Activity Experimental Method: investigating short term memory
Research suggests that Short Term Memory (STM) cannot hold very much information.
You are going to design an experiment to see whether the time of the day effects the capacity of STM or not.
Generate a (directional) hypothesis for this study.
Justify the direction of your hypothesis.
Identify the IV and DV in this experiment.
Identify any FIVE significant CONTROL variables and how you would control.
Also identify any TWO EXTRANEOUS VARAIBLES
Devise a brief and suitable set of instructions that will be read or given to participants in order to:
· gain their consent to take part
· enable them to carry out the task appropriately.
Develop an appropriate task for measuring the capacity of STM; for e.g. memorizing number sets) or a word list..
Think carefully about the materials you will use and explain why these factors need to be controlled, e.g.:
· length of words
· type of words
· number of words
· word presentation
Decide upon and justify your choice of participants for the two conditions (the control and experimental groups).
Briefly explain procedure of your experiment step-wise
Before you collect your data, identify and address any TWO ethical issues which may arise from the study you have designed. For example, consider how participants will be debriefed afterwards.
