During your finger's trip from phone book to phone, your memory of a telephone number may evaporate.

After 3 seconds people recalled the letters only about half the time; after 12 seconds, they seldom recalled them at all (FIGURE 8.9). Without active processing, short-term memories have a limited life. I Short-term memory is limited not only in duration but also in capacity. As noted earlier, our short-Short-term memory is limited not only in duration but also in capacity....
