Eyewitness testimony
Psychologist Elizabeth Loftus conducted the famous psychology experiment known as the 'Car crash experiment' where participants watched slides of a car accident and were asked to describe the events as if they were eyewitnesses. The participants were divided into two groups and each group was asked questions worded differently like “how fast was the car driving at the time of impact?” versus “how fast was the car going when it smashed into the other car?”
It was found that the use of different verbs affected the participants' memories of the accident, showing that memories can be distorted!
