A psychologist is interested in whether working memory is influenced by sleep loss. The psychologist administers a measure of working memory to a group of subjects at 8 A.M. on Day One of the study and then again at 8 A.M. on Day Two of the study, after keeping the subjects awake the entire night. Does sleep loss affect working memory
The Psychologist is applying a dependent sample test, this involves comparing the same individuals in a group at different time points, or under two different conditions.
In the experiment of determining if sleep loss affects working memory, when the subjects were allowed good sleep, they will be more relaxed and their memory will work optimally compared to when they were denied sleep.
