Q

How do you change your behavior?

A
  1. State a realistic goal in measurable terms & announce it
  2. Decide how, when, and where
  3. Monitor how often you will engage
  4. Reinforce the desired behavior
  5. Reduce the rewards gradually

Q

What are some examples of aversion?

A

When you eat bad food (more likely to develop aversion to bad food you ate in general, not the place you ate it from)

Instead of killing wolves, it works to feed the lamb laced with poison so the wolves develop aversion to sheep

25
Relearning
Time saved when learning something again (we remember more than we can recall)
26
Encoding
Getting info INTO brain
27
Storage
Memory stays OVER TIME
28
Retrieval
Getting info OUT of brain
29
What is the order of memory retrieval?
1. Sensory input 2. Sensory memory 3. Encoding 4. Working/short term memory 5. Encoding 6. Long-term memory storage
30
Chunking
Familiar manageable units (automatic) (the way we memories phone number)
31
Mnemonics
Way to remember (PEMDAS)
32
Hierarchies
Dividing info based on topic and getting increasingly more specific (like a chart/tree)
33
Level of Processing: Shallow
Encoding on a basic level based on structure or appearance
34
Level of Processing: Deep
Encoding semantically based on meaning (yields better retentions)
35
What are the levels of processing?
1. Structural (shallow): What does the word look like? 2. Phonetic: What does the word sound like? 3. Semantic (deep): What does the word mean?
36
Karl Spencer Lashley
Studied rat learning via mazes Learned that only large lesions produced deficits Deficits were similar no matter where the lesion occurred
37
How do we retrieve memories?
Brain regions send info to PFC (working memory)
38
What lobe is used to recall a password?
Left frontal lobe
39
What lobe is used to recall a visual party scene
Right frontal lobe
40
What is included in the EXPLICIT memory system?
Frontal lobes and hippocampus Semantic or episodic Memory consolidation
41
Memory consolidation
Neural storage of long term memories Happens during sleep
42
Spacing studying
More chances for sleep to consolidate memories
43
What is included in the IMPLICIT memory system?
Cerebellum (forms and stores, conditioned reflexes) Basal ganglia (procedural memories, receives info but doesn't send) Skills and newly conditioned associations
44
Synaptic changes
Experiences and learning increases the number of synapses (cell connections) in the brain
45
Long term potentiation
Physical basis for memory An increase in cell firing potential after brief and rapid stimulation You can wipe out current memories, but not old ones
46
Encoding Specificity Principle
Cues specific to event or person will most effectively trigger your memory
47
State-Dependent Memory
Mood impacts WHAT and HOW we remember
48
Encoding failure
What you don't notice
49
Storage Decay
Memory durability Happens rapidly then levels off over time
50
Retrieval failure
Tip of the tongue Stems from interference
51
Source amnesia
Faulty memory for where, how, when, or who (specifics) Thinking a buzz feed article is from a scientist
52
True vs. false memories
We more easily remember the gist of things rather than the specifics False memories are socially contagious through storytelling
53
How can you improve memory?
- Rehearse (spacing & testing) - Make it meaningful (associations) - Retrieval cues activate (context & state dependent) - Mnemonic devices - Minimize interferences - SLEEP MORE - Test yourself (spacing and testing)
54
Prototype model
Instances of a concept are understood/stored as a variation of a prototype (ideal example) of that concept Look for a "family resemblance" Prototypes can be misleading when applied to people
55
Fixation
Using a prior strategy only
56
Functional fixedness
Fixated on usual functions (the inability to realize that something known to have a particular use may also be used to perform other functions)
57
Culture bias in testing
Raven Progressive Matrices Test (bias reduced rather than bias free)
58
Genetic influences of intelligence
Possibly 1000+ intelligence genes (alleles) Heritability (group statistic)
59
Environmental influences on intelligence
Omega 3 fatty acids Early childhood education Reading w/ parents
60
Sternberg's Triarchic Theory
1. Analytical 2. Creative 3. Practical
61
Analytical intelligence
Analyze, judge, evaluate, compare, contrast
62
Creative intelligence
Create, design, invent, originate, imagine
63
Practical intelligence
Use, apply, implement, put ideas into practice
64
Infinite generativity
The ability to produce an endless number of meaningful sentences
65
Semantic memory
Facts, knowledge, concepts (Paris is the capital of France)
66
Episodic
Memory for specific events (I graduated high school in 2022)
67
Implicit memory
Unconscious retrieval
68
Explicit memory
Conscious retrieval
69
In shaping behavior, first...
build on natural already existing behaviors
70
Operant conditioning
A type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher A reinforcer or punisher is given AFTER a behavior
71
Repressed memories are...
highly debated
72
Many convicted people based on witnesses have been cleared with
DNA
73
Classical conditioning
A signal is placed BEFORE a reflex
