How Can We Measure and Improve Working Memory Capacity?
| Step | Action | Novel Insight | Risk Factors |
|---|---|---|---|
| 1 | Use memory span tasks to measure working memory capacity. | Memory span tasks involve presenting a series of items and asking the participant to recall them in order. This can be done with both verbal and visual-spatial information. | Memory span tasks may not fully capture the complexity of working memory and may not be sensitive enough to detect subtle changes in working memory capacity. |
| 2 | Use the dual n-back task to measure working memory capacity. | The dual n-back task involves presenting a series of stimuli (e.g. letters, sounds) and asking the participant to indicate when the current stimulus matches the one presented n trials ago in both the auditory and visual modalities. | The dual n-back task may be more sensitive to changes in working memory capacity than memory span tasks, but it may also be more difficult and time-consuming to administer. |
| 3 | Use neurofeedback training to improve working memory capacity. | Neurofeedback training involves using real-time feedback of brain activity to train individuals to regulate their brain function. This can be done using EEG or fMRI. | Neurofeedback training may be expensive and time-consuming, and the transfer effects to other cognitive domains may be limited. |
| 4 | Use mindfulness meditation to improve working memory capacity. | Mindfulness meditation involves training individuals to focus their attention on the present moment and to let go of distracting thoughts. This has been shown to improve attentional control and working memory capacity. | Mindfulness meditation may not be effective for everyone and may require a significant time commitment to see results. |
| 5 | Use mnemonic strategies and chunking techniques to improve working memory capacity. | Mnemonic strategies involve using mental associations or imagery to aid in memory recall, while chunking techniques involve grouping information into meaningful units. | Mnemonic strategies and chunking techniques may be effective for improving working memory capacity, but they require practice and may not be suitable for all types of information. |
| 6 | Use brain plasticity and memory consolidation processes to improve working memory capacity. | Brain plasticity refers to the brain’s ability to change and adapt in response to experience, while memory consolidation processes involve the transfer of information from short-term to long-term memory. | These processes may be enhanced through activities such as physical exercise, sleep, and learning new skills. However, the effects on working memory capacity may be indirect and difficult to measure. |

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 manipulating and using that information for cognitive tasks. Short-term memory is simply the ability to hold onto information briefly before it is forgotten or transferred to long-term memory. |
| Working memory capacity cannot be improved through training or practice. | Research has shown that working memory can be improved through targeted training exercises, such as dual n-back tasks or spatial span tests. However, these improvements may not transfer to other cognitive domains outside of working memory. |
| Short-term memory only lasts a few seconds at most. | The duration of short-term memory can vary depending on factors such as the type of information being held and how much attention is paid to it. Some estimates suggest that short-term memories can last up to 30 seconds without rehearsal or interference from other stimuli. |
| Working Memory Capacity (WMC) is fixed throughout life and cannot be changed by external factors like education or environment. | WMC can change over time due to various environmental factors including education, lifestyle changes, physical exercise etc., but there may also be genetic influences on individual differences in WMC which limit its potential for improvement beyond certain levels. |
| Poor performance on working/short term-memory assessments indicates low intelligence. | While poor performance on these assessments may indicate difficulties with attentional control and/or processing speed, they do not necessarily reflect overall intelligence levels since many different cognitive abilities contribute towards general intelligence scores. |
