Screen Time and Sleep.
ANSWER
Title: The Impact of Screen Time on Sleep Quality
Hypothesis: We hypothesize that increased screen time before bedtime is negatively correlated with sleep quality. Specifically, we predict that individuals who spend more time on electronic devices in the hour before bedtime will experience poorer sleep quality compared to those who limit their screen time during this period.
Independent and Dependent Variables:
- Independent Variable: Screen time before bedtime (measured in minutes).
- Dependent Variable: Sleep quality, assessed using a standardized sleep quality questionnaire.
Subjects/Participants: Our study will involve college students living in the same dormitory. We will recruit 100 participants, both males and females, who will be randomly selected from the dormitory population.
Experimental and Control Group Conditions: Participants will be divided into two groups:
- Experimental Group: This group will be instructed to limit screen time to no more than 15 minutes in the hour before bedtime for a period of two weeks. They will be provided with educational materials on the potential negative effects of excessive screen time on sleep.
- Control Group: This group will maintain their usual screen time habits before bedtime for the same two-week period. No specific instructions regarding screen time will be given to this group.
Assignment to Groups: Participants will be randomly assigned to either the experimental or control group to ensure that the groups are comparable in terms of age, gender, and baseline sleep quality.
Experimental Procedure:
- Pre-Study Assessment: Before the experiment begins, all participants will complete a baseline sleep quality questionnaire to measure their initial sleep quality.
- Two-Week Experiment: Participants in the experimental group will follow the screen time restrictions, while those in the control group will continue their regular screen time habits. Both groups will maintain their usual sleep routines.
- Post-Study Assessment: At the end of the two-week period, all participants will complete the same sleep quality questionnaire used in the pre-study assessment.
Possible Results:
- If the experimental group shows a significant improvement in sleep quality compared to the control group, it would support our hypothesis that increased screen time before bedtime negatively affects sleep quality.
- If there is no significant difference in sleep quality between the two groups, it could indicate that screen time before bedtime may not be a primary factor influencing sleep quality.
- In the event that the experimental group experiences worse sleep quality, it might suggest that the abrupt reduction in screen time before bedtime had unintended negative consequences on sleep.
Conclusions: Based on the results of our experiment, we can draw conclusions about the relationship between screen time before bedtime and sleep quality among college students. These findings may have practical implications for promoting better sleep habits and overall well-being among individuals who are frequently exposed to electronic devices in the evening. Moreover, this study contributes to the growing body of research on the impact of technology on sleep patterns, aligning with recent academic discussions and literature on the topic.
QUESTION
Description
Researchers often use a method called an experiment in order to study the causes of human and animal behavior. Design such an experiment based on a change in behavior you have observed in yourself or your roommates this past semester (e.g., eating or sleeping habits, exercise regime, game playing, etc.). Select a behavior that you are particularly interested in studying, and then design the experiment to investigate a possible cause of that behavior. Address the following questions.
- What is the hypothesis you will test in your experiment?
- What are the independent and dependent variables?
- Who will be the subjects or participants in your study?
- What are the experimental and control group conditions? Here, you may assume that you have the resources necessary to conduct your experiment and that you can control, or manipulate, the environment of your subjects as necessary. For example, suppose your hypothesis is as follows: Higher levels of stress from a heavy course workload increase eating activity. Assume that you have the ability to control the workload, etc., of your subjects.
- How will you assign your subjects to groups?
- What are the possible results of your study, and what might these results indicate about your hypothesis?
In a multi-paragraph essay, describe your experiment and explain how you will conduct this experiment to test your hypothesis. Be sure to propose your hypothesis, and then describe the independent and dependent variables, the experimental and control conditions, the subject or participant groups, and the conclusions you can draw based on the results of your experiment. Include information from class materials and readings to support your discussion.
