Retrograde amnesia= loss of memories for events that occurred prior to an injury - Anterograde amnesia= loss of memories for events that occur after an injury - Patient H.M.= suffered from epileptic seizures and had hippocampus removed and developed anterograde amnesia Three Key Processes in Memory 1. Encoding= getting/forming information (i.e. keyboard) a. Attention= focusing awareness on a narrowed range of stimuli or events i. Selective attention= a filter of attention; paying attention to one thing at a time; critical ii. Divided attention= focus on two or more inputs simultaneously 1. Inhibits memory formation 2. Task-switching b. Levels of Processing i. Shallow processing: structural encoding= structure of stimulus ii. Intermediate Processing: phonemic encoding= what a word sounds like iii. Deep processing: semantic encoding= meaning of verbal input c. Ways to improve encoding: maintenance/rehearsal, elaboration, visual imagery, motivation to remember, mnemonic devices (link method/method of loci) 2. Storage= maintaining encoded information overtime (i.e. hard disk) a. Sensory memory→ Short-term memory→ Long-term memory i. Sensory memory= info. preserved in its original sensory form for brief

    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.
