A measure of short-term memory. It is the number of digits someone can remember

digit span

A common method to assess the capacity and duration of short-term memory is the digit span test. This activity involves having a partner read a series of random numbers aloud. Immediately after the sequence is read, the listener must attempt to recall and write down the numbers in the correct order.

Comparing Immediate Memory Capacity

A researcher administers a test where participants listen to a sequence of random numbers and must immediately repeat them back in the correct order. The length of the sequence increases with each successful trial. Participant X consistently recalls sequences of 8 numbers but fails at 9. Participant Y consistently recalls sequences of 4 numbers but fails at 5. Based solely on these results, what is the most accurate conclusion?
