Final answer:
The experiment determined that the limits of focusing in short-term memory vary depending on the type of report. In full reports, people were able to recall 4-5 items, while in partial specific reports, they were able to recall 3.3 items. This suggests that the capacity of short-term memory is limited and that the ability to focus on specific items within that capacity may be reduced.
Step-by-step explanation:
The experiment determined that the limits of focusing in short-term memory vary depending on the type of report. In full reports, where people are able to recall all the items, the experiment found that people were able to report 4-5 items. However, in partial specific reports, where people were only able to recall a subset of the items, the experiment found that people were able to report 3.3 items. This suggests that the capacity of short-term memory is limited and that the ability to focus on specific items within that capacity may be reduced.
