9.3.2 Practical Issues In The Design And Implementation Of Research Flashcards
What is the IV?
The one thing that you change.
What is the DV?
The change that happens as a result of the IV.
What is operationalising variables?
How you will define and measure a specific variable.
What are participant variables?
Related to individual characteristics of each ppt that may impact how they respond. E.g. mood, intelligence
What are situational variables?
Factors in environment that can unintentionally affect the results of a study. E.g. temperature, noise.
What is experimenter bias?
Where the experimenter influences the results in order to portray a particular outcome.
How can demand characteristics create bias?
Clues given to the ppt about tehe point of the experiment.
How can interpretation of data create bias?
The results may be interpreted wrongly; for example if subjective data, such as qualitative, is gathered.
How can inter-rater reliability create bias?
Can’t decide what the results are, so can’t make a conclusion
How can triangulation create bias?
Information and details can be lost as it is passed from one person to another.
How can social desirability create bias?
Ppts lie, which ruins the results so they look better to others.
How can interviewer bias create bias?
The results are bended to fit what the interviewer expected to see.
How can experimenter bias create bias?
Can’t reach a conclusion.
Sherif generalisability
Low because small sample; 24 boys, all aged 11.
Sherif validity
Low ecological validity, ppts spent time away from home with a group of boys they have never met before, which is unnatural and may have created unnatural results.
Sherif subjectivity/ objectivity
A lot of the results was observation, which is subective.
Raine Generalisability
High generalisablility, a variety of ppts were used; mix of men and women, mix of mental health disorders and non mental health disorders.
Raine validity
A CPT was used which could have been considered artificial; the ppts were completing an unnatural task. low ecological validity.
