Question: 244

1. What conclusions can be drawn from the data presented in Table 1?

  • A. The misinformation effect is present in the decoy group.
  • B. The control group had a better memory than the decoy group.
  • C. There are no significant differences between the decoy and the control group.
  • D. No conclusions can be drawn from these data.

Correct Answer: A

Explanation:

Based on the data presented in Table 1, one can reasonably conclude that the misinformation effect is present in the decoy group. As noted in the table, the overwhelming majority of participants positively identified the custodial worker as the mugger, most likely because his face was presented to the participants before the memory of the mugging could be fully encoded (choice A is correct). Although the control group chose the mugger at a higher rate than did the decoy group, this is not enough information to reasonably conclude that the control group has a better memory (choice B is wrong). Based on the data in Table 1, there are significant differences between the decoy group and the control group. The decoy group overwhelmingly chose the custodial worker as the suspect over the other photo choices, whereas the control group chose the actual mugger at a slightly higher rate (choice C is wrong). Based on these findings, some conclusions can indeed be drawn from these data (choice D is wrong).
