Working Memory - Baddeley and Hitch (1974)

The video explores Baddeley and Hitch's Working Memory Model, which redefines short-term memory as a complex system with multiple components: the central executive, phonological loop, visuo-spatial sketchpad, and episodic buffer. The central executive organizes information, while the phonological loop and visuo-spatial sketchpad handle auditory and visual data, respectively. The episodic buffer connects working memory with long-term memory. The dual-task paradigm demonstrates the model's validity, showing that tasks using different systems can be performed simultaneously. The KF case study supports the model's claim of distinct memory systems. Despite its insights, the model is not exhaustive.

What is the primary role of the central executive in the Working Memory Model?

• To manage and organize information attended by the slave systems

• To store auditory information

• To store visual and spatial data

• To rehearse words to keep them in working memory

Which component of the Working Memory Model is responsible for handling auditory information?

• Central executive

• Visuo-spatial sketchpad

• Phonological loop

• Episodic buffer

What are the two parts of the visuo-spatial sketchpad?

• Phonological store and articulatory process

• Visual cache and inner scribe

• Inner ear and inner voice

• Central executive and episodic buffer

What does the episodic buffer in the Working Memory Model aim to explain?

• The organization of information by the central executive

• The rehearsal of words in working memory

• The storage of auditory information

• The interaction between working memory and long-term memory

What does the KF case study suggest about the slave systems in the Working Memory Model?

• They only handle verbal information

• They are both operationally distinct and anatomically separate

• They are operationally distinct but not anatomically separate

• They are not distinct and operate as a single system
