Higher Human Biology - Unit 3 Memory Mindmap & Revision Notes

The Memory Process: From Input to Storage
Memory involves three key processes that work together: encoding (taking in information), storage (keeping it safe), and retrieval (getting it back when needed). Think of it like your phone - you capture a photo, save it to your gallery, then find it later when you want to show your mates.
Sensory memory is your brain's first filter, holding all visual and auditory input for just 1-2 seconds. Most of this information disappears immediately unless it grabs your attention. It's like walking through a busy street - you notice everything for a moment, but only focus on what matters.
The short-term memory (STM) can typically hold about 7 pieces of information for a short period due to its limited storage capacity. However, you can boost this through chunking - grouping information into logical categories so it's perceived as less information and easier to retain. For example, remembering a phone number as three chunks (07700-900-123) rather than 11 separate digits.
Quick Tip: The serial position effect explains why you remember the first few items and last few items from a list better than those in the middle - use this when revising by putting the trickiest concepts at the start and end of your study sessions!

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.
