Unformatted text preview: Introduction to Cognitive Science PSYCH 1102/COGST 1101/LING 1170/ PHIL 1910/CS 1710 Topics: Learning The role of the hippocampus Hippocampus abdominalis Outline Types of memory Some psychologists really like flowcharts Amnesia “Now” is “now” sir Learning What happens in STM, stays in STM, (unless you learn it). What does the hippocampus do? Learning at the cellular level Types of memory Some psychologists really like flowcharts Implicit memory : Information that is learned without knowing that we’ve learned it Explicit memory : Information that we remember learning We can make more distinctions than that! Types of memory Long-term memory Short-term memory Explicit memory/ Declarative memory Implicit memory/ Non-declarative memory Non- associative memory Classical conditioning Perceptual memory Procedural memory Semantic memory Episodic memory Specific personal experiences Facts & world knowledge Motor skills Perceptual cues S-R pairings Habituation Types of memory Types of memory For our purposes the distinction is: Perceptual Memory Information stored as the current activation in the eyes & ears and early perceptual systems Has a lifespan of 1/2s – a few seconds depending on perceptual domain Short Term Memory (STM) The information we are actively thinking about right now which has a lifespan of seconds to minutes, unless actively refreshed Long Term Memory (LTM) Information we can dig up if we need to, which has a lifespan as long as we do, baring TBI Types of memory Types of memory Some evidence for different types of memory Word recall task Present a list of words (about 1 per second) After last word recall as many as possible Free recall task Types of memory Serial position curve Primacy effect The first few items in a list are easy to recall Putting items into LTM requires time and attention Items early in the list get more time and attention Items later in the list get less attention Types of memory Serial position curve Recency effect The last few items in a list are easy to recall Items we are currently working with are in STM We can only keep a few items in STM, so we remember those few Types of memory...
