In a 1953 study by Edward Cherry, participants were asked to wear headphones through which a different message was delivered to
each ear. Each participant was asked to listen to one of the two messages and repeat it. Later on, participants were tested to see how much of the messages they remembered. What were the results of this study?
During the first stage of the experiment known by psychologists as the cocktail party effect, Edward Cherry he could determine:
