Key Study:
My investigation is going to be based on an experiment done by Tulving and Pearlstone. There study was based on availability and accessibility using cues to aid recollection. Their aim was to investigate cues and recall and to collect results so that the hypothesis could be confidentially accepted or rejected. They read lists of 12, 24 or 48 words. One group of participants had the category headings in front of them and the other group a blank piece of paper. Category headings had an obvious effect on recall. The cues made the words more accessible.
Hypothesis
Categorised headings will have a significantly improve the recall of a list of words.
Null Hypothesis
Categorised headings will have no effect on the recall of a list of words
Directional Hypothesis
Categorised Headings will significantly improve recall on a list of words.
The Independent Variable will be using category headings and not using category headings. The dependant variable will be measuring the amount of words that are remembered.
If the confounding variables are not controlled then it could falsify the results, consequently the conclusions drawn would be untrue.
Method
Design
I will use a field experiment. I will use repeated measures design because of the confounding variable, being the subject variables, of one group being brighter tan the other. Another participant variable that could affect the results are demand characteristics - the participants could try to guess the words. There is not a lot I can do to prevent this from happening, but I can try to make the experiment as standardised as possible and make clear instructions.
Participants
The sample will be 2 groups of 20 year 12 and 13 at Dallam School. Gender will not be a relevant factor. My target population will be 16 – 18 year olds in South Lakeland. I will use opportunity sampling because it is the most economic one to do.
Apparatus and Materials
The following will be needed to allow this experiment to take place.
For the willing participants
20x paper with the category headings
20x blank pieces of paper
For the researcher to read to the participants
1x list of words with the category headings
1x list of words without the category headings
1x stop clock to allow 3 mins for recall
I constructed the list of words after a group discussion.
Procedure
The participants will be fully briefed, debriefed and will be given standardised instructions. Briefing and debriefing are for the interest of the participants as so are the standardised instructions to give the participants full instructions about what to do in the experiment. Not only are the briefing, debriefing and the standardised instructions (see appendix) part of the BPS guidelines but allow other researchers to recreate your study.
