25
Illusion of Control
People's belief that they can influence events, even when they have no control over what will happen.
26
Scientific Attitude
Curiosity, skepticism, and humility.
27
Scientific Approach Requires
Communalism: Willingness to share finding and be open to hearing others ideas and beliefs.
Disinterestedness: (not interested in the outcome of the result).
28
Descriptive (Naturalistic)
External Validity: The extent to which we can generalize our findings to the real world
Internal Validity: The extent to which we can draw cause-and-effect inferences.
29
Correlational Designs + Example
Assess a relationship between variables without the researcher controlling or manipulating them.
Example: If there are multiple pizza trucks in the area and each has a different jingle, we would memorize it all and relate the jingle to its pizza truck. This particular example shows a relationship between two variables (jingle) and (distance of the truck).
30
Illusory Correlation
Perception of a statistical association where none exists.
Example: A soccer player may put tape around his socks before a game. They score a goal and attribute it to the fact that they are wearing tape. The connection between the two variables is an illusion.
31
Correlational-Causation Fallacy

37
Three Experimental Concerns
Confounds: Any difference between the experimental and control groups not manipulated in the independent variable, but may account for the observed changes in the dependent variable.
Placebo Effect: Improvement resulting from the expectation of improvement.
Nocebo Effect: Harm from the expectation of harm.
38
Evaluating Measures
Reliability- consistency of measurement

42
Challenges in cross-cultural research
Equivalence
Linguistics Equivalence: The quality of two sets of words spoken or written in different languages but which have the same meaning.
Measurement Equivalence: A statistical property of measurement that indicates that the same construct is being measured across some specified groups.
Response Bias
Socially Desirable Responding: The tendency of respondents to reply in a manner that will be viewed favorably by others.
Acquiescence Bias: The tendency for survey respondents to agree with research statements, without the action being a true reflection of their own position or the question itself.
43
Descriptive Statistics

Dispersion
Range: Difference between the highest and lowest scores
Standard Deviation: Based no how far each data point is from the mean
44

Significant Result: Results the real world rather than chance
Not significant: Results reflect chance
Practical Significance: The extent to which a study result has meaningful applications in real-world settings.
45

48
Habituation
A decrease in behavior after repeated exposure.
49
Sensitization
An increase in behavior after repeated exposure.
50
Associative Learning
The process through which organisms acquire information about relationships between events or entities in their environment.
Application: If someone puts their hand on a hot stove and hurts themselves, they may learn to associate hot stoves with pain, and have therefore been conditioned to not put their hand on a hot stove and hurt themselves.
51
Classical Conditioning
Definition: Learning through association
Application: [Child @ doctor's office]
Before Conditioning: Unconditioned Stimulus [shots] produces Unconditioned Response
[cries]
Before Conditioning: Neutral Stimulus [healthcare worker] does not produce a response.
During Conditioning: Neutral Stimulus [healthcare worker] + Unconditioned Stimulus [shots] produces Unconditioned Response [crying]
After Conditioning: Conditioned Stimulus [healthcare worker] Produces Conditioned Response [crying]
52
Conditioned Emotional Response
The emotional response that has become classically conditioned to a learned stimulus.
Application: [Child @ doctor's office]
Before Conditioning: Unconditioned Stimulus [shots] produces Unconditioned Response
[cries]
Before Conditioning: Neutral Stimulus [healthcare worker] does not produce a response.
During Conditioning: Neutral Stimulus [healthcare worker] + Unconditioned Stimulus [shots] produces Unconditioned Response [crying]
After Conditioning: Conditioned Stimulus [healthcare worker] Produces Conditioned Response [crying]
53
Generalization Stimulus
Definition: An organism responds to a stimulus in the same way that it responds to a similar stimulus.
54
Discrimination
Definition: Ability to perceive and respond to differences among stimuli.
Application: [wine tasting]. You perceive differences in the wine and respond to the differences by purchasing one wine over the other.
55
Conditioned Taste Aversion
Nausea or aversive response to a particular taste because that taste was followed by a nausea reaction.
56
Acquisition
The learning phase during which a CR is established.
57
Extinction
Definition: Gradual decrease and elimination of the CR when the CS is presented repeatedly without the US.
Application: In the (pavlov dog experiment). The dog is conditioned to associate the bell with food coming. When the (neutral stimulus: Bell) is presented without the (UCS: Food), the dog will stop associating the bell with (food coming), and this will eliminate both the conditioned stimulus and response.
58
Spontaneous Recovery
Sudden reemergence of the CR after the passage of time.
59
Operant Conditioning
A type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher
60
Operant Conditioning Chamber (Skinner)
A Skinner Box contains a bar or key that an animal can manipulate to obtain a food or water reinforcer; attached devices record the animal's rate of bar pressing or key pecking.
61
Continuous Reinforcement Schedule
Reinforcing the desired response every time it occurs.
62
Partial Reinforcement
Term: Reinforcing a response only part of the time.
Example: Pigeon learned to peck a key to obtain food. Phase out food delivery until it occurs rarely, then the pigeon may peck 150,000 times without a reward.
Administration by:
Ratio Schedule: Number of responses
Interval Schedule: Amount of time
**Slower learning but resistant to extinction.
63
Fixed Interval
Definition: Reinforce the first response after a fixed time period. Animals on this type of schedule tend to respond more frequently as the anticipated time for reward draws near.
Application: People check more frequently for the mail as the delivery time approaches.
64
Variable Interval
Definition: Reinforce the first response after varying time intervals.
Application: At unpredictable times, a food pellet rewarded Skinner's pigeons for persistence in pecking a key.
65
Reinforcement after a fixed quantity of responses regardless of time.
Definition: Fixed Ratio Schedule
Application: A person works a summer job and they get paid for every 100 envelopes you stuffed.
Post Reinforcement Pause (Associated): Produce high rates of responding and that decline immediately after the reinforcer is received.
66
Variable Ratio Schedule
Definition: Reinforcement at the unpredictable quantity of responses regardless of time.
Application: The one-armed bandit which is a slot machine. You must pull the arm an unspecified number of times before you are reinforced with a jackpot. Sometimes you can put in a few quarters, pull the arm once, and win a big jackpot. Sometimes you pull and pull but you just never win.
Variable-ratio schedules: produce high rates of responding because reinforcers increase as the number of responses increases.
67
Thorndike's Law of Effect
Responses that lead to satisfying consequences are more likely to be repeated
Application: If you started to follow a new meal plan, and as a result, you started to feel more energized and creative. You are more likely to stick with this meal plan for a while. If the meal plan did not help you make improvements in your life, then you are likely to stop the plan.
68
Higher Order Conditioning
A procedure in which the conditioned stimulus in one conditioning experience is paired with a new neutral stimulus, creating a second (often weaker) conditioned stimulus. For example, an animal that has learned that a tone predicts food might then learn that light predicts the tone and begin responding to the light alone. (Also called second-order conditioning.)
69
Reinforcer
Definition: Encourage behavior
Application:
Positive: (+) Pleasant Stimulus
Example: Give a child a treat when he or she is polite to a stranger.
Negative: (-) Unpleasant Stimulus
Example: Studying for an exam to avoid getting poor grades.
70
Punisher
Definition: Weakens a response
Application:
Positive: + Stimulus
Example: Spank child for bad behavior
Negative: - Stimulus
Example: Taking away drivers license

Describe brain plasticity (4 different ways)
Before birth and until maturation is complete:
Brain changes in response to experience.
During learning (long-term potentiation):
Pathway activated there are changes within the cell to make it so that the first neuron can cause a change in the second neuron more easily.
Stem Cells
Neurogenesis: Most of the neurons we are born with:
Sleeping: Allows for the growth of new neurons
Exercise: Causes inflammation and allows for the growth of new neurons.
86

GABA: A major inhibitory neurotransmitter.
Glutamte: A major excitatory neurotransmitter; involved in memory.
Endorphins: Neurotransmitter that influence the perception of pain or pleasure
87
Be able to describe the process of interneuron communication.
A neuron that conveys impulses from one neuron to another.
When an action potential reaches knob-like terminals at an axon's end, it triggers the release of (neurotransmitters).
Neurotransmitter molecules cross the synaptic gap and bind to receptor sites on receiving neuron either exciting or inhibiting the receiving neuron's readiness to fire.

89
Apoptosis
Programmed cell death
90
Neural Impulses Process (Long)
The (resting) tells about what happened when a neuron is at rest. The (resting) potential is at -70 mV.
Threshold: The graded potential is when the voltage changes based on the sodium and the potassium in the neuron. The (graded) potential goes from (-69 mV) to (-56 mV). This is when the sodium and potassium is changing here and this happens in the dendrites and the soma. It's also called depolarization.
The (action potential) occurs on the (axon). The action potential starts at the threshold. When it goes from (-54 mV) or less: it's all action potential (as it's going from -54 mV or less it is traveling down the axon).
Repolarization: Brings the cell back to resting potential, where the sodium (+) goes back out to the exterior, and it gets more negative inside again.
Refractory Period A neuron is resistant to a second action potential during refractory periods. The body and/or brain are still busy responding to a first stimulus.
Resting State: (-70 mV)
