Kristen recruited a group of participants and randomly divided them into two subgroups. The first group watched pictures that were likely to induce anger, whereas the second group watched pictures that were emotionally-neutral. The heart rate of the participants was measured right after. Then, the two groups were tested for memory of the pictures they just saw by a recognition test. Which of the following could be TRUE? A ) The mean heart rate was faster in the first group than in the second group, which indicates that showing anger-related pictures was effective in activating the sympathetic nervous system B ) The memory performance was better in the first group, than in the second group, which indicates that heightened sympathetic nervous system causes low memory performance. C ) The memory performance was better in the second group, than in the first group, which indicates that feeling anger caused failures in retrieving the memory of pictures. D ) The memory performance was better in the second group, than in the first group, which indicates that feeling anger caused failures in encoding of pictures into memory.
