Psychology Notes Exam 2 Module 20 The foundations of Memory o Memory- The process in which we encode, store, and retrieve information Encoding - The initial process of recording information in a form usable to memory Storage - Maintenance of material saved in memory. If the fact is not stored in the right way then it cannot be recalled later when you need it. Retrieval - Material that is in your memory has to be located and brought up to be useful. Trying to think of something that you think you know but you can’t think of it at that exact time is because you can’t retrieve the information that you learned at an earlier time. These processes remind of us a computer because the encoding is like the keyboard (this is how you record the information), storage is like the hard drive (this is where what you recorded is kept), and retrieval is like the software that locates the information and brings it to you when you need it. All three of these have to work for you to have success in what you need. o Sensory Memory - The initial, momentary storage of information lasting only for an instant. Precise, they store nearly an exact replica but are very brief Examples: Flash of Lighting, snap of a twig Can only store memory for a short amount of time and if it doesn’t get passed to short term memory then it is lost forever. Sensory Memory is just like the experiment I did where numbers flashed on the screen for a very short period of time and then I was asked to repeat the numbers I had just seen. Although I knew I saw 8 numbers I was only able to accurately remember about 3. This was due to that I knew there were more numbers but by the time I could verbalize them, the memory of the other numbers faded away. When the next 8 numbers appeared I completely forgot the previous 8. o Short Term Memory- The memory store in which information first has meaning although the maximum length of retention there is relatively short. If we can possibly retain some of the information that we see then it is considered short term memory. This is the memory store in which information first has meaning, although the length of retention is very short.

Short term memory is stored in chunks . Short term memory can hold seven items with variations up to + or – two chunks. Chunk - a meaningful grouping of stimuli that can be stored as a unit in short term memory. If something is given to you in one big line rather than in seven chunks each with three letters, it is a lot harder for you to remember . Short term memory usually stays with you for 15-25 seconds unless it is transferred to Long term memory. The transfer of memory from short term to long term depends on Rehearsal
