Quizplus · Accepted Answer

The rearrangement of the letters into groups of meaningful chunks (HBO, JFK, CIA, ABC) is an example of chunking, which is a useful strategy for enhancing the capacity of short-term memory. Chunking involves grouping individual pieces of information into larger, meaningful units, which helps to reduce the number of items that need to be remembered and improves retention. Rehearsal involves repeating information to keep it in short-term memory, peg-word systems involve associating new information with already known information, and the method of loci involves visualizing information in a spatial context. While these strategies can also be helpful for memory, the given scenario specifically illustrates the usefulness of chunking.
