Memory Duration and Capacity Study: Exploring Long-Term and Short-Term Memory

The memory system's coding, capacity, and duration characteristics are fundamental to understanding how information is processed and stored in different memory stores, with distinct features for short-term memory (STM) and long-term memory (LTM). Research has revealed crucial differences in how these memory systems encode, store, and retain information over time.

Long-term memory duration extends significantly longer than STM, potentially lasting a lifetime
• Research demonstrates that working memory psychology operates primarily through acoustic coding
Types of long-term memory coding primarily utilize semantic processing
• Studies show short-term memory capacity typically ranges from 7±2 chunks of information
Memory coding and capacity analysis reveals distinct characteristics between STM and LTM stores

Research on Memory Systems: Coding, Capacity, and Duration

This comprehensive page explores fundamental research on memory systems, focusing on three key aspects: coding, capacity, and duration of both short-term and long-term memory.

Definition: Coding refers to the process of converting information between different forms in memory systems.

Coding Research

Baddeley's 19661966 research investigated coding differences between memory stores using word lists varying in acoustic and semantic similarity.

Example: In short-term memory experiments psychology, participants performed worse with acoustically similar words in immediate recall, while semantic similarity affected long-term recall more significantly.

Capacity Research

Multiple studies have examined memory capacity:

Highlight: Jacobs 18871887 found mean memory spans of 9.3 for digits and 7.3 for letters, while Miller 19561956 established the famous "7±2" rule for short-term memory capacity.

Duration Research

Peterson and Peterson 19591959 and Bahrick et al. 19751975 conducted significant studies on memory duration:

Example: The Short term memory duration research showed decay to 3% recall after 18 seconds without rehearsal.

Highlight: Long term memory capacity study demonstrated 70% photo recognition accuracy after 48 years.

Evaluation Points

The research presents both strengths and limitations:

Vocabulary: External validity refers to how well research findings can be applied to real-world situations.

  • Artificial stimuli usage limits generalizability
  • Replication of findings strengthens validity
  • Recent research suggests STM capacity might be closer to 4±1 chunks
  • Bahrick's study demonstrates high external validity through real-world memory assessment

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Best app on earth! no words because it’s too good

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

very reliable app to help and grow your ideas of Maths, English and other related topics in your works. please use this app if your struggling in areas, this app is key for that. wish I'd of done a review before. and it's also free so don't worry about that.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.

THE QUIZES AND FLASHCARDS ARE SO USEFUL AND I LOVE THE SCHOOLGPT. IT ALSO IS LITREALLY LIKE CHATGPT BUT SMARTER!! HELPED ME WITH MY MASCARA PROBLEMS TOO!! AS WELL AS MY REAL SUBJECTS ! DUHHH 😍😁😲🤑💗✨🎀😮

This apps acc the goat. I find revision so boring but this app makes it so easy to organize it all and then you can ask the freeeee ai to test yourself so good and you can easily upload your own stuff. highly recommend as someone taking mocks now
