Sherry Turkle advanced new theories on the role of media in shaping identity. Her research explores how technology influences personal relationships, communication, and self-perception. In her critical works, including "Alone Together," Turkle argues that digital interactions often replace face-to-face communication, impacting how individuals connect and understand themselves. By analyzing the complex relationship between technology and the self, she raises important questions about authenticity, community, and the evolving nature of human connections in a digital age.
