(229 cards)
1
Q
Voluntarism
A
Created by William Wunt. Belief that we control what we do and when we do it?
2
Q
Structuralism
A
Created by Edward Tichener. Belief that we need to break down the idea of the conciseness into images and experience. Describe conciseness.
3
Q
Functionalism
A
Created by Wiliam James. Comes from natural selection and comes from Structuralism. Doesn’t want to describe conciseness but instead figure out why. What the function is and we did we develop this way
4
Q
Behaviorism
A
Created (mainly) by John Watson and BF skinner. Was focused on stimulus and what is observable. Believed in the black box theory’s, didn’t matter what happened in the brain, just what the input was and then was the output was.
5
Q
Gestalt psychology
A
Created by Max Wertheimer. Believes` in breaking behavior into components loses meaning. Emphasizes that the whole of anything is greater than its parts
6
Q
Humanism
A
Created by Carl Rogers and Abraham Maslow. Was a direct reaction to Freuds unconciseness mind theory and his primal urge theory. He wanted to focus on the things that happen whne humans do sometime right. Now called positives psych
7
Q
What must all scientific theories be?
A
Something that is going to explain the relationship between two or more variables
Testable: Using the currently availably method
Falsifiable: must be possible (in principle) to make an observation that would show the proposition to be false even if that obsecration has not been made. (Freuds theories were mostly unfalsifiable)
Parsimonious: Focus on finding the simplest accurate explanation for cognitive processes and behaviors

Q
What are the three big Research Categories
A
- Descriptive methods: Often concerned with a single variable of interest
2.Correlational methods: Examine associations between
two or more variables
3.Experimental methods: Examine cause-and-effect
relationships between two or more variables
23
Q
Descriptive method
A
Involves the systemics observations and classification behavior(Not the most reliable)
Includes: Surveys, focus groups, case studies and observation research.
24
Q
What are the 3 types of Observational methods
A
Naturalistic, Participant , and Laboratory
25
Naturalistic observation
Passive observation. Observers do not change or alter ongoing behavior (at least not intentionally). Is done in a public place so people are aware that they could be observed
26
Participant observation
Active observation. The researcher is actively involved in the situation. ( Involves the researcher getting involved deeply into their observation. )
27
Laboratory observation
Systematic observations are made within a laboratory setting, the observer can tailor the environment to what the study is about (rather than in the ‘real world’).
28
Pros of Descriptive research
1.Case studies and observational research can provide important insights and stimulate further research to test specific hypotheses
2. Surveys allow us to gather large amounts of information quickly and easily
3. Focus groups and interviews can provide rich, detailed information that may be lacking from a survey
29
Cons of Descriptive research
1. Can cause Reactivity
2.Observer/experimenter bias, observers are not robots, they are looking for something and may look for what they want to see, you can help this by having 2 people report this so that you can see what alias in their reports
3. Self-report bias, we are not unbiased and we want to appear like a socially desirable group
30
Correlation Methods
Involve examining how variables are related you are MEASURING THESE variables, not manipulating the variables (without manipulating any of the variables)
31
What are the types of possible relationships that can be shown through correlation research.
1. No relationship (0): between the variables
2. Positives relationship (+): Both variables move in the same direction (both are positives or both negative) and can have a high/strong or weak/low degree based on how the close to 1
3. Negative relationship (-): Variables move in the opposites direction (one is positive one is negative) and can have a high/strong or low/weak degree based on how the close to -1
32
What is the big rule in Correlation studies
Correlational studies do not tell us whether one variable causes changes in another variable(correlation=/causation)
33
Why isn't correlation =/= causation?
Directionality problem: Not knowing which of the variables was the cause and which the is effect from a correlational observation .
Third party Variable: Not knowing if there was another unasked factor helped cause the results that the observer cannot accounts for
34
Experimental Methods
Manipulating an independent variable in order to determine its impact on a dependent variable (which we measure) ( Are tightly controlled (typically take place in the laboratory
35
Control group
This is a group that doesn’t get treatment or gets a placebo to see what the baseline effect would be
36
Confounds
a variable that is not your independent variable that is varying systematically along with your independent variable limit our ability to make causal claims
37
Random assignment
Every single person has an equal chance of being assigned to any part of your study. It's a necessary component of an experiment, because this ensures that your different groups are equivalent on average
38
Random sample
Each member of the population you are interested in has an equal chance of being chosen to participate
39
Hawthorne effect
People's tendency to behave differently when they become aware that they are being observed
40
Double Blind Experiment
A double-blind experiment is when both the participants and the experimenters who interact with the participants are unaware of which condition the participant is in
41
Population
The group that you want to be able to generalize your finding to. Every person in this population has a chance of being a part of the sample
42
Sample
The group of individuals from this population who are a part of this study
43
What is a field experiment
Experiments that occur in real-world settings (the “field”) rather than the laboratory. Random assignment is possible but it's harder as the researcher has less control.
44
Quasi-Experiments
Experimental design where random assignment is not possible. Risk of potential confounds limits the claims that a researcher can make.
45
What is W.E.I.R.D
This is the idea that most study are not applicable to all due to them only being down on WEIRD populations. (Western, Educated, Industrial, Rich, Democracies)
46
Reliability
How well the experiment can be repeated and how accurate the experiment is to get the same thing.
47
Interrater Reliability
This is when you don’t want to data from a single observer. You want to have a bunch of independent observers and then to review all of their data and to see what they agree on to get an overall idea of what the experiments
48
Test-retest
This is when you can repeat the test or study that you did before and get the very similar results. You want to have a continuality.
49
Validity
how well the results among the study participants represent true findings among
50
Construct validity
How accurately have the variables been Operationalizations. (Making sure a study is measuring the correct things and making sure that the study is taking into account the external and internal validity )
51
External validity
How well do we think the results from this study would translate into different people and contexts OUTSIDE the study. (Generalizability)
52
Internal validity
How well has the study established a cause and effect relationship between variables (Are there confounds in the experiment?) Causality
53
Descriptive statistics
It helps analyze data to help describe, show or summarize it in a meaningful way
54
Inferential statistics
Allow us to extend conclusions from a sample to a population
55
Reproducibility
That a study can be duplicated in method and/or analysis
56
Replicability
when the entire research process is conducted again to test the same question, wheather or not the results would be the same.
