First proposed by American psychologist Kimberly S. Young in 1996, the theory is one of the pioneering theories in the field of digital psychology. She focuses on how people can become overly dependent on technology, especially the internet and social media. This theory argues that technology provides stimulating experiences that enhance the production of brain chemicals such as dopamine, which makes people want to return to these technologies more often. Given the possibility of access to information and instant interaction, this use can develop into a digital addiction. Recent research focuses on behavioral effects that can occur, such as distraction, inability to disconnect from digital devices, and decreased social skills in the real world. This theory emphasizes the importance of respecting reasonable boundaries when using digital technologies and encourages a balance between digital and real life to support mental health.
