Question

1.1. Dr. Marshall wants to investigate the effects of stress relief on attention. Specifically, he wants to see how playing with a fidget spinner will affect a person’s ability to detect a tone. In this scenario, Dr. Marshall will have two groups of participants - the experimental group and the control group. All participants in the study will complete the attention task where they press a button as soon as they hear the specific tone, but what would be the difference between what participants have to do in the experimental group compared to those in the control group?

1.2 Dr. Marshall’s fidget spinner experiment doesn’t go as planned, so he wants to run a new study. This time, he wants to see how using a fidget spinner will affect a person’s memory. In this scenario, how might Dr. Marshall operationally define memory?

Explanation / Answer

1. The difference will be that the participants in the experimental group will be provided with the fidget spinner but the participants in the control group will not be provided with the fidget spinner.
2. Memory can be operationally defined as the ability to recall maximum number of items from a list of nonsense syllables.
