Lab report
Part B: Memory: The Magical Number 7±2 In this experiment, you will test the magical number of 7±2 for the capacity of the working memory (Miller, 1956). This theory indicates that the number of chunks an average human can hold in working memory is 7 ± 2. Some researchers argued that the number is more likely to be 4 or 5. We will use pictures with colors to test how many objects can be actively held in working memory.
- Attach the scatter plot in your report.
y-axis = number of colors are correct
x-axis= totat number of questions
- Do the results of the scatter plot support the magical number 7? Based on your own data, what is the proper number for the capacity of the memory?
- Were there any outliers in your data? If yes, explain what may have led to these outliers and how they affected the results.
- Describe any shortcomings or limitations of the experimental design. What improvements would you make to the methods?
