Did I text you? The influence of the mode of transmission on destination memory

In a society where people often communicate through digital technology, it is crucial to investigate whether the transmission mode influences destination memory performance (our capacity to remember to whom we transmitted certain information). In Experiment 1, we asked young adults (N = 31) to share of a set of familiar proverbs only by typing and the rest by both typing and saying them aloud. Better destination memory was observed when the information was transmitted by the two means (aloud and typing). Did this better performance occur because participants shared the information aloud or because the information was transmitted by two means? In Experiment 2, young adults (N = 34) shared familiar proverbs aloud, by typing, or simultaneously aloud and by typing. Results showed that transmission aloud led to a better destination memory than typing, and no further improvement occurred when the transmission was both aloud and by typing. Additionally, no differences were observed regarding item memory, supporting the idea that item and destination memories are two different types of memory.
