(132 cards)
1
Q
Learning
A
Ways in which we acquire new behavior
2
Q
Habituation
A
Repeated exposure to the same stimulus
3
Q
Dishabituation
A
When we respond to an old stimulus as if it were new again; Restoration to full strength of a response that has become weakened by habituation
4
Q
Associated Learning
A
Learns an association between 2 stimuli or between behavior and response (done through operant or classical conditioning)
5
Q
Classical Conditioning
Respondent Conditioning
A
Learning the connection between different events.
A learning process that occurs when two stimuli are repeatedly paired; a response that is at first elicited by the second stimulus is eventually elicited by the first stimulus alone
6
Q
Operant Conditioning
Instrumental Conditioning
A
Learning the relationship between voluntary behavior and their consequences to alter frequency of behaviors
7
Q
Unconditioned Stimulus (UCS)
A
Classical Conditioning:
Response to a stimulus that is innate or reflexive (natural response)
8
Q
Conditioned Stimulus (CS)
A
Classical Conditioning:
Originally a neutral stimulus but after becoming associated or paired with an unconditioned stimulus will eventually trigger a reflexive response; Learned Stimulus
9
Q
Extinction
A
Removal of a response to a stimulus; behavior that used to bring a reward no longer does
Repeatedly presenting the Conditioned stimulus (CS) without the Unconditioned Stimulus (UCS)
10
Q
Spontaneous Recovery
A
After a period of time, producing a weak conditioned response (CR) after an extinction event
11
Q
Generalization
A
Stimulus similar to conditioned stimulus (CS) that produces the same conditioned response (CR)
12
Q
Discrimination
A
Learning to distinguish between two similar stimuli
13
Q
Neutral Stimuli
A
A stimulus that does not elicit any observable behavior other than focusing from an organism.
14
Q
Punishment
A
Operant Conditioning:
Reduces behavior
+ Punishment = adding an unpleasant consequence to decrease behavior
- Punishment = removing reward for doing bad to decrease behavior
15
Q
Reinforcement
A
Operant Conditioning:
Increases Behavior
+ Reinforcement = adding reward or incentive to increase behavior
- Reinforcement = removing something unpleasant to increase beavior
16
Q
Escape
A
Operant Conditioning: Negative Reinforcement (behavior removes something undesirable)
17
Q
Avoidance
A
Operant Conditioning: Negative Reinforcement (when given a warning that an aversive stimulus will occur soon, the organism will avoid the stimulus)
18
Q
Shaping
Differential Reinforcement
A
Operant Conditioning:
Rewarding increasingly specific behaviors (Sometimes while extinguishing others)
19

Fleeting impressions of sensory stimuli
34
Short Term Memory
< 1 minute (about 20 seconds)
Can remember about 7 (+/- 2) items

43
Retrieval
Recovering the stored information in memory at a later time
44
Relearning (Spacing Effect)
More time between session of relearning makes information harder to remember / recall
45
Context Effects
Remembering better by being in the same location where the information was learned
46
State Dependent Learning
Being in the same state (psychological or physical) of mind / conditions makes it easier to recall information
47
Serial Position Effect
Remembering the beginning and end of lists better than the middle
48
Neuroplasticity
Ability to make rapid neural connections in response to stimuli (this decreases with age)
49
Synaptic Pruning
Weak connections broken and strong ones bolstered
The process by which extra neurons and synaptic connections are eliminated in order to increase the efficiency of neuronal transmissions.
50
Long Term Potentiation
Strengthen synapses between nerves cells (connections) and increase receptor density in neurotransmitters
51
Alzheimers
Neurofibril tangles and plaques`create dementia (memory loss)
52
Korsakoff Syndrome

Agnosia
Loss of ability to recognize objects, people or sound
55
Interference
Retrieval error due to existence of similar information
56
Proactive Interference (Inhibition)
Old information interferes with new learning
57
Retroactive Interference (Inhibition)

58
Misinformation Effect
Remembering wrong information and details
59
Source Amnesia
Confusion between semantic (facts and concepts) and episodic (events and experiences) memory
60
Motivation
Purpose / driving force behind our actions
61
Extrinsic Motivation
Purpose for actions coming from outside oneself
62
Intrinsic Motivation
Purpose for actions coming from within oneself
63
Instinct Theory
People are driven to do certain behaviors based on evolutionary programmed instincts (innate, fixed patterns of behavior in response to stimuli)
64
Arousal Theory
People perform behaviors / actions to maintain an optimal level of arousal (psychological / physiological state of being awake and reactive to stimuli)
65
Yerkes Dodson Law
The law dictates that performance increases with physiological or mental arousal, but only up to a point
- Weak performance and Low arousal = highly cognitive tasks
- Weak performance and High arousal = physical endurance and stamina
- Strong performance and Medium arousal = Optimal
66
Drive Reduction Theory
| Theory of Motivation
Internal states of tension (innate physiological / biological need for something) that act as motivation to activate goal based behaviors to eliminate uncomfortable states
Primary = food, water, warmth, etc... motivate bodily processes for homeostasis
Secondary = emotional (not biological processes)
**Reinforcement occurs whenever a biological drive is reduced
67
Need Based Theory
| - Abraham Maslow
- Self actualization (fullest potential)
- Esteem (respect)
- Love/ Belonging (relationships)
- Safety (security)
- Physiological (basic needs - food, water, etc...)
The lowest needs must be met before you can move up the pyramid and this determines your motivation for behavior
68
Self Determination Theory
Behavior is motivated by:
- Autonomy; the need to be in control of ones actions and ideas;
- The competence to complete and excel at difficult tasks
- Relatedness; to feel accepted and wanted
69
Incentive Theory
Behavior is motivated by the desire to pursue rewards and avoid punishments
70
Expectancy - Value Theory
Motivation for behavior results from individual expectations of success in reaching the goal And degree to which they value succeeding at said goal
71
Opponent Process Theory
Repeatedly taking drugs will change the body's physiology resulting in tolerance (decrease in perceived drug effects over time)
72
Functionalist
Focusing on how the mind functioned in adapting to the environment
73
Ethology
Study animals in their natural environment (not in a lab)
74
Reflex
Unlearned response that is elicited by a specific stimulus
75
Unconditioned Response (UCR)
Classical Conditioning:
| A Natural response reflexively elicited by an unconditional stimulus
76
Conditioned Response (CR)
Classical Conditioning:
| Response that, after conditioning, is elicited by a conditioned stimulus; a Learned response
77
Forward Conditioning
The Unonditioned Stimulus (UCS) is presented after the Conditioned Stimulus (CS)
78
Acquistion
Describes the period during which an organism is learning the association of a stimuli
79
Backward Conditioning
Presenting the Conditioned Stimulus (CS) after the Unconditioned Stimulus (UCS); generally unsuccessful
80
Second - Order Conditioning
Neutral stimulus is paired with a Conditioned Stimulus (CS) not an Unconditioned Stimulus (UCS) like it usually is
Stage 1: Regular classic conditioning
Stage 2: (builds on stage 1) New Unconditioned Stimulus (UCS) is presented just before the Conditioned Stimulus (CS) is presented
Subsequent stages will build on the stage right before it
81
Sensory Preconditioning
2 Neutral stimuli are paired together and then one of the neutral stimuli is paired with an Unconditioned Stimulus (UCS)
Stage 1: Pair 2 Neutral stimuli
Stage 2: Pair the neutral stimuli with the Unconditioned Stimuli (UCS)
82
Contingency Explanation of Classical Conditioning
Classical conditioning is a matter of learning signals for the Unconditioned Stimuli (UCS)
The Conditioned Stimulus (CS) will become paired / associated with the Unconditioned Stimulus (UCS) because the CS is a good signal (has informative value) and a good predictor of the UCS
83
Blocking Explanation of Classical Conditioning
Condition is the association between the Conditioned Stimulus (CS) and the Unconditioned Stimulus (UCS); It may be impaired if during the condition the process of CS (A) is presented with a 2nd CS (B) that has already been associated with the UCS because no additional, useful information can be learned from the CS (A)
84
Law of Effect
If a response is followed by an annoying consequence, the animal will be less likely to emit the same response in the future
85
Discriminative Stimulus (SD)
Stimulus condition or situation that indicates that the organism's behavior will have a consequence
86
Partial Reinforcement Effect
Response is only reinforced part of the time; This method is more resistant to extinction
87
Fixed Ratio (FR)
Organisms receives reinforcement after a fixed number of responses
88
Variable Ratio (VR)
Organism receives reinforcement after a varying number of responses
(Reinforcement will average out at a specific #)
* *Very Resistant (VR) to extinction
* *Very Rapid (VR) Response rate
89
Fixed Interval (FI)
Organism will be reinforced on the first response after a fixed period of time has elapsed since the last reinforcement
90
Variable Interval (VI)
Organism will be reinforced for the first response made after a variable amount of time has elapsed since the last reinforcement
(There is an average time interval period)
91
Continuous Reinforcement Schedule (CRF)
Reinforcement after every correct response / behavior
92
Flooding
| Exposure Therapy
Behavior Therapy:
Person experiences an anxiety producing stimulus (feared object)
93
Implosion
Behavior Therapy:
Client imagines the fearful situation
94
Systematic Desensitization
Behavior Therapy:
Hierarchy of anxiety - producing situations coupled with the use of relaxation techniques
95
Counter Conditioning
Behavior Therapy:
During Desensitization an Individual cannot experience contradictory emotions (anxiety and relaxation) simultaneously
96
Behavioral Contract
Behavior Therapy:
Negotiated agreement between two parities that explicitly states the behavioral change that is desired and indicates consequences of certain acts
Useful in resolving interpersonal conflicts
97
Time-Out
Behavior Therapy:
Removing the client from the reinforcing situation before reinforcement can be received for the undesirable behavior; therefore the behavior will not be reinforced and will eventually cease
98
Token Economies
Behavior Therapy:
"Tokens" are given to desirable behaviors that are taken away for various undesirable behaviors; These tokens can later be exchanged by the client for a wide array of rewards / privileges
99
Premack Principle
Behavior Therapy:
More preferred activity can be used to reinforce a less preferred activity
100
Contingency Management
General name for behavior therapies that attempt to change the client's behavior by altering the consequences of the behavior
101
Insight
Perception of the inner relationships between factors that are essential to solving a problem
102
Cognitive Map
Mental representation of a physical space
103
Biological Constraints
Different species that have different inborn predispositions to learn different things in different ways
104
Preparedness
Innate, in-born tendency to associate certain stimuli with certain consequences
105
Fixed - Action patterns (FAP)
Stereotyped behavior sequence that does not have to be learned by the animal (it is species - typical)
This is an automatic response; even if the stimulus is removed in the middle of the behavioral sequence the animal will continue to perform the action
106
Sign Stimuli
Features of a stimulus that are sufficient to bring about a particular Fixed Action Pattern
107
Releasers
Stimuli that function as signals from one animal to another; particular environmental stimulus that sets off a specific behavior
108
Supernormal Stimulus
Stimulus that is more effective at triggering the Fixed Action Patterns (FAP) than the actual stimulus found in nature
109
Innate Releasing Mechanism (IRM)
Mechanism in the organisms nervous system that serves to connect the stimulus with the right response
110
Reproductive Isolating Mechanism
Prevent animals of one species from attempting to mate with animals of closely related species; Provides a way for species to identify other of it's own species
111
Elaborative Rehearsal
Organizing the material and associating it with information you already have in long term memory
112
Recall
Independently reproducing the information that you have previously been exposed to
113
Recognition
Realizing that a certain stimulus event is one you have seen or heard before
114
Generation - Recognition Model
Recall task taps the same basic process of accessing information in memory as does a recognition task, but a recall task requires an additional step (generating info.)
*Explains why Recognizing is easier than Recalling
115
Stage Theory of Memory
There are several different memory system and each system has a different function; Memories will enter the various systems in a specific order
116
Storage
Retaining Information in memory over time
117
Recency Effect
Words presented at the end of a list are remembered best
118
Primacy Effect
Words presented at the beginning of the list are remembered best
119
Clustering
When asked to recall a list of words, people tend to recall words belonging
120
Semantic Verification Task
Asked to indicate whether or not a simple statement presented is true or false
121
Response Latency
Time it takes the subject to respond
122
Spreading Activation Model
Semantic Memory organized into a map of interconnected concepts; The shorter the distance between 2 words, the closer the words are related in the semantic memory
123
Level (Depth) of Processing Theory
What determines how long you will remember material is not what memory system it gets into (suggesting there is only one memory system) but the way in which you process the material
124
Physical Processing of Information
Visual - focusing on the appearance, size and shape of the information
125
Acoustical Processing of Information
Auditory - focusing on the sound combinations words have
126
Semantic Processing of Information
Focusing on the meaning of the word
127
Paivio's Dual-Code Hypothesis
Information can be stored or encoded in 2 ways: Visually (Concrete info) and Verbally (Abstract info.)
128
Schema
Conceptual frameworks we use to organize our knowledge
129
Decay Theory
Information in long term memory that is not used or rehearsed will eventually be forgotten
130
Inhibition Theory
Forgetting is due to the activities that have taken place between original learning and the later attempted recall
131
Encoding Specificity
Recall will be best if the context at recall approximates the context during the original encoding
132
Zeigarnik Effect
Tendency to remember incomplete tasks better than completed tasks
