The fоllоwing scenаriо will be importаnt for аnswering the next two questions. Dr. Valverde, a social psychologist, conducts an experiment examining the effect of sociality on memory. He provides lists of 15 words to two groups of participants at his university. He puts the names of all the participants in a hat. The first 20 names he assigns to Group A and the last 20 he assigns to Group B. Participants in Group A are given their list while all together in the same room. Participants in Group B see the list of words while they are alone. Dr. Valverde then measures how many words each group is able to remember after being distracted for 5 minutes by watching a video about the history of the university. He finds that Group B remembers 15% more words than Group A.
