Scientists Introduce New Internet Addiction Spectrum

Problematic online usage and Internet addiction lack a refined classification. Using 796 questionnaires, Stangl et al. are the first to reveal a continuum ranging from casual users (i.e. older users) to addicts (i.e. digital natives) acknowledging five different severity levels of problematic online usage to Internet addiction.

Researchers from the University of Surrey and elsewhere have found that young people (24 years and youger) spend an average of six hours a day online; older people spend 4.6 hours online. Problematic online usage and Internet addiction lack a refined classification. Using 796 questionnaires, Stangl et al. are the first to reveal a continuum ranging from casual users (i.e. older users) to addicts (i.e. digital natives) acknowledging five different...

Left: a fully assembled quantum system at Google Quantum AI; prominently displayed is the dilution refrigerator in which the computations occur, the quantum processor and quantum-limited amplifiers installed at the bottom stage of the refrigerator, various cables connecting bottom to top, and control electronics of quantum computer in the back. Right: two generations of Sycamore processors fabricated by Google Quantum AI; each processor features two chips that are bonded together: a chip containing the quantum bits (qubits), and a chip containing the wiring between the qubits and the outside world; the latest generation of the Sycamore processor on the right is notably larger than previous generations, but also has several modifications to the qubits resulting in improved performance.
