Creating an E-Prime program

Taken from the e-studio ‘Getting Started’ guide

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)

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

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

Create a Welcome Screen1. 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

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

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

• Now create a “Good-bye” object

• Place this in the Session-Proc timeline to come after the INSTRUCTIONS object

10

1. Drag a list object from the toolbox to the SessionProc

2. Rename it as BlockList

3. Double-click the BlockList object

11

1. Create a new Procedure called BlockProc

2. Type BlockProc in the Procedure column of the list object, press <enter>

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

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

1. Click the “add attribute button”

2. Specify the name of the attribute to be PrimeGender

3. Select the default to be female

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

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

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

Defining the TrialProc1. 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

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

1. Drag a third TextDisplay object to the TrialProc timeline

2. Rename this as Target

3. Set it to display the [Target] attribute

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

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

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

Finished!1. Select the View Script option from

the View menu

2. Generate your script

3. Then run your experiment
