Psych Exam revison Flashcards
What is a between-subjects design in experimental research?
A design where different participants are assigned to different conditions, so each participant experiences only one condition of the experiment.
What is a within-subjects design in experimental research?
A design where the same participants are exposed to all conditions of the experiment, allowing for direct comparisons of each condition.
What are the advantages of a within-subjects design?
It requires fewer participants and controls for individual differences between groups.
What are the disadvantages of a within-subjects design?
Fatigue and order effects
What is a mixed design in experimental research?
A design that combines both between-subjects and within-subjects elements, allowing some variables to be tested across different groups and others within the same group.
What are common sampling procedures in psychology research? (3)
Random sampling, stratified sampling, and convenience sampling.
How does random sampling differ from convenience sampling?
Random sampling ensures every member of the population has an equal chance of being selected, while convenience sampling selects participants based on availability, not randomness.
GUSTATORY SYNAESTHESIA
Experiencing sensations of taste when they perceive certain words
WWhat is the difference between a sample and the population in an experiment?
The population is the entire group a researcher is interested in studying, while the sample is the subset of that population used in the actual experiment.
Define independent variable (IV) and dependent variable (DV).
The IV is the variable manipulated by the experimenter, and the DV is the variable measured to determine the effect of the IV.
What is an extraneous variable in an experiment?
Any variable other than the IV that might influence the DV if not controlled. Identified at the begining
What are confounding variables?
Variables that influence both the IV and DV, causing potential false correlations between them, thus “confounding” the results. This is identified at end of the experiment
How can confounding variables be reduced?
Through randomization, use of control groups, and matching participants across conditions to account for individual differences.
What does it mean to operationalize variables in an experiment?
It means defining the variables in measurable terms so they can be tested. For example, operationalizing “stress” might involve measuring heart rate or cortisol levels.
What is informed consent in psychological research?
The process by which participants are informed about the nature of the study, potential risks, and benefits, and voluntarily agree to participate.
What are withdrawal rights in psychology experiments?
The right of participants to leave the study at any time without any negative consequences or explanation required.
What is confidentiality in psychology research?
Ensuring that all personal information and data collected during the study is kept private and not shared without consent.
When is the use of deception allowed in psychological research?
Deception is only allowed when no other alternative exists to achieve the study’s aims and when participants are fully debriefed afterward.
What is debriefing in psychological research?
Explaining the true nature and purpose of the study to participants after it has been completed, especially if deception was used.
Define voluntary participation.
Participants must choose to participate in research freely, without coercion or undue influence.
What does the concept of justice entail in psychological research?
Ensuring fair treatment and distribution of risks and benefits among participants.
How does integrity apply to psychology research?
Integrity involves conducting research in an honest, ethical, and accurate manner, without falsifying or misrepresenting data.
What does non-maleficence mean in the context of psychological research?
Researchers must ensure that no harm comes to participants, minimizing risks wherever possible.
What is beneficence in psychological research?
The obligation to maximize benefits and minimize harm to participants during the study.
