Loftus & Palmer (1974) conducted a study investigating the role of language on eyewitness memory. A group of college students were shown a video clip of an automobile accident. One group was asked, "About how fast were the cars going when they smashed into each other?" The other group was asked, "About how fast were the cars going when they bumped each other?" Below are some made-up data, but they are similar to what Loftus & Palmer found. Here are the (made-up) data, measured in miles per hour: WORDING "Bumped" "Smashed" (Group 1) (Group 2) 65 81 72 89 ommu 67 75 66 65 67 72 76 82 75 81 You will set up your SPSS dataset with two variables: WORDING and SPEED. Within the WORDING variable, you will label "Bumped" as group 1 and "Smashed" as group 2. Then you will test the hypothesis that participants with the "smashed" wording made significantly different speed estimates than participants with the "bumped" wording. SPSS INSTRUCTIONS (students often mess up the parts highlighted in blue, below-be very careful about following these instructions exactly!: 1. Open IBM SPSS. 2. In the first window that pops up, choose "New Dataset," then click "OK". If the screen is cutting off and you can't see the "OK" button, you can just hit the ENTER button on your keyboard. Go to Variable View (tab on bottom left of screen). Create a variable called "WORDING" in row 1, and a variable called "SPEED" in row 2. 5. For the WORDING variable you just created, look at the column labeled "Values". Click on the first cell in that column. Either a box called "Value labels" should pop up, or you will just see a small blue box with a "..." appear in the cell that you just clicked on. If you small blue box appeared in the cell, click the small blue "..." box. NOW, no matter what, you should be looking at a pop-up box called "Value labels". 6. In the Value Labels box: a. Type in "1" for the Value, "Bumped" for the Label. Click "Add". b. Type in "2" for the Value, "Smashed for the Label. Click "Add". c. Click "OK" to close the Value Labels box. 7. Go back to Data View (tab on bottom left of screen). 8. Fill in the values for the WORDING variable in the following way
