfor perceptual independence are provided by General Recognition Theory (GRT), a\nmultidimensional extension of signal detection theory. Unfortunately, there is\ncurrently a lack of software implementing GRT analyses that is ready-to-use by\nexperimental psychologists and neuroscientists with little training in\ncomputational modeling. This paper presents grtools, an R package developed\nwith the explicit aim of providing experimentalists with the ability to perform\nfull GRT analyses using only a couple of command lines. We describe the\nsoftware and provide a practical tutorial on how to perform each of the\nanalyses available in grtools. We also provide advice to researchers on best\npractices for experimental design and interpretation of results.","url_abs":"http://arxiv.org/abs/1610.03207v1","url_pdf":"http://arxiv.org/pdf/1610.03207v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"testing-separability-and-independence-of","repo_url":"https://github.com/fsotoc/grtools","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[{"task_slug":"experimental-design","task_name":"Experimental Design"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
