Methodology I
The Variable psychologist chooses to measure
Dependent Variable
When a participant only takes part in one level of the IV
Independent measures design
"Any difference in the number of words spelt correctly of females compared to males will be due to chance."
Is an example of this.
A null-hypothesis
Information about the experiment has been given to the participant and has been understood by them.
Informed consent
Psychologists should at least consider using video footage or computer simulations. Pertains to this Ethical guideline.
Replacement
These represent different conditions being compared / tested in a study
Independent Variables
When the participant takes part in all of the levels of the IV
Repeated measures design
This is written before a study is run and it serves to relay the purpose of a study.
Aim
Participants must leave any study in the same physical and psychological state as they entered.
Protection of physical/psychological harm.
Psychologists should always use the smallest number of animals that still accomplishes the research aims and goals. This pertains to which Ethical Guideline
Numbers
In this type pf experiment, the IV effect is measured outside of a laboratory, in a more natural environment.
Field experiment
A strength for this type of study is that one can get very detailed information about individuals or small, close-knit groups
"Females will be able to spell more words correctly compared to males."
Is an example of this.
One-tailed or directional hypothesis
"There is a difference between withholding some of the details of the hypotheses under test and deliberately falsely informing the participants of the purpose of the research."
This phrase refers to which Ethical Measure?
Deception
Living conditions should take into account the social behavior of the species. Pertains to which ethical guideline?
Housing
This method is used when researchers use a pre-existing or naturally occurring IV.
Natural Experiment
These involve certain questions that must be asked of participants, but the person conducting it can ask them in a different order or ask follow up questions
Semi-structured interviews
"There will be a difference in the number of words spelt correctly by females compared to males."
Is an example of this
two-tailed/ non-directional hypothesis
Explain what occurred in study and the true nature of the study. Happens immediately after study has finished.
Debrief
The psychologists should employ the species which isn likely to suffer least while still attaining the scientific objective. Pertains to which Ethical Guideline?
Species and Strain
Traits and behaviors that participants bring to the study that may affect the DV
Participant variables
Weakness of interviews
Participant variables can account for a weakness of this type of experimental design
Independent Measures
Subjects should know that they can withdraw themselves and/or any data from the study at any time and how to go about this.
Right To Withdraw
Participants data cannot be disclosed. What guideline does this pertain to?
Privacy/Confidentiality
