# Chunking: Increasing the Capacity of STM

The digit span experiment you just tried suggests that people can store, on average, seven bits of information in their STM at one time. Is it possible to increase this capacity?

Try the demonstration on the right. It is based on the digit span experiment you just tried, with a couple of differences. First, there are only two digit lists to try to recall. Second, each digit list is substantially longer than the ones in the last experiment.
