A fifth year quantitative graduate student,\u003Cstrong\u003EMatthew Barrett\u003C\/strong\u003E, recently received a seed grant from the Center of Advanced Brain Imaging (CABI) to conduct his dissertation project titled \u0026ldquo;Integrating Neuroimaging and Behavioral Data Using the Multidimensional Generalized Graded Unfolding Model for the Response Process.\u0026rdquo; The project seeks to merge neuroimaging methodologies with a quantitative item response theory (IRT) model developed in the PRD Lab. It will measure the degree to which neural signal collected from a task performed during a functional magnetic resonance imaging (fMRI) session can inform and reduce error in parameter estimation in an IRT model using self-reported preference data from the same task. Simultaneously, information about the multidimensional latent continuum established by the IRT model will be utilized to increase signal-to-noise in the fMRI data. The $8,500 grant will be used to fund data collection at CABI; it is the first research project of its kind to attempt to interface the two data modalities.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EThe Psychometric Research and Development (PRD) Lab has an exciting new project crossing disciplines within Psychology.\u003C\/p\u003E\r\n","format":"limited_html"}],"field_summary_sentence":[{"value":"The Psychometric Research and Development (PRD) Lab has an exciting new project crossing disciplines within Psychology."}],"uid":"27570","created_gmt":"2017-09-25 19:04:47","changed_gmt":"2017-09-25 19:12:57","author":"Will Rusk","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2017-09-25T00:00:00-04:00","iso_date":"2017-09-25T00:00:00-04:00","tz":"America\/New_York"},"extras":[],"hg_media":{"596453":{"id":"596453","type":"image","title":"Psychometric Research and Development Lab","body":null,"created":"1506366202","gmt_created":"2017-09-25 19:03:22","changed":"1506366202","gmt_changed":"2017-09-25 19:03:22","alt":"Psychometric Research and Development Lab Logo","file":{"fid":"227326","name":"prdlab.jpg","image_path":"\/sites\/default\/files\/images\/prdlab.jpg","image_full_path":"http:\/\/www.tlwarc.hg.gatech.edu\/\/sites\/default\/files\/images\/prdlab.jpg","mime":"image\/jpeg","size":34325,"path_740":"http:\/\/www.tlwarc.hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/prdlab.jpg?itok=T2SXBAYg"}}},"media_ids":["596453"],"groups":[{"id":"443951","name":"School of Psychology"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
