25
Observational learning
The is the process of learning by watching the behaviors of others
26
four phases of observational learning
attentional, retention, motor reproduction, and motivational
27
Bobo Doll experiments
proved that children can learn through observation and later imitating the same behaviors with a combination of environmental and cognitive processes. Its aim was to discover the extent of environmental influence on aggressive behavior.
28
Atkinson-Shiffrin 3 memory systems model
Sensory memory, ST memory, LT memory
29
Sensory memory
Sensory memory is the perception of sight, hearing, smell, taste, and touch information entering through the sensory cortices of the brain and relaying through the thalamus
30
Short-term memory
indicates different systems of memory involved in the retention of pieces of information (memory chunks) for a relatively short time (usually up to 30 seconds).
31
Long-term memory
Long-term memory refers to the transfer of information from short-term memory into long-term storage in order to create enduring memories. This type of memory is unlimited in capacity and stable—lasting for years or even a lifetime.
32
Transfer from STM to LTM
Short-term memories can become long-term memories through a process known as consolidation
33
working memory
Working memory is one of the brain's executive functions. It's a skill that allows us to work with information without losing track of what we're doing. Think of working memory as a temporary sticky note in the brain.
34
Elaborative rehearsal
Deep levels of encoding occur when information is encoded semantically, by relating it to other words, ideas, or previous knowledge
35
Shallow processing
shallow processing involves cognitive processing of a stimulus that focuses on its superficial, perceptual characteristics rather than its meaning
36
Deep processing
deep processing entails elaboration rehearsal, including interaction with the information through meaningful analyses (associations, visualizations, critical thinking processes) of the information
37
Mnemonics
the study and development of systems for improving and assisting the memory
38
Schema
a mental framework that helps individuals organize, process, and store information about their environment
39
Interference
occurs when some information makes it difficult to recall similar material
40
types of interference
proactive interference, in which old memories disrupt the retrieval of new memories, and retroactive interference, in which new memories disrupt the retrieval and maintenance of old memories.
41
episodic memories
Memories whose contents pertain to specific event's
42
Semantic memories
Memories whose contents relate to specific facts and pieces of meaningful information not based on personal experience
43
encoding specificity principle
idea that retrieval cues are only useful as long as they match the original context of how the to be remembered information was originally learned
44
amnesia
memory loss due to physical damage or problems in brain
45
retrograde amnesia
loss of memories prior to specific traumatic event such as blow to the had or certain other conditions
46
anterograde amnesia
inability to make new memories
47
Latent learning
Learning that has occurred but hasn`t been demonstrated yet
48
Attentional phase
A phase of social learning in which an observer watches a model doing something
49
Retention phase
phase of social learning in which an observer remembers what the model did and can imitate that response later
50
production phase
a phase of social learning in which an observer copies what the model demonstrated
51
motivational phase
a phase of social learning in which the observer obtain the same outcome as the model for the same response
52
learned helplessness
experiencing an aversive situation you cant control prevents you from learning to control other aversive situations
53
emotions
short lived feelings we have towards an object or situational event - these feelings often correspond to specific facial expressions adaptive responses to aid survival
54
motivation
the reason or reasons one has for acting or behaving in a particular way
55
james-lange thoery of emotions
Perceive stimulus, express the emotion the stimulus evokes, identify their emotions (emotions stem from interpretation of the body)
56
Cannon-Bard thalamic theory of emotions
perceive stimulus, simultaneously express emotion and identify emotion
57
action unit
Each emotion has a specific facial expression that we can detect involving movement of eyebrows nose mouth cheeks and eyes
58
2 factor theory
2 ingredients to emotion, arousal and cognitive appraisal
59
4 universal emotions
happy, anxious, surprise, disgust
60
Drive-reduction theory
need is determined by a combination of learning and a person physiology and need will intensity will be reflected in the intensity of responding
61
Yerkes and Dodson
found that arousal was interchangeable with whatever happens due to stimulus intensity in other words performance increases with mental arousal or stress up to a certian point
62
Darwin's three principles
variation, heredity, and selection. These principles explain how species change over time
63
Premack principle
highly desirable, more probable behaviors can be used to reinforce less desirable
64
response deprivation hypothesis
restricting one behavior will cause a deprivation of that behavior, which can be used to create a scenario where the possibility of being allowed the deprived behavior can potentially reinforce another behavior
65
establishing operations
Increase the effectiveness of reinforcers an evoke behavior related to them
66
abolishing operations
Decrease the effectiveness of reinforcers and decrease behavior related to obtaining them
67
Maslow's hierarchy of needs theory
a theory of motivation which states that five categories of human needs dictate an individual's behavior
68
order of Maslow's hierarchy of needs
physiological > safety > love/belonging > self esteem > self actualization
69
intrinsic motivation
ambitions stemmed from our own standards
70
Extrinsic motivation
ambitions/motivations imposed upon us
71
The facial feedback hypothesis
individuals' emotional experiences are influenced by their facial expressions example, smiling should typically make individuals feel happier
72
2 types of motivating operations
establishing operations and abolishing operations
73
Split brain
A type of surgery that cuts the connections between the two hemispheres of the brain to reduce frequency and severity of seizures
74
Corpus callosum
large band of axons that connect the two hemispheres of the brain
75
Hemispheric specialization
Refers to the idea that the two hemispheres in your brain (right and left) have differing functions
76
Conscious content
The subjective experiences of your internal and external world
77
States of consciousness
Refers to the different levels of arousal and attention an individual can experience
78
Attention
The process of selecting information from the internal and external environments to prioritize for processing
79
Passive attention
Occurs when the attentional priorities are set by bottom up information from the environment
80
Active attention
Occurs when attentional priorities are set by the top down goals of an individual
81
Selective attention
A form of attention that occurs when a person attends to some information while ignoring other information
82
Cocktail party effect
Describes a situation with selective attention, at a party a person can be engaged in a conversation and supress and ignore all the other information and stimuli around them
83
Dichotic listening task
An attention task where one stream of information is presented to one ear and a different message is played in the other, participant is asked to only attend one message and is later asked about the unattended message
84
Divided attention
Occurs when a person engages in two or more tasks at once
85
Inattentional blindness
Refers to the tendency to miss changes to some kins of information when your attention is engaged elsewhere
86
Alpha waves
Occur when a person is quietly resting and not doing any rigorous thinking most common occurrence of alpha waves is when a person is relaxed
87
Theta waves
The waves that appear on an EEG when a person is deeply relaxed or falling asleep
88

Brief bursts of activity that occur 2-5 times per minute occurring during non rem sleep
89
K complexes
A pattern of neural excitation followed by neural inhibition occurring during stage 2 sleep. Often triggered by unexpected noises
90
Delta wave
Brain waves that appear on an EEG when a person is deeply asleep these waves occur during stages 3-4 also known as slow wave sleep
91
Slow wave sleep
A broader name for sleep occurring in stage 3-4 During this stage recordings on EEG show delta waves
92
Rapid eye movement
A stage of sleep where narrative based dreaming occurs, during this stage EEG recordings become highly irregular and the sleeping persons eyes will move from side to side rapidly. Beta and theta waves are often common during this stage of sleep
93
Waves associated with respective sleep stages (Stage 1, stage 2, slow wave sleep, REM)
Theta waves begin in Stage 1 as brain activity begins to synchronize, followed by sleep spindles and K-complexes in Stage 2. Delta activity is characteristic of slow-wave sleep, with REM returning to desynchronized theta activity with additional blood flow to the visual association cortex
94
