Research suggests that Short Term Memory (STM) cannot hold very much information.

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.

Tasks

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.

Materials

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

Participants (Sample)

Decide upon and justify your choice of participants for the two conditions (the control and experimental groups).

Procedure

Briefly explain procedure of your experiment step-wise

Ethical issues

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.
