chunking

 

Chunking refers to an approach for making more efficient use of short-term memory (STM) by grouping information.

Chunking breaks up long strings of information into units or chunks.  The resulting chunks are easier to commit to memory than a longer uninterrupted string of information.

Chunking Theory

The term “chunking” was first introduced in 1956 by George A. Miller in his paper “The Magical Number Seven, Plus or Minus Two: Some Limits on our Capacity for Processing Information.” Through his research, Miller found that short-term memory has a limited capacity.

Miller’s research into short term memory concluded that people can retain seven plus or minus two items of information in the short-term storage process of working memory at any given time. In contrast, long-term memory indefinitely stores a seemingly unlimited amount of information.

Because of its limited capacity, STM is the bottleneck in the memory system. If we can only retain about 7 items at one time in STM, then there are significant restrictions on how much information can be transferred to long-term memory (LTM). These restrictions can be overcome by chunking information into groups or units, making the seven items larger.

 

Chunking Increases Memory

Miller’s research showed that by organizing items into chunks short memory capacity can be substantially increased.

Miller discovered that an organized chunk of information functions as one item, and that a person could hold around seven chunks of information in short term working memory at the same time. These units or chunks can be thought of as seven containers each capable of holding one chunk of information in memory.

Individual letters can form into words; words can be formed into sentences, and then even into stories. Thus, more than seven letters or words can be held in short-term or working memory.

Examples of Chunking

The classic example of chunking is numbers. It is much easier to remember three sets of numbers, instead of 8 or 10 seemingly random numbers strung together.

 

Phone numbers:

8605554589 is chunked as 860-555-4589

 

Birthdates:

11261995 is chunked as 11/26/1995

Chunking Information

 

Chunking refers to an approach for making more efficient use of short-term memory by grouping information. Chunking breaks up long strings of information into units or chunks.  The resulting chunks are easier to commit to memory than a longer uninterrupted string of information.

Good chunking facilitates comprehension and retrieval of information.

 

 

Chunking Strategy

Chunking is a strategy used to reduce the cognitive load as the learner processes information. The learner groups content into small manageable units making the information easier to process. Essentially, chunking helps in the learning process by breaking long strings of information into bit size chunks that are easier to remember.

Chunking Process

There are several steps to the chunking process. The number of steps you use will depend on the type information you are chunking.

  1. Break larger amounts of information into smaller units
  2. Identify similarities or patterns
  3. Organize the information
  4. Group information into manageable units

 

 

Chunking Information

Chunking is used most commonly to organize or classify large amounts of information, even when there are no obvious patterns. Occurrences of chunking as a memory device can be seen in the way information is grouped in our daily life.

 

 

Simple Chunking

The breaking down of seemingly random numbers into chunks makes the number easier to remember.

Examples:

  1. Phone numbers are not typically seen or remembered as a long string of numbers like 8605554589, but rather 860-555-4589.
  2. Birthdates are typically not recalled by 11261995, but rather 11/26/1995.

 

Letters can also be broken down into chunks helping to remember easier.

Example:

“XLETHIPSOXWHYMIX” is difficult to remember as a long string of letters, however if the letters are grouped or chunked, remembering them is easier. The breaking down of the letters into more “logical” chunks also makes it easier to remember.

 

X LET HIP SOX WHY MIX

 

 

Chunking Lists

Chunking can also work for lists. For example, a shopping list can be segmented into categories.

Chunking Processes

Chunking can also work for processes. For example, painting a room may be divided into three groups;

  1. Preparation
  2. Painting
  3. Clean-up
