The Impact of Shallow Reading in Social Media

Study Overview
=================
Brief Summary
-----------------
Social media is pervasively used in our life. There is a research hypothesis that the information in social media is shallow and the long-term use of it will cause readers' addiction, insomnia, and inability to pay attention, thus reducing the efficiency of learning and working. However, there is no systematic study on the relationship between shallow reading in social media and attention, addiction, sleep quality, and other mental health. Therefore, the investigators intend to explore the effect of shallow reading in social media on mental health based on about 300 healthy subjects by conducting questionnaire, cognitive scale assessment, multi-mode MRI scanning and EEG monitoring. A cross-sectional study will be combined with a longitudinal study to explore the clinical characteristics its relationship to brain function.

Detailed Description
-----------------
With the development of social media such as twitter, Facebook and Microblog, shallow reading has gradually become the main way for people to obtain external information and relax. Shallow reading is characterized by incomplete and intermittent reading patterns, and readers often dip into it without thinking. There is a research hypothesis that the information in social media is shallow and the long-term use of it will cause readers' addiction, insomnia, and inability to pay attention, thus reducing the efficiency of learning and working. Some researchers even concern that shallow reading is destroying human beings' suspicion spirit, thinking ability and rational thinking which are based on writing and print culture. However, there is no systematic study on the relationship between shallow reading and attention or other mental health, not to mention its fMRI and EEG characteristics. Therefore, the investigators intend to explore the effect of shallow reading in social media on mental health based on about 300 healthy subjects by conducting questionnaire, cognitive scale assessment, multi-mode MRI scanning and EEG monitoring. A cross-sectional study will be combined with a longitudinal study to better understand both the short-term and long-term effect of shallow reading habit to the mental health and imaging characteristics. The collected indexes will be analyzed to explore the clinical characteristics of people with the habit of shallow reading, and its relationship to mental health, brain imaging characteristics will finally be clarified.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Dynamic change of sustained attention from baseline state to after 2 hours of social media use | Continuous performance test (CPT) will be used to assess the difference of sustained attention before and after social media use. minimum: 0 maximum values: 1 Higher scores mean a better outcome. | Baseline state and after 2 hours | 
| Dynamic change of selective attention from baseline state to after 2 hours of social media use | Stroop color word test (SCWT) will be used to assess the difference of selective attention before and after social media use. minimum: 0 maximum values: 1 Higher scores mean a better outcome. | Baseline state and after 2 hours | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Cerebral blood flow changes from baseline state to after 2 hours of social media use | Artery spin labeling (ASL) in MRI will be used to assess the difference of cerebral blood flow before and after social media use. | Baseline state and after 2 hours | 
| Brain functional connectivity changes from baseline state to after 2 hours of social media use | Blood oxygen level dependent (BOLD) in MRI will be used to assess the difference of functional connectivity before and after social media use. | Baseline state and after 2 hours |
