Examining the relationship between gender and short term memory
Materials required for the experiment:
- 20 male participants aged between 18 to 30 years old
- 20 female participants aged between 18 to 30 years old
- 25 objects – i.e. apple, ball, clock, chair, umbrella, banana, cup, radio, etc.
- 1 stop watch
- 40 pieces of paper and pencils
- 1 classroom with tables and chairs
- 1 curtain
- 1 assistant
1. The independent variable in this experiment is the gender of the participants. The dependent variable is the ability of male and female participants to recall the objects they saw, which is determined by asking them to write down what they saw in a piece of paper. The constants (control variables) are the number and type of objects, the time given for the participants to look at the objects, and the time given to write down the list of objects.
2. Arrange the 25 objects in front of the classroom. Fix a curtain to hide the objects from the audience’s view before and after the start of the experiment.
3. Bring the participants into the classroom. They can either be tested together as one big group or be separated into smaller groups. Draw the curtains open and instruct the participants to look at the 25 objects and remember them for two minutes. The assistant will observe the time with the stopwatch.
4. After two minutes, draw the curtains close and give each participant a piece of paper and pencil. Instruct them to write their names, gender and age on the paper. Give the participants five minutes to recall and list down the objects that they had observed earlier.
5. Collect the papers back after five minutes. Check and tally their results, and recorded it in the table given below.
