The concept encompasses how people use digital devices such as smartphones, computers, and other smart devices. Digital behavior includes activities such as browsing the web, interacting on social media, making online purchases, and sharing personal data. The impact of these behaviors on people’s psychological well-being can be both positive and negative, such as social anxiety caused by social media or a sense of accomplishment from constant interaction with technology. Understanding these behaviors helps researchers and developers improve human-technology interactions and fosters psychological research related to the digital transformations taking place in society.
