Question

Quizplus · Accepted Answer

Miller's magical number 7, plus or minus 2, refers to the limited capacity of short-term memory (STM), which can hold approximately 7 pieces of information, such as digits in a phone number. Jamal's inability to remember all of the numbers suggests that he has reached the limit of his STM capacity, rather than experiencing anterograde amnesia or retroactive interference. The curve of forgetting theory relates to the decay of information in long-term memory over time, and is not applicable in this situation.
