Definition

1. Noun:
   • A cognitive system responsible for temporarily holding and manipulating information: "Working memory" refers to the brain's capacity to maintain a limited amount of information in an active, readily available state for a short period while it is being used in cognitive tasks like reasoning, comprehension, and learning.

Usage

• "Working memory" is a specific term used primarily in psychology, neuroscience, and education. It describes a core executive function. It is often contrasted with short-term memory (more passive storage) and long-term memory (permanent storage).

Examples

• Noun:
  • Solving this complex math problem requires good working memory to hold the intermediate steps.
  • The researcher studied how aging affects the capacity of the working memory.
