What is the Difference Between Working Memory Span and Short-Term Memory?
| Step | Action | Novel Insight | Risk Factors |
|---|---|---|---|
| 1 | Define short-term memory | Short-term memory is the ability to hold a small amount of information in mind for a brief period of time, typically up to 30 seconds. | Short-term memory can be easily disrupted by distractions or interference from other information. |
| 2 | Define working memory span | Working memory span is the ability to hold and manipulate information in mind for a short period of time, typically up to 20 seconds. It involves not only storage but also attentional control and maintenance rehearsal. | Working memory span is limited in capacity and can be affected by factors such as age, cognitive load, and individual differences. |
| 3 | Compare capacity | Short-term memory has a limited capacity, typically around 7 items (plus or minus 2), whereas working memory span can vary depending on the complexity of the task and the individual‘s cognitive abilities. | The capacity of both short-term memory and working memory span can be affected by chunking, which involves grouping information into meaningful units. |
| 4 | Compare duration | Short-term memory has a brief duration, typically up to 30 seconds, whereas working memory span can last up to 20 seconds with active rehearsal. | Both short-term memory and working memory span can be affected by interference, which occurs when new information interferes with the ability to remember previously learned information. |
| 5 | Compare encoding | Short-term memory relies on encoding through sensory input, whereas working memory span involves encoding through attentional control and maintenance rehearsal. | Both short-term memory and working memory span can be affected by decay, which occurs when information fades over time due to lack of use or consolidation. |
| 6 | Compare retrieval | Short-term memory involves retrieval through recognition or recall, whereas working memory span involves retrieval through manipulation or transformation of information. | Both short-term memory and working memory span can be affected by forgetting, which occurs when information cannot be retrieved due to interference, decay, or lack of consolidation. |
| 7 | Compare attentional control | Working memory span requires attentional control to maintain and manipulate information, whereas short-term memory does not necessarily require attentional control. | Both short-term memory and working memory span can be affected by individual differences in attentional control, such as ADHD or aging. |
| 8 | Compare maintenance rehearsal | Working memory span involves maintenance rehearsal, which involves actively repeating information to keep it in mind, whereas short-term memory does not necessarily involve maintenance rehearsal. | Both short-term memory and working memory span can be affected by individual differences in maintenance rehearsal ability, such as working memory capacity or cognitive load. |

Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Working memory and short-term memory are the same thing. | While both involve holding information temporarily, working memory is a more complex process that involves actively manipulating and using that information for cognitive tasks. Short-term memory is simply the ability to hold onto information briefly before it fades away. |
| Working memory has an unlimited capacity. | Working memory has a limited capacity, typically around 7 items or chunks of information at a time. This limit can be increased with practice and strategies such as chunking, but there is still a finite amount of information that can be held in working memory at once. |
| Short-term memories are stored in different parts of the brain than working memories. | Both types of memories involve similar neural processes and are thought to rely on overlapping brain regions such as the prefrontal cortex and hippocampus. The main difference between them lies in how they are used – short-term memories tend to be passive while working memories require active manipulation and use of the stored information. |
| Rehearsal is necessary for both short-term and working memory retention. | While rehearsal (repeating or reviewing) can help maintain information in both types of memory, it may not always be necessary or effective for retaining all types of information in either type of memory system. Other factors such as attention, meaning/contextual relevance, emotional salience etc., also play important roles in determining what gets retained in these systems. |
| Working Memory only lasts up to 30 seconds whereas Short-Term Memory lasts up to several minutes. | This view point confuses "working" vs "long term" storage rather than "short term" vs "working". In reality, both short term & working memories last only seconds unless rehearsed/refreshed through repetition or other means like elaboration/relevance etc., which then allows some transfer into long-term memory. |
