Results for PSYC 250: Methodology of Research in Behavioral Sciences

Statistical and methodological issues in three major psychiatric research themes: clinical psychiatric research (Aut), neuroimaging research (Win), and statistical genetics and general statistical modeling (Spr). Autumn series includes: basics of inferential statistics, group comparison, analysis of variance, regression analysis, multivariate analysis, and longitudinal analysis in the context of psychiatric and behavioral research. Also included are conceptual topics such as risk factors, mediation, moderation, and causal inference. Winter series includes: functional and structural neuroimaging research methods (e.g. functional magnetic resonance imaging (fMRI), structural MRI (sMRI), diffusion tensor imaging (DTI), transcranial magnetic stimulation (TMS), near-infrared spectroscopy (NIRS), electroencephalogram (EEG)). Basic principles, statistical analysis methods, advantages and limitations, and applications are discussed. Spring series includes: tests and effect estimation for multiple SNPs, genes or pathways in genetic association studies, gene-gene interactions, twins and heritability estimates, Hardy-Weinberg and linkage equilibrium, interpretation and presentation of results for a range of statistical models for different types of data. Practical examples from recent research within the Department of Psychiatry will be used throughout the course. Prerequisite: Some exposure to statistical methods, either from course work or from participation in research having some behavioral aspects, or consent of instructor. 1 unit for class participation only, 2 units includes weekly assignments, 3 units includes a final project.
