Quiz: Working memory

What is working memory?

A cognitive system responsible for temporarily holding information for processing and manipulation.

Key components of working memory?

Central Executive, Phonological Loop, Visuospatial Sketchpad, and Episodic Buffer.

True or false: Working memory is the same as short-term memory.

False, because working memory involves manipulation of information, while short-term memory is passive.

Difference between phonological loop and visuospatial sketchpad?

Phonological loop processes verbal and auditory information; visuospatial sketchpad handles visual and spatial data.

Fill the blank: The __________ is responsible for directing attention in working memory.

Central Executive.

What does the episodic buffer do?

Integrates information from different sources and links to long-term memory.

How is working memory measured?

Using tasks like digit span, n-back tests, and word recall.

True or false: Working memory capacity is unlimited.

False, because it typically holds 7±2 items.

What impacts working memory capacity?

Factors include age, cognitive load, and attentional focus.

Example of a working memory task?

Remembering a phone number while dialing it.

Difference between working memory and long-term memory?

Working memory is short-term and active; long-term memory is for storing information over time.

Fill the blank: The __________ is often considered the 'control center' of working memory.

Central Executive.

What is the capacity of working memory in digits?

Typically, around 7 digits, plus or minus 2.

True or false: Age does not affect working memory.

False, because working memory capacity can decline with age.

Which component deals with visual information?

Visuospatial Sketchpad.

How can working memory be improved?

Techniques include chunking information, practicing memory tasks, and minimizing distractions.

Example of a dual-task interference?

Trying to remember a list of words while solving a math problem.

What role does attention play in working memory?

Attention determines what information is processed and maintained.

True or false: Working memory is not essential for learning.

False, because it is crucial for understanding and applying new information.

Fill the blank: The __________ is responsible for language processing in working memory.

Phonological Loop.
