This is was laboratory experiment , and the experimental design was independent measures.

3

Outline the participants used in experiment 1.

45 students from the University of Washington.

4

How many film clips did each participant have to watch and how long were they in experiment 1?

Participants watched 7 film clips each 5-30 seconds long.

5

What did the participants have to do after each clip in experiment 1?

After each clip participants completed a questionnaire which contained a critical question.

6

What was the critical question in experiment 1 and what were the conditions.

The critical question was: "About how fast were the cars going when they ***** each other?". There were 5 verb conditions: 'contacted' , 'hit' , 'bumped' , 'collided' and 'smashed'.

7

What was the largest and smallest estimates for the speed of cars and which verb conditions were these for?

The largest was 40.8mph with the verb 'Smashed' , and the smallest was 31.8mph with the verb 'Contacted'.

8

What do the results of experiment 1 conclude about memory?

That it can be influenced by a leading question and that the more violent the verb, the higher the estimate for speed was.

9

What was the aim of experiment 2?

To see if the 'smashed' condition is more likely than 2 other groups ('hit' and control) to say they saw broken glass when there wasn't any.

10

A multiple car crash. The clip lasted less than 1 minute (accident lasted 4 seconds).

The questions asked after an event can cause a reconstruction of ones memory.
