Forming a meaningful grouping of stimuli so they can be stored as a unit in short-term memory is called

A-Processing
B-Memory
C-Rehearsal
D-Chunking

D- Chunking

D- Chunking

The correct answer is D- Chunking.

To arrive at this answer, let's break down each option and see which one fits the description given.

A- Processing: Processing refers to the mental operations involved in encoding, storing, and retrieving information. While important for memory, it does not specifically address the formation of meaningful groupings of stimuli.

B- Memory: Memory is the mental process of encoding, storing, and retrieving information. While forming meaningful groupings of stimuli is a part of memory, it does not specifically refer to the process described in the question.

C- Rehearsal: Rehearsal refers to the act of consciously repeating information to maintain it in short-term memory or to transfer it to long-term memory. While rehearsal can be used to aid memory, it is not specifically about forming meaningful groupings of stimuli.

D- Chunking: Chunking is the process of organizing or grouping individual bits of information into larger, more meaningful units. This strategy allows for more efficient storage and retrieval of information in short-term memory. It helps overcome the limited capacity of short-term memory by grouping stimuli into a smaller number of meaningful chunks. For example, remembering a phone number as three chunks, such as "555-123-4567," is easier than remembering it as a string of ten individual digits. Therefore, the process described in the question is called chunking.
