Q

Central tendency

A

a statistic that identifies a single value as representative of the entire distribution of data. The three measures of central tendency in psychology are the mean, the median, and the mode of a sample, where the sample should be representative of the population. Measures of central tendency help you find the middle, or average, of a data set.

Q

Falsifiability in Research

A

Something that is falsifiable can be disproven.
IT IS ABLE TO BE DISPROVEN BUT THAT DOESN’T MEAN THAT IT LITERALLY CAN BE.
If a theory is falsifiable then it is scientific, if not then it is unscientific.

25
Independent Variable
The experimental factor that is manipulated or changed; the variable whose effect is being studied

29
Random Assignment
Randomly placing people in experimental or control groups to minimize differences in the population groups ex: turning people into a number to place them in groups randomly to limit human bias
30
How does random assignment differ from random sampling in the experimentation process?
Random sampling comes first and you make sure that the population is fairly represented. Then, random assignment is when you place those participants in experimental or control groups randomly.
31
Meta-analysis
A procedure that makes things more efficient. It statistically combines the results of many different research studies addressing questions around the same research topic Basically creating a big summary of all the data on one topic
32
Correlation
Relationship between data points that is meant to see how A influences B WHEN DESCRIBING THESE, USE CORRELATIONAL LANGUAGE DO NOT USE THE WORD CAUSE.
33
Clinical Psychology
Studying, assessing, and treating people or small groups with psychological disorders, stress issues and life difficulty. Often longer term therapy than counselors provide and dealing with more severe mental health issues than counselors
34
Biological Approach
Key words: genes, brain, hormones, neurons Emphasis: genetics and biological processes, a focus on body and brain
35
Informed Consent
Ethical principle that research participants have to be told enough to enable them to choose whether they wish to participate Parent / guardian must give permission if under 18yrs old- Informed assent
36
Beneficence
(minimize harm or do no harm) an ethical principle that guides researchers and practitioners to prioritize the well-being of individuals involved in studies or receiving treatments. It is an obligation to act in ways that promote the welfare of others, and emphasizes the responsibility to treat people with compassion and minimize harm as much as possible.
37
Does correlation prove causation?
NO
38
Social Psychology
Study of how we think about, influence and relate to one another
39
Psychodynamic/ Psychoanalytic
Emphasis: Unconscious dynamics, motives, conflicts, and past experiences(especially trauma and parental conflicts) Key Words: Unconscious, unresolved conflicts, defense mechanisms, repression, ego, nature vs nurture

He recognized and established the ground rules for the field of psychology that is now based on research and experimentation and he created the first psychology laboratory.
43
Sport Psychology
Study of performance optimization for athletes, musicians, actors, police and military officers, etc.
44
Single-Blind Study
When the subjects/patients do not know all of the information about the study while it is occuring, especially whether they belong to the experimental or control group. Researchers are aware of these things.
45

52
Counseling Psychology
Assists people with problems in living and in acheiving greater well-being, often related to school, work-life balance, stress issues or marriage
53
Hindsight Bias
A type of confirmation bias; The tendency to believe, AFTER watching or learning an outcome that you knew the outcome all along
54
Skewed Distribution
Shows that data is not consistent and lacks any symmetry around the average value
55
Positive Correlation
two like quantity statements (“more-more” and “less-less”) Line is slanted up Ex: The more I study, the higher my test grade is
56
Confounding Variable
A factor other than the independent variable that might produce an effect in an experiment This could include the temperature of the room, color of paint on walls, time of day/year…
57
Generalizability
results of your study can be applied to different types of people
58
Standard Deviation in Research
A computed measure of how much scores vary around the mean. It's a measure of variability in a set of scores or values, and how far they deviate from the mean A small SD indicates that data points are close to the mean, while a large SD indicates that they are spread out across many different values. A SMALL SD IS BETTER BECAUSE IT MEANS YOUR DATA IS CONSISTENT.
59
Correlation Coefficient(r)
Statistical measure of a relationship on a scale of -1 to 1. They reveal how well thing predicts the other If the r value is between -.5 and .5 then it is a weak correlation. If it is really close to 0 then it is a negligible correlation. If it is between -.5 and -1 and .5 and 1 then it is a strong correlation.
60
Socio-cultural approach
Key words: society, culture norms, social interaction, gender, race, ethnicity, socioeconomic Emphasis: Social interaction and the cultural influence on behavior and mental processes
61
Sampling bias
A flawed sampling process that produces an unrepresentative sample of a population ex: the research is about minorities and the sample is mainly white people
62
What would a small SD look like? A large SD?
Small: Like a peak because they are clustered together Large: Like a hill because they are spread out
63
Psychological Approach
Learned fears and other learned expectations Emotional responses Mental processes and perceptual interpretations
64
Directionality Problem
A limitation of correlational research in psychology that occurs when it's unclear which variable causes changes in another. This can make it difficult to establish casual relationships. For example, if there's a correlation between stress levels and sleep quality, it's not clear if high stress levels cause poor sleep quality, or if poor sleep quality causes increased stress levels.
65
Order of General Research Process
1) Write an Operational Definition for the Dependent Variable and meta-analysis 2) Propose Experiment to IRB for Review for ethics check 3) Random Sample from Population for Generalizability 4) Randomly assign groups 5) Run study and analyze data 6) Then, peer review of your data 7) then replication of study done by someone else and validity 8) then publish
66
What does it mean if your p-value > .05? If it is < .05?
If your p-value is > .05 then your data is likely to be random, but if it is < .05 then your data is unlikely random
67
Descriptive Statistics
Used to measure and describe characteristics of groups. Includes measure of central tendency and measures of variability .
68
Quantitative Research
Measurable and comparable and more fact based Numerical values(ex: rate your strees on a scale from 1-10)
69
Experimenter Bias
The unintentional influence of the experimenter's expectations or preconceived notions on the outcome of a study. Ex: someone is researching something and they think they already know the answer so the questions that they ask their participants are biased or asked poorly.
70
Case Study
Studying one or a few individuals in great depth
71
Educational Psychology
Study of how psychological processes affect and can enhance teaching and learning
72
What’s the difference between a large effect size and a small one? Provide an example to illustrate your point.
Effect size is a quantitative measure of the magnitude of the experimental effect. The larger the effect size, the stronger the relationship between two variables. A large effect size means that a research finding has practical significance, while a small effect size indicates limited practical applications. You can look at the effect size when comparing any two groups to see how substantially different they are. For example, we might want to know the effect of therapy on treating depression. The effect size value will show whether the therapy has had a small, medium, or large effect on depression.
73
DSM-5
Diagnostic classification manual employed by the APA to formally diagnose mental illness with symptoms for each mental illness
74
Psychometrics
Field in psychology that focuses on quantification and measurement of mental attributes, behavior, etc. Ex: SATs, AP tests
75
Naturalistic Observation
Watching and recording behavior of organisms in their natural environment
76
Survey
Asking many people to report their behavior or opinions in less depth
77
Convenience Sample
Any process for selecting a sample of individuals or cases that is neither random nor systematic but rather is governed by chance or ready availability. Convenience sampling involves using respondents who are “convenient” to the researcher. There is no pattern whatsoever in acquiring these respondents—they may be recruited merely asking people who are present in the street, in a public building, or in a workplace, for example.
78
Inferential Statistics
Allows one to generalize – to infer from sample data the probability of something being true of a population For example, based on the data collected from 10 psych students that say they love writing, you infer that all/most psych students love writing.
79
Confounding variable vs third variable problem
Confounding variable is with experiments. Third variable is with correlations.
80
Negative Correlation
two unlike quantity statements (“more-less”) Line is slanted downward "negative slope" Ex: The more I study, the less nervous I am about the test
81
Personality Psychology
Study of an individual’s characteristic pattern of thinking, feeling and acting
82
Self-Report Bias
A measurement error that arises when researchers rely on asking people to describe their thoughts, feelings, or behaviors rather than measuring these directly and objectively in a more experimental way This is typically a problem because people are not self aware or they don't want to get canceled.
83
Types of study that is "paired" with qualitative research
Case studies, naturalistic observation, and interviews
84
85
Confidentiality
An ethical principle that requires experimenters to protect the privacy and personal information of research participants (name, address, face, email, medical information)
86
P-value(probability value)
A number that describes how likely it is that your data occurred by random chance. The level of statistical significance is expressed as a p-value between 0 to 1. If it is closer to 0 then it is def not random, closer to 1 is def random.
87
Mode
The most frequently occuring number
88
Negative Skewed Distribution Where do the mode, median, and mean go?
The skew shifts right in graph Mode is at the top of the peak, median is in the middle of the graph, and mean is towards the botom of the graph
89

Sigmund Freud
90
What is required for a psychological experiment?
Precise operational definitions
91
