Q

That is a theory?

A

A theory is a systematic way of organising and explaining observations; different schools of thought promote different theories which can lead to new testable predictions

Q

What is a dependent variable?

Study These Flashcards
A

The variable that is measured

25
What is a sample?
The person or things we test the hypothesis on
26
What is a population?
The entire group of people we are interested in studying
27
What is a sample?
A subset of the population selected for the study
28
What is random sampling?
Each member of the population is equally likely to be included in the experiment
29
What is a representative sample
Possesses the important characteristics of the population in the same proportions
30
What is reliability?
Whether the measure produces a consistent result
31
What is validity
Whether it measures what it's supposed to measure
32
What are the three techniques to determine the reliability of a measure?
Test-retest reliability Internal consistency Inter-rater reliability
33
What is the test retest reliability technique?
Whether the test gives similar values if the same participant takes it two or more times
34
What is the internal consistency technique?
Different items that measure the same variable should produce similar answers and be consistent
35
What is the inter rater reliability technique?
Two testers who rate the same person on the same variable should give similar ratings on the participant
36
What it correlational coefficient?
Measures the strength of a relationship between 2 variables.
37
What is a positive correlation?
People with high scores on one variable tend to have higher scores in the other
38
What is a negative correlation?
People with high scores on one variable are likely to have low scores on the other variable
39
What does it mean when there is no correlation?
A high score on one dimension predicts nothing about a persons score on the other dimension
40
What are the basic elements of an experiment?
A hypothesis Manipulation of independent variables (random assignment and holding all other variables constant) Measurement of the dependent variable Eliminating sources of bias/alternative explanations of results Conclusion
41
How does an experimenter hold other variables constant?
With an experimental group, control group or with random assignment
42
What is an experimental group?
Exposed to the experimental conditions
43
What is a control group?
They are not exposed to the experimental condition, but other treated identically to the experimental group
44
What is random assignment?
Where participants are equal ally likely to be in either the control or experimental group
45
What is participant bias?
The tendency for people who know they are participants on a study to behaved in a way other than they normally would. E.g. The Hawthorne effect
46
What is self presentation?
The demand of characteristics and the placebo effect
47
What is the demand of characteristics?
Participants respond in the way they think the experimenter wands them to respond
48
What is the placebo effect?
Participants condition improves because they believe the procedures will help them.
49
What is an experimenter bias?
The tendency of experimenters to let their expectancies alter the way they treat their participants.
50
What is a self-fulfilling prophecy?
A false definition of a situation that evokes behaviour that, in turn, makes the false conception become true
51
What is a single blind study?
A technique to control bias that either the experiment or participant is unaware of the purpose of the study
52
What is a double blind study?
Where both the experimenter and the participant are blind to the purpose of the study
53
What is in the code of ethics in psychological research?
``` Informed consent Maintain participant welfare Voluntary participation Ensure confidentiality Avoid deception Fair and humane treatment of animals Gain appropriate ethics approval ```
54
What is a theoretic framework?
Systematic way of organising and explaining observations | Hypothesis that flows from the theory or form an important question
55
What is a standardised prosecute?
Procedure that is the same for all participants except where variation is introduced to test a hypothesis
56
What is generalizabity?
Sample that is representative of the population. | procedure that is sensible and relevant to circumstances outside the laboratory
57
What is an objective measurement?
Measures that are reliable (that produces consistent results) Measures that are valid ( that assess the dimensions they purport to assess)
58
What is psychological science for the scientist?
Understanding human and animal behaviour, thoughts and feelings
