Week 6 Thursday, October 10, 2024 11:32 AM Fall 2024 - PSYC3330... Memory and Attention Page 1 - How time is allocated or…. - What are u doing during learning? - Passive vs active (recall) - Focused/sustained attention - Other studies: number of writing skills taking classes - best predictor for retaining/recalling later on - Instructor feedback also imp. Memory and Attention Page 2  - Neurons more differentiated - How should allocation be? - All at once vs. spaced - Stabilizing memory trace and independent of hippocampus Distributed practice --> tome interval --> lag effect (if lag too long, detrimental) --> non-monotoive lag effect - Also called: distributed learning effect - Illusion of knowing happens more w/ massed practice - Meta cognition + meta memory skills - --> reflecting on own thinking, thinking about aspects of memory - Massed still has some benefits Memory and Attention Page 3  s- study t= test N = nonrecalled - 1st group study + recalled all 40 pairs - Type of feedback is important - If u don’t go back and relearn incorrect answer, you'll consolidate incorrect answer Memory and Attention Page 4 - "lawnchair" larry - Created own aircraft , couldn’t be pilot - Ballons on lawnchair - Plan to come down: shoot balloons down Memory and Attention Page 5  - Stimulation of reward pathway: - Novelty - drugs Memory and Attention Page 6  - 4 types of learning - Intention stablizies memory trace - Observed this effect not only in humans but other animals - Obvious/standout - If things aren't stored anywhere else in brain, it will be lost, so memory is transferred so they can be recalled independently recalled Memory and Attention Page 7  - Implicit association that’s learned - pavlovian - Implicit associate learning - Disliking/liking stimulus - Implicit that’s enhanced by repeated practice - Implicit cognitive skills, habits etc - This is how addiction can occur - Temporal component Cs-us - Extinction learning Cs-NoUs - Bell means no food - Both go thru A E C R - Compete w/ each other - Memories get stronger over time - Bell keeps ringing, animal forgets? Original association - Original association tends to be the stronger one - Is it rlly forgetting? - Weakened association - Rlly strong for food aversions - Second order conditioning - Pair bell with something else (ie light) - Light will elicit condition response Memory and Attention Page 8  - Toothpaste and then - Similar 2 classical conditioning after a slide of positive product - More preferred toothpaste - Don’t require conscious memory - Routines etc - If memory trace is actively repeated - Less energy required 2 activate - Perceptual priming - sensory - Conceptual priming - abstract/concept Memory and Attention Page 9 - Learning HOW to do something - All the knowledge u have arises from connections in neurons - Freud first said "law of association by simultaneity" - Neurons that fire together wire together - Excitability of neurons can be modified by experience? Memory and Attention Page 10 - Context neural - Importance of long term learning Memory and Attention Page 11  - Anti- nmdar encephalitis - Bodies produces antibodies that attack these receptors - Coincidence receptors - Causes inflammation in brain - "binding" things together - Important ** - Midterm - Voltage change - Expel plug and calcium comes in - "enhanced synaptic connectivity" - Pre synaptic neuron - Post synaptic neuron - Specialized receptors - "coincidence detectors" - Detect things that r co occurring @ same time - "neurons that fire together wire together" - Associative learning occurring thru this Memory and Attention Page 12  - Modifiable by experience - Stored stabilized recalled - Diaschisis - Hemispheric Asymmetry encoding and retrieval - H.E.R.A - Due to cerebral lateralization - Left side: encoding - Ride side: retrieving information - Encoding but unable to retrieve (maybe) - In declarative/episodic form - Effort activating - Diagnosis bias - Expecting to find certain cues - So when it comes to medical field, you'll diagnose with whatevers easier/u specialize in - More likely to be activated easily and better - Literally more neurons for memory - Enhanced synapsis activity, parahippocampal cortecx etc prefrontal cortex - Specialized cells in hippocampus Memory and Attention Page 13  - Schema - Framework of how to understand/connect things - Linking 2 previous learning - Encoding: - Logical connection - Concrete words r 1) visual appearance way its written 2) semantic - Metacognition VS ball - Abstract words- visually - M.O.V.E - Meaningful - Organization - Visualization - Elaboration - No practical skills - U need both not just factual knowledge - Testing incidental learning - Non intentional Memory and Attention Page 14  - Each time its recalled, memory is strengthen: reconsolidation - Weakened: extinction - Helps keep them in wm, manipulate it then put it into long term memory - Putting things into Schemas to make sense of new things - Remember more if its organized/logically structured Memory and Attention Page 15 Memory and Attention Page 16 - Episodic memory- item/event that needs to be recalled has this - Semantic memory is independent of this - Amygdala - emotional significance of episodic memory - Integrating episodic experience w/ existing memories - Lower middle Memory and Attention Page 17 Memory and Attention Page 18 Memory and Attention Page 19 - Can occur within a short period of time Memory and Attention Page 20 - Hippocampal dependent - Hippocampal independent Memory and Attention Page 21
