Which factor can have a positive impact on working memory capacity?

1. High levels of anxiety

2. Mindfulness meditation practices

3. Distractions from the environment

4. Multitasking

The correct answer is: Mindfulness meditation practices

Mindfulness meditation practices can positively impact working memory capacity by enhancing cognitive functions through focused attention and awareness. Regular engagement in mindfulness training has been shown to improve attention regulation, reduce stress levels, and increase cognitive flexibility. By practicing mindfulness, individuals learn to concentrate on the present moment, which can lead to a more effective allocation of cognitive resources. This improved focus allows for better encoding and retrieval of information, thereby enhancing working memory performance. High levels of anxiety tend to impede cognitive processes, often leading to decreased concentration and impaired memory function. Distractions from the environment can similarly disrupt cognitive activities, making it more challenging to hold and manipulate information in working memory. Multitasking is often detrimental to working memory because it requires switching attention between different tasks, which can overload cognitive resources and reduce overall effectiveness in retaining information.
