Personal investigation 2- stroop test Flashcards
(52 cards)
What is the title of our investigation?
A correlation study involving the stroop test
What is a correlation study?
A correlation study is a relationship between covariables
A scatter diagram is used to present the data
The closer the coefficient is to 0 the weaker the coefficient.
The closer to +1 or -1 the stronger it is
What is the stroop test?
The stroop test can be used to measure a persons attention capacity and skills, processing speed and evaluate executive processing ability
What is the stroop effect?
The delay in reaction time between automatic and controlled processing information, in which the names and the words interfere with the ability to name the colour of ink used to print the words (Tam 2015)
What are the two co variables in the study?
1- Creativity scores on the Kellogg creativity questionnaires out of 116
2- Time taken (sec) to accurately complete the stroop test
What are some cofounding variables in the study?
CV- affect some of the participants
Dyslexia
Visual impairments
Size of the screen
Prior experience
Concentration levels depending on hours of sleep or lessons before
What are some extraneous variables of the study?
EV- a variable that affects all the p’s and there results but isn’t manipulated or measures
Noise levels
Temperature
Lighting of room
What type of hypothesis have we used in our study and why?
Directional
Theirs been previous research done on this
What is our hypothesis?
There will be a decrease in stroop test time in seconds in those who have creativity scores (Kellog) over 50 than those who scored under 50
What is our null hypothesis?
There will be no significant difference in stroop test time in seconds in those who have creativity scores (Kellog) over 50 than those who scored under 50
Methodology- Define a correlation and what it show?
A relationship between co variables
Shows strength and type of relationship (pos or neg) of the variable
Methodology- strengths of correlations?
High ecological validity
Quick and easy
Precise
Can be used when its unethical and impractical to manipulate variables
Methodology- weaknesses of correlations?
Cant have a cause and effect relationship, lack of internal and external validity
Sampling- who makes up the target population?
Members at notre dame
Sampling- who is our sampling frame?
Students and staff at notre dame
Sampling- what sampling method should we use?
Opportunity sampling
Sampling- what is opportunity sampling?
This is the method used when participants are available at the time of research
Sampling- justify why we have used opportunity?
A strength of opportunity sampling, is that they are a great deal easier for the researcher to administer in comparison to other sampling techniques which may be more costly on time and research
Ethics- what do we need to do your investigation?
Ethical issues surrounding your research. Specification clearly states that the BPS code of Ethics and Conduct (2009) must be adhered to in implementation of the investigations
Ethics- privacy in the research?
-Not share scores with participants
-If students have got SEND issues, don’t tell participant, only people that have done research in groups
Ethics- Confidentiality in the research?
Giving participants different codes for their names
-Getting rid of tests score sheets, keeping result but in a safe space
Ethics- Deception in the research?
Giving a brief and a debrief
Ethics- Right to withdrawal in the research?
Write this in brief or debrief giving email to tell them to withdrawal
Ethics- Informed consent in the research?
Working with children- have to get consent from a responsible adult (not true consent)
-16+ can consent themselves
