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

Estimation for Better Research: Effect Sizes, Confidence Intervals, and Meta-Analysis

Thursday, May 24, 2012, 9:00 AM - 12:50 PM
Chicago Ballroom X

Geoff Cumming Chair: Geoff Cumming
La Trobe University, Australia

The Publication Manual of the American Psychological Association states, “wherever possible, base discussion and interpretation of results on point and interval estimates.” This workshop will explain why an estimation approach is better than null-hypothesis significance testing and will describe how to calculate and interpret effect sizes and confidence intervals for a range of measures and designs. It will also introduce meta-analysis and the use of precision for research planning. The emphasis will be on understanding and on practical strategies. Much use will be made of the interactive simulations of Exploratory Software for Confidence Intervals (ESCI). There is more information about ESCI and the book that includes the material in the workshop at

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.
