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

The correct answer is: 45

Loftus and Palmer's first experiment involved 45 participants, which is significant as it provided a robust sample size for their investigation into the effects of leading questions on memory recall. This experiment aimed to explore how different wording of questions could influence the participants' recollections of a car accident they had witnessed through a video clip. By utilizing 45 individuals, the study was able to gather diverse reactions and outcomes, lending credibility and strength to their findings regarding the malleability of memory. The design and execution of the experiment were foundational in establishing concepts related to eyewitness testimony and the reliability of memory in legal settings.
