How many participants were in Loftus and Palmer's second experiment?

The correct answer is: 150

In Loftus and Palmer's second experiment, there were indeed 150 participants. This study aimed to investigate the effects of leading questions on memory recall, specifically focusing on how the wording of a question could influence an individual's recollection of an event. The larger number of participants allowed for more robust data and increased the reliability of the findings. Each participant was shown a film of a car accident and then asked questions about what they had seen, with variations in the wording of the questions employed to examine how these changes could alter the participants' recollection of details, such as the speed of the vehicles involved. Having 150 participants was beneficial in drawing conclusions about the broader implications of memory distortion in eyewitness testimony.
