1 Creating an E-Prime program Taken from the e-studio Getting Started guide

2 2 What do we want the program to do? Blair & Banaji (1996) – stereotype priming Participants presented with a word (PRIME) Prime is stereotypically masculine/feminine Also Positive or negative Prime replaced by fixation and then followed by TARGET word (M/F name) Task to respond to name (1 if male, 9 if female)

3 3 Structure of expt Welcome to the experiment! Thanks & Goodbye! PRIMETARGET + Set up & run trials

4 4 Procedure Acts as a timeline for events within the experiment E-Studio Elements Text Display Allows presentation of a full screen of text Image Display Allows presentation of images in bitmap (.bmp) format Slide Allows presentation of a combination of text, images and/ or sound Feedback Display Allows presentation of a combination of text, images and/ or sound List Contains all independent variables, attributes, and stimuli as well as controls sampling

5 5 Toolbox Structure - An outline (hierarchical) of your experiment Properties – Of object selected in Structure Workspace – windows of the objects you are working with will be opened here

6 6 Create a Welcome Screen 1. double-click SessionProc 2. Drag a TextDisplay from ToolBox to the SessionProc Timeline 3. Rename the object as INSTRUCTIONS in the Properties line 4. Double- click on the object to open it

7 7 Welcome to the Experiment. You will see a word followed by a fixation cross. You will then be shown another (target) word Your task is to determine if the target word was a male or female name. Press the 1 key for a male name and 9 for a female name. PRESS THE SPACEBAR TO BEGIN!

8 8 1. Change the length of display for the instructions to infinite 2. Add an Input device, so that participants can press the spacebar to move on

9 9 Now create a Good-bye object Place this in the Session-Proc timeline to come after the INSTRUCTIONS object

10 10 1.Drag a list object from the toolbox to the SessionProc 2.Rename it as BlockList 3.Double-click the BlockList object

11 11 1.Create a new Procedure called BlockProc 2.Type BlockProc in the Procedure column of the list object, press 3.Say yes to creating the new Procedure 4.Say yes to making it the default for new objects 5.Close all the windows in the workspace (not the e-studio application

12 12 1.Double-click on the BlockProc object in the structure 2.Drag a new list object to the timeline and rename it TrialList 3.Double-click on the TrialList object to open it

13 13 1.Click the add attribute button 2. Specify the name of the attribute to be PrimeGender 3. Select the default to be female

14 14 Now add all these attributes PrimeType (positive) NameGender (female) CorrectAnswer (9) Prime (?) Target (Linda) Double-Click the PROCEDURE column and specify the default value to be TrialProc

15 15 1.Create the TrialProc Procedure 2. Click the Add multiple levels tool button and specify that you want to add seven levels This gives you new levels wit the earlier specified defaults filled in 3. Complete all the lines as shown on the next screen

16 16

17 17 TrialList properties and Procedure 1. Select the properties of the TrialList object 2. Select the SELECTION tab and change the selection from Sequential to Random 3. Check that the Reset/Exit options are set to display all samples

18 18 Defining the TrialProc 1.Double-click the TrialProc in the Structure window 2.Drag a Text Display object from the toolbox to the TrialProc timeline and rename it Prime 3.Select the Properties and specify the duration to be 1000 milliseconds 4.Set the display to show the attribute you named Prime in the Trial List. To do that type [Prime] (exactly as shown)

19 19 1.Drag another TextDisplay object onto the TrialProc timeline 2.Place it after the Prime 3.Rename it as Fixation 4.Type + as the text to be displayed 5.It should be displayed for a 1000 milliseconds (default)

20 20 1. Drag a third TextDisplay object to the TrialProc timeline 2. Rename this as Target 3. Set it to display the [Target] attribute

21 21 1.Change the duration to infinite 2.Add an Input device (keyboard) 3.Add the allowable Reponses (19) 4.Specify that the Correct response is defined by the attribute [CorrectAnswer] 5.You will then get prompted to set Datalogging to Standard – confirm this

22 22 Giving Feedback 1.Drag the FeedbackDisplay object from the toolbox to the TrialProc timeline 2.In the properties find the InputObject name row and specify this as Target

23 23 Defining the Feedback To change any of the lines of the feedback, single-click them. This selects them, and you can then change them by selecting properties

24 24 Finished! 1.Select the View Script option from the View menu 2.Generate your script 3.Then run your experiment
