Answer:
C) about 7
Explanation:
Being precise, the average digit span that George Miller found was 9.3. Unlike the average span for letters, which rounds the 7.3 digit. In his investigation, Miller tried to find empirical data for the short term memory using letters and digits. Later investigation showed that short term memory is around 15 o 30 seconds and is based on the repetition of the data trough an acoustic process named 'rehearsal'.
Based on the description above, it is explained that all things are considered and treated equally and in addition, a person who is good listening and is someone who listens well to others are likely to be more favored than those who do not listen as people who listens are likely to follow the rules than those people who does not listen and childishly ignores them. <span />
