Transcript of Fact or Falsehood?
Fact or Falsehood? Memory storage is never automatic; it always takes effort.
– False The day after you are introduced to a number of new students,
you will more easily recall the names of those you met first.– True
Memory aids (e.g., those that use imagery and devices for organization) are no more useful than simple rehearsal if information.– False
Only a few people have any type of photographic memory.– False
Although our capacity for storing information is large, we are still limited in the number of permanent memories we can form.– False
We store information in memory as libraries store their books, that is, in discrete, precise locations.– False
When people learn something while intoxicated, they recall it best when they are again intoxicated.– True
The hour before sleep is a good time to commit information to memory.– True
Repeatedly imagining a nonexistent even can lead us to believe it actually happened.– True
Children typically will repress any memory of having seen one of their parents being murdered.– False

MEMORY AND HOW IT WORKS
Memory: Learning that has persisted over time
To remember an event, we must successfully–Encode – get information into our
brain–Storage – retain information–Retrieval – getting information back
out
HOW WE ENCODE Parallel processing – doing many things at
once We automatically process information about
space, time, frequency and well-learned information
Effortful processing – encoding that requires attention and conscious effort– Can be boosted through rehearsal –
conscious repetition– Overlearning increases retention
HOW WE ENCODE -CONT-
Spacing effect – we retain information better when our rehearsal is distributed over time– Spaced study and self-assessment beat
cramming Serial position effect – tendency to
recall best the last and first items in a list– Primacy effect – best recall for first items– Recency effect – best recall for last items

WHAT WE ENCODEVisual encoding – encoding of images
–Mnemonics – memory aids that use vivid imagery and organizational devices
Acoustic encoding – encoding of sounds
Semantic encoding – encoding of meaning, including meaning of words

EXAMPLE
A newspaper is better than a magazine. A seashore is a better place than the street. At first it is better to run than to walk. You may have to try several times. It takes some skill but is easy to learn. Even young children can enjoy it. Once successful, complications are minimal. Rain, however, soaks in very fast. Too many people doing the same thing can also cause problems. One needs lots of room.
LEVELS OF PROCESSING
Memorize as many digits as you can (in order)

chunking - organizing items into familiar, manageable units
Memory Olympics
SHORT TERM VS. LONG TERM MEMORY
Short-Term Memory– Limited, unless actively processed– Capacity of 7 digits +/- 2– Better for random numbers than
random letters– Better for sound than sight
Long-Term Memory– Limitless
STORING MEMORIES
Flashbulb memories – clear memory of an emotionally significant moment or event– Strong emotional experiences = strong,
reliable memories Amnesia victims
– Have implicit memory – how to do something
– But no explicit memory – memory of facts and experiences that one can consciously know and “declare”

RETRIEVAL: GETTING INFORMATION OUT
Priming - often unconscious activation of particular associations in memory– “memoryless memory”
Context effects– Easier to remember things in the same context
you learned them– Déjà vu - sense that “I’ve experienced this before”– Mood congruent memory - tendency to recall
experiences that are consistent w/one’s current good or bad mood

WHY WE FORGET Three sins of forgetting
– Absent-mindedness - inattention to details– Transience - storage decay over time– Blocking - inaccessibility of stored info
Three sins of distortion– Misattribution - confusing the source of the
information– Suggestibility - lingering effects of misinformation– Bias - belief-colored recollections
One sin of intrusion– Persistence - unwanted memories
FORGETTING
Course of forgetting is initially rapid, but levels off w/time
Interference– Proactive interference - something you learned
earlier disrupts your recall of something you experience later
– Retroactive interference - new information makes it harder to recall something you learned earlier
Freud believed we repress - banish anxiety arousing thoughts, feelings and memories

PROACTIVE AND RETROACTIVE INTERFERENCE
FAULTY MEMORY CONSTRUCTION
Misinformation effect - incorporating misleading information into one’s memory of an event
Source amnesia - attributing the wrong source to an event we have experienced, heard about, read about or imagined
False memories feel as real as true memories Unreliable memories
– Things happening before age 3– Memories “recovered” under hypnosis or drugs
