2
Learning that has persisted over time; it is information that has been acquired, stored, and can be retrieved.
3
Encoding: processing of information Storage: retaining information over time Retrieval: getting it out of storage
5
Sensory memory Short-term memory Long-term memory Outdated, but still a useful starting point
6
Iconic— 250 milliseconds Echoic— 2 seconds Tactile Taste Olfaction Holds sensory information in the raw, unprocessed form If we attend to it, it is encoded in short- term memory
7
Uncertain conclusions— verbal information an image others believe it is something more abstract Rule of 7 Info is gone in 30-60 seconds if not attended to. Connection b/w sensory and LTM “Sometimes google replaces rehearsal”
8
Memory occurs in the synapse via neural connections LTP—Long term potentiation Hippocampus
10
Automatic processing Describe your day so far… Parallel processing Implicit memories (non- declarative) Meditation Effortful processing Explicit memories (declarative) What you do all of the time for school
11
Parallel processing— dejavu (theory) Working memory getting mixed up w/ automatic processing
12
Chunking Spacing Effect Testing Effect— practice recall Serial Position Effect Primacy effect Recency effect Mnemonic devices Peg word system Roy G. Biv Hierarchies (i.e. text structures )
13
Semantic encoding Personal connection Shallow = writing things down w/out thinking about them
14
Demonstration #1 Two groups Whatever group remembers the most words wins. Demonstration #2 Remember the list of words in order Two rounds
15
Rehearsal—Verbal Best for phone #s, passwords, SS #s, learning alphabet, etc… Elaboration—visual (or otherwise) connection to something you already know 1) Relatively permanent 2) Assumed to be unlimited 3) Contains different types of memories
16
1) Explicit (Declarative) Semantic—meaning Episodic—personal Write an example of each memory in your notes 2) Implicit—unaware of retrieval (nondeclarative) Procedural--(i.e., riding a bike, tying shoes, etc…) Emotional—love, hate, fear, anxiety, etc…
17
Hippocampus /Frontal Lobe= explicit/declarative Cerebellum/basal ganlia /Amygdala= implicit/ nondeclarative Figure 32.5 in text
18
ANTEROGRADE AMNESIARETROGRADE AMNESIA Inability to transfer new information from short-term into long term Clive Wearing Clive Wearing 50 First Dates Memento Inability to retrieve information that was acquired before a particular date, usually the date of an injury or operation Bourne movies The Vow
20
Recall Recognition Relearning— Ebbinghaus Priming— unconscious associations
21
ENCODING SPECIFICITY PRINCIPLE Context matters! State dependent memory This is why you stare at me while taking a test sometimes Don’t study in your bed!!!!! Method of Loci— “mental walk”
22
1) Transience Proactive interference— when information learned earlier impairs memory for information acquired later. Retroactive interference— when information learned later impairs memory for information acquired earlier P: proactive O: old R: retroactive N: new
23
2) Absentmindedness—lapse of attention results in memory failure
24
3) Blocking—failure to retrieve information that is available—tip of the tongue phenomenon “it starts with…”
25
4 ) Memory misattribution—assigning a recollection or an idea to the wrong source, aka…source amnesia false memories false memories
26
Try to remember as many as you can of list of words I read aloud to you.
27
#5) Suggestibility—the tendency to incorporate misleading information from external sources into personal recollections false memories false memories 1992: El AL cargo Plane, Amsterdam New Jersey SC New Jersey SC Elizabeth Loftus—TED Elizabeth Loftus—TED Eyewitness Testimony Eyewitness Testimony
28
#6) Bias—distortion of memories due to present knowledge/beliefs/feelings We remember the good and forget the bad We like to think of ourselves as consistent so we diminish the memory of change in ourselves—cognitive dissonance Confirmation Bias
29
#7) Persistence—the intrusive recollection of events that we wish we could forget, usually tied to a heightened level of emotion Embarrassing MomentsFlashbulb Memories
30
Alfred Adler Present determines past What is your earliest memory—write it down or draw it in detail… Are memories based on present mood and situation?
31
Autobiographical Memory Autobiographical Memory
32
What does it mean to lose your memory? Are you still the same person to yourself and to others? Do you still have your identity?
