Tutorial: Standard Picture IAT

Download script for this tutorial.

This tutorial builds an Implicit Attitude Task (IAT) modeled after the version that runs on the Project Implicit web site (www.projectimplicit.org). This version of the task measures implicit attitudes towards flowers and insects as represented by pictures.

This tutorial walks through the process of building an IAT from scratch. If your goal is simply to adapt the IAT to your own attribute and target categories, you need only make a few simple modifications to the sample script as indicated at the end of the section on creating text stimuli; you can skip the rest. This tutorial will be of interest to anyone interested in the details of the IAT procedure, or who wishes to modify the procedure. The tutorial also illustrates a number of intermediate and advanced concepts that are relevant to other procedures besides the IAT.
