In a classic research study, two groups of participants watched the same video of a car accident where two cars collided. One group was asked to describe the scene of the accident after the two cars bumped into each other, while the other group was asked to describe the scene of the accident after the two cars smashed into each other. Researchers found that compared to the other group, the group asked about the cars smashing into each other tended to recall seeing broken glass, when in fact there was no broken glass. These results are BEST explained by:

the hindsight bias.
source amnesia.
the misinformation effect.
anterograde amnesia.
