A Little Neuroanatomy Current Lecture Memory Processes o Sensory Memory (SM) Preserves information in its original sensory form for a brief time usually only a fraction of a second SM holds information in a literal form - Allows our perceptual processes time to work - Ionic: visual memory - Echoic: auditory memory SM allows us to decide if brief sensory input is important enough to pay attention to o Short Term Memory (STM) Limited capacity store that can maintain unrehearsed info for up to ~20 seconds Rehearsal - The process of repetitively or thinking about information - Maintenance: simple repetition of info in memory These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- Elaborative: linking of info to additional memories for increased retention Short-term or working memory - The magic number 7+- 2 o People can generally remember only about 7 items of unfamiliar material - Chuncking can increase your STM capacity o A group of familiar stimuli stored as a single unit o Long Term Memory (LTM) LTM- an unlimited capacity (?) stored that Cn hold information over lengthy periods of time - Forgetting may occur because people simply cannot from LTM Levels of processing - Memories endure when information is processed more deeply o State- or Context- dependent memory The context which info is acquired may retrieval - What did I come here for? Godden and Baddeley, 1975- Scuba divers that learned under water or on land - Later tested in the same or different context “Context” can be self-generated If you learn something while drunk you’ll have better recall if drunk than sober A little neuroanatomy o Hippocampus involved in the consolidation of memories Consolidation conversion of info into durable memory codeso Patient HM Removal of temporal lobe to prevent epilepsy Memory for events before surgery is normal, and STM is normal Cannot transfer from STM to LTM to form new memories Cannot recognize people he sees every day, nor himself But….
