When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

What is an Experiment?

15.5K
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

Area of Science:

  • Psychology
  • Human-Computer Interaction
  • Digital Well-being

Background:

  • Problematic smartphone use is a growing global concern.
  • Excessive screen time negatively impacts mental health and cognitive function.

Purpose of the Study:

  • To evaluate the efficacy of a multi-strategy intervention designed to reduce problematic smartphone use.
  • To assess the intervention's impact on well-being, cognition, and sleep quality.

Main Methods:

  • Two studies were conducted: Study 1 used a pre-post design, and Study 2 compared the intervention group to a control group.
  • Participants selected from ten strategies (e.g., disabling notifications, greyscale display) for 2-6 weeks.
  • Measures included smartphone use, well-being, cognition, and sleep quality.

Main Results:

  • Study 1 demonstrated significant reductions in problematic smartphone use, screen time, and depressive symptoms.
  • Study 2 showed the intervention group had lower problematic smartphone use, reduced screen time, and improved sleep quality compared to controls.
  • The intervention's positive effects on problematic smartphone use persisted for at least 6 weeks.

Conclusions:

  • A brief, multi-strategy intervention is effective in reducing problematic smartphone use.
  • Combining various nudging strategies is feasible and efficacious for digital well-being.
  • The intervention offers a practical solution for mitigating negative impacts of excessive smartphone use.
