Lecture #27 How Memory Works Part I – Encoding – the process of getting information into memory Part II -- Storage – retaining information in the brain -3 types of storage: sensory memory, short-term memory, long-term memory 1) Sensory Memory : a very brief memory of all the details of a scene -you can remember every detail for a very brief moment, but it is very fragile -there is a different sensory memory for every sense iconic memory - visual sensory memory (e.g., after a lightning flash you momentarily retain a vivid mental image of its ragged edges. echoic memory - auditory sensory memory -The information that you pay attention will be transferred to short-term memory 2) Short-term memory is a working memory -whatever you are thinking about at the moment -limited in capacity -not permanent - must rehearse info or you will lose it 3) Long-term memory -relatively permanent and limitless storehouse of the memory system -rehearsal of info in STM transfers the info into the LTM -phenomenon that shows the difference between STM and LTM: serial position effect -e.g. introduced to lots of different people, when the evening ends, how many you can remember? - you remember the first and last people very well, but not the people in the middle immediately after the task | * * recall | * * | * * | * * * .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
