A second group was asked: "How fast were the cars going when they bumped into each other?" A third group was asked: "How fast were the cars going when they contacted each other?" Participants in each condition estimated (in miles per hour) the speed at which the vehicle was traveling. The results are presented in the table below.

One-way ANOVA
Loftus and Palmer (1974) demonstrated how the phrasing of questions regarding a
perceived event could influence witnesses' memories of the event. In other words, memory is
malleable depending on what and how we are asked to recall or describe a past event.
In a replication of this classic study, an investigator showed a film of two cars crashing
into each other to a group of participants. Later, some participants were asked: "How fast were
the cars going when they smashed into each other?" A second group was asked: "How fast were
the cars going when they bumped into each other?" A third group was asked: "How fast were the
cars going when they contacted each other?" Participants in each condition estimated (in miles
per hour) the speed at which the vehicle was traveling. The results are presented in the table
below.

2. Did the phrasing of questions about the event affect the participants' recall? Based on these
results, what can you conclude about the effect of question phrasing on recall of emotionally
charged events?
