6
Q

Judging a situation based on how similar the aspects are to the prototypes the person holds in their mind. (think stereotypes)

ex. Like thinking everyone from private schools is preppy, or someone with glasses is nerdy, or a blonde is not smart.

7
Q

Judging a situation based on examples of similar situations that initially come to mind.
Vivid examples in the news often cause an availability heuristic.

ex. More Americans die from diabetes and stomach cancer than from homicide and car accidents, by a ratio of nearly 2:1. Many people guess homicide and car accidents, largely due to the publicity they receive and in turn, their availability in the mind.

25
Recall is stronger when a subject is present in the same environment in which the original memory was formed ex. need to sharpen pencil, go downstairs to do it and forget, remember when you go back upstairs
Context Dependent Memory
26
Remember memories that align with the mood you are in ex. you get into your top college, you are excited/happy, you remember the time you won the state championship
Mood Congruent Memory
27
The steps of the memory process
encoding, storage, retrieval
28
The processing of getting information into the memory system.
Encoding
29
The retention of encoded material over time.
Storage
30
The process of getting the information out of memory storage.
Retrieval
31
A split second holding tank for ALL sensory information. - large capacity, contains sensory information, very brief retention of images Iconic Memory - Visual (holds for 1-2 seconds) Echoic Memory – Auditory (holds for 2-5 seconds)
Sensory Memory
32
The stuff we encode from the sensory goes to here. Events are encoded visually, acoustically, or semantically (through meaning). Holds about 7 (plus or minus 2) items for about 20 seconds. AKA Working Memory - limited capacity, brief storage of items, involved in conscious processing of information
Short term memory
33
Unlimited storehouse of information. Explicit memories = the facts and experiences we can consciously know and declare (aka declarative memories) Implicit memories (aka procedural memory) = automatic processing, happens without our awareness (aka non-declarative memories) - unlimited capacity, storage thought by some to be permanent, information organized and indexed
Long term memory
34
Examples of encoding errors (using Snow White) naming the 7 dwarfs = doc, dopey, grumpy, sneezy, sleepy, happy, bashful
Semantic encoding error - i.e. know there’s a very smart dwarf, but can’t remember it’s Doc Acoustic encoding error – i.e. remember Dumpy or Bumpy but not Grumpy Visual encoding error – i.e. all dwarfs have beards, but Dopey doesn’t Structural encoding error – i.e. all dwarfs names ending in “y”
35
you must retrieve the information from your memory ex. fill-in-the blank or essay tests
Recall
36
you must identify the target from possible targets ex. multiple-choice tests
Recognition
37
Eyewitness recall
Humans are bad eyewitnesses Elizabeth Loftus: - Framing of questions can lead to false memories (“leading questions”) - Reconsolidation = every time you retrieve/recall a memory it can change
38
Forgetting
Decay = what we learn we can quickly forget Proactive interference = old interferes with new Retroactive interference = new interferes with old
39
Mnemonic Device to remember types of forgetting
P.O.R.N. Proactive Old interferes w/ new Retroactive New interferes w/ old
40
How to help remember
- Chunking - Mnemonics (ex. Peg words) - Spacing effect - Make things personally meaningful (shallow processing vs deep processing) - Rehearsal (studying/going over it again)
41
Spacing effect
- do not cram - learning is more effective when study sessions are spaced out - shows that more information is encoded into long-term memory by spaced study sessions
42
memory loss before accident/event, more common, usually temporary
Retrograde amnesia
43
memory loss since accident/event (hippocampus damage - can't form new memories post accident), less common
Anterograde amnesia
44
forget where you heard something from
Source misattribution/Source amnesia
45
storage decay over time
Transience
46
tip-of-tongue phenomenon
Blocking
47
not paying attention
Absentmindedness
48
Hippocampus and memory
Needed for new memories ( ex. Clive had hippocampus damage so can't remember anything) Part of limbic system Lateralized (different parts = different functions) Active during delta waves sleep while memories are processed Neurons in hippocampus release acetylcholine, needed for memory, Ach enables learning and memory, Alzheimer’s is caused by Ach producing neurons deteriorate
49
Cerebellum and memory
In hind brain (looks like a leaf) balance and coordination Needed for conditioned responses and procedural memories (along parts of limbic system) - Ex. Clive Wearing could still remember how to play the piano
50
Frontal lobes and memory
Works in conjunction with part of the limbic system Needed to stimulate working memory (aka short term memory) Left and Right lobes process different memories
51
Amygdala and memory
Emotional limbic system Big role in the formation and storage of unconscious memories Especially very emotional/stressful ones can be seared into memory
52
Automatic memory processing
implicit memories (nondeclarative) without conscious recall processed in cerebellum and basal ganglia - ex. space and time and frequency (where you ate for dinner yesterday), motor and cognitive skills (riding a bike), classical conditioning (reaction to the dentist's office)
53
Effortful memory processing
Explicit memories (declarative) with conscious recall Processed in hippocampus and frontal lobes - ex. facts and general knowledge (this module's concepts), personally experienced events (family holidays)
54
our spoken, written, or gestured work, is the way we communicate meaning to ourselves and others.
Language
55
Phonemes
the smallest distinctive sound ex. bat, has three phonemes b · a · t ex. chat, has three phonemes ch · a · t
56
Morphemes
smallest unit that carries meaning Milk = milk Pumpkin = pump . kin
57
Nature of language
Language Acquisition– Noam Chomsky (linguist during the time of Genie, came up with the idea of critical period) Mastery of language early w/out formal education Infants have entire range of phonemes Learn nouns first Overgeneralizations – I goed to the park (instead of went) Speed of learning (super high when you are young)
58
Nurture of Language
Learn parent’s language – “lose” phonemes not in language - ex. A Christmas Story ( fararara instead of falalala due to Chinese language) Models parent
59
Whorfian Hypothesis
Linguistic Determinism: Benjamin Lee Whorf One’s language influences the way one thinks - Today deemed to harsh, as we all think about things that have no words
60
an impairment in speech comprehension and/or production
Aphasia
61
Explicit memories
the facts and experiences we can consciously know and declare (aka declarative memories) Processed in hippocampus and frontal lobes - ex. facts and general knowledge (remember items on your shopping list or your friends' birthdays), personally experienced events (family holidays)
62
Implicit memories
(aka procedural memory) automatic processing, happens without our awareness / without conscious recall (aka non-declarative memories) processed in cerebellum and basal ganglia - ex. space and time and frequency (where you ate for dinner yesterday), motor and cognitive skills (riding a bike), classical conditioning (reaction to the dentist's office)
