Convergence: Connecting Levels of Analysis in Psychological Science
 In the past, our field harbored distinct, and often competing, schools of thought that tackled different problems and produced findings that often appeared to diverge. Today, investigators attack shared problems at complementary levels of analysis and produce results that converge. Studies of people in a social world; mental systems of cognition and emotion; and biological mechanisms of the genome and the nervous system interconnect and yield an integrated psychological science. The APS 23rd Annual Convention displays, and celebrates, these advances in our field.

APS-SMEP Methodological Workshop Series

Randomization Tests for Single-Case Experiments Using R

Thursday, May 24, 2012, 11:30 AM - 3:20 PM

Patrick M. Onghena Chair: Patrick M. Onghena
Katholieke Universiteit Leuven, Belgium

In this workshop, participants will be introduced to the Single Case Randomization Tests, R version (SCRT-R) package. Some theoretical background regarding randomization tests will be provided, together with exercises and hands-on experience using the package. Participants will be shown how to perform a visual analysis (making a graphical representation of the single-case data, plotting a measure of central tendency, displaying information about variability in the data, and visualizing trends); how to calculate randomization test p-values; how to include effect size measures in their analyses (Standardized Mean Difference, Percentage of Nonoverlapping Data, and Percentage of Data points Exceeding the Median); and how to perform a meta-analysis of replicated single-case experiments. The focus of this workshop will be on behavioral applications and on understanding the results of statistical analyses rather than on the mathematical or algorithmic background of the techniques presented.

This workshop is cosponsored by the Association for Psychological Science (APS) and the Society of Multivariate Experimental Psychology (SMEP). Separate registration is required for workshops, which are open to Convention and/or Teaching Institute registrants only.
