The Complete Companions: Models of Memory

TL;DR

This content explains the new specifications for memory models, including coding, capacity, and duration for the multi-store model, and coding and capacity for the working memory model.

Transcript

So, you're all faced with a new specification  and one of the dangers of a new specification is   missing those little bitty things that are new  to the specification. That's one of the things   Mike and I are good at; we're very experienced at  decoding a specification. So I'm going to talk to   you a little bit about their models of memory:  the ... Read More

Key Insights

• 👶 Familiarizing oneself with the new specifications for memory models is crucial to accurately understanding and applying them in psychology.
• 🏪 The multi-store model now requires knowledge of coding, capacity, and duration for each store, such as the sensory register.
• 💦 The working memory model focuses on the coding and capacity of the Central Executive, Phonological Loop, Visuo-spatial Sketchpad, and Episodic buffer.
• ®️ The capacity of the sensory register is estimated to be around 125 million cells, emphasizing its vast storage potential.
• 📪 Research suggests that the capacity of short-term memory may be closer to the lower end of the commonly cited range.
• 🥹 The Visuo-spatial Sketchpad in the working memory model has a limited capacity for holding visual and spatial information.
• 👨‍💻 Familiarity with the coding mechanisms and capacities of the memory model components is essential for comprehensive understanding and application.

Questions & Answers

Q: Why is it important to familiarize ourselves with the new specifications for memory models?

Familiarizing ourselves with the new specifications is crucial to avoid missing any important elements and to ensure accurate understanding and application of the models in psychology research and studies.

Q: What is the capacity of the sensory register and how is its information coded?

The sensory register has a large capacity, with estimates of around 125 million cells in the human retina alone. The information in the sensory register is coded based on the sensor being used to perceive it.

Q: Is the capacity of short-term memory really limited to only seven plus or minus two items?

Recent research suggests that the capacity of short-term memory is likely closer to the lower end of that range, and students should refer to supporting research when discussing its capacity.

Q: What is the estimated capacity of the Visuo-spatial Sketchpad in the working memory model?

According to Alan Baddeley, the Visuo-spatial Sketchpad can hold around three or four objects, providing a limited capacity for visual and spatial information.
