Q

Operant Conditioning

A 
Utilizes consequences (reinforcement, punishment) to drive behavior.

Q

Bandura’s Social Cognitive Theory

A

A-Attention
M-Memory
I-Imitation
M-Motivation

23
Q

Reinforcement

A

Increases further instances of behavior
Positive: Adding (Money) (Hippocampus)
Negative: Removes undesirable stimulus following correct behavior (Seatbelt sign) (Amygdala)

24
Q

Punishment

A

Decreases further instances of behavior
Positive: Adding (Ticket)
Negative: Removing (License)

25
Flashbulb Memories
Highly emotional memories that are very vivid
26
Long Term Potentiation (LTP)
Example of synaptic plasticity (the ability of neurons to change their strength) Neurons communicat and same levels of presynaptic activity lead to greater post synaptic activity
27
Decay in Learning
Ebbinghaus (Rate of word forgetfulness) | When info is not retrieved for a long time, the neural connections become weaker. "Use it or lose it"
28
Interference
Retroactive: New piece of learning impairs old learning Proactive: Something you learned in the past interferes with your ability to remember new one.
29
Dementia
Excessive damage to brain tissue Most common: Alzheimers Decline in memory & other cog functions that impairs daily life
30
Korsakoff's Syndrome
Lack of vitamin B1 or thiamine Damage to brain leads to memory loss, loss of balance, reduced cognition Severe memory loss
31
Confabulation
Makes up stories to fill in the gaps during memory loss in korsakoff's syndrome
32
Nonassociative Learning
When an organism is repeatedly exposed to a stimulus
33
Associative Learning
Process of learning in which one event is connected with another - Classical Conditioning - Operant Conditioning
34
Observational Learning
Social learning or learning through observation/watching/imitating others
35
Modeling
Mechanism behind observational learning. You model and then you imitate.
36
Reciprocal Determinism
the theory set forth by psychologist Albert Bandura that a person's behavior both influences and is influenced by personal factors and the social environment.
37
Reflexive Movements
Primitive, involuntary movements (0-1 years) | Genetic
38
Rudimentary Movements
0-2 Years Serve as the 1st voluntary movements Dictated by genes
39
Fundamental Movements
2-7 Years Fundamental movement Highly influenced by environment
40
Specialized Movement
Transitional substage: Combine movements | Application substage: Apply these to a certain activity
41
Lifelong application stage
Take all movements learned and apply to various things in life
42
Infantile Amnesia
The age before which we remember nothing (3.5 years) | Learning still happens during this stage
43
Harlow Monkey Experiment
Monkeys are attracted to comfort when young, not nourishment. Contact comfort was more important.
44
Mary Ainsworth
Experiment with securely attached and insecurely attached infants
45
Securely attached infants
In the presence of mother they play and explore, get distressed when mother leaves and seek comfort when she returns
46
Insecurely attached Infants
Latch on to mother, when she leaves they cry or act indifferent and return.
47
Parenting Styles
Authoritarian - Too strict without reason Permissive - Not strict at all, kids run show Authoritative - "Best" parenting style
48
Serial Positioning Effect
Effect seen when memorizing a list of sorts, that you remember the first few and last few. This is the recency and primacy effect.
49
Prospective Memory
Remembering to do things in the future
50
Misinformation effect
Tendency to misremember
51
False memory
Repeatedly imagining something can create inaccurate recollections for an event.
52
Avoidance behavior
A behavior carried out to 'avoid' unpleasant stimulus even when there is nothing to avoid sometimes. Rat jumping to avoid shock.
53
Echoic Memory
Short term memory for sound
