Demonstrating Short-term Memory

We did an activity in class which demonstrates each of our abilities to remember numbers. The numbers were recited starting from three digits and increases with different arrangements each time. According the psychologists, normal people can remember about seven (plus or minus two) pieces of information for each short-term memory. The result of the class clearly proves the point. The most information that the students were able to obtain were nine digits whereas the least was five.

There are several ways to improve one’s short-term memory in terms of capacity. One way is to relate the numbers into a story or something which reminds you of the numbers (i.e. birth year or telephone numbers). Or, you can try to separate the numbers into chunks, or in other words, group it. This experiment does prove that people’s capacity to remember numbers are somewhat similar depending on each people’s strategies.
