How many experiments did Loftus and Palmer conduct?

• 1

• 2

• 3

• 4

How many participants took part in Experiment 1 of Loftus and Palmer's study?

• 55

• 50

• 45

• 40

How many conditions (IVs) were in Experiment 1 of Loftus and Palmer's study?

• 2

• 3

• 4

• 5

Which of the following was NOT a critical question in Experiment 1 of Loftus and Palmer's study?

• About how fast were the cars travelling when they smashed into eachother?

• About how fast were the cars travelling when they contacted eachother?

• Did you see broken glass?

• About how fast were the cars travelling when they hit eachother?

Loftus and Palmer asked participants to describe the car crash. Why?

• Control against researcher bias

• Reduce the possibility of demand characteristics

• Eliminate the possibility of order effects

• Control against researcher effect

What was the dependent variable in Expetiment 1 of Loftus and Palmer's study?

• Verb used in the questions

• Yes / No to seeing broken glass

• Estimated speed of the cars (mph)

What was the independent variable in Experiment 1 of Loftus and Palmer's study?

• Verb used in the questions

• Yes / No to seeing broken glass

• Estimated speed of the cars (mph)

Which verb resulted in the largest speed estimate (40.5 mph) in Exp 1 of Loftus and Palmer's study?

• Contacted

• Bumped

• Hit

• Smashed

Which verb resulted in the smallest speed estimate (31.8 mph) in Exp 1 of Loftus and Palmer's study?

• Contacted

• Bumped

• Hit

• Smashed

At the end of Exp 1, Loftus and Palmer gave 2 possible for reasons for the differences in estimated speeds. Which of these is NOT a reason given.

• Social desirability bias (a demand characteristic)

• Response-bias (a demand characteristic)

• Memory distortion
