A group of students is investigating memory. The students performed an experiment in which they showed letters on a screen to participants, and afterward asked participants to recall which letters they saw. Next, they showed the participants the letters and, at the same time, pronounced the sound that the letter represents. Which prediction and explanation are most likely to be correct?
The participants would remember the most letters during the first trial since their memory was fresh.
The participants would remember more letters during the first trial because the sound interferes with the ability to form memory.
The participants would remember more letters while hearing the letter pronounced because information was received in more than one way.
The participants would remember more letters while hearing the letter pronounced because sound input becomes memory faster than visual input does.
