Working Memory | Baddeley & Hitch 1974 | Memory | Cognitive Psychology

In 1974, Baddeley & Hitch presented a new theory of primary memory, which distinguished itself from previous theories by splitting up the memory store into multiple components.

The Working Memory Model divides primary memory into the following parts:

The Central Executive
A core, supervisory module. The Central Executive controls the flow of information to and from the various slave systems and conscious thought.

The Visuo-Spatial Sketchpad
Split into two parts, the Visuo-Spatial sketchpad is responsible for visual information. For example recalling a journey, or picturing a scene. The Visual Cache interprets information about colour and form (something of an inner eye), and the Inner Scribe arranges visual information in the 'mind's eye'.

The Phonological Loop
This element of Working Memory is responsible for auditory and semantic information. The Phonological Store operates as an inner ear, whilst the Articulatory Process rehearses words to keep them in Working Memory whilst required.

The Episodic Buffer
Not much is known about the Episodic Buffer, but it is assumed that Working Memory must have an interaction with Long Term Memory, and so the Episodic Buffer has been included in the model to represent this function.

Baddeley & Hitch's model has been repeatedly tested and developed over the last few decades and remains the leading theory of primary memory. The model receives empirical support from dual-task studies as well as brain-damage case studies, such as KF.

Been reading this model over and over again for 3 hours now - saw this video and understund the whole thing in one go haha. Cheers!

[kelsie.j]

I have a very specific learning style and the way you explained the material was better than any of my lecturers

[mollyparr]

This has legit saved my degree. Thank You!

[Hiitsadam]

Explained so much better than my prof. Thanks!

[baqirqadri]

this video has helped with the struggles I had with cognitive psychology. cheers

[bhavnachopra]

Very helpful, my learners paid attention for the first time. Keep doing the good job. They proved the model wrong, they could perform dual task with the same store easily

[emmap]

Omg a lifesaver for my final thanks so much!

[RozasCooking]

Huge thanks for this great, short, informative psych-bit :) All the best!

[adriemanquero]

Thank you so much for this video! Really well explained and far easier to understand than the original paper (which I've read various times and never fully understood)

[ellissiaporter]

Thank you so much for this video it has been so helpful! Really feel like I understand this concept of working memory so much better! Loved how clear your explanations are! I was just wondering if the episodic buffer only retrieves info from long term to short term memory or does it 'translate' information in working memory to long term memory too? Thank you again x

[shrawastilavanya]

thank you for explaining in the simplest way possible, none others could help me understand this!

[wlfie_gacha]

So easy to understand a subject that I just couldn't get my head around. Very well explained thank you

The idea of visuo-spatial 'sketchpad' is inaccurate because it implies a fixed limit to what you can hold in that sketchpad. When you compare activating a LTM chunk(involving memorized and unmemorized words) and a STM chunk to comparing a STM chunk of the same length it is not the same. The LTM+STM of the same length chunk wins out. So if you can repeat back the LTM chunk and then the STM which as I said was accurately done at a longer length, you would be holding more information in your mental workspace, so this suggests working memory is less of a sketchpad and more of an activation and holding of memories in the brain which admittedly is a poor explanation but still probably closer to the truth. A model should not only work for working memory but also for long term memories and everything in-between and their interactions.

Can anyone help?? I really can’t find anywhere what the double arrows mean? As in once the central executive sorts the incoming data into the phonological loop, what does the reverse arrow mean??

[cecileabensur]

Compliments to the imaginative naming committee

[yelinlee]

Tnx! Ur clear explanation helped me understand this complicated and abstract concept.
Can I ask u a question. U said that episodic buffer connects visuospatial sketchpand and phonological loop with longterm memeory. I thought it was control excutive that interacts with longterm memory. Could u explain it in detail? thanks again!!

[ishaniiyer]

Nice work!! Great Help in UGC NET India

[CrazyFactory]

Thank you so much for creating this channel! This has been remarkably helpful.

[tafadzwazw]

well explained keep posting this is amazing your explanations are short and precise and make so much sense .

[bssawain]

I have greatly understand these terms.. you've explained it so greatly.. can you also explain the explicit and implicit memory.. ?
