Scientific processes Flashcards
What is ethical guidlines
Designed to protect the well being and dignitity of research P’s
for example consent and deception ect
What are the guidlines pyschologist has to follow
- Consent
- Deception
- Debriefing
- Withdrawl from the investigation
- confidentiality
- protection of P’s
- observational research
Dilema for researcher
What are the dilema of deception and informed consent
- If the P’s are not deceived about the true aims of the study they will show the effects of demand characteristics
- The dilema for researcher is to design research that portrays human behaviour while at the same time making sure they arent breaching ethical guidlines
What is a cost benefit analysis and con of this
This is where researcher try to balance out the potential benefits against potential cost but it is almost impossible to calculate the cost and benefits as researcher can’t always predict
What is presumptive consent
Presumptive consent is where the “P’s” who are going to be studied are informed of the deatils of the study and asked “if they were to participate” would they consider the research acceptable
What is prior general consent and give an example
- This involve asking questions of people who have volunteered to participate before they are selected
- For example “Would you mind being involved in a study where you are deceived?”
what are the ethical issues of Field experiments
A ethical of field experiments is that it is hard to obtain informed consent also it can be hard to de breif the P’s
Confidentiallity, social variables
What are the ethical issues of a natural experiment
Confidentiallity can be a problem as the sample studied might be identifiable. Naturally occuring social variables are studied for example income and race and can raise ethical issues
What is a research aim
A research aim is a general statmement of the purpose of the study and make a clear point what they intend to investigate
What is a hypothesis
A hypothesis is a guess that the researcher belevies to be true about the target population
What is null hypothesis
This is when there is no difference and no correlation, the IV does not affect the DV
One tailed
What is a directional hypothesis
This is known as a one tailed hypothesis and it predicts the direction the results are going to go, this is used when previous researcher suggest there is a clear predicition
two tailed hypothesis
What is a non directional hypothesis
This is also known as a two tailed hypothesis because even though the researcher expect the IV will effect the DV they are not sure how
What is random sampling
This is when the researcher selects random people from a certain population using a hat method or a computer
Strength and weakness of random sampling
- Strength - True sample avoids bias
- Weakness - Impossible to obtain a 100% random sample
