68. In a study, participants are shown a video of a red car and a white car driving on a road and after some time had passed, they were asked to recall what happened. Which participant response indicates the influence of the misinformation effect?
Answer: C
A participant initially said they saw the red car speed up, but after reading a summary of what happened they changed their report.
This response illustrates the misinformation effect, where participants' memories are altered after being exposed to misleading information, in this case, a summary that contradicts their original recall.
A) A participant said they remember the white car speeding up because they owned a similar car and knew it was fast.
This option reflects the participant's personal experience and confidence in their recall but does not indicate the misinformation effect. Their memory is based on a pre-existing belief rather than new, misleading information.
B) A participant said they remembered seeing the red car speeding up because they had a vague memory of the red car being in front.
This response suggests a weak memory but does not demonstrate the misinformation effect. The participant's recollection is based on their own uncertainty rather than an external source of misleading information.
C) A participant initially said they saw the red car speed up, but after reading a summary of what happened they changed their report.
This response is indicative of the misinformation effect, where the participant's original memory is modified after being exposed to a summary that provides new, possibly misleading information about the event.
D) A participant initially said they saw the red car speed up but changed their mind when they saw the researcher frown.
This response does not illustrate the misinformation effect since the change in memory is influenced by the researcher’s non-verbal cue rather than any misleading information provided post-event.
Conclusion
Option C is the only response that clearly demonstrates the misinformation effect, as the participant's memory changed due to exposure to misleading information after the event. The other options either reflect personal biases, vague memories, or reactions to external cues, which do not meet the criteria of the misinformation effect. Thus, C is definitively the correct answer.
